Politicians dither as climate crisis builds

 

GLOBAL heating appears to have entered a new and fast-moving trajectory. Amid record-breaking temperatures, melting ice and a sharp increase in North Atlantic sea surface temperatures during the month of July, veteran climate scientists are now becoming increasingly alarmed about the pace of change.

“A few decades ago some people might have thought climate change was a relatively slow-moving phenomenon but we are now witnessing things happening at a terrifying rate,” said Prof Peter Stott, leader of the UK Met Office’s climate monitoring and attribution team.

The World Meteorological Organization (WMO) has also warned of record temperatures and extreme heat in the near future after confirming the latest climate-heating El Niño event had “arrived”.

The last major El Niño was in 2016 – which to date remains the hottest year on record. But for 2023, it comes on top of increasing global heat driven by human-caused carbon emissions, an effect described by the WMO as a “double whammy”. Its officials say urgent preparations for extreme weather events are now vital to save lives and livelihoods.

“As El Niño builds through the rest of this year, adding an extra oomph to the damaging effects of human-induced global heating, many millions of people across the planet and many diverse ecosystems are going to face extraordinary challenges – and unfortunately suffer great damage,” added Stott.

The WMO estimates there is now a 90 percent probability of the latest El Niño continuing to the end of 2023 at a moderate strength or higher, with the added risk of it supercharging extreme weather.

New records for high temperature have been broken almost daily on every continent in recent months whilst in the UK, the average temperature for June was beaten by nearly a full degree with an unprecedented heatwave also affecting the country’s coastal waters.

Peter Kalmus, a climate scientist at NASA’s Jet Propulsion Laboratory in California, admits that he doesn’t fully understand what’s going on with this summer’s crazy climate data.

“It feels to me like the climate may have shifted into some sort of new regime of global heating that scientists don’t yet understand. And yet the media and everyone keep acting like things are basically fine and leaders keep expanding fossil fuels,” he says.

Cambridge University’s Prof Emily Shuckburgh, a leading climate scientist and director of Cambridge Zero, says that after the UK’s record-breaking month of high temperatures, it looks likely the rest of the summer will be warmer than normal too as global temperatures continue to rise.

“We’ve been warning of these changes for 30 years and warning that the planet is overheating,” she told listeners on BBC’s Radio 4 Today programme (3 July 2023).

“We’ve got record melting in Greenland occurring right at this moment, we’ve got record low levels of sea ice in Antarctica. From pole to pole we are seeing dramatic changes and it is nature as well as humans that is witnessing the impact.

“Those extreme temperatures of 40 degrees that we saw in the UK last summer had a dramatic impact on our wildlife and a dramatic impact on us. Across Europe thousands of people died prematurely in that heatwave.

“Sadly the UK used to be a global leader in terms of climate change and it was only two years ago that we hosted the big international climate conference COP-26. We’ve now relinquished that leadership.”

Prof Shuckburgh says the recent progress report from the UK Government’s Climate Change Committee (CCC) on how the UK is doing against its own decarbonisation plans was “covered with red” because goals and targets were not being met.

“We should be responding to the cost of living and energy crisis by investing in insulation, in solar, in wind, offshore and onshore,” she suggested.

Prof Shuckburgh urged people to accept the global scale of what is at risk. “We know that if we don’t respond to climate change as a country and as a world then the risks are enormous,” she said.

“They are potentially catastrophic in terms of our food supplies, the global spread of disease, the risk from migration by communities that have been impacted by climate change, the risk of conflicts and, most importantly of all, the risk of passing catastrophic tipping points.

“This is what’s at stake. The really frustrating thing from my perspective is that we know what the solutions are. We have them at our fingertips and what we need are stable policies in support of them.”

Such stark warnings are echoed by the UN High Commissioner for Human Rights, Volker Turk, who also described addressing climate change as a “human rights” issue.

Evoking a “dystopian future” if urgent action isn’t taken, he said: “Our environment is burning. It’s melting. It’s flooding. It’s depleting. It’s drying. It’s dying. We, the generation with the most powerful technological tools in history, have the capacity to change it.”

He accused world leaders of performing “the choreography of promising to act” before getting stuck in a rut dominated by short-term political expediency. Turk called for an immediate end to “senseless subsidies” of the fossil fuel industry and said the Dubai COP28 (2023 UN Climate Change Conference) climate summit in November and December needs to be a “decisive game-changer”.

At the end of June, British Prime Minister Rishi Sunak was accused by a resigning government minister and environment campaigner, Zac Goldsmith, of being “simply uninterested” in the environment and climate emergency.

Lame political leadership – mirrored by many of those in power and supported by the fossil fuel industry and elements of the right-wing media – along with a cost-of-living crisis and war in Ukraine, have all contributed to a prevailing laissez faire attitude.

At the start of 2023, when Sunak introduced his five key policy pledges, the climate and environment were noticeable by their absence, a clear indication that the country’s third prime minister in as many years does not view them as a priority.

Nothing has changed and, despite mounting climate relasted emergencies around the world this summer, Sunak, who favours flying about the country on short-haul private jets and helicopters, also shunned a recent Paris summit on the climate, debt and poverty hosted by the French President Emmanuel Macron.

If there can be a final thought and persepctive (for now) on this challenging issue then perhaps, somewhat surprisingly, it might go to the actor William Shatner.

As Captain James T Kirk of Star Trek’s Enterprise spaceship he explored the universe, espousing a vision of the future where humanity had not only survived but overcome many of the Earthly problems we face today.

Last year, 90-year-old Shatner had what he described as a “life-changing experience” when he physically travelled into space for the first time, expecting to experience “a deep connection with the immensity around us” and “a deep call” for endless exploration.

“The strongest feeling I had, that dominated everything else by far, was the deepest grief I have ever experienced. I understood, in the clearest possible way, that we were living on a tiny oasis of life, surrounded by an immensity of death,” he said.

“I didn’t see infinite possibilities of worlds to explore, of adventures to have, or living creatures to connect with. I saw the deepest darkness I could have ever imagined, contrasting starkly with the welcoming warmth of our nurturing home planet.

“This was an immensely powerful awakening for me. It filled me with sadness. I realised that we had spent decades, if not centuries, being obsessed with looking away, with looking outside.

“I did my share in popularising the idea that space was the final frontier. But I had to get to space to understand that Earth is and will stay our only home. It is the final and only frontier, and we have been ravaging it relentlessly, destroying it at an unprecedented rate and making it uninhabitable.”

Pumping up the weather


THE year 2022 effectively tied for Earth’s fifth warmest year since 1880 - and the last nine consecutive years have been the warmest nine on record, according to the latest analysis released by NASA.

Scientists from the Goddard Institute for Space Studies (GISS), NASA’s leading centre for climate modelling in New York have reported global temperatures in 2022 were 0.89 degrees Centigrade (C) above the average for NASA’s baseline period (1951-1980), continuing the planet’s long-term warming trend. Earth is now about 1.11 degrees C warmer than the late 19th century average.

“This is alarming,” admits NASA Administrator Bill Nelson, a former Space Shuttle astronaut. “Our warming climate is already making a mark. Forest fires are intensifying, hurricanes are getting stronger, droughts are wreaking havoc and sea levels are rising.”

He says NASA is deepening its commitment to addressing climate change and adds: “Our Earth System Observatory will provide state-of-the-art data to support our climate modelling, analysis and predictions to help humanity confront our planet’s changing climate.”

“The reason for the warming trend is that human activities continue to pump enormous amounts of greenhouse gases into the atmosphere, and the long-term planetary impacts will also continue,” explains Gavin Schmidt, director of GISS.

NASA scientists, working with leading international climatologists, have determined carbon dioxide emissions were the highest on record in 2022, despite a short-lived dip in 2020 due to the Covid-19 pandemic. Levels of these human-driven greenhouse gas emissions have rebounded since.

Using the Earth Surface Mineral Dust Source Investigation instrument that launched to the International Space Station last year, they have also identified some super-emitters of methane – another powerful greenhouse gas.

Earth’s Arctic region continues to experience the strongest warming trends – close to four times the global average – according to GISS research presented at the 2022 annual meeting of the American Geophysical Union, as well as in a separate study.

Communities around the world are already experiencing the impacts that scientists see as connected to the warming atmosphere and ocean – intensified rainfall and tropical storms, severe droughts and increased storm surges.

Among many other climate-driven weather events around the world – including the UK’s hottest ever daytime temperatures which peaked at 40.3 C in Coningsby, Lincolnshire – last year brought torrential monsoon rains that devastated Pakistan and a persistent megadrought in the US Southwest. In September, Hurricane Ian became one of the strongest and costliest hurricanes to strike the continental US.

NASA’s global temperature analysis is drawn from data collected by weather stations and Antarctic research stations, as well as instruments mounted on ships and ocean buoys.

Scientists analyse these measurements to account for uncertainties in the data and to maintain consistent methods for calculating global average surface temperature differences for every year. These ground-based measurements of surface temperature are consistent with satellite data collected since 2002 by the Atmospheric Infrared Sounder on NASA’s Aqua satellite and with other estimates.

NASA uses the period from 1951-1980 as a baseline to understand how global temperatures change over time. That baseline includes climate patterns such as La Niña and El Niño, as well as unusually hot or cold years due to other factors, ensuring it encompasses natural variations in Earth’s temperature.

Many factors can affect the average temperature in any given year. For example, 2022 was one of the warmest on record despite a third consecutive year of La Niña conditions in the tropical Pacific Ocean.

NASA scientists estimate that La Niña’s cooling influence may have lowered global temperatures slightly (about 0.06 degrees C) from what the average would have been under more typical ocean conditions.

A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that the global surface temperature for 2022 was the sixth highest since 1880.

NOAA scientists use much of the same raw temperature data in their analysis and have a different baseline period (1901-2000) and methodology. Although rankings for specific years can differ slightly between the records, they are in broad agreement and both reflect ongoing long-term warming.

NASA’s full dataset of global surface temperatures through 2022, as well as details with code of how NASA scientists conducted the analysis, are publicly available from GISS

NASA's real-life "Don't Look Up"


ENTERTAINING and a bit worrying at the same time, the movie Don’t Look Up defied critics and broke Netflix’s record for the most hours viewed in a single week on the global TV platform at the start of the year.

It tells the story of astronomy graduate Kate Dibiasky (Jennifer Lawrence) and her PhD adviser, Dr Randall Mindy (Leonardo DiCaprio), who discover a “planet killer” comet that will impact Earth in just over six months.

The movie’s rogue comet could be anything – climate change, new viruses, global war, attempts to overthrow a legitimate democracy – and the scientists are essentially alone
with their knowledge, ignored and gas-lighted by society, and ridiculed by the media.

The film is both amusing and terrifying in equal measure, conveying uncomfortable cold truths and demonstrating how hard it is to break through prevailing norms.

Above all, it perfectly captures humanity’s apparent capacity for denying the blindingly obvious, the absurdity of an economic system which puts profit above survival of life on earth, a crass political class, and a superficial mainstream media more concerned with show biz stars and ratings.

Don’t Look Up is most definitely a movie for our time. And do hang around to watch all the credits as there are some interesting bits right at the very end! 

In real life, the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) - a state-of-the-art asteroid detection system operated by the University of Hawaiʻi (UH) Institute for Astronomy (IfA) for the agency’s Planetary Defense Coordination Office (PDCO) - reached a new milestone in February by becoming the first survey capable of searching the entire dark sky every 24 hours for near-Earth objects (NEOs) that could pose a future impact hazard to Earth.

Now involving four telescopes, ATLAS has expanded its reach to the southern hemisphere from the two existing northern-hemisphere telescopes on Haleakalā and Maunaloa in Hawai’i to include two additional observatories in South Africa and Chile.

“An important part of planetary defence is finding asteroids before they find us, so if necessary, we can get them before they get us” said Kelly Fast, NEO Observations Program Manager for NASA’s Planetary Defense Coordination Office.

“With the addition of these two telescopes, ATLAS is now capable of searching the entire dark sky every 24 hours, making it an important asset for NASA’s continuous effort to find, track, and monitor NEOs.”

Each of the four ATLAS telescopes can image a swath of sky 100 times larger than the full Moon in a single exposure. The completion of the two final telescopes, which are located at Sutherland Observing Station in South Africa and El Sauce Observatory in Chile, enable ATLAS to observe the night sky when it is daytime in Hawai‘i.

To date, the ATLAS system has discovered more than 700 near-Earth asteroids and 66 comets, along with detection of 2019 MO and 2018 LA, two very small asteroids that actually impacted Earth.

The system is specially designed to detect objects that approach very close to Earth - closer than the distance to the Moon, about 240,000 miles away. On 22 January, ATLAS-Sutherland in South Africa discovered its first NEO, 2022 BK, a 100 m asteroid that poses no threat to Earth.

The addition of the new observatories to the ATLAS system comes at a time when the agency’s Planetary Defense efforts are on the rise. 

NASA’s Double Asteroid Redirection Test (DART) - the world’s first full-scale mission to test a technology for defending Earth against potential asteroid impacts - launched last November will deflect a known asteroid, which is not a threat to Earth, to slightly change the asteroid’s motion in a way that can be accurately measured using ground-based telescopes.

Additionally, work on the agency’s Near-Earth Object Surveyor space telescope (NEO Surveyor) is underway after receiving authorisation to move forward into Preliminary Design. 

Once complete, the infrared space telescope will expedite the agency’s ability to discover and characterise most of the potentially hazardous NEOs, including those that may approach Earth from the daytime sky.

Paving the road to living in space


A MINDSET anchored within endeavours of the past and established ways of doing things is one of the most significant obstacles to humanity’s space-faring future.

Five decades after the first Moon landing, most major space agencies and all but a handful of private launch companies remain focused on the on-going development of expendable launchers or, at best, only partly reusable launchers.

Undoubtedly today’s rockets are more efficient than their predecessors. But are their inherent inefficiencies truly the way to herald a new golden age of space exploration?

The expendable rocket mindset is one of the biggest remaining barriers to a new Space Age and, if the new US Moon programme is to lead to a ‘permanent’ lunar endeavour, economic and environmental sustainability are paramount. This means leaning towards low-cost, practical and private-sector driven solutions which have the potential to create profitable and sustainable new business opportunities.

NASA’s Space Launch System (SLS), for example, is hardly ground-breaking or inventive - more a product of linear, stop-start development. Of course, it benefits from advanced technology and engineering but, five decades after Saturn V, it lacks true innovation and the spark of commercial endeavour.

The agency has spent about US$14 billion on its super rocket and related development costs since 2010 but SLS is not expected to fly before at least mid- to late 2021. In contrast, SpaceX privately developed its mostly reusable Falcon Heavy rocket on the back of its Falcon 9 for about US$500 million, and has flown three successful missions since February 2018.

Likewise, Sierra Nevada’s Dream Chaser is the only existing commercial spaceplane in the world that is both fully reusable and capable of a runway landing. Despite this NASA still only wants to use it for the transfer of cargo to the International Space Station.

At a time when reusability, in every sense of the word, should be at the forefront, agencies such as NASA (SLS), ESA (Ariane 6), Roscomsos (Soyuz), JAXA (H-IIB) and ISRO (GSLV) seem intent on pursuing the expendability route to orbit, albeit with a modern technical twist.

Do projects like SLS cast us far enough into the future or, in some perverse way, do they limit our future ambitions? The future of space and human exploration is intrinsically intertwined with our future on Earth itself. It should not be owned by politics and politicians but by risk-takers and the visionary.

Bright lights in the sky

The Chelyabinsk asteroid over Russia in February 2013.
THERE'S been significant worldwide media interest in tomorrow morning’s flyby of asteroid 2012 TC4, which will make an unusually close pass to Earth at a distance of just 43,780 km -  that’s well inside the orbit of the Moon and closer than some satellites.

"We know the orbit of TC4 well enough to be absolutely certain that it won't hit Earth," assures Paul Chodas, manager of the Center for Near-Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory in California,"but we haven't established its exact path just yet."

The chunk of space rock is about as big (in the range of 10-20 m diameter) as the famous 2013 Chelyabinsk object which hit Earth without warning as the sun  rose over Russia’s Ural mountains on 15 February 2013.

As the space rock skimmed into the atmosphere the early morning sky lit up with a second ‘sun’ as shock waves shattered windows in hundreds of buildings around the wakening city.

It had impacted Earth literally ‘out of the blue’, flying in from the direction of the sun where no telescope could see it - and it took everyone by surprise.

Years later, meteorite hunters are still finding pieces of the ‘Chelyabinsk asteroid’ that rained down after its 17 m-wide body disintegrated in the atmosphere.

The difference with 2012 TC4, which could be up to 30 m wide, is that NASA knows it's coming. At 07:41 CEST (Central European Summer Time) tomorrow morning (12 October) it will pass 43,500 km above Earth’s surface, about 1/8th the distance to the Moon.

The flyby is so close, gravity will significantly alter the asteroid's trajectory before it exits the Earth-Moon system.

To get a better handle on the asteroid's orbit (and possible future encounters), an international network of telescopes will monitor 2012 TC4 as it speeds by.


Pinging the asteroid with its Goldstone telescope, NASA also hopes to learn much about the space rock's physical properties.

This asteroid is too small to see with the naked eye. However, skilled amateur astronomers using small telescopes will be able to observe it. At peak brightness, 2012 TC4 will shine like a 13th magnitude star as it zips through the constellations Capricornus and Sagittarius.

The house-sized space rock does afford space agencies across the globe an opportunity to test some of their planetary defence scenarios that might be needed if Earth was in the path of a more dangerous asteroid.

If an asteroid the size of TC4 or slightly bigger was on course to hit a populated area, agencies such as the ESA and NASA would look to warn people and work with relevant governments to potentially start an evacuation.

If anything signifcantly bigger the TC4 is ever detected, much more drastic action might be needed, including the possibility of trying to deflect any such asteroid before it collides with Earth.

Back to the future


 Photos: Nasa
Today's first-ever test flight of NASA's Orion deep-space capsule is all about the future of America's space effort - but it's also about reviving the past.

"I feel like the Blues Brothers - we're getting the band back together," Bob Cabana, director of NASA's Kennedy Space Center, told a pre-launch news conference in front of Orion's Florida launch pad.

After a 24 hour launch delay the Delta IV Heavy and Orion cleared the tower in just a few seconds to begin a carefully choreographed climb skyward.

The core stages on either side of the rocket burned their propellants and fell away at T+3minutes, 56 seconds. The central core stage continued for another 94 seconds as the rocket and spacecraft climbed higher and picked up more speed. The first stage fell away and the second stage took over to put Orion into an initial orbit of 115 miles by 552 miles.

Orion is Nasa’s successor to the Space Shuttle and the agency hopes it will take humans further into space than ever before, possibly as far as Mars. The test flight is the start of a “new chapter in human space exploration”, the agency says.

Primary purpose of the mission was to test a new 16 foot wide heat shield aimed at protecting the capsule, which can carry up to six astronauts. After two orbits, Orion plunged to Earth off the coast of Baja, California, travelling at 20,000 mph and generating 2,200 C as it plunged through the atmosphere.

Nasa confidently asserts that Orion will send people to an asteroid and onward to Mars, but the first astronauts are not scheduled to travel in it for at least seven years, which is a long time in space politics.

Even this crew-less outing - known as Exploration Flight Test 1 (EFT-1) - carried echoes of Apollo. The 4.5 hour trip sent Orion 3,600 miles out from Earth, the farthest that a spacecraft meant for humans has flown since 1972.

And it splashed down in the Pacific Ocean - just like NASA's last Apollo spaceship that returned to Earth at the end of the Apollo-Soyuz Test Project in 1975.

For NASA, even the fact that people are paying attention to the Orion test flight comes as a welcome blast from the past. The space agency said more than 500 journalists were accredited to cover the launch, which is more than for any other Florida launch since the Shuttle fleet's retirement.


Orion is being developed by Lockheed Martin alongside a powerful new rocket that will have its own debut in three or four years' time. Together, they will form the core capabilities needed to send humans beyond the International Space Station (ISS).

Today's flight therefore was on a stand-in Delta IV-Heavy rocket - currently the largest US launcher which duly delivered a fiery launch spectacle to the millions of people watching Nasa’s live internet broadcasts.

At this point immediately after the mission it seems that just about everything worked perfectly. The test will go down as a huge success as analysing the data begins in earnest.

However, in the background, there are still worries about the strength of political commitment  underpinning to the Orion programme - and any resulting lack of money could mean the momentum of successive missions becomes hard to maintain.
       
Space rarely seems to be out of the news these days. Hot on the heels of last month’s Rosetta and the inspiring  Philae comet lander we've also had an ESA ministerial meeting (at which decisions are made on the funding of future European space programmes) this week .

The UK has committed over £50 million to the project that has an estimated price tag of €340 million. But with promises extending to €180 million for funding, the ExoMars plan is still short of all the funds it needs.

According to ESA's pragmatic director general Jean-Jaques Dordain that is more than enough to be getting on with, thank you very much. It means that Britain will likely take the lead and build the rover on these shores.

The government's pledge to the ExoMars programme amounts to £55 million, alongside a similar amount to help keep the Space Station operating in orbit. This more than triples the sum offered as a ‘one-off' payment to the ISS two years ago.

Eager to join the positive band wagon, even George Osborne managed to work in a quip or two about Mars exploration and his great support for space when introducing his budget deficit this week in the House of Commons.

Joking at the expense of the opposition benches, Mr Osborne said: "We on this side of the house have often gazed at the barren and desolate wastelands of the red planet. We have long given up hope of finding intelligent life there. But signs of any life at all would be a major advance."

The country's growing space industry is at last getting the recognition and investment it needs - not just ‘because it is there’ but because politicians now recognise it is a pretty shrewd investment for the country as a whole.

Credit must be given to all political parties. The good work in space was started by the last labour government and has been continued by the coalition in a true example of what joined up, long-term thinking should be about. If only this could be applied in other areas - like the country's energy policy.

It does remain to be seen, however, whether Nigel Farage and his Ukip brigade have anything like a space plan scribbled on the back of a fag packet should they get anywhere near the final countdown during next May's elections. I guess we just have to say, ‘watch this space’.

Countdown to launch


Launch of the first flight test of Orion, NASA’s next-generation spacecraft that will send astronauts to an asteroid and onward to Mars, is now less than an hour away.

The Orion will launch, uncrewed, on a United Launch Alliance Delta IV-Heavy rocket at 0705 local time (1205 GMT) from Space Launch Complex 37 at Cape Canaveral Air Force Station (CCAFS) in Florida.

The window for launch is two hours and 39 minutes, and weather at both the launch and splashdown sites is currently showing ‘green’.

During its 4.5 hour trip, Orion will orbit Earth twice and travel to an altitude of 3,600 miles into space.

The flight is designed to test many of the elements that pose the greatest risk to astronauts and will provide critical data needed to improve Orion’s design and reduce risks to future mission crews.

United Launch Alliance operates the Delta IV-Heavy, the largest rocket in the American launch inventory.

The first stage includes three core stages, each one 134-feet-tall and 16.7 feet in diameter. An RS-68 engine is at the base of each core stage to give the rocket a combined thrust of about two million pounds.

The stage holds super-cold liquid oxygen and liquid hydrogen propellants. The second stage of the Delta IV Heavy is powered by a single RL10B-2 engine that also uses a combination of liquid hydrogen and liquid oxygen. The Orion spacecraft is bolted to the top of the second stage.


The Spaceflight Meteorology Group at Johnson Space Center is saying the weather looks good off the coast of Baja, California, where Orion will descend and splashdown to end the flight test. Navy ships are waiting in the area to recover the Orion spacecraft.

Live coverage of the launch from Nasa can be viewed by clicking here

Ready for blast off


Sunrise at Kennedy Space Center in Florida and a new era is about to begin. Today is probably Nasa’s biggest day since the final Space Shuttle launch in July 2011.

There are no people on today’s test flight of Orion, the capsule that is planned to take humans once again beyond the confines of Earth into deep space. Whether such a small capsule will ever make it as far as Mars is another question.

Launch weather officer Kathy Winters says conditions “are promising” with a 70 per cent prospect of favourable weather for the opening of the early morning (1205 GMT) launch window.

Heading into the final hours of countdown the mood in Houston mission control is upbeat. “On the vehicle side everything is extremely clean. We're ready to go,” says Mark Geyer, NASA's Orion programme manager.

Flight director Mike Serafin hasn’t experienced this kind of feeling around Nasa since the end of the Space Shuttle programme. “We are launching an American spacecraft from American soil and beginning something new,” he says.

“It’s a new mission and there are some things I'm sure we're going to learn from this unmanned flight test that will enable us to fly humans into deep space.”

With the launch of Orion, Nasa is about to claw back some of the ground it lost after the premature cancellation of the Space Shuttle programme by President Bush when there was nothing on hand to replace it.

The short, unmanned flight of Orion - a conical vessel reminiscent of the Apollo command modules that carried men to the Moon in the 1960s and 1970s - will test key technologies.

Orion is being developed by Lockheed Martin alongside a powerful new rocket that will have its own debut in three or four years’ time. Together, they will form the core capabilities needed to send humans beyond the International Space Station (ISS).

Today’s flight will be on a stand-in Delta IV-Heavy rocket - currently the largest launcher in the world and so the blast off will be spectacular.

Shortly after midnight local time the 330-foot tall mobile service tower was retracted from Cape Canaveral's pad 37B and the wheeled gantry structure moved along rail tracks to its launch position about the length of a football field away from the rocket.

Crews then worked on securing the complex for launch before leaving the danger area around the pad.

All workers had to be clear prior to the start of hazardous operations in the countdown - which include fuelling the Delta IV's Common Booster Cores and the second stage with supercooled liquid oxygen and liquid hydrogen propellants - which began shortly before 3 am.

Astronaut's view of Earth


The world’s biggest and most spectacular reality show is now available on a laptop, tablet or TV screen near you.

Live pictures from Earth orbit can now be viewed by anyone with an internet connection thanks to NASA’s latest experiment on the International Space Station (ISS).

The High Definition Earth Viewing Experiment (HDEV) started its round-the-clock broadcasts on 30 April and will stream video of Earth from the orbiting Space Station until October 2015.

Footage of Earth is captured by four cameras attached to the outside of the ISS as part of an experiment to evaluate whether commercially available cameras can survive the harsh conditions of space, particularly high levels of radiation.

The cameras - enclosed in a pressurised box containing dry nitrogen to mimic atmospheric pressure on Earth - are mounted on the External Payload Facility of ESA’s Columbus module.

NASA hopes it will be able to use similar, commercially available HD video cameras on future space missions as this will likely be more cost-effective than designing new products.

Video from these cameras is transmitted back to Earth and then streamed live on this ustream tv link - with views typically sequencing though the different cameras.


Viewers should also be aware that this is real space so there is no sound (in space no one can hear you scream) and there are a few quirks to be aware of (please do no adjust your set).

Between camera switches, a grey and then black colour slate briefly appears and, since the ISS is in darkness during part of each orbit, pictures at those times will be dark.

Also, during periods of loss of signal with the ground, or when HDEV is not operating, a grey colour slate or previously recorded video may be seen.

And remember, because the Space Station orbits Earth every 90 minutes there is a sunrise or sunset every 40 minutes.

Analysis of this experiment will be conducted to assess the effects of the space environment on the equipment and video quality which may help decisions about cameras for future missions.

Space without frontiers

Preparations for tomorrow morning’s landing in Kazakhstan of two Russian cosmonauts and an American astronaut continue unabated against a backdrop of increasing tensions over Russia's armed incursion into Ukraine.

And NASA is once again confronted with the nightmare of a potential diplomatic roadblock thanks to its reliance on Russia for transporting its astronauts to Earth orbit and back.

Nearly two dozen NASA officials and medical personnel are in Kazakhstan to greet the three man crew, which is led by veteran Russian commander Oleg Kotov, a native of the Crimea region.

The NASA team joins the Russian-led recovery crew, a fleet of helicopters, fixed-wing surveillance aircraft and all-terrain ground vehicles to quickly reach the Soyuz capsule after it parachutes to Earth.

This month's comings and goings at the International Space Station (ISS) highlight the interdependence of the US and Russian space efforts.
 
Just two weeks after tomorrow’s landing NASA's Steven Swanson is to ride another Russian Soyuz craft up to the station, again in the company of two Russians.

Under current arrangements, NASA astronauts can only get to and from the ISS with Russian help, due to the retirement of the Space Shuttle fleet in 2011 before an alternative US launcher was in place. Russia charges NASA $70 million for each astronaut round trip.

If Russia's confrontation with Ukraine and the West does develop into the worst diplomatic crisis of our generation it could have potential consequences for space exploration, though based on past experience it looks unlikely - at least for the timing being.

NASA Administrator Charles Bolden stated last week that the space station programme had so far been “resilient to international crises” since Russian formally joined the effort in 1993.

"I think people lose track of the fact that we have occupied the ISS now for 13 consecutive years uninterrupted, and that has taken us through multiple international crises," he said.

The three returning space farers – Kotov, his fellow Russian cosmonaut Sergey Ryazanskiy and NASA astronaut Michael Hopkins - have now completed their final weekend of a 166-day mission aboard the ISS.

They launched from the Baikonur Cosmodrome in Kazakhstan on 25 September and arrived at the 450-ton orbiting outpost six hours later.

The first phase of their return to Earth starts this evening when they will enter their Soyuz TMA-10M capsule and close hatches with the space station at around 2045 GMT.

Undocking is set for two minutes after midnight, followed by a burn of the Soyuz rocket thrusters at 0230 GMT to slow the craft's velocity enough to fall back into the atmosphere.

Touchdown - southeast of the town of Dzhezkazgan in Kazakhstan - is scheduled for 0324 GMT (0924 am local time at the landing site).

Warming trend continues

Lord Stern, who completed a review of the economics of climate change for the British government in 2006, says he should have been fiercer in his report.

Speaking at the start of the World Economic Forum in Davros, Switzerland, this week he said governments are “fooling themselves” if they think global temperature rises will only have modest economic impacts.

Stern says things have moved on in the eight years since his review. "I would have been much fiercer,” he admits. "Emissions have gone up faster than I thought and some of the effects of global warming are coming through more quickly, such as melting of the glaciers and the polar ice caps.”

He estimates global temperatures will be 4-5 C higher in the next century on present trends and that governments are being unrealistic if they think this will only have a modest impact on economies.

"The last time we had a change in global temperatures of this order of magnitude it was in the other direction. It was called the Ice Age,” Stern added.

According to new figures released by NASA the year just past tied with 2009 and 2006 for the seventh warmest year since 1880, continuing the long-term trend of rising global temperatures.

With the exception of 1998, the 10 warmest years in the 134 year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

NASA's Goddard Institute for Space Studies (GISS) in New York, which analyses global surface temperatures on an ongoing basis, released an updated report this week on temperatures around the globe in 2013. 

The comparison shows how Earth continues to experience temperatures warmer than those measured several decades ago.

The average temperature in 2013 was 14.6 Celsius, which is 0.6 C warmer than the mid-20th century baseline. The average global temperature has risen about 0.8 C since 1880, according to the new analysis. Exact rankings for individual years are sensitive to data inputs and analysis methods.

"Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change," said GISS climatologist Gavin Schmidt at a NASA press conference on Tuesday.

"While one year or one season can be affected by random weather events, this analysis shows the necessity for continued, long-term monitoring.”

Scientists emphasise that weather patterns will always cause fluctuations in average temperatures from year to year but say the continued increases in greenhouse gas levels in Earth's atmosphere are driving a long-term rise in global temperatures. 

Each successive year will not necessarily be warmer than the year before, but with the current level of greenhouse gas emissions, scientists expect each successive decade to be warmer than the previous.

Carbon dioxide is a greenhouse gas that traps heat and plays a major role in controlling changes to Earth's climate. It occurs naturally and is also emitted by the burning of fossil fuels for energy. 

Driven by increasing man-made emissions, the level of carbon dioxide in Earth's atmosphere at present is higher than at any time in the last 800,000 years.

The carbon dioxide level in the atmosphere was about 285 parts per million in 1880, the first year in the GISS temperature record. By 1960, the atmospheric carbon dioxide concentration, measured at the National Oceanic and Atmospheric Administration's (NOAA) Mauna Loa Observatory in Hawaii, was about 315 parts per million. This measurement peaked last year at more than 400 parts per million.

While the world experienced relatively warm temperatures in 2013, the continental United States experienced the 42nd warmest year on record, according to GISS analysis. For some other countries, such as Australia, 2013 was the hottest year on record.

The temperature analysis produced at GISS is compiled from weather data from more than 1,000 meteorological stations around the world, satellite observations of sea-surface temperature and Antarctic research station measurements, taking into account station history and urban heat island effects. 

Software is used to calculate the difference between surface temperature in a given month and the average temperature for the same place from 1951 to 1980. This three-decade period functions as a baseline for the analysis. It has been 38 years since the recording of a year of cooler than average temperatures.

The GISS temperature record is one of several global temperature analyses, along with those produced by the Met Office Hadley Centre in the UK and NOAA's National Climatic Data Center in the US. These three primary records use slightly different methods but overall their trends show close agreement.

Sleeping satellite

If all goes to plan China’s Chang'e 3 probe will land on the Moon at the end of next week and open up a new era of lunar exploration.

The mission is a symbol of China's power and prowess. But look behind the political smokescreen and there is a sharp commercial edge to the country’s space ambitions.

Forty plus years ago it was the United States that inspired a generation growing up in the 1960s by making the ‘giant leap’ from Earth to the Moon.

Capitalism proved it could be first but it was more of a means to an end and became politically unsustainable even before the last men left the Moon in 1972.

How fortunes have changed. Communist China is now the world’s leading and most buoyant economy and has its sights set firmly on the opportunities presented by our nearest planetary neighbour.

Chang'e 3 is scheduled to land on 14 December in a region known as Bay of Rainbows, or Sinus Iridum, located on the upper-left part of the full Moon as viewed from Earth.

The mission blasted off from Xichang in the south of the country at 17.30 GMT on Sunday (1 December) and the spacecraft’s landing module includes a six-wheeled robotic rover called Yutu (translated as Jade Rabbit).



It will be China's first lunar rover as well as becoming the first spacecraft since the Soviet Luna 24 mission in 1976 to make a soft landing on the Moon,

According to information released by its design company the Shanghai Aerospace Systems Engineering Research Institute, the 120 kg Jade Rabbit rover can climb slopes of up to 30 degrees and travel at 200 m per hour.

Its name - chosen in an online poll of 3.4 million voters - derives from an ancient Chinese myth about a rabbit living on the Moon as the pet of the lunar goddess Chang'e.

Both the rover and lander are powered by solar panels but some sources suggest they also carry radioisotope heating units (RHUs) containing plutonium-238 to keep them ‘warm’ during the cold lunar night.

The mission - which will explore the Moon's surface and search for evidence of natural resources such as rare metals - carries a sophisticated payload, including ground-penetrating radar which will gather measurements of the lunar soil and crust.




It marks a milestone in China's ambitious long-term space exploration programme, which includes establishing a permanent space station in Earth orbit.

Future planned launches include a flight to bring back samples of lunar soil to Earth and ultimately sending Chinese nationals to the Moon, in what would likely be the first manned lunar missions since the US Apollo programme in the late 1960s and 1970s.

China knows the Moon is full of plunder that is there for the taking - mainly rare earth elements like titanium and uranium that Earth is really short of. And one day these valuable resources can be mined without limitation.

With NASA currently lacking even its own rocket and relying on the Russians to transport its astronauts to the International Space Station (ISS) it seems, in the words of the chart-topping song ‘Sleeping Satellite’, that the West may have ‘peaked too soon’.

It was the debut single by the British singer-songwriter Tasmin Archer and, in the light of China’s Moon mission and ambitious plans, the lyrics are more poignant than when it was released in 1992.

I blame you for the moonlit sky and the dream that died with the eagles' flight; I blame you for the moonlit nights when I wonder why are the seas still dry? Don't blame this sleeping satellite.
Did we fly to the moon too soon; did we squander the chance in the rush of the race; the reason we chase is lost in romance; and still we try to justify the waste for a taste of man's greatest adventure.

"It's not intended as anti-space travel," says Archer. "It's just the opposite and bemoans the fact that at the time of the anniversary the initiative had not been progressed from the original achievement."

The US may never quite catch up again and will probably one day rue the decision made by its politicians not to re-visit our ‘Sleeping Satellite’ sooner. Perhaps Archer is right and they did peak too soon - and lost a collective sense of adventure in the process.

Message in a bottle

Give or take a few miles, a 36-year-old unmanned spacecraft is now about 12 billion miles from the Sun, a pretty incomprehensible distance whichever way you look at it.

And this week NASA's Voyager 1 spacecraft officially became the first human-made object to venture into interstellar space.

New data gathered during the summer indicate Voyager 1 has now been travelling for about one year through the plasma (ionized gas) of interstellar space, the space between stars.

Covering nearly a million miles a day, the nuclear-powered spacecraft, has well and truly crossed the boundary between the Sun's influence and interstellar space, sailing into the vast gulf between the stars to become humanity's first true starship.

The announcement was made this week by scientists at NASA’s JPL in California, including Voyager project scientist Ed Stone.

"In leaving the solar system and setting sail on the cosmic seas between the stars, Voyager has joined the other historic journeys of exploration such as the first circumnavigation of the Earth and the first footprint on the Moon," he said.

"This historic step is even more exciting because it marks the beginning of a new era of exploration for Voyager, the exploration of the space between the stars."

It may be a new era of exploration for humankind but in reality we’ll get only limited information from Voyager, partly because of the vast distances involved and also because its instruments are being to wear out.

The fact that some are working even now is testament to the robust design of a spacecraft that was only ever meant to gather data from a spectacular journey through the giant planets of our solar system.

Voyager 1 reached the boundary of the heliosphere in 2004, a milestone marked by readings showing the speed of the solar wind had dropped below that of sound. But it took another nine years to complete the crossing and move out into interstellar space.

The actual transition likely occurred in August last year but an instrument that would have confirmed that failed in 1980, forcing scientists to rely on less direct methods of observation.

As it turned out, the Sun cooperated, blasting huge clouds of charged particles and magnetic energy in Voyager 1's direction in March 2012. When the particles finally got there 13 months later, they created detectable vibrations in the electrically charged plasma surrounding the spacecraft.

After studying those waves, scientists concluded the density of the material was 40 times higher than it would be if Voyager 1 was still in the heliosphere.

The heliosphere is defined by the Sun's magnetic field and is filled with electrically charged particles blasted away from the Sun in all directions -- the solar wind.

Our Sun, its planets, moons, asteroids and comets are embedded in a vast, t teardrop-shaped region, or bubble, in space known as the heliosphere.

Voyager 2 was launched on 20 August 1977 and Voyager 1 lifted off on 5 September the same year. Both probes carry gold discs with recordings designed to portray the diversity of culture on Earth - just incase they are ever intercepted by distant intelligent life forms.

The probes were launched on different trajectories. Voyager 2′s so-called 'slow' trajectory enabled it to visit all four giant planets, while Voyager 1′s faster trajectory meant it would head into deep space after visiting Jupiter and Saturn.

Voyager 1 is now the furthest human-built object from Earth and the distance is so vast that it takes 17 hours now for a radio signal sent from Voyager to reach receivers on Earth.

It is expected that their plutonium power sources will stop supplying electricity in about 10 years, at which point their instruments and 20W transmitters will die. After that Voyager 1 will not approach another star for nearly 40,000 years.

When Voyager 1 blasted into space the world we live in was a very different place and much has changed in the intervening decades, both socially and from a technological perspective.

The Voyager spacecraft was designed to run most of its operations itself and computing power was impressive for its time.

Each probe has three interconnected computer systems: one to control the craft’s flight and altitude, another to control its instruments, and a third to manage the first two.

The computers can process about 8,000 instructions per second - a fraction of the capability of a modern smartphone, which handles upwards of 14 billion each second. With memory measured in kilobytes, the Voyager computers can hold only hold a few thousand words worth of text.

Probably the most intriguing piece of technology onboard Voyager is the legendary ‘Golden Record’ - a phonograph record packaged with a cartridge and needle, operating instructions and loaded with information about Earth.

It contains 115 images of humans, animals and airports, spoken greetings in languages from Akkadian to Chinese, a message from US President Carter and an eclectic 90 minute selection of music.

Carrying such a disc as it travels in silence though the depths of space, Voyager 1 is effectively humanity’s interstellar ‘message in a bottle’ - speeding ever outwards through the ocean of interstellar space towards the edge of forever.

Curiosity on Mars!

An image from NASA's Mars Reconnaissance Orbiter released last week shows NASA's Curiosity Mars rover and the wheel tracks from its landing site to the Glenelg area where the rover worked for the first half of 2013.

The orbiter's High Resolution Imaging Science Experiment (HiRISE) camera captured the scene on 27 June 2013, with the orbiter rolled for an eastward-looking angle rather than straight downward. The afternoon sun illuminated the scene from the western sky, so the lighting was nearly behind the camera. This geometry hides shadows and reveals subtle colour variations.



Curiosity that day was examining an outcrop called Shaler, the rover mission's final science target in the Glenelg area before commencing a many-month trek southwestward to an entry point for the lower layers of Mount Sharp. The rover appears as a bright blue spot in the enhanced colouring of the image.

The image also shows two scour marks at the Bradbury landing site where the Mars Science Laboratory mission's skycrane landing system placed Curiosity onto the ground just about one year ago on 6 August 2012.

The scour marks are where the landing system's rockets cleared away reddish surface dust. Visible tracks commencing at the landing site show the path the rover travelled eastward to Glenelg.

Curiosity may be 140 million miles away on a hostile planet but that’s no excuse for not sending home a self-portrait.

This incredible shot shows Curiosity on the surface back in February - it comprises dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day (or sol) of Curiosity's work on Mars plus three exposures taken during Sol 270 (10 May 2013) to update the appearance of part of the ground beside the rover.


The updated area, which is in the lower left quadrant of the image, shows grey-powder and two holes where Curiosity used its drill on the rock target ‘John Klein’.

The portion has been spliced into a self-portrait that was originally prepared and released in February before the use of the drill. The result shows what the site where the self-portrait was taken looked like by the time the rover was ready to drive away in May 2013.

MAHLI, which took the component images for the mosaic, is mounted on a turret at the end of the rover’s robotic arm and was able to capture the component images with wrist motions and turret rotations. The arm itself was positioned out of the shot in the images, or portions of images, used in the mosaic.

Thanks to the guys at NASA/JPL-Caltech/MSSS for some great photography work!

Dragon's historic test flight

SpaceX is due to begin regular cargo flights to the International Space Station at the end of the summer - and its Dragon spacecraft will be the only craft on the lab's roster of servicing vehicles able to return significant hardware to Earth.

Formal reviews this month after a flawless nine day test flight in May are expected to clear the way for SpaceX's first operational cargo mission sometime in September.

SpaceX's commercial Dragon spaceship made an automated pinpoint splashdown in the Pacific Ocean, completing a feat never before achieved by private industry.


The gumdrop-shaped capsule, blackened by the heat of a high-speed re-entry, splashed down in the Pacific Ocean about 560 miles west of Baja, California, at 1542 GMT.

The Dragon spacecraft became the first privately-owned vehicle to fly to the Space Station, notching that triumph May 25 at the end of a cautious laser-guided approach to the complex.

The capsule also became the first US spacecraft to reach the Space Station since the last Space Shuttle flight departed in July 2011.

With splashdown on 31 May, Dragon proved it could fill a void left after the Shuttle's retirement in returning experiment samples, broken components and other excess hardware to Earth.

The Dragon test flight launched from Florida on May 22 aboard a Falcon 9 rocket. Three days later, after a flyby to demonstrate rendezvous techniques, the spacecraft precisely flew within 30 feet of the Station, close enough for the crew inside the complex to grapple Dragon with a robotic arm.


The astronauts unloaded more than 1,000 pounds of cargo from Dragon's pressurised compartment, including food, clothing, student experiments, and computer gear. The crew installed more than 1,300 pounds of equipment back inside Dragon for return to Earth.

After six days attached to the complex, Dragon was released from the lab's robotic arm at 0935.

SpaceX flight controllers at the company's headquarters in Hawthorne, Calif., commanded the ship's thrusters to five for nearly 10 minutes a few hours later. The thrust slowed Dragon's speed by more than 200 mph, enough for its orbit to drop into the atmosphere for re-entry.

The successful conclusion of the test flight capped a triumphant mission for SpaceX, which intends to outfit the Dragon spacecraft for crewed launches and landings within three or four years. SpaceX is competing for funding from NASA to finance the effort.

Shuttle slips into history

The iconic soul and heart of the US space programme for the past three decades slipped gracefully into history this morning.

Space Shuttle Atlantis swept into the Kennedy Space Center (KSC) making a poignant touchdown on a dark runway just before sunrise at 0557 local time.

Despite the dark pre-dawn skies over Florida large crowds came out to try to glimpse Atlantis as it made its historic return from orbit.

Its de-orbit track brought the orbiter across central Florida and then over Titusville before a hard bank to the left put the vehicle on a line to Runway 15 at KSC.



Touch-down marked a moment of high emotion for the local region - not least because it will trigger a big lay-off of contractor staff. Several thousand involved in Shuttle operations will lose their jobs within days.

Launching people into space is a potent symbol of technological and engineering prowess - but for the Space Shuttle programme it was the pre-dawn landing of Atlantis that truly signalled the end.

"When the wheels stopped on the runway, the displays went blank and the orbiter was unpowered for the final time there was a rush of emotion," said commander Chris ‘Fergie' Fergueson after stepping from the orbiter.

"That was the moment when we all finally realised that it's all over, the crowning jewel of our space programme.

"The Space Shuttle changed the way we view the world and it changed the way we view the Universe."

Big boys don't cry

A delay of a few seconds between a live event and it being broadcast on the TV is normally neither here nor there. But in this case timing was crucial.

For Spaceflight writer Dwayne Day it proved rather more significant, as he explained to me later in the day. He had flown in from Washington and was at Cocoa Beach watching the launch on TV in a friend’s apartment.

The idea was to dash to the outside balcony at the moment the countdown hit zero. As the engines fired on the TV screen he rushed outside, only to see the distant Shuttle already climbing well above the pad!

Watching a Space Shuttle launch is always an emotional experience - but especially so when it is the last one ever in the 30 year history of the programme.

NASA managers at the post-launch media briefing were visibly moved and there was spontaneous and heartfelt applause for the two ‘Mikes’ - Mike Lienbach, Shuttle launch director, and Mike Moses, Shuttle integration manager - as they entered the press room some 90 minutes after liftoff.


When asked about his feelings Mike Moses (left) admitted that he was normally ‘choked’ up after a launch. This time, he said, it was before blastoff.

"It looked like it was lifting off in slow motion," he said. "It was very moving, very beautiful."

After the launch was over we stood around to reflect on the moment. For everyone it was a shared experience. We patted backs and shook hands with friends we had come to know and work with over the years.


For the tightly knit launch team the fun was over too. They lingered in the firing room after the successful launch, exchanging hugs and pats on the back and taking photos together.

"We will never see that again," Mike Leinbach and a colleague remarked to each other. "It was a special moment."

"It seemed like we didn't want to leave," he added. "It was like the end of a party and you just don't want to go."

A jewel of brightness

If there could be a downside to standing near the countdown clock at KSC to witness a launch from the closest point possible - a fraction over three miles - then it is because they no longer broadcast the launch commentary over the PA system.

There are probably good reasons, like the fact that it would upset all the TV companies doing their live broadcasts from the back of the site.

So, we have only the countdown clock as our means of assessing the state of progress and to mark the passage of time towards launch.

When 00:08:59 suddenly appears after the final scheduled ‘hold’ at t-minus nine minutes you know things are getting closer to the grande finale.

There’s excited chatter and people begin shouting out the numbers as the time clicks closer to zero - two minutes and counting, one minute... The excitement and tension is spilling out.

And then we stare in disbelief. Just as it seemed Atlantis had beaten the odds the countdown clock freezes. Cries of dismay - what can have happened at such a late stage? Surely that’s today’s launch attempt over?

Indeed, as the seconds ticked into long minutes some people even started retreating from their spots thinking that it really was all over for today at least.

Out there we had no way of knowing what was happening. No announcements to the assembled crowd - instead of the roar of the mighty engines all remained silent.

Of course, those watching round the world on NASA TV knew that mission control was unsure whether the ‘beanie cap’ that covers the top of the giant orange external tank had properly retracted.

Sounds crazy when you are at the actual launch site but I quickly dialled up home 4000 miles away in England where my wife was glued to NASA’s broadcast.

"It’s a problem with the beanie cap," she quickly explained and then, "but it’s been sorted and they are going!" With that the countdown clock burst to life again, resolutely marking off the last 30 seconds.

Smoke billowed from the pad and at first the Shuttle rose in silence. Then the crackling of its engines comes rumbling across, transforming into a noise that shakes the ground and rocks through your whole body.

Rising majestically one final time, Atlantis spread her wings and powered into the sky with what is understood to have been one million people watching from every available viewpoint in this part of Florida.


The orbiter climbed on a blinding column of fire from the same pad that launched Columbia in 1981 on the very first Shuttle flight, a rippling roar emanating from its main engines and boosters as spectators everywhere cheered, clapped and cried.


The flame was brighter than anything you can manage, almost too piercing to look at in real life - a jewel of brightness climbing into the heavens.


Though it didn't take long for Atlantis to disappear through the clouds, it left a lasting impression for those on the ground.

Even after it reached orbit some eight minutes after liftoff the billowing trail of smoke and steam it left behind maintained a steady link between the launch complex and cloud deck, as if holding on to the last departing Shuttle.


My 'automated' snaps turned out surprisingly well and some of them are added above along with (below) an official NASA shot of the KSC crowd, in which I can be spotted in the foreground if you know exactly where to look.
