Italian hospitality

While the politicians of Rome were combusting, if not actually burning, this week, the medieval town of Lucca in the heart of Tuscany was a pretence of calm and polite political dialogue.

In the heart of the walled town, the ornately decorated Palazzo Ducaleis - adorned inside with monumental paintings and wall murals - was the focus for a very different kind of political forum, the Third International Conference on Space Exploration.

Representatives from 28 countries, the European Commission and the European Space Agency (ESA) met for what was described as the first high-level ‘international space exploration platform', which in itself sounds rather like it could be an orbiting satellite.

The organisers shipped in 15 or so journalists from the far reaches of Europe - including Poland, Latvia, Finland and other seemingly unlikely space-faring nations - to help get the message out.

For the rookie space writers among them you could say news was a bit thin on the ground because this wasn't a conference about bold new space projects but more of an attempt to create a new forum where the politics of future space endeavours can be discussed and agreed upon - with the aim of bringing about greater degrees of international cooperation in the future.

Apart from the noticeable absence of anyone from India, all the major space-faring nations - and many who have aspirations in that area but don't really do much at present - were represented at various levels of authority.

Britain's space minister David Willetts, for example, apologised for not being in Lucca in person through his representative Keith Mason.

His opening gambit described the UK as being "well-positioned and very interested" in developing nuclear technology for powering future exploration spacecraft.

Mason also emphasised that lowering the cost of access to Earth orbit was becoming increasingly important.

"We are backing technology to reduce this cost by an order of maginutude," he said, hinting at but not exactly naming the Reaction Engines' Skylon spaceplane project.

"We see exploration as means of stimulating economic advance and developing wider international cooperation, broadening and expanding human horizons."

The conference went on to endorse the ‘Lucca Declaration' and recognise the benefit of a continuing dialogue on future space exploration ‘to help identify potential areas for international cooperation'.

Essentially the government representatives committed to begin open, high-level policy dialogue on space exploration at government-level for the benefit of humankind. The United States offered to host the next get-together in 2013.

China's delegate Jianalin Cao was proud to trumpet recent Chinese successors and highlighted the country's slow but steady progress in taking up the space mantel.

I asked him whether China had aspirations to take its involvement with Europe's long-delayed and woefully over budget Galileo satellite navigation system further?

Speaking through an interpreter - despite his seemingly perfect command of the English language - Cao stated that his country was "starting a new cooperation" with Europe on satellite navigation.

But other than confirming that problems with equipment compatibilities and frequency spectrums were being overcome, little else was forthcoming.

The question of whether China might soon dip into it's pockets and become a major part of Galileo must remain conjecture for the time being.

Tuscan delight

An unexpected turn of events. I find myself on BA’s midday flight from London Heathrow to Pisa, Italy. The Airbus 320 is packed to the rafters and I have to settle for a middle-of-the row seat between two Italian ladies.

Soon we have left the murky British weather of recent days far below and are flying at around 35,000 feet in clear blue skies and sunshine, probably somewhere over Paris.

I’m heading out for a first visit to the medieval Tuscan town of Lucca, one of the most quaint and beautiful towns in this part of Italy, about 30 minutes’ drive from Pisa and maybe an hour from Florence.

As it happens, the Lighthouse Keeper and his then young wife visited Pisa and Florence in the early 1980s. The towns were stopping off points on one of those quite popular (in that decade) 'overland treks' by minibus.

The visit to Pisa was particularly noteworthy because it was in the days before serious ‘health and safety’ rules and regulations had blighted most of Europe and elsewhere.

It meant that, for a few Italian lira, tourists could climb the leaning tower’s ancient stone steps and peer precariously out over the flimsy metal balustrade from very near the top.

Of course, we had no digital cameras or mobile phones in those days to photograph the experience, though somewhere we have faded colour prints and a few precious colour slides as a record of our adventure.

This year’s Tuscan visit to Lucca was prompted by attendance at the grandly titled ‘Third International Space Conference’, thanks to sponsorship of a dozen or so European media people by ESA and the European Commission.

There’s a bit more on the conference to come later but in the meantime here are a selection of photos I managed to shoot whilst getting lost in the streets of Lucca for a couple of hours on a sunny November afternoon.

Journey through space

Spaceflight magazine was first published in 1957 and in all this time there have been only four editors — Patrick Moore, Ken Gatland, Gerald Groves and myself — which must be approaching a record for a magazine with such a long publishing history.

Like the long-running science fiction series Dr Who on BBC TV — where every so often the Doctor regenerates in a new bodily form — it is time for some ‘regeneration’ on Spaceflight. I’ve been at the helm since September 2000 and will be moving on, so this December 2011 (published this weekend) issue is my last as editor.

My association with the British Interplanetary Society (BIS) dates back to the early 1980s when I first became a BIS member, and later started writing occasional articles for Spaceflight.

After working for the marketing departments of two international companies — Perkins Engines in Peterborough and Matra Marconi Space in Portsmouth — for several years I received a phone call in the summer of 2000 to ask if I’d be interested in taking over as editor from Gerald Groves. At the same time I was also running SimComm Europe, a marketing and PR agency founded by myself a few years earlier in south-east Hampshire.

Producing a publication such as Spaceflight every month and maintaining high standards in terms of content and appearance is always a big challenge on a part-time contract — but it has been a privilege to guide and develop the magazine for the past 10 years.

All along the way it has been a great team effort and I have had invaluable support from many people, including a dedicated and expert team of contributors who have all freely given their time — writers, photographers, media and PR people, as well as those with a genuine passion for spaceflight.

It’s not possible to thank everyone but I’d like to acknowledge some of those who have directly supported me with great enthusiasm over the past years and helped enhance Spaceflight’s long-standing reputation.

My sincere thanks to Tim Furniss, Ken Kremer, Gerard van de Haar, Joel Powell, Philip Corneille, Dwayne Day, Ralph Gibson, Ed Hengeveld, Rudolf van Beest, Jacques van Oene, Kelvin Long, Andrew Green, Nick Spall, Rob Coppinger, Tony Quine, George Spiteri, Geoff Richards, Francis French, David A Hardy, Michael Cockerham, Mark Williamson, Lucy Owens (my invaluable deputy editor between 2001 and 2004), and BIS staff Suszann Parry, Mary Todd and Ben Jones, along with Society President Bob Parkinson for allowing that valuable commodity ‘editorial freedom’, and of course to my family for their love and support.

As for the future, the Spaceflight editorial chair ‘regenerates’ forthwith and passes to David Baker, who has a life-long passion for astronautics and the exploration of worlds beyond our own.

It’s funny how things go in circles. I first met David when I was a student and he was lecturing on space exploration in South Lincolnshire. In fact, it was he who introduced me to the BIS. Perhaps there is something in this Dr Who time travel business after all?

Sunshine in Rutland

We can’t consign the balmy month of October 2011 to history without noting that in the UK temperatures soared, reaching a new record high for the month of 29.9 C.

The top temperature was recorded on the first day of the month in Swanscombe, Kent, which basked in 165 hours of sunshine this month, an average of more than five a day. The previous hottest October day was 29.4 C, recorded in Cambridgeshire in 1985.

Although the temperatures dropped back somewhat in the following days, overall Britain enjoyed its warmest October for five years and its seventh warmest since records began.

The balmy autumn was relatively dry too, with average rainfall of 64 mm for the month and less than 20 mm in the East Midlands, East Anglia and the north Home Counties. This made it drier than three out of four of the last 100 Octobers.

It was sunnier than three-quarters of all Octobers in the last 100 years, with an average of 123 hours of sunshine for England and Wales, and 69 hours for Scotland.

The month almost ended as it started too as October seemed intent on signing off on a high note. It was a pleasant surprise to enjoy a picture-prefect day on 28 October - the last day of school half-term week - with warm sunshine and a deep blue sky.


A day trip to Rutland Water, a man-made reservoir in the east of England, was all the more special for the fine weather, with the opportunity to picnic outside and bask in the bright sunlight.

As these pictures show, however, much of East Anglia is still in drought conditions. The reservoir’s water level is well below where Anglian Water would like it to be.



Rutland Water, set in 4200 acres of open countryside, is Anglian Water's drinking water reservoir in the county of Rutland, England, just east of the county town Oakham. It was known as Empingham Reservoir during its construction and until its official opening in 1976.

It provides a reserve supply of water in the driest and most densely populated quarter of the United Kingdom and is one of the largest artificial lakes in Europe. By surface area it is the largest reservoir in England, though by capacity it is exceeded by Kielder Water in Northumberland.

Let there be light


The Milky Way strode across the sky, a band of faint light spanning almost from horizon to horizon. In the distance, lights sparkled like ships on a dark ocean. Such a dark sky with a myriad twinkling stars is a sight that is becoming all too rare - or even beyond the experience of many.

This is the heart of the Fens at night. A natural planetarium with glorious low horizons in every direction and a pitch dark sky, just far enough from the sodium city lights of Peterborough and the market towns of Stamford and Spalding.

Indeed, this part of South Lincolnshire, an industrial farming and food-producing landscape by day, is by night one of Britain’s dwindling exceptions to our light-polluted lives.

According to the Council for the Protection of Rural England (CPRE), places with the ‘purest’ night-time darkness are (perhaps by definition) among the least populated in the country.

Dartmoor, Exmoor and the Quantock Hills in the south west; Salisbury Plain and the top of the Chilterns in southern England; parts of Lincolnshire to the east; the Black Mountains and the Brecons in Wales; the Yorkshire moors and some of Northumberland; plus large swathes of Scotland, outside major cities and the Borders.

Early this year Sark – the smallest of the four Channel Islands at just a couple of square miles – became the world's first officially-designated ‘Dark Sky Island’.


The US-based International Dark-Sky Association measured Sark's night-time illumination levels and assessed the degree of visibility of constellations in the night sky. And to assist Sark's claim, one of its government officers visited every outside light on the island and recommended measures to cut artificial light seeping into the sky.

Sark is not Britain's only dark success. In 2009 Galloway Forest in Scotland was designated Europe's first ‘Dark Sky Park’. As a result visitor numbers are booming, a new observatory is planned for the edge of the forest and neighbouring local councils have introduced restrictions on outside lighting to preserve the quality of darkness.

The Inner Hebrides’ island of Coll, 13 miles long and three miles wide with two main roads and a small airport, is another dark spot with no security lights on homes, or traffic or street lights.

Much closer to home, the Rutland village of Market Overton recently reduced its light pollution by replacing its old sodium street lights with modern light-emitting diode lamps. Its 39 lamps cost over £20,000 in total to convert but immediately produced an 80 per cent saving in electricity.

These locations, however, remain the exceptions to the light-polluted rule. And they are getting rarer thanks to what the Campaign for Dark Skies describes as ‘wasteful’ over-provision of domestic lighting by British householders.

CPRE has, for several years, urged government action to limit light pollution from street lamps, overnight illumination of shopping centres, office blocks and public buildings, stark upward lighting from floodlit sports complexes and, at the household level, outdoor lights that are unnecessarily bright or disperse their illumination. Of course it would also save a lot of money and energy too – Britain's street lamps alone cost an estimated £500 million a year to run.

The most common forms of such pollution are ‘light trespass’ when illumination from Britain's 22 million homes and 7.5 million street lights, even if designed with the intention of shining downwards, typically also extends upwards. You can see it in this picture of the UK at night as seen by astronauts passing overhead aboard the International Space Station.


Two other common forms are ‘sky glow’ – that orange glow visible for tens of miles around towns and cities easily seen from the air or from distant roads – and ‘glare’, the harsh white light on some modern housing estates and golf driving ranges at night.

As October marches onwards, here in the northern hemisphere we are plunging headlong into days of less daylight, longer nights and the clocks going back – all marking the onset of winter. And, while we say we prefer it lighter for longer, in reality most of us only now experience a limited degree of darkness.

Modern electricity's triumph over the night keeps us all busier. We live in a fast-moving, fully lit world where night still happens but is more of an optional experience – a kind of failed daylight. Our 24/7 supermarket culture has done it’s best to phase out the night.

Yet slowness and silence – the different rhythm of the night – are a necessary correction to the day. Life is too short to be all daylight. Moments of life take on a different quality at night-time, where the moon reflects the light of the sun and we have time to reflect what life is to us. So why not turn down the lights and rest awhile? Night is not less – it's more.

How high is Everest?

In an effort to put an end to generations of controversy, the authorities in Nepal are trying to ascertain the precise height of the world's biggest mountain. The project could take up to two years - and even then it is more than likely that not everyone will agree.

While for well over 100 years Everest has been recognised as the planet's highest point, there are differences of opinion as to the exact dimensions and even over what should actually be measured.

For more than half a century, Nepal has recognised the generally accepted height of 29,028 ft for the mountain they call Sagarmatha - despite the insistence by neighbouring China that what it refers to in Tibetan as Qomolangma (Holy Mother), is actually 29,017 ft. The mountain straddles the border and neither side wishes to back down.

"We have begun the measurement to clear this confusion," Gopal Giri, a spokesman with Nepal's land management ministry. "Now we have the technology and the resources we can measure ourselves. This will be the first time the Nepal government has taken the mountain's height."

The task of measuring the height of the world’s highest mountain was first performed during the days of British rule in the subcontinent by a Bengali mathematician, Radhanath Sikdar, employed in the office of the surveyor general, Sir Andrew Waugh.

At the time the British authorities were conducting the so-called Great Trigonometric Survey and it was believed that Kangchenjunga in Sikkim was the world's highest. But based on data collected from the field, Sikdar concluded in 1854 that another nearby peak, at the time referred to simply as Summit XV, was higher.

For two years, the team reassessed the findings and then, confident of what they had discovered a new giant, announced their news. Several years later, in 1865, Sir Andrew declared that the peak would be known as Mount Everest, in honour of his predecessor, Sir George Everest. Based on the average figure obtained from six separate surveying stations, each 100 miles from the mountain, it was said to have a height of 29,002 ft.

This height remained in accepted use for the best part of a century, including in 1953 when Edmund Hilary and Norgay Tenzing made their way to the summit and safely descended.

The following year, a survey by the Indian authorities suggested a new height for the mountain, of 29,028 ft, based on the average reading for 12 survey stations, located between 30 and 50 miles from Everest. But the availability of new technology in the subsequent years led new teams to question the estimate. In 1992 a joint Chinese and Italian expedition team was the first to use GPS technology and came up with a figure of 29,031 ft.

In 1999, a team led by the late American mountaineer Bradford Washburn spent several years working with GPS devices to make a new calculation. Washburn's climbers were able to reach the summit and use their measuring devices.

Not only did they come up with a new height, 29,035.3 ft, but they said they had also been able to measure the movement of the Everest massif, being pushed by the Eurasian continental shelf. They estimated that the mountain was moving north-east by around a quarter of an inch a year.

There the matter may have ended, but for the wishes of the Chinese to take yet another measurement. In 2005, a team of mountaineers and researchers climbed Everest from the Chinese side and announced a new reading of 29,017 ft. However, they said this only measured the actual rock formation of Everest and not the snow cap on the very top.

Nepali officials complained that during discussions about the border with their much larger neighbour, China insisted on using its own measure. But last year, the two countries agreed that both measurements might be correct.

"Both are correct heights. No measurement is absolute. This is a problem of scientific research," Raja Ram Chhatkuli, director general of Nepal's survey department, said at the time.

Mr Chhatkuli will be overseeing Nepal's own attempt at a precise assessment in which scientists will place three GPS devices on different locations on the mountain from which to obtain data.

If you are a regular reader you may be asking, why the sudden interest in Everest by the Lighthouse Keeper on a blog that has previously made its name largely covering the final two missions of the US Space Shuttle?

Well, the Lighthouse Keeper hasn’t made it any where near the top of this mighty mountain - but this autumn is the tenth anniversary of my first visit to Nepal and a high-level trek through the Everest region.

That was in the days before blogs so, come next month, the Lighthouse Keeper will be putting things right and embarking on the trip all over again - this time from the relative comforts of home.

A kind of day-by-day blog retrospective reliving the journey in words and pictures - from the excitement and heat of Kathmandu to the extreme cold and wilds of the lower reaches of Everest. Stay tuned for a great upcoming adventure!

Pictures from above

As a keen photographer the Lighthouse Keeper is always looking for a new angle or perspective on a familiar subject - but from an earthly vantage point even perched atop of a high crane is no match for the kind of views astronauts have from the orbiting International Space Station.

This night time view of India-Pakistan borderlands was one of a series of night-time shots captured recently by one of the six crew members, who often say that one of their favourite off-duty pastimes is gazing back at Earth as there is "always something spectacular to see".


Clusters of yellow lights on the Indo-Gangetic Plain of northern India and northern Pakistan reveal numerous cities both large and small.

Of the hundreds of clusters, the largest are the metropolitan areas associated with the capital cities of Islamabad, Pakistan, in the foreground and New Delhi, India, at the top. For scale these metropolitan areas are approximately 700 km apart.

The lines of major highways connecting the larger cities also stand out. More subtle but still visible at night are the general outlines of the towering and partly cloud-covered Himalayan ranges immediately to the north (left).

A striking feature of this photograph is the line of lights, with a distinctly more orange hue, snaking across the central part of the image.


It appears to be more continuous and brighter than most highways in the view and is actually the fenced and floodlit border zone between the countries of India and Pakistan. The fence is designed to discourage smuggling and arms trafficking between the two countries.

This image was taken on a digital SLR camera with a 16 mm lens to provide a wide field of view, as the Space Station was tracking towards the southeast across the subcontinent of India.

The distinct, bright zone above the horizon (visible at top) is produced by airglow, a phenomena caused by excitation of atoms and molecules high in the atmosphere (above 80 km altitude) by ultraviolet radiation from the Sun. Part of the ISS and a solar panel array are visible at right.

This photograph below, taken from the Space Station at the end of July 2011, shows the Moon with the limb of Earth near the bottom, transitioning into the orange-coloured troposphere, the lowest and most dense portion of Earth's atmosphere.

The troposphere ends abruptly at the tropopause, which appears in the image as the sharp boundary between the orange and blue-coloured atmosphere. The silvery-blue noctilucent clouds extend far above the Earth's troposphere.
