Did we fly to the Moon too soon?

UNBELIEVABLY it has been almost a half century since Neil Armstrong and Buzz Aldrin bounced across the lunar landscape for the first time.

Certainly, in terms of human exploration, project Apollo was perceived as a stepping stone to greater things rather than marking a pinnacle of human achievement.       

But the sudden cancellation of the final three missions - despite the fact that the hardware for each had already been built - ably illustrates the financial and political difficulties of sustaining space exploration. Apollo 20 was shelved in January 1970. Eight months later, Apollo 18 and Apollo 19 were also cancelled, making Apollo 17, all the way back in December 1972, the final and most recent human mission to the Moon.

Five decades on and the United States, Europe, Russia, China, Japan and India, along with a handful of private entrepreneurs and firms, all harbour new lunar exploration ambitions.

In October 2017, US Vice-President Mike Pence announced a significant re-direction for NASA - a new road map to create a sustained human presence on the M oon’s surface. It’s a big change for the agency which, for the past decade, has been heading, somewhat tentatively, for a future of deep space exploration and taking humans to Mars.

But words are not enough and to become reality ambitious programmes require ambitious sums of money, along with sustained long-term political commitment.           

Fortunately, NASA’s rapidly maturing new hardware for deep space missions can also be easily re-purposed to take us back to the Moon.

Its giant rocket - known prosaically as the ‘Space Launch System’ (SLS) - and a crew capsule called Orion designed to carry people into deep space, can easily become the mainstay of future lunar missions.               

A so-called cislunar architecture and an associated economy that supports or is part of a return to the Moon offers many opportunities.

Fresh political direction and some of the essential hardware may almost be in place but establishing a sustained presence on the Moon is also going to require the creation of a lunar lander, habitats, life support systems and more.

Long-term funding (at one point, NASA estimated a return to the Moon would cost upwards of US $100 billion) and time (particularly in a political context) are rare commodities in our modern world.

To succeed, space exploration projects still need to be challenging and inspirational, perhaps with a nod towards commercialism.

They must also cover the bases of meaningful international partnerships and private sector
participation, and include the less glamorous aspects of building components, delivering cargo and providing ‘multi-layered’ services.   

Today, the nature of leadership in space is very different to the politically driven aspirations of the 1960s and 1970s. Back then it was more about doing things that no other country could do - and being there first.

Ten years after Apollo 11, the science writer and science fiction author Arthur C Clarke suggested that space travel might be “a technological mutation that should not really have arrived until the 21st century”.

If mankind was not really ready to go to the Moon in the late 1960s and the early 1970s then perhaps now is exactly the right time.

Moon rover awakes

China's lunar rover - the first spacecraft to land on our nearest planetary neighbour in 37 years - has awoken after its troubled dormancy.

But scientists are still trying to find out the cause of a mechanical control abnormality that occurred as the craft went into a scheduled two-week hibernation period during the lunar ‘night’.

After several days of uncertainty Pei Zhaoyu, a spokesman for the Chinese space programme, announced this morning that the country’s moon rover had been restored to its normal signal reception function.

The problem emerged on 25 January before Yutu (Jade Rabbit) entered its second period of planned dormancy on the moon as lunar night fell.

"Yutu went to sleep under an abnormal status," Pei said, adding that experts were concerned that it might not be able to survive the extremely low temperatures during the lunar night.

"The rover stands a chance of being saved now that it is still alive," he said.

Its deployment on 15 December 2014 was the first successful landing on the Moon since 1976 and it was expected to operate for about three months.

Earlier reports in Chinese media had suggested that it had been declared dead on the surface of the moon.

In a report entitled ‘Loss of lunar rover’, the China News Service said that the rover "could not be restored to full function on Monday as expected" and was "mourned" by Chinese social media users.

The six-wheeled rover is designed to hibernate during the lunar night, when the sun dips below the horizon for two weeks and temperatures plunge to minus 180C (-292F).

The rover carries plutonium heaters to keep the rover's delicate electronics warm at night and is fitted with solar panels to generate power for the vehicle's science instrumentation, radio transmitters and other equipment. 

Before the sun goes down at Yutu's landing site, it is programmed to fold down its camera, antenna mast and solar panels. It is while executing these the rover ran into trouble 

Unofficial accounts posted on Chinese websites claimed it was unable to stow one of its solar panels over the retracted camera mast on top of the robot's instrument deck.

The Chang'e 3 lander and its rover (see Sleeping satellite) marked a milestone in China's ambitious long-term space exploration programme, which includes establishing a permanent space station in Earth orbit.

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.
