Will space mining become a reality?

Planetary Resources to Soviet meteor diamonds and beyond.

As US presidential candidates drum up support in their race for the White House, scientists are also working against the clock to get space mining on the agenda before the 2014 budget plan takes off.

This month, four entrepreneurs made their pitches at the American Institute of Aeronautics and Astronautics Space 2012 conference, Clint Eastwood-style.

Neither Barack Obama nor Mitt Romney attended the event, so space panelists addressed two empty chairs with their ideas, paying tribute to Eastwood’s "invisible Obama" act at the Republican national convention. The delegates poked fun at the candidates but were deadly serious about space-age ideas.

The buzz really started in April, with the arrival of Planetary Resources (PR) – a new venture made up of the Nasa scientists Chris Lewicki and Tom Jones and the space entrepreneurs Peter Diamandis and Eric Anderson – which hopes to mine near-earth asteroids within ten years.

PR’s timing couldn’t be better. Not since the early space missions have "interplanetary exploration", "asteroids" and all things Martian been household buzzwords. It's all thanks to Nasa’s Mars rover Curiosity, which, as I write, is unlocking the geological secrets of a pyramid-shaped rock named Jake Matijevic.

As if this wasn’t exciting enough, the world was recently given a glimpse of the treasure troves we could find orbiting in space and right here on earth.

Russia recently revealed that the crater of a meteorite that landed in Siberia 35 million years ago, contains trillions of carats of rare diamonds. The Soviet government discovered the deposit in 1970s but it’s only now that documents have been disclosed revealing the true extent of the diamond hoard, which scientists say could supply the entire world for 3,000 years.

The growing interest in space mining is understandable. Based on known reserves on earth and growing consumption in developing countries, it is estimated that key elements such as gold and platinum, essential for modern industries, could be exhausted within 60 years. Yet with analysts claiming that mining in space is not economically feasible, are the scientists' ideas a little starry-eyed?

Due to Nasa’s tightening budget, just $800m is currently available to bring rock samples from Mars back to earth, not a substantial amount considering an upcoming mission to return just two ounces of material from an asteroid will cost $1bn.

As for PR, this company has the financial backing of the Google billionaires Eric Schmidt and Larry Page but how much of a profit can be made from mining platinum and gold, valued at about $1,600 an ounce, when logistical costs are so high?

The 100km Popigai meteorite crater found in Siberia is said to contain diamonds that are two times harder than regular ones but these resources can only be used for industrial use, not jewellery. Currently, the cost of mining far outweighs the asking price for industrial diamonds and profits can only be made from selling gemstone diamonds. The market already has a more easily accessible substitute for this material: lab-grown industrial diamonds.

The world, it seems, is stuck in a catch-22 situation – it needs money to fund mining and it need mining to make money. The question is, should scientists, entrepreneurs and governments wait until earth’s reserves run out or take a giant leap of faith?

Who really controls the Labour Party now?

Jeremy Corbyn's allies will struggle to achieve their ambition to remove general secretary Iain McNicol.

Jeremy Corbyn's advance at the general election confirmed his place as Labour leader. Past opponents recognise not only that Corbyn could not be defeated but that he should not be.

They set him the test of winning more seats – and he passed. From a position of strength, Corbyn was able to reward loyalists, rather than critics, in his shadow cabinet reshuffle. 

But what of his wider control over the party? Corbyn allies have restated their long-held ambition to remove Labour general secretary Iain McNicol, and to undermine Tom Watson by creating a new post of female deputy leader (Watson lost the honorific title of "party chair" in the reshuffle, which was awarded to Corbyn ally Ian Lavery).

The departure of McNicol, who was accused of seeking to keep Corbyn off the ballot during the 2016 leadership challenge, would pave the way for the removal of other senior staff at Labour HQ (which has long had an acrimonious relationship with the leader's office). 

These ambitions are likely to remain just that. But Labour figures emphasise that McNicol will remain general secretary as long he retains the support of the GMB union (of which he is a former political officer) and that no staff members can be removed without his approval.

On the party's ruling National Executive Committee, non-Corbynites retain a majority of two, which will grow to three when Unite loses a seat to Unison (now Labour's biggest affiliate). As before, this will continue to act as a barrier to potential rule changes.

The so-called "McDonnell amendment", which would reduce the threshold for Labour leadership nominations from 15 per cent of MPs to 5 per cent, is still due to be tabled at this year's party conference, but is not expected to pass. After the election result, however, Corbyn allies are confident that a left successor would be able to make the ballot under the existing rules. 

But Labour's gains (which surprised even those close to the leader) have reduced the urgency to identify an heir. The instability of Theresa May's government means that the party is on a permanent campaign footing (Corbyn himself expects another election this year). For now, Tory disunity will act as a force for Labour unity.
