Does the Earth need a space fence?

Being hit by space junk is rubbish.

Last week, NASA confirmed that the International Space Station may have to be moved or risk being hit by a sizeable lump of Russian space junk. With hundreds of thousands of pieces of debris littering the atmosphere, has our desire for space exploration inadvertently created a volatile and hazardous junkyard?

The danger was posed by defunct Russian military satellite Kosmos 2251, infamous for colliding with US satellite Iridium-33 in February 2009. The incident sent hundreds of pieces of debris spiralling out of control in Earth’s atmospheric orbit, adding to the debris currently tracked by the US Air Force.

Of course, this is an issue entirely of our own doing. Years of launching satellites without an afterthought for the abandoned rocket components have left Earth’s geostationary orbit more congested than the M25 on a Friday evening.

There is, however, a solution. Short of erecting a series of 2,000km-high concrete posts and wooden panels, NASA hopes to track objects orbiting the planet using what it has called the "Space Fence". Three radar sites, with one already chosen to be located on Kwajalein Island, part of the Republic of the Marshall Islands, will help the administration track up to 200,000 pieces of debris simultaneously.

The US military’s current equivalent, the Space Surveillance Network, tracks a catalogue of 15,000-20,000 identified pieces of debris, ensuring that operators of satellites and installations are warned of potential collisions. With a burgeoning number of nations now edging towards becoming space-able this catalogue needs to be expanded, and Space Fence offers to do just that.

Not only will objects be tracked and future collisions reconstructed, but the system’s processing power will be capable of determining the best possible launch window for satellites and shuttles. Space Fence will essentially act as NASA’s very own traffic management system.

At an expected cost of $6.1bn, Space Fence represents the single largest investment from the US Air Force in Space Situational Awareness, and what is likely to become one of the most expensive clean-up jobs in history.

Sadiq Khan likely to be most popular Labour leader, YouGov finds

The Mayor of London was unusual in being both well-known, and not hated. 

Sadiq Khan is the Labour politician most likely to be popular as a party leader, a YouGov survey has suggested.

The pollsters looked at prominent Labour politicians and asked the public about two factors - their awareness of the individual, and how much they liked them. 

For most Labour politicians, being well-known also correlated with being disliked. A full 94 per cent of respondents had heard of Jeremy Corbyn, the current Labour leader. But when those who liked him were balanced out against those who did, his net likeability rating was -40, the lowest of any of the Labour cohort. 

By contast, the Labour backbencher and former army man Dan Jarvis was the most popular, with a net likeability rating of -1. But he also was one of the least well-known.

Just four politicians managed to straddle the sweet spot of being less disliked and more well-known. These included former Labour leadership contestants Yvette Cooper, Andy Burnham, and Hilary Benn. 

But the man who beat them all was Sadiq Khan, the Mayor of Lodon. 

YouGov's Chris Curtis said that in terms of likeability Khan "outstrips almost everyone else". But since Khan only took up his post last year, he is unlikely to be able to run in an imminent Labour contest.

For this reason, Curtis suggested that party members unhappy with the status quo would be better rallying around one of the lesser known MPs, such as Lisa Nandy, Jarvis or the shadow Brexit minister Keir Starmer. 

He said: "Being largely unknown may also give them the opportunity to shape their own image and give them more space to rejuvenate the Labour brand."

Another lesser-known MP hovering just behind this cohort in the likeability scores is Clive Lewis, a former journalist and army reservist, who served in Afghanistan. 

Lewis, along with Nandy, has supported the idea of a progressive alliance between Labour and other opposition parties, but alienated Labour's more Eurosceptic wing when he quit the frontbench over the Article 50 vote.

There is nevertheless space for a wildcard. The YouGov rating system rewards those who manage to achieve the greatest support and least antagonism, rather than divisive politicians who might nevertheless command deep support.

Chuku Umunna, for example, is liked by a larger share of respondents than Jarvis, but is also disliked by a significant group of respondents. 

However, any aspiring Labour leader should heed this warning - after Corbyn, the most unpopular Labour politician was the former leader, Ed Miliband. 

Who are YouGov's future Labour leaders?

Dan Jarvis

Jarvis, a former paratrooper who lost his wife to cancer, is a Westminster favourite but less known to the wider world. As MP for Barnsley Central he has been warning about the threat of Ukip for some time, and called Labour's ambiguous immigration policy "toxic". 

Lisa Nandy

Nandy, the MP for Wigan, has been whispered as a possible successor, but did not stand in the 2015 Labour leadership election. (She did joke to the New Statesman "see if I pull out a secret plan in a few years' time"). Like Lewis, Nandy has written in favour of a progressive alliance. On immigration, she has stressed the solidarity between different groups on low wages, a position that might placate the pro-immigration membership. 

Keir Starmer

As shadow Brexit minister and a former director of public prosecutions, Starmer is a widely-respected policy heavyweight. He joined the mass resignation after Brexit, but rejoined the shadow cabinet and has been praised for his clarity of thought. As the MP for Holborn and St Pancras, though, he must fight charges of being a "metropolitan elite".
