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.

PMQs review: Jeremy Corbyn prompts Tory outrage as he blames Grenfell Tower fire on austerity

To Conservative cries of "shame on you!", the Labour leader warned that "we all pay a price in public safety" for spending cuts.

A fortnight after the Grenfell Tower fire erupted, the tragedy continues to cast a shadow over British politics. Rather than probing Theresa May on the DUP deal, Jeremy Corbyn asked a series of forensic questions on the incident, in which at least 79 people are confirmed to have died.

In the first PMQs of the new parliament, May revealed that the number of buildings that had failed fire safety tests had risen to 120 (a 100 per cent failure rate) and that the cladding used on Grenfell Tower was "non-compliant" with building regulations (Corbyn had asked whether it was "legal").

After several factual questions, the Labour leader rose to his political argument. To cries of "shame on you!" from Tory MPs, he warned that local authority cuts of 40 per cent meant "we all pay a price in public safety". Corbyn added: “What the tragedy of Grenfell Tower has exposed is the disastrous effects of austerity. The disregard for working-class communities, the terrible consequences of deregulation and cutting corners." Corbyn noted that 11,000 firefighters had been cut and that the public sector pay cap (which Labour has tabled a Queen's Speech amendment against) was hindering recruitment. "This disaster must be a wake-up call," he concluded.

But May, who fared better than many expected, had a ready retort. "The cladding of tower blocks did not start under this government, it did not start under the previous coalition governments, the cladding of tower blocks began under the Blair government," she said. “In 2005 it was a Labour government that introduced the regulatory reform fire safety order which changed the requirements to inspect a building on fire safety from the local fire authority to a 'responsible person'." In this regard, however, Corbyn's lack of frontbench experience is a virtue – no action by the last Labour government can be pinned on him. 

Whether or not the Conservatives accept the link between Grenfell and austerity, their reluctance to defend continued cuts shows an awareness of how politically vulnerable they have become (No10 has announced that the public sector pay cap is under review).

Though Tory MP Philip Davies accused May of having an "aversion" to policies "that might be popular with the public" (he demanded the abolition of the 0.7 per cent foreign aid target), there was little dissent from the backbenches – reflecting the new consensus that the Prime Minister is safe (in the absence of an attractive alternative).

And May, whose jokes sometimes fall painfully flat, was able to accuse Corbyn of saying "one thing to the many and another thing to the few" in reference to his alleged Trident comments to Glastonbury festival founder Michael Eavis. But the Labour leader, no longer looking fearfully over his shoulder, displayed his increased authority today. Though the Conservatives may jeer him, the lingering fear in Tory minds is that they and the country are on divergent paths.
