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.

Bertie Carvel's diary: What would the French think about infidelity to Doctor Foster?

The joy of debuting a new series, Rupert Murdoch's squeamishness and a sting in the tail.

According to the adage, the first thing an actor does when he gets a job is to go on holiday. And so, having finished our sold-out run of James Graham’s Ink at the Almeida and with the show (in which I play a young Rupert Murdoch) about to transfer into the West End, I’m packing my bags.

But before I can skip town, I’ve one more professional engagement: the press launch of series two of the BBC drama Doctor Foster, which we finished filming at Christmas. I’ve now seen the final cut of all five episodes, and I’m excited to share it with an audience. There’s no substitute for seeing other people’s reactions at first hand, especially with a show that got people talking so much first time around, and it’s electric to sit in a cinema full of expectant journalists and commentators and feel the room respond. Nothing beats this: to put so much into making a thing and then experience an audience’s unmediated, reflexive reaction. When it goes well, you feel that you’ve shared something, that you’ve all recognised something together about how things are. It’s a unifying feeling. A sort of bond.

Cheating spouses

Handling the interviews has been tricky, when there’s so little one can say without giving the plot away. (The first series began with Suranne Jones’s character Gemma, a GP, suspecting her husband Simon of having an affair.) What’s more, lots of the questions invite moral judgements that I’ve tried my best to avoid; I always think it’s really important not to judge the characters I play from outside, but simply to work out how they feel about themselves, to zero in on their point of view. There’s a sort of moral bloodlust around this show: it’s extraordinary. People seem to want to hear that I’ve been pilloried in the street, or expect me to put distance between myself and my character, to hang him out to dry as a pariah.

While I’m not in the business of defending Simon Foster any more than I’m in the business of attacking him, I am intrigued by this queer mixture of sensationalism and prurience that seems to surface again and again.

Shock horror

Oddly enough, it’s something that comes up in Ink: many people have been surprised to find that, in a story about the re-launch of the Sun newspaper in 1969 as a buccaneering tabloid, it’s the proprietor who considers dropping anchor when the spirit of free enterprise threatens to set his moral compass spinning.

I’ve never given it much thought before, but I suppose that sensationalism relies on a fairly rigid worldview for its oxygen – the SHOCKERS! that scream at us in tabloid headlines are deviations from a conventional idea of the norm. But what’s behind the appetite for this sort of story? Do we tell tales of transgression to reinforce our collective boundaries or to challenge them?

For me there’s a close kinship between good journalism and good drama. I’m reminded of the words of John Galsworthy, who wrote Strife, the play I directed last summer, and who felt that the writer should aim “to set before the public no cut-and-dried codes, but the phenomena of life and character, selected and combined, but not distorted, by the dramatist’s outlook, set down without fear, favour, or prejudice, leaving the public to draw such poor moral as nature may afford”.

So when it comes to promoting the thing we’ve made, I’m faced with a real conundrum: on the one hand I want it to reach a wide audience, and I’m flattered that there’s an appetite to hear about my contribution to the process of making it; but on the other hand I think the really interesting thing about the work is contained in the work itself. I’m always struck, in art galleries, by how much more time people spend reading the notes next to the paintings than looking at the paintings themselves. I’m sure that’s the wrong way around.

Insouciant remake

En route to the airport the next morning I read that Doctor Foster is to be adapted into a new French version. It’s a cliché verging on racism, but I can’t help wondering whether the French will have a different attitude to a story about marital infidelity, and whether the tone of the press coverage will differ. I wonder, too, whether, in the home of Roland Barthes, there is as much space given to artists to talk about what they’ve made – in his 1967 essay, “The Death of the Author”, Barthes wrote that “a text’s unity lies not in its origin but in its destination”.

No stone unturned

Touring the villages of Gigondas, Sablet and Séguret later that evening, I’m struck by the provision of espaces culturels in seemingly every commune, however small. The French certainly give space to the work itself. But I also notice a sign warning of a chat lunatique, so decide to beat a hasty retreat. Arriving at the house where I’m staying, I’ve been told that the key will be under a flowerpot. Lifting each tub in turn, and finally a large flat stone by the door, I find a small scorpion, but no key. I’m writing this at a table less than a yard away so let’s hope there won’t be a sting in this tale.

Ink opens at the Duke of York Theatre, London, on 9 September. More details: almeida.co.uk
