Brink: A lot of Debris (5/7)
Space is running out of space. Objects surrounding earth are getting dangerously close to each other.

Two hundred and fifty meters. That’s how close six astronauts aboard the International Space Station (ISS) came today to experiencing a real-life Michael Bay movie. The crew was forced to clamber to their lifeboat just 18 minutes before a piece of space debris narrowly missed colliding with the ISS, reports AFP. “We didn't find out about it in time to perform a debris avoidance maneuver, so we had the crew shelter in place in their Soyuz vehicles," U.S. space agency spokeswoman Stephanie Schierholz told AFP. The incident isn’t the first time there’s been an out-of-this-world close call. Three crewmembers were forced to momentarily evacuate the space station during a March 2009 incident. Only 10 percent of all objects orbiting Earth are satellites. The rest? Trash—5,500 tons of it to be exact. The amount of space litter is set to increase by 5 percent per year. This will only add to the 19,000 “derelict” objects larger than 10 centimeters—spacecraft, rocket stages, and upper-stage rockets and their parts—currently circling our planet, reports NASA’s Orbital Debris Program Office, the U.S. agency that monitors space trash. Space, it turns out, is running out of space. "Everything is spaced out just some 100 meters from each other. One satellite gets in the way of the next. It's way too crowded," said space journalist Vladimir Gubarev to Reuters.
The space debris problem is becoming more and more dire, action must be taken.

The debris problem has become more urgent recently. In February 2009, an American communications satellite collided with a Russian Kosmos satellite, spreading debris around the Earth and prompting concerns about the safety of the finalHubble service mission. In March, 2009, the International Space Station crew spent the morning taking cover in a Soyuz capsule to reduce their cross-section in the event of collision with a space debris object whose track might have intercepted the Space Station. Mutual collisions will continue to increase the debris density until the problem is dealt with
Large amounts of space debris now.

Millions of chunks of metal, plastic and glass are whirling round Earth, the garbage left from 4,600 launches in 54 years of space exploration. The collision risk is low, but the junk travels at such high speed that even a tiny shard can cripple a satellite costing tens of millions of dollars. Around 16,000 objects bigger than 10 centimetres (four inches) across are tracked by the US Space Surveillance Network, according to NASA's specialist newsletter. There are around 500,000 pieces between one and 10 cms (half and four inches), while the total of particles smaller than one centimetre (half an inch) "probably exceeds tens of millions," NASA says elsewhere on its website. The rubbish comes mainly from old satellites and upper stages of rockets whose residual fuel or other fluids explode while they turn in orbit. As the junk bumps and grinds, more debris results. Another big source, though, is a Chinese weather satellite, Fengyun-1C, which China destroyed in a test of an

anti-satellite weapon in 2007. Debris specialists and satellite operators were incensed. At a stroke, it helped increase the tally of large debris by more than a third.
Space debris is continuing to increase with increased space missions.

Millions of new pieces of space junk may have been generated during a Chinese test of an anti-satellite weapon last week, US officials worry. The debris could be dangerous for existing satellites - and even for astronauts aboard the International Space Station and the space shuttle - for years to come. On 11 January, China launched a missile from or near the Xichang Space Centre in the southwestern province of Sichuan. This likely released a projectile that slammed into one of its derelict polar-orbiting weather satellites, known as Feng Yun 1C, which flew at an altitude of about 800 kilometres. The collision created about 40,000 pieces of debris larger than 1 centimetre, estimates David Wright, co-director of the global security programme at the Union of Concerned Scientists in Cambridge, Massachusetts, US. That will nearly double the amount of debris of that size at similar altitudes, he told New Scientist. It may also have created 2 million fragments wider than 1 millimetre across. Such altitudes are heavily trafficked by imaging, meteorological, surveillance, remote-sensing and communications satellites. These spacecraft could be seriously damaged if they were hit by the debris, which can travel at 7.5 kilometres per second - 30 times faster than a jet aircraft. "Small things can cause very big problems," US State Department spokesman Tom Casey said in comments about the Chinese test.
Now is key: the exponential escalation rate of debris means we need to deal with it now.

Incidents like these served as clear signs from above that something must finally be done about space junk. Its proliferation threatens not only current and future space missions but also global communications—mobile phone networks, satellite television, radio broadcasts, weather tracking, and military surveillance, even the dashboard GPS devices that keep us from getting lost. The number of manufactured objects cluttering the sky is now expected to double every few years as large objects weaken and split apart and new collisions create more Kesslerian debris, leading to yet more collisions. NASA’s Bacon puts it bluntly: “The Kessler syndrome is in effect. We’re in a runaway environment, and we won’t be able to use space in the future if we don’t start dealing with this now.”
Now is key – Space debris is a huge problem in the status quo

A scare triggered by orbital debris that on Tuesday came within a couple of hundred metres (yards) of the International Space Station (ISS) sheds light on an acutely worsening problem. Millions of chunks of metal, plastic and glass are whirling round Earth, the garbage left from 4,600 launches in 54 years of space exploration. The collision risk is low, but the junk travels at such high speed that even a tiny shard can cripple a satellite costing tens of
