Why was the satellite a danger to the space station?
The answer lies in the engineering: Most modern electric propulsion satellites have Hall Effect Thrusters, which use high-pressure propellant tanks. And, when punctured by a high-velocity object (like a Russian missile), they explode, launching thousands of fragments in every direction.
What does the Chinese satellite Feng Yun 1C have to do with the problem of space debris?
…the Chinese military destroyed the Fengyun-1C weather satellite in a test of an antisatellite system, creating more than 3,000 fragments, or more than 20 percent of all space debris.
What causes satellites to fail?
An orbit is the perfect balance between a satellite’s forward momentum or inertia and the pull of gravity on it. If either of these are changed, the orbit will fail, and the satellite will either crash down onto the object it is orbiting or spin off into space.
Is space debris a problem?
While space debris is unlikely to affect space travel, it will lead to significant problems for spaceflight around Earth. The risk would be highest for objects orbiting at an altitude of around 1,000 kilometres (620 miles), which is used for communications and Earth observation.
Has space junk ever hit the ISS?
Last week, the International Space Station (ISS) was forced to maneuver out of the way of a potential collision with space junk. In May this year there was a hit: a tiny piece of space junk punched a 5mm hole in the ISS’s Canadian-built robot arm.
Is the space station damaged?
The International Space Station has been hit by fast-moving debris — but it didn’t cause too much damage. Space junk hurtling towards the station smashed into one of its robotic arms, leaving a hole. NASA and the Canadian Space Agency first noticed the damage on Canadarm2 on May 12, according to a recent statement.
What are the problems of space debris?
The rising number of space debris increases the potential danger to all space vehicles, especially to ones with humans aboard, the International Space Station (ISS), for instance. A number of space shuttle windows have been replaced because of damage caused by paint flecks.
