What countries contribute to space junk the most?
The number one contributor to space junk is Russia and the UK.
Does space junk interact with asteroids?
This would happen, space junk could collide with asteroids, but most space junk is close to the earth, away from the main asteroid belt. It would be more likely to collide with meteroids and other bits of space junk.
What is the system to get satellites back to earth?
There is none, we let them fall. Thousands of pieces of manmade space-junk fall back to earth every year, not one piece has ever harmed a human being. The earth is big, we are small, and most importantly, most of the junk burns up in the atmo : D
What are the most common things found in a junk drawer?
Owner manuel
What occurs the most in space?
Nothing. That is the most common feature of outer space.
What happens to the junk thrown by astronomers in the space station and space shuttles Does it stay afloat?
It usually stays in orbit around the earth, and poses a serious threat to all orbiting satellites. Even a small object can destroy things at high speed. Most satellites can move around projected paths of junk thrown in space. Some astronomers use radio telescopes to track "Space Junk".
What is the effect of space junk now and in the future?
Space junk, in others words is trash floating around our Earth caught in a circular orbit. Space junk has caused problems and I will happily list a few for the answer. For one, if it is biggest enough sometimes it will fall back to the Earth and unlike most things, not burn up in the atmosphere and come crashing to Earth which itself poses dangers. Another is moving space junk can become problems to space stations. Damage, severe or little can be caused by junk ramming into the station. More problems it poses by space shuttles can, sometimes, hit space junk which you can figure is a problem. More or less Space Junk in other words is pollution in space.
Does space junk float in space?
In a sense. In space, technically no object floats, but rather is in continuous free fall. Contrary to popular belief there is gravity in space; it is the may force acting on objects. Most space junk is in orbit around Earth, meaning that, while Earth's gravity continuously pulls it down, it is moving so fast laterally that it never hits the ground.
Most common elements in space?
Hydrogen and helium.
What could the results be of an impact of space junk and asteroids into the asteroid belt?
It is more likely to pass right through than impact anything as most of the asteroid belt is empty space.
What pieces of equipment have actually flown through and studied most of the solar system?
the space shuttle for one
Why can't a satellite in space never hit a human?
Actually, it can. It is a very rare occurrence, but pieces of a decending satellite can hit a person, but since most satellites burn up in the atmosphere, and only large satellites can have piece survive the burnup, the chances that someone will be hit by one is very, very small. In the Space Station or Space Shuttle, that is a different story. The ground control works to prevent pieces of old satellites and "space junk" from hits the shuttle, or station, or astronauts. In fact, one paint chip from an old satellite or rocket booster did hit the Space shuttle's thick window, causing the outer layers to shatter.
