how to clean the waste satellites from the space without destroying .?
Answers
All human-made space objects result from the near-5000 launches since the start of the space age. About 65% of the catalogued objects, however, originate from break-ups in orbit – more than 240 explosions – as well as fewer than 10 known collisions. Scientists estimate the total number of space debris objects in orbit to be around 29 000 for sizes larger than 10 cm, 670 000 larger than 1 cm, and more than 170 million larger than 1 mm. Any of these objects can cause harm to an operational satellite. For example, a collision with a 10 cm object would entail a catastrophic fragmentation of a typical satellite, a 1 cm object will most likely disable a spacecraft and penetrate the International Space Station shields, and a 1 mm object could destroy subsystems. Scientists generally agree that, for typical satellites, a collision with an energy-to-mass ratio exceeding 40 J/g would be catastrophic. Image credit: ESA4

What’s the best way to clean up all the junk we’ve left in space?

This is a big problem that many people are still trying to figure out, because there is a lot of junk out in space, and it is incredibly dangerous.
As of September 2012, we are currently monitoring 21,000 individual pieces of stuff orbiting the planet which are larger than about 2 inches. Anything this size which is going fast enough to stay in orbit poses a significant threat to satellites, spacecraft, and space stations. The ISS will regularly maneuver out of the way of space junk if we see it coming soon enough. If there isn’t enough time to move the whole ISS, then the crew members of the ISS have to take shelter in one of the Soyuz capsules which are attached to the ISS in case an emergency evacuation is needed.
