As long as humans have been exploring space, they have also been creating mess. This is called space junk. All space junk is the result of us launching objects from Earth, and it remaining in orbit until it re-enters the atmosphere.
What Is Causing Space Junk?
There are many man-made debris in orbit which includes old satellites and parts of used rockets, as well as the bits broken off and collisions. Space debris also includes a glove lost by astronaut, a camera lost by Michael Collins, a thermal blanket, lost garbage bags, a wrench and a toothbrush. Most have come from exploding rocket stages and satellites.
Space Junk In Numbers:
Active Satellites = 2,000
Dead Satellites =3,000
Pieces Of Space Junk Larger Than 10 Centimetres = 34,000
Pieces Of Space Junk Larger Than 1 Millimetre = 128,000,000
Why Is Space Junk Bad For Us?
- risk to spacecrafts
- our ability to use weather satellites
- collisions in space
Why Should We Decrease Space Junk?
There is lots of space junk and it keeps on increasing. It needs to deacrease as in the future it could become a serious problem. They might launch 10,000 to 20,000 satellites over the next 5 to 10 years; that is a lot of space junk to be made.
My opinion on space junk is that one day it will make a impact on our lives so I think we should try and decrease it. As we launch more and more we face an ever-increasing chance of collision. I think it could be solved by sending less objects into orbit; but then we will not have as good TV or internet. Otherwise, scientists are developing an object called OSCaR (Obsolete Spacecraft Capture and Removal), that would hunt down debris and bring it into orbit.
Overall I think that the OSCaR could be the solution to help stop space junk.
