Before I did the questions I though that..

What is space junk?

My hypothesis: I thought space junk was just all metal and steel. But there is more things then just that.

Is space junk a good thing or bad thing? My Hypothesis: I knew that space junk was a bad thing because there is nothing good about it except its recyclable. Space Junk is dangerous for astronauts in space fixing space crafts.

What causes space junk?My Hypothesis: I thought that space junk was caused by the rockets letting go of the fuel tanks and humans throwing rubbish they don’t need there.

Debris pronounced De-Bri is the scientific word for Space Junk.

Space Junk can be anything from nuts, bolts, gloves and other metals/steels.

Space Junk is mostly larger then a baseball.

It is estimated that there is 2million pounds of space junk out there.

There us over 4 million space junk orbiting around Earth.

And there is over 10,000 man made objects

Space is defiantly a bad thing it is very dangerous and can be harmful to human exploration, even a small flake of paint can cause huge damage to a space craft. Its dangerous because a 1mm metal chip can do as much as a 22 caliber rifle.

Space junk is caused by old space crafts, equipments and rubbish that has been left in orbit and is no longer in any use.

Space is mostly caused by exploding rockets.

The slip of an astronaut’s hand- suppose an astronaut doing repair in space drops a wench, its gone forever.
