There's a lotta junk in space, and figuring out how to remove it all has been a popular topic in the space community. Here's a new idea out of Russia: sink $2 billion into a roaming, pod-shaped craft that'll safely dispose of 600 dead satellites.
Just the other day we showed you one idea to clear the Earth's orbit of junk: giant balloons. Now, the Defense Advanced Research Project Agency is backing a proposal to build orbital vehicles that would scoop up debris in space using giant nets.
I don't know when you were in space last, but it's pretty messy up there. Even the smallest piece of debris is dangerous to the operational satellites, spacecraft and the International Space Station. So, how do we clean it up? With balloons, according to Dr. Kristen Gates.
