Thanks for posting that. I've been following the articles from several orgs and companies who want to do something with the dead Sat's and boosters in orbit. It would make a great topic of discussion if we had a good following here on Ihub. There's a number of companies who want the Sats to be declared "hands off". Presently recent gov regulations require new Sat's have the ability to self de-orbit when it is no longer performing a job. The biggest problem with space junk are the second stage boosters that eventually end up exploding in orbit.
The ESA "Space Harpoon" is a tool that can be used, but there are also other options these days being worked on. Is a dead Sat a hazard or an asset waiting to be claim ? Both the DOD and Nasa are spending millions to develope a robot to recycle parts from Sats in orbit and bring some back to life.
I hope to have a forum on Lagrange City dedicated to discussing "Is that piece of Space Junk a hazard or an asset waiting to be harvested ?".
