Where's the tractor beam when you need it?the unfortunate part is that the most dangerous debris is also the debris requiring the most delta-v to grab.
Precisely, by the way I wonder what would be the cost of removal a piece of junk, probably astronomical. And this janitor creates junk of its own just by being in orbit and having been launched somehow. I would like to see a cost-benefit analysis.I don't see how it can efficiently remove enough junk to justify itself.
And unless they've got something super-cool like a solar sail, they can only carry so much fuel for delta-v. I don't see how it can efficiently remove enough junk to justify itself.
