Private company proposes daring mission to save Hubble Space Telescope and tackle space debris.

Momentus and Astroscale, two space startups, have submitted a proposal to NASA to extend the lifetime of the Hubble Space Telescope while also cleaning up orbital debris in the vicinity. The proposal would use Momentus' space tug called Vigoride, which would launch on a yet-to-be-determined rocket and use Astroscale technology for rendezvous, proximity operations, and docking to reach the telescope. The tug would eventually move Hubble's orbit up by 31 miles and then turn to a new task of cleaning up orbital debris. The proposal is part of a private-public partnership, and NASA is still studying Hubble proposals issued in response to its request for information.
