"Companies propose missions to revive retired space telescopes"

Astroscale and Momentus have submitted a proposal to NASA to raise the orbit of the Hubble Space Telescope, which has been slowly descending since the last shuttle servicing mission in 2009. The proposal involves using Astroscale's technology to dock with and extend the life of satellites and orbital transfer vehicles from Momentus. The vehicle would boost Hubble’s orbit by 50 kilometers before undocking and could then be used to remove orbital debris in orbits approaching Hubble. NASA is currently reviewing eight responses to its request for information and emphasized that the RFI is simply an effort to help the agency determine whether and how to reboost Hubble’s orbit.
