Dream Chaser Hubble repair mission proposed
Though it has yet to actually go to space, the Sierra Nevada Dream Chaser spacecraft is floated as a possible savior for the Hubble Space Telescope, with a very preliminary mission proposal for a repair mission to the telescope which has now been operational in orbit for over a quarter of a century. The possible mission is brought forth as an example of increasing high-profile cooperation between NASA and private space companies. The Dream Chaser’s earliest orbit test flights are not expected to take place prior to 2019; if the mission takes place in 2020 at the earliest, Hubble will by then be 30 years old.
