=== Possible service missions ===
{{As of|2017}}, the [[First presidency of Donald Trump|Trump Administration]] was considering a proposal by the [[Sierra Nevada Corporation]] to use a crewed version of its [[Dream Chaser]] spacecraft to service ''Hubble'' some time in the 2020s as a continuation of its scientific capabilities and as insurance against any malfunctions in the James Webb Space Telescope.<ref name="Popular Mechanics-2017-02-03">{{cite news |url=http://www.popularmechanics.com/space/telescopes/a25211/mission-to-service-hubble-space-telescope/ |title=A New Spaceship Could Fly Astronauts to the Hubble Space Telescope for Repairs |work=[[Popular Mechanics]] |first=Jay |last=Bennett |date=February 14, 2017 |access-date=February 15, 2017 |archive-date=February 14, 2017 |archive-url=https://web.archive.org/web/20170214211431/http://www.popularmechanics.com/space/telescopes/a25211/mission-to-service-hubble-space-telescope/ |url-status=live }}</ref> In 2020, [[John Grunsfeld]] said that [[SpaceX Crew Dragon]] or [[Orion (spacecraft)|Orion]] could perform another repair mission within ten years. While robotic technology is not yet sophisticated enough, he said, with another crewed visit "We could keep Hubble going for another few decades" with new gyros and instruments.<ref name="foust20200615">{{Cite web |last=Foust |first=Jeff |date=June 15, 2020 |title=Hugging Hubble longer |url=https://www.thespacereview.com/article/3965/1 |access-date=June 16, 2020 |website=The Space Review |archive-date=June 16, 2020 |archive-url=https://web.archive.org/web/20200616040203/https://www.thespacereview.com/article/3965/1 |url-status=live }}</ref>

Billionaire [[Commercial astronaut|private astronaut]] [[Jared Isaacman]] proposed to fund a servicing mission using SpaceX spacecraft.
