The Hubble Space Telescope will likely remain in use well into the middle of this century after NASA and SpaceX signed a Space Act Agreement. Hubble has been productive more than 32 years after its launch thanks to three servicing missions completed in the 1990s and 2000s. NASA believes that it will be the case until at least the late 2020s or 2030s. Many components of the telescope have been in space for decades, raising concerns about their longevity.
Hubble is guaranteed to eventually reenter that atmosphere and burn up without intervention because of the inexorable march of time, gravity, and Earth's atmosphere. It could come as early as the mid-2030s, but SpaceX thinks it could help extend the telescope's viability into the 2050s. In the next six or so months, NASA and SpaceX will discuss the possibility of using Dragon to boost the telescope's orbit back to a nominal 600 kilometers. Both parties say that the agreement will investigate the possibility of Dragon servicing missions, which could be even more significant for Hubble.

There is no guarantee that the telescope would be able to take full advantage of the extra time it would have with a boost that large. During the fifth and final Space Shuttle servicing mission, astronauts installed a docking mechanism on the Hubble Telescope. There were no plans for additional servicing missions, but the installation of that adapter made this study possible. It could be possible to boost Hubble's orbit far more feasible, safe, and affordable than a Shuttle-style crewed servicing mission. It is possible that an uncrewed Dragon could autonomously dock with Hubble, since it has the same docking capabilities its crewed sibling has and costs less to launch and operate. Jessica Jensen says that an uncrewed option will be studied along with crewed servicing and other alternatives.

Hubble is visible on the far right of the telescope. It isn't the same as the Dragon one, but it wouldn't be a problem to modify the existing one to work with Hubble's. Without a reboost, NASA would need to consider a separate mission to ensure a controlled deorbit of the Hubble Space Telescope by the end of the decade, according to Patrick Crouse, NASA's Hubble Space Telescope project manager. The boost of 40 to 70 kilometers could extend Hubble's lifespan by 15 to 20 years. As a feasibility study, there is a chance that it will conclude that using Dragon isn't feasible. The most likely outcome would be a conclusion that the project is out of reach from a financial perspective. He was involved in the September 29th press conference. The first all-private astronauts mission in history took place in September of 2021. The relationship between the two companies has become even closer after the success of Inspiration4. The Polaris Program intends to launch at least two or three more private astronauts over the next few years. The Polaris Program intends to debut the world's first privately developed EVA spacesuit, test spacecraft-to-spacecraft communications using Starlink's network of space lasers, and the first crewed launch of SpaceX's next-generation Starship. If realized, the decision to privately fund and develop an EVA suit and pursue the ability to conduct EVAs out of Crew Dragon represents a major leap forward for private spaceflight.

When asked about the synergies between the Polaris Program, SpaceX, and NASA, Isaacman revealed that he and SpaceX are willing to undertake a sixth Hubble servicing mission more or less pro bono, with little or no potential cost to the government. It is possible that a Hubble servicing mission could become the second Polaris Program mission. Polaris Dawn, the program's first mission, was recently delayed from a late-2022 launch target to March 2023. The four private astronauts assigned to the mission recently began training for the historic private EVA, which will see two of them attempt to briefly exit their Crew Dragon spacecraft in new SpaceX-designed suits. The spacewalk attempt will occur at a record-breaking altitude of 700 kilometers, and the mission will attempt to break the record for the highest Earth orbit reached by astronauts.
