Is NASA Planning Another Mission to Fix the Hubble Telescope? A Closer Look

The Hubble Space Telescope (HST) has been a beacon of astronomical exploration and discovery for over 33 years, far exceeding its original 15-year lifespan. For many years, repairing this iconic telescope was as simple as sending a space shuttle up to service it. However, with the retirement of the space shuttle fleet in 2011, the question arises: is NASA planning to send another space shuttle to fix the Hubble Telescope in the future, and has it been fixed before?

The HST Fixing History

The short answer is no, although one might be tempted to say 'probably not.' After all, advancements in technology have made ground-based telescopes capable of performing much of the Hubble's work. Moreover, Hubble has outlived its original lifespan significantly, and the plan is to deorbit the telescope around 2030–2040. However, there have been proposals for missions to boost its orbit and/or repair its gyroscopes. Let us delve deeper into the history of Hubble repairs and current plans.

Initial Repairs and Maintenance

NASA had a series of missions to fix the mirror of the Hubble Space Telescope following its launch in 1990. These missions were routine and successful, with spectacular results. The Space Shuttle fleet, which was operational until 2011, made these repairs possible and highly effective. Several repair missions were conducted, and NASA astronauts worked tirelessly to keep the telescope operational and, more importantly, improving its capabilities.

Post-Space Shuttle Era

Since the retirement of the Space Shuttle fleet in 2011, no further repair missions to Hubble have been possible. A space shuttle was the primary method of repairing Hubble, and without such capability, NASA has had to explore alternative options. One promising direction is the use of the SpaceX Dragon, which can perform a reboost but lacks the necessary equipment for repairs, such as a robot arm similar to those used by the shuttle. SpaceX's Starship is another potential candidate, although it is still several years away from being ready for such a mission.

Current Proposals and Future Plans

NASA has received several proposals for Hubble repairs, including one from the satellite servicing company Astroscale in partnership with in-space transportation company Momentus. NASA is currently evaluating these offers, but no timeline for when an alternative solution might materialize has been provided.

Other options such as reboosting Hubble and potentially some additional servicing are also on the table. The SpaceX Crew Dragon, which can perform a reboost, is one viable option. It remains to be seen, however, whether the innovative Starship will be able to take over the role of the Space Shuttle someday. Yet, given the current timeline, it is uncertain whether Hubble will still be operational by that time.

Conclusion

The future of the Hubble Space Telescope is uncertain, with NASA exploring various options to extend its life and ensure its continued contributions to astronomy and space exploration. For now, the telescope's advancements and the significant results of past repair missions serve as a testament to its importance and the dedication of the professionals who have worked tirelessly to keep it operational.
