In Simple Terms
The Hubble Space Telescope is still working, but the thin air around Earth is slowly pulling it lower. NASA is exploring whether a spacecraft could help keep Hubble in space longer, though no rescue mission has been approved. If extending its life is not practical, the agency may instead plan a safe end to its mission.
A Working Telescope, but a Changing Orbit
After more than three decades of watching the universe, Hubble faces a practical question as important as any of its discoveries: Can it stay in space, and if so, how? On October 29, NASA issued a request for information about in-orbit servicing capabilities, inviting ideas that might raise Hubble’s orbit or otherwise improve its capabilities. At the same time, the agency is considering ending the mission as one of the options it wants to assess.
The current concern is not that Hubble has stopped observing or suffered a reported failure in its instruments. According to information released by NASA, the telescope is still working well. The problem is its location: drag from the atmosphere around Earth is gradually pushing it into a lower orbit. The air is extremely thin where Hubble flies, but its effects build over time, lowering the telescope until it is expected to reenter the atmosphere unless something changes.
NASA estimates that Hubble could reenter the atmosphere in 2033 or 2034. Given that timeline, any attempt to extend its life would need to take place in 2032, the agency said. That leaves little room for planning and execution. A mission would have to be studied well in advance, and a spacecraft capable of reaching the telescope and working with it in orbit would need to be available.
NASA’s October 29 request for information is not an announcement of a mission ready to launch, nor does it mean a rescue has been approved. It is an effort to find out what organizations with expertise in space servicing might be able to offer and to gather ideas for practical options. Raising Hubble’s orbit is one possibility; the request also allows for proposals that could improve its capabilities in some way. NASA has not released specific details about a spacecraft design or how any such work might be carried out.
A Scientific Legacy That Cannot Be Replaced Overnight
Hubble began its journey in April 1990 as a joint project between NASA and the European Space Agency. Since then, it has become a central observatory for studying the universe, contributing data to research on planets, stars, galaxies, and many other celestial objects and phenomena. Among its most significant contributions was helping show that the universe’s expansion is accelerating, a finding associated with a Nobel Prize-winning discovery.
The observatory’s impact is not limited to a single discovery or a famous image. NASA estimates that Hubble observations have contributed to at least 23,000 scientific papers. Demand for telescope time far exceeds what it can provide: According to NASA, astronomers request about seven times as many observing hours as are available each year. That gap shows why keeping Hubble operating is more than an emotional response to its long life. Researchers still want to use the telescope more than its schedule allows.
Hubble also sometimes works in coordination with other observatories, contributing observations to joint programs. Keeping it in service could therefore give scientists more time to use its data and compare its observations with those from other instruments. But scientific value alone cannot settle the question. Any proposed mission would need to be feasible and safe, and its benefits would have to justify its costs and risks.
The observatory also has a prominent place in public life. Its images—including familiar views of the Pillars of Creation in the Eagle Nebula—have made distant parts of the universe recognizable to millions of people. That public connection is another reason people care about Hubble’s future, but it does not remove the engineering challenges. The telescope has been in orbit for decades, and approaching it or changing its path would require careful planning.
From an Earlier Proposal to a New Look at the Options
The idea of servicing Hubble is not new. In 2022, technology entrepreneur Jared Isaacman proposed using equipment from SpaceX for a mission to service the telescope. NASA did not approve the proposal at the time, expressing concern that docking with or otherwise intervening on an observatory that was working properly could expose it to unnecessary risks.
Isaacman’s role has changed since then: He became NASA administrator in December 2025. In a statement issued on October 30, he called for examining every reasonable opportunity to keep Hubble productive for as long as possible, while weighing whether extending its life would cost less than launching a replacement mission. In a post that same day, he said that exploring the options was still worth the effort and noted that NASA had previously considered a less expensive way to keep the telescope in orbit.
Isaacman has previously taken part in crewed orbital flights aboard SpaceX vehicles. He purchased and commanded two flights to Earth orbit, in September 2021 and September 2024. Those trips do not mean that a plan to service Hubble is ready, or that the earlier proposal has been revived unchanged. NASA is now reassessing the issue at the agency level and seeking information about servicing capabilities; it has not confirmed that a spacecraft, crew, or budget has been approved.
Rescue Is Not the Only Option
Alongside servicing the telescope or raising its orbit, NASA’s request includes a different possibility: planning a safe, controlled return to the atmosphere or placing the telescope in a suitable orbit at the end of its mission. Including this option makes clear that the discussion is not about saving Hubble at any cost. NASA wants to compare extending the mission with a responsible way to end it if an intervention is not practical or economical.
The difference between an expected return caused by the gradual lowering of Hubble’s orbit and a planned return is that a planned return would let NASA manage the end of the mission rather than leaving it entirely to the changing orbit. However, the source material does not provide details on how either scenario would work or how much control over Hubble’s path would be possible. For now, these are options NASA wants to study, not final plans, and their outcomes cannot yet be stated with certainty.
Before a servicing proposal could move from an idea to action, it would have to answer some basic questions. What spacecraft could reach Hubble? What kind of intervention would be possible? How could the risks to a telescope that is still working be limited? And how would the cost compare with other options? The information NASA has released does not provide detailed answers, but the request gives the agency a way to explore what organizations in the field might offer.
Timing is especially important. If Hubble is expected to reenter the atmosphere in 2033 or 2034, NASA has identified 2032 as the year for any servicing attempt. That means the options would need to be studied well before then, leaving enough time to approve and design a mission and prepare for it. Delaying a decision could narrow the available choices, even if a promising idea emerges on paper.
What Will Decide Hubble’s Fate?
NASA is weighing benefits against risks and costs. Keeping Hubble operating could preserve an observatory with a long scientific record that researchers are still eager to use. But servicing an old spacecraft in orbit is not simple, and NASA previously rejected a proposal in this direction because of concerns about the observatory’s safety. It is not enough for a rescue to be desirable; it must be possible without putting the telescope’s remaining life at greater risk.
Comparing costs does not necessarily mean that launching a new mission would be the obvious choice, or that extending Hubble’s life would automatically be cheaper. Isaacman’s statement identifies cost as one of the questions to examine, but it does not announce the results of a financial analysis or a decision to allocate resources. Likewise, the request for information does not name an organization that will carry out a mission or establish that NASA will choose any proposal it receives.
What is clear so far is that NASA has reopened the question of Hubble’s future and asked for information about ways to deal with the telescope in space. The agency has only a few years before the anticipated atmospheric reentry, but it has not announced that Hubble will be moved to a higher orbit or that a new servicing mission will take place. With a scientific legacy stretching back to 1990, continued demand for its observations, and real risks involved in intervention, the decision will depend on what a study of the options reveals.
The Bottom Line
Based on the information NASA has released, Hubble is not facing a failure that has halted its work. Instead, its orbit is gradually lowering because of atmospheric drag, bringing it closer to the end of its time in space. NASA wants to find out whether an in-orbit servicing mission could extend the telescope’s life or whether a safe end to the mission would be the better choice. Hubble’s importance—reflected in more than 23,000 scientific papers and demand for about seven times the observing time available—makes an extension worth investigating, but does not guarantee one. With reentry possible in 2033 or 2034 and any servicing attempt targeted for 2032, the answer will depend on safety, feasibility, and cost, not desire alone.
