NASA Seeks Commercial Rescue for Hubble Before Its Projected 2030s Reentry
Hubble has been sinking for 24 years, and no one has pushed back
Mark
Why does Hubble need rescuing at all? It's been up there for decades.
Mimi
It can't push itself. Columbia raised its orbit in 2002, the 2009 shuttle visit didn't reboost it, and it's dropped from about 583 km to 470 km since.
Mark
So the clock is orbital decay.
Mimi
Yes, with reentry projected for 2033 or 2034. Any mission has to fly by 2032, so the window is tight.
Luke
Before anyone gets excited: this is a Request for Information. No money is budgeted to buy a rescue flight. NASA is asking what's possible, not ordering anything.
Mark
And the cost? Is there any benchmark?
Mimi
The Swift rescue. Katalyst got $30 million and nine months, and NASA has signaled Hubble would get more of both.
Luke
Worth noting that mission closed to within about 10 km but was halted over power and reaction control problems. It's a reference point, not proof the approach works. And "more than $30 million" is a signal, not a figure.
Mark
Why not a crewed mission like Isaacman proposed in 2022?
Mimi
SpaceX plans to retire Crew Dragon by 2030, so that route looks unlikely now. Isaacman expects robotics companies to respond.
Luke
"Looks unlikely" is the reporting's judgment. Nothing in the notice formally excludes a crewed proposal, and we don't know who will respond.
The Pulse
- Hubble is losing altitude every year with no onboard engines to stop the fall, and reentry could come as early as 2033.
- NASA has issued a Request for Information with responses due November 30, but no money has been committed to any rescue flight.
- Any mission must reach the telescope by 2032, leaving a narrow window for companies to design, build, and launch a capture vehicle.
- A $30 million Swift rescue by Katalyst, which came within 10 km before halting, serves as a sobering cost and risk benchmark.
- Industry responses will decide whether a cheap robotic fix exists, shaping whether Hubble keeps observing into the 2050s.
Hubble, the telescope that has shown humanity distant galaxies for over three decades, is slowly sinking toward the atmosphere it was never built to descend through. NASA, facing a finite budget and an aging instrument with no engines of its own, has asked the commercial space world a simple and urgent question: can you lift it, service it, or bring it home safely before the decade closes? The answer will not be a rescue yet, only a measure of what is possible and what it might cost. In a sense, the question is how a species decides what its most cherished eyes are worth when keeping them open requires reaching up into the dark.
On Thursday, NASA asked the commercial space industry for help saving Hubble. Through a Request for Information, the agency wants proposals to capture the 36-year-old telescope, lift it to at least 600 kilometers, extend its working life through servicing, or guide it to a controlled reentry. Responses are due November 30, and any mission must fly by 2032 without damaging the observatory.
The underlying problem is simple. Hubble has no propulsion, and its orbit was last raised during a 2002 shuttle servicing mission. Since then it has descended from about 583 kilometers to roughly 470 kilometers. Without intervention, reentry is projected for 2033 or 2034, and a boost to 600 kilometers could give it another quarter century.
This is not the first attempt. In 2022, Jared Isaacman, now NASA's administrator, proposed a crewed Dragon servicing mission, and the agency received eight industry replies. The landscape has since shifted toward robotics, with Northrop Grumman, Astroscale, and Starfish Space all building servicing capabilities, and a crewed mission now looks unlikely.
The notice commits no funds. Officials want to learn who is interested and what a mission would cost. A recent Swift rescue, funded at $30 million, came close to success before ground teams halted it, and NASA has signaled Hubble would require more money and more time.
The stakes are high. Hubble is heavily oversubscribed, and its visible and ultraviolet vision has no direct replacement until the Habitable Worlds Observatory in the 2040s. Whether a affordable robotic rescue is possible will be answered by the responses that arrive after November 30.
On Thursday, NASA put out a call to the commercial space industry: tell us how to save Hubble. The agency issued a Request for Information seeking proposals to reboost the 36-year-old telescope, service it, or guide it to a controlled reentry. Without intervention, Hubble is projected to fall from orbit in the early to mid-2030s.
The notice sets out specific terms. Companies have until November 30 to respond. NASA wants details on current and near-term capabilities to capture the telescope, lift it to an altitude of at least 373 miles (600 km), or extend its working life through servicing upgrades. Any mission must leave the observatory undamaged and would need to fly by 2032, according to the solicitation.
The notice is exploratory. NASA has not committed funds to buy a rescue flight, and nothing is currently budgeted for procuring one. Officials want to learn who is interested, what a mission would cost, and which firms could realistically reach the telescope before it burns up. NASA Administrator Jared Isaacman said in a statement that Hubble still has important science ahead of it, and that if there are innovative, cost-effective ways to extend the life of an asset already on orbit, the agency owes it to taxpayers and the scientific community to explore them.
The problem is simple physics. Hubble has no propulsion of its own. Its orbit was last raised in 2002, when Space Shuttle Columbia flew a servicing mission. The final shuttle visit, in 2009, did not include a reboost, and the fleet retired two years later. Since then the telescope has been sinking, from roughly 362 miles (583 km) in 2002 to about 292 miles (470 km) today. Orbital dynamicists put reentry in 2033 or 2034 absent intervention, though solar activity can shift that forecast. A boost to 600 km would likely keep Hubble up for at least another 25 years.
Controlled disposal is also on the table. Hubble is massive enough that an uncontrolled reentry carries a small but non-zero chance of debris reaching the ground, so NASA is asking whether a commercial vehicle could grapple the observatory and bring it down safely.
This is not NASA's first search for help. In 2022, Isaacman, then a billionaire commercial astronaut, proposed flying a crew on SpaceX's Dragon to service and reboost Hubble, offering to pay most of the cost. NASA issued an RFI that year and received eight replies, including a joint robotic proposal from Astroscale and Momentus. In 2024, agency officials said they would pursue a reboost after reviewing the responses, while calling the SpaceX concept notional.
The landscape has changed. Isaacman now runs NASA. Northrop Grumman launched an advanced robotic servicing satellite this year in partnership with DARPA, and Astroscale and Starfish Space hold Space Force and NASA contracts for servicing and refueling demonstrations. A crewed mission like the 2022 plan looks unlikely, partly because SpaceX plans to retire its Crew Dragon fleet by 2030. In a post on X, Isaacman said he expects the solicitation to draw interest from robotics companies.
A recent rescue attempt offers a price reference. NASA gave Katalyst Space Technologies $30 million last year and nine months to build and fly a rescue craft to the Swift observatory. The company met the deadline and closed to within about 6 miles (10 km) of its target, but ground teams halted the approach after problems with the spacecraft's power and reaction control systems. NASA has signaled that Hubble, a far more valuable asset, would warrant more than $30 million and more than nine months.
The science stakes are high. Hubble draws roughly seven proposals for every available observing slot, and no true replacement is near. The James Webb Space Telescope and the forthcoming Nancy Grace Roman Space Telescope are tuned to infrared, while Hubble excels in visible and ultraviolet light. A comparable capability may have to wait for the Habitable Worlds Observatory, targeted for the 2040s. Nicky Fox, NASA's associate administrator for science, said industry has rapidly developed new capabilities for in-space capture and servicing, and that the agency is eager to explore ways to boost Hubble while it develops the flagship mission to follow.
After November 30, the responses will show whether a affordable robotic fix exists and whether anyone can reach Hubble in time. The answer will help decide whether the telescope keeps working into the 2050s.
