NASA asks industry how to save Hubble before it falls

NASA wants commercial ideas to reboost, service or safely deorbit the Hubble Space Telescope. The mission would need to fly by 2032; responses are due Nov. 30.

The Hubble Space Telescope is slowly sinking, and NASA is once again asking private companies whether they can do something about it. On Oct. 29 the agency's Goddard Space Flight Center published a Request for Information (RFI) on commercial in-space servicing for Hubble, NASA announced. Ars Technica first highlighted the renewed push.

Three options on the table

NASA wants to hear about current and near-term capabilities for one or more of these missions:

  1. Reboost: capture Hubble in low Earth orbit and push it to an altitude of at least 600 km (about 373 miles) to extend its science life.
  2. Servicing: a visit that improves the observatory's performance and makes it more resilient to ageing.
  3. Controlled reentry: guide Hubble to a safe disposal instead of letting it fall uncontrolled.

Any mission must not harm the telescope and is expected to take place by 2032. NASA would supply technical data, access to its Hubble experts and coordinated telescope operations for rendezvous and capture. The company would have to provide everything else: the launch vehicle, the servicing spacecraft, mission operations and, if the plan involves astronauts, the crew.

Why the deadline is 2032

Like everything in low Earth orbit, Hubble loses altitude to atmospheric drag, and it has no engine of its own. According to the RFI, a lifetime analysis from July 2026 put the chance of reentry at 10% by September 2032 and 50% by December 2033. Forecasts can shift with solar activity, which puffs up the upper atmosphere and increases drag.

NASA makes a strong case for keeping the 36-year-old telescope alive: proposals for observing time outnumber available slots by more than 7 to 1, Hubble's data feed over 1,000 scientific papers a year, and its ultraviolet and visible-light capabilities have no replacement expected before around 2040, when the proposed Habitable Worlds Observatory could be ready.

Not a contract yet

The notice is explicitly not a request for proposals, and NASA has not said how much it would be willing to spend. Responses are due by 3 p.m. EST on Monday, Nov. 30. The idea isn't new: in 2022 NASA studied a SpaceX proposal to reboost Hubble with a Crew Dragon, but decided in 2024 not to pursue it at that time.
