NASA asks private companies for ideas to boost, upgrade or safely retire Hubble
In 60 seconds: NASA has asked private companies whether they could service the Hubble Space Telescope. A request for information issued on 29 October seeks ideas to lift Hubble to a higher orbit, upgrade its instruments, or bring it down safely at the end of its mission. Hubble has no engine of its own, and atmospheric drag could cause re-entry around 2033–34, so any mission must fly by 2032. Replies are due by 30 November.
Why it matters
Hubble has shaped modern astronomy for over three decades. Extending its life keeps a unique tool working, while a controlled exit avoids debris falling at random.
Explain it simply
An old scooter with no petrol slowly rolls downhill. NASA is asking if someone can give Hubble a push uphill, a tune-up, or a safe parking spot.
The 3-minute read
What happened
The request covers three options: a reboost to a higher orbit to extend science, servicing to upgrade capabilities, and a controlled re-entry or disposal at the end of the mission.
Background
Hubble's orbit is slowly decaying because thin air at that height drags on it. NASA Administrator Jared Isaacman said the telescope still has important science ahead.
How it works
NASA's Goddard Space Flight Center manages Hubble, and the Space Telescope Science Institute in Baltimore runs its science. Companies will reply to the request for information with their plans.
What's next
Responses are due by 30 November. NASA expects any mission would need to happen by 2032, before re-entry becomes likely in 2033–34.
What it means for you

Key numbers
- 2032: Deadline for any servicing mission
- 2033–34: Likely re-entry window without help
- 1990: Year Hubble was launched
- 30 Nov: Last date for company responses
Both sides
- NASA leadership: Hubble is a national icon and a cost-effective boost could keep its science going.
- Cautious observers: This is only a request for ideas; no company, cost or mission has been chosen yet.
Key terms explained
- Atmospheric drag
- The slowing force from thin air that gradually pulls low-orbit satellites down.
- Re-entry
- When a spacecraft falls back into Earth's atmosphere, where most of it burns up.
The story so far
- Apr 1990: Hubble Space Telescope is launched aboard Space Shuttle Discovery. Built by NASA with the European Space Agency, Hubble became the first large optical telescope in orbit, above the blurring effect of Earth's air.
- May 2009: Astronauts carry out the fifth and last servicing mission on Hubble. Space shuttle crews visited Hubble five times between 1993 and 2009 to fix and upgrade it. With the shuttle retired in 2011, no crew has reached it since.
- Today: NASA seeks industry ideas to service or retire Hubble
Exam notes (UPSC, SSC, Banking, PSC)
- The Hubble Space Telescope, launched in 1990, is a joint project of NASA and the European Space Agency (ESA).
- The James Webb Space Telescope (2021) observes mainly in infrared and orbits the Sun near the L2 Lagrange point.
- India's first dedicated space astronomy observatory is AstroSat, launched by PSLV in 2015.
- Atmospheric drag is the main reason satellites in low Earth orbit slowly lose height.
