In Short: NASA has issued a Request for Information to commercial companies to explore ways to extend the life of the Hubble Space Telescope.

NASA has issued a Request for Information (RFI) to commercial companies to explore ways to extend the life of the Hubble Space Telescope, which has been in operation for over 30 years.

The RFI specifically seeks information on companies’ current and near-term capabilities for capturing Hubble and boosting it to an altitude of at least 373 miles (600 km), enhancing the telescope’s performance, or guiding Hubble to a controlled reentry.

The requirement includes that the boost and/or servicing mission must not harm the Hubble Space Telescope (HST) and that this mission is expected to occur by 2032.

Hubble, launched in 1990, has been a national icon that has fundamentally changed how humanity views the universe, according to Nicky Fox, associate administrator of NASA’s Science Mission Directorate.

The final shuttle servicing flight in 2009 did not reboost the telescope’s orbit, and with the retirement of the shuttle fleet two years later, Hubble has steadily lost altitude.

At its current rate of altitude loss, Hubble is expected to re-enter Earth’s atmosphere sometime between 2033 and 2034, potentially endangering human life.

Jared Isaacman, a billionaire commercial astronaut, approached NASA in 2022 about a servicing mission to Hubble with a team of astronauts on SpaceX’s Dragon spacecraft.

Isaacman proposed funding most of the mission, which would have reboosted Hubble by at least 30 miles (50 km).

It took 24 years for Hubble, which lacks onboard propulsion, to glide from its 2002 altitude of 362 miles (583 km) to its current orbit some 292 miles (470 km) above Earth.

The Hubble Space Telescope still shines in the eyes of astronomers after 36 years in orbit, but it is not as nimble as it once was.

Some outlets write 373 miles and others 372, which comes from rounding 600 km.

The Hubble Space Telescope has been operating for more than 30 years and continues to deliver discoveries that deepen our understanding of the universe.

What this adds

The RFI invites companies to express interest in three potential activities: boosting Hubble to a higher orbit to extend its scientific lifetime, servicing the telescope to enhance its capabilities, or safely disposing of it through a controlled atmospheric re-entry or orbital disposal at the end of its mission.

The observation it took on the day of its 200,000th orbit was characteristic of the very scientific objective for which Hubble was named: measuring the expansion rate of the Universe.

Background

The Hubble Space Telescope is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy.
