NASA has posted a contract opportunity notice, also known as a request for information, from commercial space orgs who can service the Hubble Space Telescope. Hubble was always looked after by NASA astronauts flying on the Space Shuttle, yet the last Hubble Space Telescope (HST) servicing mission was the STS-125 Space Shuttle flight, launched on May 11, 2009. At the time, scientists hoped the mission would add another five years of operational life to the venerable spacecraft. Almost 17 years on, the HST (aka Hubble) is still delivering science. However, time is running out for the observatory. NASA reckons there is a 10 percent chance it could reenter the Earth’s atmosphere by September 2032, rising to 50 percent by December 2033. As the end of the Swift mission showed, increased solar activity can cause greater-than-anticipated atmospheric drag. Also, like Swift, Hubble has no propulsion system, and so when it reenters (as it will, without intervention), the reentry will be uncontrolled. Hubble is sufficiently massive that there is a remote chance somebody on the ground could have a very bad day when that happens. As such, one mission option suggested by NASA is a vehicle to grapple the observatory and perform a controlled reentry and disposal. However, there are other options. Something to boost the telescope’s orbit up to at least 600 km, or another to "enhance its ongoing performance and increase its resilience and expected on-orbit lifetime." Both are intriguing options, and important since, as NASA acknowledges, no replacement for Hubble is expected before the 2040s, when the Habitable Worlds Observatory (HWO) could become operational…
