Why is Hubble’s orbit getting lower?
Even at Hubble’s altitude, traces of Earth’s atmosphere create resistance as the telescope moves through them. This resistance, called atmospheric drag, gradually lowers its orbit rather than making it fall straight down.[1]
Hubble has no propulsion system to maintain its orbit, but it is still circling Earth and continuing its science work.[1]
What options is NASA exploring?
NASA is exploring several possible responses, from extending Hubble’s science lifetime to managing the end of its mission. The list shows the different kinds of action included in its request.[1]
- Boost Hubble to a higher orbit to extend its science lifetime.
- Service Hubble to enhance its capabilities.
- At the end of its mission, carry out a controlled re-entry or orbital disposal.
These are possibilities NASA is asking about, not announced missions.
NASA issued the request for information to commercial companies on October 29, 2026, and reported on it the next day.[1]
When might Hubble re-enter?
NASA predicts that Hubble will likely re-enter Earth’s atmosphere in 2033–2034 and anticipates that a mission would need to take place by 2032. These are estimates, not fixed dates.[1]
