A planned rescue mission for a NASA space telescope has been postponed due to a last-minute technical problem at the launch site. The mission, intended to extend the life of a valuable scientific instrument, is now grounded as engineers work to resolve the issue.
The telescope in question requires servicing to correct its trajectory and prevent its eventual decay. The specifics of the last-minute launch problem have not been publicly detailed, but the delay means the crucial repair window may be impacted.
Engineers from Katalyst Space, the company behind the rescue spacecraft, were seen with their vessel at NASA's Goddard Space Flight Center in April 2026. The spacecraft underwent thermal vacuum testing at the facility. The mission aims to provide a vital boost to the telescope's operational lifespan, allowing it to continue its scientific observations.
