# NASA cancels Swift telescope rescue after Katalyst LINK spacecraft tumbles

A spacecraft designed to boost the Swift observatory lost attitude control, ending the rescue attempt and shifting focus to proving servicing technology.

NASA and Katalyst Space Technologies called off the mission to rescue the Neil Gehrels Swift Observatory on August 20, 2026, after the LINK spacecraft lost attitude control in orbit [^10].

The LINK spacecraft launched on a Northrop Grumman Pegasus XL rocket on July 3 to capture Swift and push it 150 miles higher, but it began tumbling uncontrollably roughly three weeks later [^2]. Mashable reports that NASA declared the rescue failed due to problems with the LINK craft's attitude control system [^5]. Media Indonesia confirms NASA officially canceled the mission after the private spacecraft developed by Katalyst Space experienced the uncontrollable issues [^1].

Operators are now steering the tumbling spacecraft toward a backup objective: executing complex rendezvous and proximity maneuvers with Swift to prove out core technologies for future orbital satellite servicing [^7]. Interesting Engineering reports that Shawn Domagal-Goldman, director of the Astrophysics Division at NASA Headquarters, stated the lessons from the LINK mission will feed into the next generation of satellite servicing, refueling, and orbital debris remediation tools [^8]. SpaceNews reports that NASA Administrator Jared Isaacman stated the team moved with extraordinary speed to give Swift a chance at more science while advancing future servicing capabilities [^9].

Eos reports that NASA announced the original commercial effort by Katalyst Space Technologies to rescue the telescope [^3]. The agency said it will continue to prioritize finding new options to react readily to cosmic events, but noted that no current or upcoming telescope will look at the universe at the same wavelengths as Swift [^4].
