Katalyst Space Preps LINK to Save NASA's $500 Million Swift Observatory

Summary
LINK has been readied for encapsulation at NASA's Wallops Flight Facility ahead of a fast-tracked mission to raise the orbit of the Neil Gehrels Swift Observatory before re-entry risk grows.
Swift has fallen from about 373 miles to roughly 249 miles in altitude, pushing NASA to use the robotic servicing satellite to rendezvous with and boost the aging observatory.
Pegasus XL will carry LINK on an air launch from Northrop Grumman's Stargazer aircraft at about 39,000 feet, adding a complex four-vehicle chain to the rescue attempt.
Swift launched in 2004 on a planned two-year mission to study gamma-ray bursts, and NASA is still working to predict its position for the orbital meetup.
With solar flares making its orbit erratic, can the rescue mission catch the tumbling Swift observatory in time?
Is saving a 21-year-old satellite the start of a routine 'roadside assistance' service for space?
Race Against Reentry: How LINK’s 2026 Robotic Servicing Mission Aims to Save the Neil Gehrels Swift Observatory
Overview
NASA's Neil Gehrels Swift Observatory is in urgent need of rescue in June 2026 because increased solar activity has caused Earth's atmosphere to expand, which significantly increases drag on satellites in low Earth orbit. This extra drag is making Swift's orbit decay much faster than expected, and early 2025 modeling predicted it would reenter Earth's atmosphere by summer 2026. Without intervention, Swift faces an uncontrolled reentry, risking the loss of a valuable scientific asset. The LINK mission aims to rendezvous with Swift and boost its orbit, offering a last chance to save the observatory and extend its scientific mission.
