LINK Rescue Satellite Spins Out of Control During NASA Mission

When a refrigerator-size satellite suddenly spun out of control more than 200 miles above Earth, it threatened an unusually urgent space rescue. The target of the pursuit is NASA’s Neil Gehrels Swift Observatory, a vital space telescope launched in November 2004 that has spent more than two decades tracking gamma-ray bursts across the universe. But increased solar storms since the fall of 2024 have heated Earth’s atmosphere, causing it to swell outward and significantly accelerate atmospheric drag on the aging observatory. Without a propulsion system of its own to fight the drag, Swift began descending much faster than anticipated.

The mission marks the first time NASA has hired a commercial company to service one of its government satellites that was never designed for in-space docking.

Technical Failures Strike the LINK Spacecraft in Orbit

The unprecedented rescue attempt hit unexpected turbulence over a weekend in late July 2026, just three weeks after the three-armed robotic spacecraft reached orbit. According to reports from AP News, the LINK satellite experienced severe thruster problems that sent it into an uncontrollable multi-axis spin, cutting off reliable communication with ground controllers near Denver. Engineers discovered that two of the satellite’s three reaction wheels, which are used for pointing, had stopped working, alongside a malfunction in the cold gas thrusters responsible for fine attitude control.

Recovery Efforts and Thruster Burns Slow the Spin

As ground teams worked around the clock, Katalyst chief executive Ghonhee Lee emphasized the high stakes and unpredictable nature of autonomous orbital operations. What keeps me up at night is the things that we don’t control, Lee told reporters regarding the complexities of the mission.

To arrest the rotation, engineers devised a creative fix utilizing equipment primarily built for other tasks. NASA and Katalyst updates confirmed that a series of plasma engine burns successfully reduced LINK’s rotation rate from approximately 9 degrees per second down to less than 4 degrees per second. Because the xenon electric thrusters feature a two-axis gimbal capable of vectoring their thrust, engineers repurposed them for attitude control to gradually calm the tumbling craft.

Next Steps and the Race Against Atmospheric Drag

With stabilization efforts making headway, the mission timeline has shifted slightly. LINK is now expected to approach Swift around the end of August 2026. Mission controllers are maintaining Swift’s average altitude safely above 185 miles to give the rendezvous attempt the highest possible margin of success before atmospheric drag pulls the observatory past the point of rescue.

Scientific observations aboard Swift remain paused while controllers keep the telescope in a drag-minimizing orientation. As Bradley Cenko, Swift principal investigator at NASA’s Goddard Space Flight Center, noted in agency releases, saving the multiwavelength observatory avoids the immense cost of building a replacement while testing an unprecedented capability for future space missions.
