Quick Summary: According to NASA and Katalyst Space, a robot spacecraft launched to lift the Neil Gehrels Swift Observatory to a higher orbit is currently tumbling out of control following reaction wheel and thruster failures. Flight controllers are attempting to stabilize the spin using secondary thrusters to salvage the public-private servicing mission.
First Private Space Observatory Servicing Mission Suffers Major Control Failure
The mission marks the first time the space agency has hired a commercial vendor to hoist one of its observatories into a higher operating orbit, extending the life of a critical asset far beyond its initial design limits.
Launched on July 3 aboard a Northrop Grumman Pegasus rocket, the LINK spacecraft reached orbit to rendezvous with the Neil Gehrels Swift Observatory. Flight controllers spent several weeks commissioning the vehicle, powering up internal systems before initiating the orbital transfer sequence. Over the weekend, however, the spacecraft suffered severe attitude control malfunctions, resulting in an uncontrolled spin and sporadic communications caused by its antenna repeatedly sweeping away from Earth.
Technical Malfunctions Threaten Commercial Satellite Lifextension
The anomaly stems from simultaneous mechanical and propulsion failures aboard the LINK vehicle. According to NASA disclosures, two of the spacecraft’s three critical reaction wheels—devices used to precisely orient the vehicle without burning propellant—have failed completely. Compounding the issue, engineers identified persistent problems with one of the primary thruster systems.
Despite these setbacks, flight controllers are actively fighting to regain command of the vehicle. Operators are firing a secondary set of onboard thrusters to dampen the rotation rate. In a statement released to media outlets, mission managers confirmed that “we have already begun this series of burns and are seeing the intended effect.” Meanwhile, Katalyst principal investigator Kieran Wilson maintained in an interview with TechCrunch that “this remains an active mission, and we continue to move forward with plans to rendezvous with Swift.”

The Neil Gehrels Swift Observatory was originally launched in 2004 with specialized instruments designed to swiftly point at ephemeral space events, including distant gamma-ray bursts.
Tight Development Timelines and Commercial Pressures
Speaking to reporters ahead of the launch, Katalyst’s Kieran Wilson acknowledged the high-stakes nature of the project. He noted that the spacecraft had been built rapidly due to urgent orbital decay schedules facing the Swift observatory over the coming months.
“All this is challenging and risky,” Wilson said prior to launch. “There’re a lot of spacecraft that have had far longer development cycles with far more funding behind them that have failed for mundane reasons.”
