Katalyst Space's LINK Satellite Experiences Failures, Jeopardizing NASA Swift Observatory Reboost
Key points
- Katalyst Space's LINK satellite launched July 3 to reboost NASA's Swift Observatory.
- LINK is tumbling out of control due to two failed reaction wheels and thruster issues.
- The mission is NASA's first commercial contract for satellite servicing.
- Swift Observatory needs reboosting due to faster-than-anticipated orbital decay.
- Engineers are attempting to stabilize LINK using its plasma engines.
Satellite Experiences Control Issues
The LINK satellite, developed by Katalyst Space Technologies, is experiencing attitude control issues, causing it to spin in orbit and resulting in sporadic communications. NASA reported that two of the satellite's three reaction wheels are inoperable, and there is a partial loss of functionality in its cold gas thruster system. Reaction wheels are standard components used to control a spacecraft's pointing, while cold gas thrusters provide finer control, especially during rendezvous operations.
Mission to Reboost Swift Observatory
The LINK spacecraft was launched on July 3 aboard a Northrop Grumman Pegasus rocket with the mission to rendezvous with NASA's Neil Gehrels Swift Observatory. The Swift Observatory, launched in 2004, is designed to detect gamma-ray bursts and other ephemeral space events. It has been losing altitude faster than anticipated due to increased solar activity and requires reboosting to a higher orbit to continue its operations.
First Commercial Servicing Contract for NASA
This mission marks the first time NASA has contracted a private company, Katalyst Space Technologies, to provide orbital reboosting services for one of its observatories. Katalyst Space won a $30 million contract for this task, which aims to extend the operational life of the Swift Observatory. The incident with LINK jeopardizes this pioneering commercial satellite servicing mission.
Efforts to Stabilize LINK
Engineers are working to stabilize the LINK spacecraft. Through sporadic radio contact, they have discovered the issues with the reaction wheels and cold gas thrusters. Attempts are being made to use the satellite's plasma engines to slow its spin and regain control. The clock is ticking, as the Swift Observatory will be too low for a rescue attempt in a few months.

How outlets covered it
Katalyst Space Technologies' Link satellite, intended to service NASA's Swift gamma-ray observatory, spun out of control a week after its July 3 launch. Engineers are attempting to stabilize the spacecraft using its plasma engines to slow the spin, as two of its three reaction wheels and some cold gas thrusters failed. This incident jeopardizes the first commercial contract for NASA satellite servicing, with a tight deadline to boost Swift's orbit before it re-enters the atmosphere.
NASA's LINK spacecraft, launched to re-orbit the Swift observatory, is experiencing attitude control problems, including spinning and sporadic communications. This issue jeopardizes the mission to extend Swift's operational life, which is decaying faster than anticipated due to increased solar activity.
Katalyst Space Technologies' Link satellite, launched to save NASA's Swift gamma-ray telescope, is experiencing attitude control issues due to two failed reaction wheels and partial loss of its cold gas thruster system. This malfunction jeopardizes the mission to prevent Swift's reentry and burn-up, which is critical for detecting gamma-ray bursts.
A Katalyst Space robot, named LINK, launched to reboost NASA's Neil Gehrels Swift Observatory, is now tumbling out of control due to multiple system failures. This incident jeopardizes NASA's first mission to hire a private company for orbital reboosting services, potentially impacting the Swift Observatory's operational lifespan.
