NASA calls off mission to rescue Swift gamma-ray observatory
Summary
NASA and Katalyst Space Technologies have canceled a mission to save the Swift gamma-ray telescope from falling out of orbit. The rescue satellite, Link, launched in July but lost control due to technical problems, making it unable to complete the rescue.Key Facts
- The Link satellite was launched on July 3 to attach to and boost the Swift Observatory to a higher orbit.
- Link is about the size of a refrigerator and uses solar panels and electric thrusters powered by xenon gas.
- Two of Link’s three reaction wheels, which help control its position, stopped working, causing the spacecraft to spin uncontrollably.
- Link’s backup thrusters were not strong enough to regain control for the mission to succeed.
- NASA gave Katalyst a $30 million contract to build and launch Link quickly—within nine months.
- The mission aimed to test technologies like robotic arms and sensors for future satellite servicing, such as refueling and repairs.
- Katalyst plans to use the mission’s remaining potential for testing and learning to improve future projects.
- This mission helped advance U.S. capabilities in space technology and satellite servicing.
