Draft:Swift Rescue Mission

Swift satellite boost mission summary From Wikipedia, the free encyclopedia


The Swift rescue mission refers to an upcoming NASA and Katalyst Space Technologies joint venture to reposition the Neil Gehrels Swift Observatory to reposition the Swift satellite and alter its orbital path, extending the satellite's operational lifespan.[1]


Swift has been operational since 2004, and its altitude has naturally decreased over time from interactions with Earth's atmosphere, however, its increased orbital decay has been accelerated by additional drag from recent solar activity. [2] Swift's altitude has dropped from 600 to 400km.[3] Below 300km, chances of success for repositioning decrease. If no action is taken, Swift will reenter the atmosphere.

Katalyst was awarded $30 million USD for this mission.[4] Swift's entire operational budget is around $500 million USD, inflation adjusted.[5] Swift has no propulsion system, docking fixtures, or grappling points.[6] Katalyst's servicing spacecraft, LINK, will attempt to dock with Swift and raise its altitude.[7] LINK was designed with sensors and three robotic arms to grip Swift and attempt to move it without further damaging the satellite, approximately three weeks after launching.[8][7]

The rescue mission will be launched aboard the last remaining Pegasus-XL rocket, chosen partially for its air-launch capabilities, allowing for a reduction in cost in reaching Swift, as it orbits the equator and would have otherwise required a dedicated launch from other contemporary rocket companies.[9]

The mission is currently planned for June 2026.[10] Katalyst claims the mission could extend the Swift Observatory's lifespan by up to ten years.[11]
