Mission brief

The mission

Contracted by NASA under the Small Business Innovation Research Phase 3 contract, Katalyst Space Technologies' LINK servicing spacecraft will rendezvous and attach to NASA’s Neil Gehrels Swift Observatory to re-boost its orbit. This aims to demonstrate a key capability for the future of space exploration and extending the Swift mission’s science lifetime in gamma ray astronomy.
