Northrop Grumman Space Systems's Pegasus XL is set to launch Swift Boost Mission no earlier than July 2026 from Kwajalein Atoll, Air launch to orbit. The countdown above is shown in your local timezone; the status updates live as the flight moves from To Be Confirmed to Go, and if it slips or scrubs. 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.
