Pegasus Swift Boost Mission

NASA's Neil Gehrels Swift Observatory is orbiting the Earth, but also slowly sinking. Katalyst Space’s LINK robotic servicing spacecraft will launch into orbit aboard a Northrop Grumman Pegasus XL rocket, then attempt to capture and raise the Swift Observatory satellite over the course of several months.

A Northrop Grumman Pegasus rocket will launch the Swift Boost Mission mission on Saturday, June 27, 2026 at 9:00 AM (UTC).
