Spacelaunch providing key support to pegasus xl nasa swift reboost mission

11 December 2025

SpaceLaunch announced today that it has been selected to support the upcoming Pegasus XL launch carrying Katalyst Space Technologies’ spacecraft for the NASA Neil Gehrels Swift Observatory reboost mission.

SpaceLaunch will provide Mission Management, Launch Vehicle Integration, and System Safety leadership for the mission. The company’s role includes ensuring technical readiness, regulatory compliance, and coordinated integration across all mission partners.

Scheduled for June 2026, the mission will launch Katalyst’s spacecraft designed to rendezvous with NASA’s Swift Observatory and execute a precision orbit-raising maneuver to extend the telescope’s scientific operations for years to come. The air-launched Pegasus XL rocket—the world’s only operational air-launched orbital vehicle—will deploy from a carrier aircraft over the Pacific Ocean. This flight will mark one of Pegasus’s final missions, underscoring the rocket’s three-decade legacy while bridging toward a new era of responsive small-satellite missions and on-orbit servicing technologies.

Marcy Mabry, CEO of SpaceLaunch added: “This mission represents a significant advancement in orbital servicing, and SpaceLaunch is honored to support making this possible. Our deep expertise in launch vehicle integration, system safety, and mission management allows us to support Pegasus XL where reliability matters most. We’re proud to contribute to this historic collaboration uniting heritage launch capability with cutting-edge in-space servicing technology.”

The Swift Reboost Mission stands as a milestone partnership between commercial industry and government science organizations, demonstrating how innovative spacecraft servicing can preserve and extend the life of critical national space assets.
