NASA’s Neil Gehrels Swift Observatory is in a tight spot. There’s a real chance it might crash back to Earth unchecked. To prevent this, a rescue mission is lined up using a Pegasus XL rocket, which hasn’t flown since 2021.
Katalyst Space Technologies, based in Flagstaff, is leading this effort. They’re set to launch their LINK spacecraft aboard the Pegasus XL in June 2026. If all goes as planned, it will have been five years since the last Pegasus flight.
As it stands, NASA estimates there’s a 50% chance the observatory could re-enter Earth’s atmosphere uncontrollably by mid-2026, and this number jumps to 90% by year-end. The Swift Observatory, operational since 2004, can still collect valuable data, particularly on gamma-ray bursts, if it can be moved to a higher orbit.
NASA awarded Katalyst a $30 million contract for this project, marking a milestone in space history. This rescue mission will be the first of its kind—using a commercial robot to capture a government satellite that wasn’t designed for repair.
Choosing Pegasus for this mission might seem surprising given its inactivity, but it’s actually a suitable option. Swift’s orbit is tilted at 20.6 degrees, making it tougher to reach from most US launch sites with typical rockets.
Ghonhee Lee, CEO of Katalyst, notes, “Pegasus is the launcher we need. It meets the orbit, timeline, and budget—key factors for using emerging technology.”
Kurt Eberly, director of space launch for Northrop Grumman, adds, “Pegasus offers unique benefits. It can be swiftly deployed anywhere and meets the strict requirements needed to save Swift.”
This mission isn’t just important for Katalyst and Northrop Grumman; it also shows a new approach to space challenges. If successful, it could pave the way for future commercial space solutions. As the space industry evolves, missions like this highlight the power of collaboration between government and private sectors.
Such advancements could resonate well beyond this rescue mission, potentially influencing how we handle aging satellites and their orbits in the future. You can follow more updates on NASA’s website here and Katalyst’s mission here.
