Link, a spacecraft developed by Katalyst Space Technologies, is scheduled to launch June 27 on a Northrop Grumman Pegasus XL rocket. The air-launched vehicle will operate out of Kwajalein Atoll in the Pacific Ocean.
Link is designed to approach and then grapple NASA’s Neil Gehrels Swift Observatory, a gamma-ray observatory in low Earth orbit. The orbit of that spacecraft, launched in 2004, has been decaying due to atmospheric drag and could reenter as soon as late this year. Link will raise Swift’s orbit, allowing it to continue operations for years to come.

“Over the last nine months, we have gone from a clean sheet to a spacecraft that is currently integrated on a rocket on an airplane ready to go to Kwaj for launch,” said Kieran Wilson, principal investigator for Link at Katalyst. “This is an absolutely unprecedented development timeline.”
He credited the “exceptional urgency” NASA emphasized in the mission requirements. “When we set out, one of the very few requirements from the NASA team was, you must launch before it’s too late, and we have been able to meet that readiness timeline.”
Link must launch and reach Swift before that spacecraft’s altitude descends below 300 kilometers. Brad Cenko, principal investigator for Swift at NASA’s Goddard Space Flight Center, said Swift should reach that altitude in October based on current estimates of the spacecraft’s decaying orbit.

That capture and boost will be risky. Swift was not designed to be serviced and lacks grappling fixtures that Link could use. Link is also Katalyst’s first satellite servicing mission.
Wilson said the docking will be helped by the fact that Swift is still operational and can control its attitude. “Swift is an unprepared but cooperative partner in the rendezvous,” he said.
