After two scrubbed makes an attempt, Katalyst’s LINK servicing spacecraft reached orbit and phoned house — the primary steps in the direction of rescuing the 21-year-old Swift telescope from a decaying orbit and reentry.

NASA efficiently launched its mission to save the Neil Gehrels Swift Observatory on July 3, simply over 9 months after awarding the rescue contract to Katalyst Area Applied sciences — a turnaround that left virtually no room for error.
Northrop Grumman’s Pegasus XL rocket dropped from the stomach of the L-1011 plane Stargazer at roughly 40,000 ft (12,200 meters) above the Marshall Islands at 4:36 a.m. EDT Friday, delivering Katalyst’s LINK spacecraft to orbit. Groups then established communications with LINK, confirming its energy techniques and photo voltaic panels had come on-line.
The launch adopted two scrubbed makes an attempt. Climate delays on Wednesday, July 1, pushed the launch again a day. Then a software program challenge with Pegasus’s navigation system canceled the Thursday, July 2, try.
What’s Swift Enhance?
Swift Enhance is NASA’s try and preserve the ageing Neil Gehrels Swift Observatory from burning up within the ambiance. Elevated photo voltaic exercise has intensified drag on the spacecraft because it orbits the outer edges of Earth’s ambiance, dragging it down quicker than anticipated. Swift was designed with none thrusters of its personal, making it incapable of boosting its personal orbit. Fairly than let the observatory fall, NASA employed Katalyst to construct a robotic spacecraft able to grabbing Swift and hauling it again right into a secure orbit.
What’s the Swift Observatory?
Swift is a space telescope able to rapidly observing a variety of cosmic occasions in seen, ultraviolet, X-ray, and gamma-ray gentle. Launched in 2004 because the Swift Gamma-ray Burst Explorer and later renamed for gamma-ray astronomer Neil Gehrels, the telescope has spent twenty years detecting gamma-ray bursts — the universe’s most violent explosions — typically inside seconds of their prevalence, alerting different observatories to comply with up on the phenomenon.
In Could 2005, the observatory achieved one thing no telescope had managed earlier than: catching the afterglow from a short gamma-ray burst, confirming that these flashes come from colliding neutron stars. 4 years later, Swift noticed GRB 090423, a burst whose gentle had traveled greater than 13 billion years to achieve Earth, telling a story of the demise of a star and the beginning of a black gap from the earliest days of the universe.
What’s Katalyst Area Applied sciences?
Katalyst Area Applied sciences is a small Flagstaff, Arizona-based firm that builds autonomous robotic spacecraft designed to service, restore, and lengthen the lives of satellites already in orbit. In September 2025, NASA awarded the corporate a $30 million contract to construct the rescuer and get it to Swift inside a yr, a decent timeline that Katalyst executed flawlessly. “In underneath a yr, we’re going from identification of an issue, proposal, contract award to launch,” mentioned Kieran Wilson, Katalyst LINK lead, in a NASA promo video for the mission.
How will LINK enhance Swift?
As a result of Swift was not constructed with docking {hardware}, Katalyst engineered a customized seize mechanism that can use three LiDAR-guided robotic arms to latch onto a structural characteristic with out disturbing Swift’s devices. Over the approaching weeks, Katalyst will run LINK by checkouts of its navigation and propulsion techniques earlier than the spacecraft approaches Swift, surveys it to find out one of the best level of contact, and ultimately captures and lifts the observatory.
The seize itself might be particularly tough as a result of Swift was by no means meant to be touched once more as soon as it reached orbit. “No person took an image of the bottom of Swift earlier than it launched,” Katalyst CEO Ghonhee Lee told Aerospace America. Katalyst’s engineers needed to spend months finding out any pre-launch pictures of Swift that existed. According to Tech Times, they recognized small steel rings initially used throughout floor dealing with earlier than Swift’s launch as potential targets. No spacecraft has ever tried to make use of these flanges as docking factors in orbit earlier than. LINK has major, backup, and secondary backup grapple factors recognized, giving the crew room to adapt as soon as its survey confirms which spots have held up after twenty years in orbit.
Swift will truly assist in its personal rescue. “Swift is an unprepared however cooperative accomplice within the rendezvous,” mentioned Wilson, as reported by Tech Times. Whereas the observatory can’t enhance its orbit, it will probably management its personal orientation. Swift will be capable to help LINK within the proximity operations by sustaining the suitable orientation. As soon as the 2 spacecraft dock, LINK will hearth its thrusters to slowly increase the pair’s orbit over a number of months — a gradual climb again towards Swift’s unique altitude. If LINK succeeds, Swift will resume its publish, able to swing towards the following gamma-ray burst the moment its gentle reaches Earth.
