Rescue Mission Launches to Save NASA’s Swift Telescope
A three-armed robotic spacecraft rocketed into orbit from the Marshall Islands on Friday in a race against time to rescue NASA’s aging Neil Gehrels Swift Observatory from burning up in Earth’s atmosphere. The mission, led by Arizona-based startup Katalyst Space Technologies under a $30 million NASA contract, represents the first American attempt at robotic satellite servicing of its kind, according to AP News.
Why Swift Is Falling
Launched in November 2004, the Swift Observatory — originally known as the Swift Gamma-Ray Burst Explorer — has spent more than two decades tracking some of the most powerful explosions in the universe, including gamma-ray bursts and exploding stars. But the telescope was never designed with its own propulsion system for orbit maintenance, and recent intense solar activity has accelerated its decline.
Solar storms and flares have heated and expanded Earth’s upper atmosphere, increasing drag on Swift and causing it to sink faster than anticipated. The observatory currently orbits at approximately 224 miles (360 kilometers) above Earth, and without intervention, it was projected to reach a point of no return by October 2026, after which recovery would be impossible.
“If we let Swift reenter, we would lose that telescope. We would lose a lot of capability,” NASA’s Science Mission Chief Nicky Fox told the Associated Press. “We don’t currently have the budget to build another one to replace that.”
The Rescue Plan
The rescue spacecraft, named LINK, was built by Katalyst Space Technologies of Flagstaff, Arizona, in just nine months — an extraordinarily compressed timeline for a space mission. Roughly the size of a small kitchen refrigerator with a 40-foot (12-meter) solar wingspan, LINK carries three arms, each with two finger-like pinching grippers designed to capture and secure the tumbling telescope.
LINK launched aboard a Northrop Grumman Pegasus XL rocket, deployed from the belly of the company’s modified L-1011 aircraft, Stargazer, at approximately 40,000 feet above Kwajalein Atoll in the South Pacific Ocean. The launch occurred at 8:36 p.m. Marshall Islands Time (4:36 a.m. EDT) on July 3, following a series of weather delays and a last-minute software issue that aborted an earlier attempt on July 2.
Shortly after reaching orbit, teams established communications with LINK and confirmed its solar panels had deployed and power systems were functioning, as NASA reported.
A High-Stakes Rendezvous
Over the next month, LINK will perform checkout procedures before approaching and surveying Swift. The spacecraft will then attempt to capture the 1.6-ton (1.4-metric ton) observatory using its three-armed gripper system and slowly raise its orbit by approximately 150 miles (240 kilometers) to a target altitude of about 373 miles (600 kilometers). The orbit-raising maneuvers are expected to take several months.
If successful, Swift could return to science operations by September 2026, continuing its role as what NASA describes as “the agency’s first responder” for transient astronomical events.
“This is a high-risk, high-reward mission,” Katalyst Space CEO Ghonhee Lee said ahead of liftoff, as reported by Deutsche Welle. “The biggest danger was always we don’t launch anything and we let Swift burn up in the atmosphere. So we were always trying to avoid that risk, and our team has done that.”
NASA’s Astrophysics Director Shawn Domagal-Goldman acknowledged the audacity of the endeavor: “I have to be honest. No one thought it was going to be possible. No one thought we would get as far as we’ve already gotten today.”
Broader Implications for Space Infrastructure
The mission highlights a growing vulnerability of space infrastructure to solar activity. As the Sun approaches the peak of its 11-year solar cycle (Solar Cycle 25), increased solar flares are accelerating orbital decay for satellites in low Earth orbit — affecting not just scientific observatories but also communications and Earth observation platforms.
Only China has previously attempted a mission of this type, successfully boosting a satellite into a higher graveyard orbit in 2022. If LINK succeeds, it could open a new commercial market for in-space services including repair, refueling, and orbit adjustment.
Hubble Could Be Next
NASA’s Hubble Space Telescope, launched in 1990 and now 36 years old, is also losing altitude due to increased solar activity. Hubble received five servicing missions by spacewalking astronauts during the Space Shuttle era, but no further human servicing is planned. Katalyst’s next-generation robot, scheduled to fly in 2027, could potentially boost Hubble’s orbit as early as 2028.
“It’s a national treasure,” Fox said of Hubble. “People love Hubble.”
What’s Next
In the coming weeks, LINK will gradually approach Swift and begin survey operations. Capture and orbit-raising maneuvers are expected through August and September. If all goes according to plan, one of NASA’s most valuable scientific assets will resume scanning the cosmos from a safer altitude — and a new chapter in commercial space servicing will have begun.
NASA contracted Katalyst in September 2025 under the agency’s Small Business Innovation Research program, with the contract valued at $30 million — a fraction of the cost of building and launching a replacement observatory, which would run into the hundreds of millions or billions of dollars.
CEO Lee envisions an even bigger future: “This is the first American space robot to go up and do anything like this. NASA has all these big senior observatories … all of them can benefit from a service like this. So what we’re proving with this mission is this is a new play in the playbook that’s available.”
