NASA's Swift telescope dies as a rescue fails and a Goddard exodus bites

The rescue is off. NASA and Katalyst Space Technologies said on Wednesday that "ongoing attitude control issues" will keep the Link satellite from capturing the Neil Gehrels Swift Observatory and boosting it to a higher orbit, according to Ars Technica's report on 20 August. Swift launched in 2004 and is expected to reenter the atmosphere and break apart later this year.

The failure closes a gamble that NASA itself framed as a long shot. Less than a year ago the agency awarded Katalyst a $30 million contract to build and launch the rescue craft. NASA said Katalyst had to launch by this summer to reach Swift before it fell too low. Katalyst did the job in nine months, Ars Technica reported, a schedule that forced trade-offs. Two of Link's three reaction wheels failed. Its cold gas thrusters developed problems. That left plasma thrusters as the only way to regain control of a spacecraft moving at nearly 5 miles per second.

What Swift was for

Swift is not a sentimental loss. It detects and studies gamma-ray bursts, the most powerful explosions in the known universe, triggered by events such as the births of black holes and collisions between ultra-dense stars. Its combination of multi-wavelength instruments and fast pointing let it locate bursts for follow-up by other observatories. Astronomers have relied on that role for nearly 22 years, well past its original two-year design life.

That is exactly why the rescue attempt existed. Swift has no thrusters of its own to maintain orbit. According to NBC News, its problems began in 2024, during a period of intense solar activity: the Sun heats Earth's atmosphere, drag increases, and orbits decay faster than planned. The observatory had already paused operations ahead of the rendezvous attempt. Scientific American reported that the doomed telescope will leave a gap in high-energy observations that is unlikely to be patched soon.

Katalyst is not scrapping Link. The company said it will keep operating the spacecraft and may still approach Swift closely enough to demonstrate close-in navigation, a capability relevant to future satellite servicing. "We took on this high-risk, high-reward challenge and are proud of the milestones we reached along the way," CEO Ghonhee Lee said in a statement. NASA administrator Jared Isaacman said the outcome "does not change why this mission was worth attempting." Shawn Domagal-Goldman, director of NASA's astrophysics division, called it a first-of-its-kind attempt developed on an unprecedented timeline driven by the Sun's activity.

The quieter problem on the ground

The Swift failure is the visible loss. A second, slower one runs through NPR's 15 September report from NASA's Goddard Space Flight Center in Greenbelt, Maryland. Engineers there describe being moved out of laboratories repeatedly since last November, sometimes as recently as a month before the Nancy Grace Roman Space Telescope launched in late August.

NPR spoke with seven current and former Goddard scientists and engineers. Current employees asked not to be named, citing fear of retribution. Their accounts are specific. Propulsion engineers tested Roman's fuel with less sensitive gear because more precise tools were lost in a move, two engineers said. A radio communication lab lost almost all its equipment, including what one engineer described as a $6 million antenna chamber, before staff could test an antenna for Roman. A team working on the DAVINCI Venus spacecraft was delayed in August because its lab and a clean room had been cleared out in November and no replacement was provided. As of August, the engineer said, the vacated lab space was still empty.

NASA management told NPR the moves were aimed at cutting costs and eliminating "waste and redundancies," aligned with a published master plan, and would let the center avoid tens of millions of dollars in deferred maintenance. That rationale is in internal documents NPR reviewed. The engineers' counterargument is not about comfort. Spacecraft assembly requires custom rooms and machines, and losing them adds delay and risk to projects with billion-dollar price tags.

One engineer said a satellite, GRITSS, launched in July before it was ready, something they had never seen in more than a decade at Goddard. The team could not test its radio communications before launch. "We are half-blind in terms of trying to troubleshoot it," a scientist on the project told NPR.

"That only adds a whole lot of risk to an already risky endeavor," said Jack Kiraly, chief of advocacy at the Planetary Society. "These are potentially billions of dollars' worth of taxpayer investment."

What the two stories share

Read together, the two events describe a pattern rather than a coincidence. In orbit, a $500 million observatory is lost because a rescue was necessary and the rescue, built on a compressed schedule, did not work. On the ground, engineers say the infrastructure that builds and tests spacecraft is being dismantled faster than it can be replaced.

None of the people quoted in either report disputes the value of taking risks. Isaacman's defense of the Swift attempt is that NASA should move quickly when the return justifies it. Katalyst's Lee frames the program as a playbook for future rendezvous and servicing. Domagal-Goldman said the takeaways would be worthwhile either way.

The uncomfortable part is what cannot be recovered. Swift's replacement is not funded. Its science pauses permanently when it reenters, and the equipment engineers say they lost at Goddard does not come back with a change of policy. The Roman telescope reached orbit despite those conditions. The next one may not.
