The mission to save NASA’s sinking Swift Observatorywas called off Wednesday, dooming the telescope to a fiery reentry later this year.

NASA and Katalyst Space Technologies announced the news more than a month after the startup’s Link spacecraft rocketed away to the telescope’s rescue.

Katalyst said Link will not attempt to capture Swift and boost it to a higher orbit because of problems with controlling the spacecraft. NASA said this means the telescope will plunge through the atmosphere after more than 20 years of tracking some of the biggest explosions in the universe like gamma ray bursts and exploding stars. Its demise is not expected before October.

NASA paid $30 million to Katalyst in an attempt to raise the telescope to a safer, longer-lasting orbit. Intense solar activity caused it to lose altitude faster than expected. The rescue spacecraft went into an uncontrollable spin a few weeks after its liftoff in early July. While flight controllers managed to slow Link’s tumble, issues continued to plague its pointing and positioning in orbit.

“This is not the outcome we were working toward, but it does not change why this mission was worth attempting,” NASA Administrator Jared Isaacman said in a statement.

As a consolation prize, Katalyst will continue to operate Link in proximity with the telescope to demonstrate capabilities for future rescue operations.

Katalyst CEO Ghonhee Lee said it was an ambitious mission on an aggressive timeline that was thrown together in under a year .

“We took on this high-risk, high-reward challenge and are proud of the milestones we reached along the way,” Lee said in a statement. “We have already learned a tremendous amount.”

Launched in 2004, Swift’s science instruments were turned off earlier this year to slow its descent. It was orbiting 214 miles (345 kilometers) high as of Wednesday. Katalyst had hoped to lift the telescope back to its original orbit of 373 miles (600 kilometers), allowing for many more years of cosmic observations.

NASA’s Hubble Space Telescope could benefit from an orbital boost and had been next in line for a rescue attempt had this mission gone well. The 36-year-old Hubble is also dropping in orbit because of all the sun’s recent outbursts. It wasn’t immediately known whether Hubble is now out of luck.

NASA Updates Next Steps for Commercial Swift Boost Mission

Due to an ongoing commercial spacecraft attitude control issue, NASA and Katalyst Space announced Wednesday the LINK spacecraft will not capture or boost an agency satellite to a higher altitude to extend its science mission as planned. However, LINK still will attempt to conduct rendezvous and proximity operations with NASA’s Neil Gehrels Swift Observatory to demonstrate key capabilities for the future of space exploration.

“NASA should be willing to move quickly and take smart risks when the potential return is worth it, and that is exactly what we did with this mission,” said NASA Administrator Jared Isaacman. “This is not the outcome we were working toward, but it does not change why this mission was worth attempting. The team moved with extraordinary speed to give Swift a chance to carry out more science while advancing capabilities America will need for satellite servicing in the future. We are going to learn everything we can from LINK’s rendezvous attempt and put those lessons to work on the missions that follow.”

NASA and Katalyst are working closely to assess next steps for rendezvous and gather as much data as possible to inform future satellite servicing operations.

“We knew this was a high-risk, high-reward mission – a first-of-its kind attempt, developed on an unprecedented timeline driven by the Sun’s activity,” said Shawn Domagal-Goldman, director, Astrophysics Division, NASA Headquarters in Washington. “We were all hoping for more science from Swift. But we knew the takeaways from this mission would be worthwhile either way, and we have gained so much through the series of accomplishments up to this point.”

Without intervention, NASA anticipates Swift is likely to re-enter Earth’s atmosphere later this year. As part of the agency’s previous planning for Swift’s end of life, NASA will continue to prioritize finding new options to react rapidly to cosmic events, using current missions to help fill the gap in the meantime.

“Building, testing, and operating this mission has already strengthened America’s space industry pipeline, advancing in-space servicing capabilities in completely new ways,” Domagal-Goldman said. “NASA is committed to supporting our commercial vendors as they take on difficult tasks with the agency, to push the boundaries of what’s possible. We’re so proud of this team for: getting to the launch pad in record time, in a record-setting year for NASA astrophysics launches; its innovative problem-solving up to this point; and the dedication to the exciting capabilities this mission will attempt to demonstrate next.”

Swift was launched in 2004 to study gamma-ray bursts, the most powerful explosions in the universe, and other cosmic objects and events. It was designed for a two-year prime mission. After 21 years of science operations, Swift’s low Earth orbit began to rapidly decay because of increased solar activity. NASA used this opportunity to advance U.S. spacecraft servicing technology, awarding a contract to Katalyst in September 2025 to mount a robotic servicing mission for Swift in less than a year.

The LINK spacecraft launched July 3 on a Northrop Grumman Pegasus XL rocket from Kwajalein Atoll in the South Pacific Ocean. Teams established communications with LINK and conductedin-orbit checkouts over the following weeks, before the spacecraft experienced attitude control issues.
