Rescue mission called off for NASA Swift space telescope, setting up a fiery reentry

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

NASA and Katalyst Space Technologies announced the news last week, 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 such as 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. Although 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 Wednesday.

Katalyst will continue to operate Link in proximity with the telescope to demonstrate capabilities for future rescue operations.

Katalyst Chief Executive Ghonhee Lee, in explaining the failure, said it was an ambitious mission on an aggressive timeline.

“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 this year to slow its descent. It was orbiting 214 miles above Earth as of Wednesday. Katalyst had hoped to lift the telescope back to its original orbit of 373 miles, allowing for many more years of cosmic observations.

NASA’s Hubble Space Telescope also 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 also is dropping in orbit because of the sun’s recent outbursts. It wasn’t immediately known whether Hubble is now out of luck.
