Rescue mission is called off for NASA’s aging Swift space telescope

(AP) — The mission to save NASA’s sinking Swift Observatory was 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. 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. 1 MIN READ 3 MIN READ 3 MIN READ 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 216 miles (347 kilometers) high as of last week. 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. ___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education and the Robert Wood Johnson Foundation.
