NASA Rescue Mission for Aging Swift Space Telescope Abandoned
A daring attempt to extend the life of NASA's Swift space telescope has been abandoned after technical problems with the rescue spacecraft, leaving the observatory to burn up in the atmosphere later this year.
A $30m rescue mission to save NASA's aging Swift space telescope has been called off, condemning the twenty-year-old observatory to a fiery reentry into Earth's atmosphere later this year. The announcement, made jointly by NASA and the startup Katalyst Space Technologies on Wednesday, comes more than a month after Katalyst's Link spacecraft was launched on an ambitious mission to grab the telescope and boost it to a higher orbit. Problems with controlling the spacecraft's pointing and positioning, including an uncontrollable spin weeks after its July lift-off, ultimately proved insurmountable.
Katalyst confirmed that Link would not attempt to capture Swift, dashing hopes of extending the life of a telescope that has tracked some of the most colossal explosions in the universe, including gamma-ray bursts and exploding stars, for over two decades. Intense solar activity had caused Swift to lose altitude faster than anticipated, and its science instruments were turned off earlier this year to slow its descent. As of Wednesday, it was orbiting at an altitude of 214 miles (345 kilometres), far below its original orbit of 373 miles (600 kilometres) which Katalyst had hoped to restore.
NASA Administrator Jared Isaacman acknowledged the disappointment but defended the undertaking. "This is not the outcome we were working toward, but it does not change why this mission was worth attempting," he said in a statement. Katalyst's CEO, Ghonhee Lee, echoed the sentiment, describing the mission as a "high-risk, high-reward challenge" thrown together in under a year. "We have already learned a tremendous amount," he said, adding that the company would continue to operate Link near the telescope to demonstrate capabilities for future rescue operations.
The failure of the Swift rescue mission has significant implications for the future of another venerable NASA observatory: the Hubble Space Telescope. Now 36 years old, Hubble was next in line for a similar orbital boost, as it too has been dropping in altitude due to recent solar outbursts. With the Swift mission's failure, it remains unclear whether Hubble will now be left to suffer the same fate. The demise of Swift is not expected before October, marking the end of a mission that has provided unparalleled insights into the cosmos and underscoring the challenges of servicing and maintaining vital instruments in the harsh environment of space.
