NASA’s efforts to salvage the ailing Swift Observatory were halted on Wednesday, leading to the telescope’s inevitable re-entry into the Earth’s atmosphere later this year. Katalyst Space Technologies, in collaboration with NASA, confirmed the decision over a month after the launch of the Link spacecraft aimed at rescuing the telescope.
Katalyst revealed that due to difficulties in controlling the spacecraft, Link will not be able to retrieve Swift and elevate it to a higher orbit. Consequently, Swift, known for its two-decade-long mission of monitoring significant cosmic events like gamma ray bursts and supernovae, will descend through the atmosphere, with its demise projected for October.
In an attempt to save Swift, NASA had provided $30 million to Katalyst to raise the telescope to a more secure and sustainable orbit. However, unforeseen intense solar activity caused Swift to descend at a faster rate than anticipated.
Following a problematic liftoff in early July, the rescue spacecraft encountered an unmanageable spin. Despite efforts by flight controllers to stabilize Link’s motion, persistent issues with its orientation and positioning persisted in orbit.
Despite the unsuccessful rescue attempt, NASA Administrator Jared Isaacman emphasized the importance of the mission and its pursuit. As a silver lining, Katalyst will continue using Link in close proximity to Swift to showcase its potential for future rescue missions.
Katalyst CEO Ghonhee Lee acknowledged the ambitious nature of the mission, which was hastily organized within a year, marking a high-risk, high-reward endeavor that yielded valuable insights along the way.
Originally launched in 2004, Swift had its scientific instruments deactivated earlier this year to decelerate its descent. As of Wednesday, it was orbiting at an altitude of 345 kilometers, with Katalyst’s initial goal of reinstating it to its original 600-kilometer orbit for extended astronomical observations.
The future of NASA’s Hubble Space Telescope, which could also benefit from an orbital adjustment, remains uncertain. With Hubble also experiencing a decline in orbit due to recent solar activity, its fate following the Swift mission setback is yet to be determined.
