The effort to rescue NASA’s Swift Observatory was officially halted on Wednesday, with the telescope expected to re-enter the atmosphere later this year.
NASA, in collaboration with Catalyst Space Technologies, announced this conclusion more than a month after Catalyst’s Link spacecraft attempted to launch a rocket for the observatory’s rescue.
According to Catalyst, the Link spacecraft will not pursue capturing Swift to elevate it into a stable orbit, citing difficulties in controlling the spacecraft. NASA indicated that this decision means the Swift will descend through the atmosphere after having spent over 20 years observing significant cosmic events, like gamma-ray bursts and supernovae, with its demise anticipated in October.
NASA invested $30 million in Catalyst to try to reposition the telescope for a longer operational lifespan. However, adverse solar activity caused its altitude to decrease more rapidly than initially projected. Following its launch in early July, the rescue spacecraft encountered uncontrollable spinning. Although flight controllers managed to stabilize its descent, orientation and positioning issues persisted.
In a statement, NASA Administrator Jared Isaacman remarked, “While this isn’t the outcome we aimed for, it was still a valuable mission.”
As a sort of consolation, Catalyst will maintain operations of Link near the telescope to showcase its capabilities for potential future rescue efforts.
Ghonhee Lee, CEO of Catalyst, mentioned that this was a bold mission with an ambitious timeline, all assembled within the span of a year.
“We embraced this high-risk, high-reward challenge and are proud of the milestones we achieved in the process,” Lee added, “We’ve already gained valuable insights.”
Swift’s scientific instruments, which were launched back in 2004, were deactivated earlier this year to help manage its descent. As of the latest update, the observatory was orbiting at an altitude of 214 miles (345 kilometers). Catalyst had aimed to restore the telescope to its original orbit of 373 miles (600 kilometers) for extended observation of space.
If the mission had succeeded, NASA’s Hubble Space Telescope might have been the next candidate for a rescue operation. The 36-year-old Hubble has similarly faced orbital challenges due to recent solar activity, but it’s unclear if it’s currently out of range for assistance.
