Nasa Telescope Doomed as Rescue Mission Fails
25 Sep
Summary
- Link spacecraft could not capture the orbiting observatory as planned.
- Nasa's Swift Observatory will re-enter Earth's atmosphere soon.
- Earlier in-flight issues hampered the Link robot's motion control.
The ambitious mission to extend the life of Nasa's Neil Gehrels Swift Observatory has concluded unsuccessfully, with the rescue spacecraft, Link, re-entering Earth's atmosphere after 85 days in orbit. Launched on July 3rd, Link, described as America's first commercial space robot, was tasked with lifting the observatory's orbit.
Despite getting within 7 to 9 miles of Swift and capturing images of its condition, Link was unable to complete its primary objective. Earlier in-flight problems, including issues with its reaction wheels that affected motion control and communications, prevented the robot from capturing the observatory as planned.
Consequently, Swift, a satellite that has observed gamma-ray bursts for two decades, faces its own demise. Without the rescue, Swift is expected to re-enter Earth's atmosphere in November. Nasa acknowledged the mission's high-risk nature, emphasizing its value in advancing spacecraft servicing technology and testing satellite operation capabilities.
Swift's operational lifespan was unexpectedly shortened by intense solar flare-ups, leading Nasa to suspend observations earlier this year and reposition the satellite. The failure of the Link mission underscores the challenges and risks inherent in complex space endeavors.
