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

NASA has decided to call off a rescue mission for its aging Swift space telescope, which is set to reenter the atmosphere later this year. The mission, which was initiated to lift the telescope to a safer orbit, was abandoned due to technical challenges with the rescue spacecraft. The telescope, launched in 2004, is expected to plunge through the atmosphere after more than 20 years of operation, and its demise is not expected before October. NASA paid $30 million to Katalyst Space Technologies to attempt the rescue, but the spacecraft failed to capture and boost the telescope to a higher orbit.

  • The telescope was damaged due to intense solar activity, causing it to lose altitude faster than expected.
  • The rescue spacecraft went into an uncontrollable spin a few weeks after liftoff, but flight controllers managed to slow its tumbling.
  • Katalyst will continue to operate the rescue spacecraft in proximity with the telescope to demonstrate capabilities for future missions.
  • The mission was an ambitious, high-risk project launched in under a year, and it was considered a high-reward challenge.
