Rescue Mission for NASA’s Swift Observatory

A three-armed spacecraft was launched into orbit to rescue a NASA telescope that risks crashing back to Earth. Northrop Grumman sent the Katalyst Space Technologies’ Link spacecraft into space from the Marshall Islands. The Pegasus rocket lifted off from a modified airplane, setting Link on a path to reach and secure NASA’s Swift Observatory within a month.

Swift, launched in 2004, is sinking rapidly due to intensified solar storms. NASA has invested $30 million to ensure Katalyst captures Swift to elevate its orbit. This effort aims to enable the telescope to continue observing significant cosmic explosions, like gamma ray bursts and stellar detonations. If successful, Swift could resume its space scanning by September. Currently, observations are paused to maintain its orbit as long as feasible.

NASA may consider a similar rescue for the Hubble Space Telescope, experiencing altitude loss from solar activity. Swift, weighing 1.6 tons, orbits 224 miles above Earth. Katalyst plans to increase its altitude by 150 miles, restoring it to initial levels. Link will gradually boost Swift’s position to avoid intense jostling.

The preparation for this mission occurred over nine months, as urgency grew with Swift’s potential unrecoverable altitude drop by fall. Launch delays arose from weather and technical concerns. “This is a high-risk, high-reward mission,” stated Katalyst Space CEO Ghonhee Lee before the launch. “The main risk was not launching and allowing Swift to burn up in the atmosphere. Our team has worked to prevent that.”
