A specialized spacecraft has been launched with the mission to rescue NASA's Swift Observatory, a powerful telescope currently in danger of falling back to Earth. The Link spacecraft, developed by Katalyst Space Technologies, was sent into orbit on Friday from the Marshall Islands in the Pacific Ocean atop a Pegasus rocket. This rocket was launched from a modified airplane.
The Link spacecraft is on course to reach and capture the Swift Observatory in approximately one month. Swift, which was originally launched in 2004, is experiencing a faster-than-usual orbital decay due to recent solar storms. NASA is investing $30 million in this mission, contracted to Katalyst, to capture the telescope and increase its orbital altitude. The objective is to enable Swift to continue its observations of significant cosmic events, such as gamma ray bursts and exploding stars.
If the rescue operation is successful, Swift could resume its astronomical observations by September. Currently, its scientific operations have been suspended to conserve its orbit for as long as possible. The mission is considered high-risk, according to Katalyst Space CEO Ghonhee Lee, but it aims to prevent the telescope from burning up in the atmosphere.
NASA's Hubble Space Telescope could potentially undergo a similar salvage mission in the coming years, as it is also losing altitude due to increased atmospheric drag caused by solar activity. The Swift Observatory, weighing 1.6 tons (1.4 metric tons), is currently orbiting at an altitude of 224 miles (360 kilometers) above Earth. Katalyst plans to raise its altitude by 150 miles (240 kilometers). The Link spacecraft will use its thrusters to gradually boost Swift's orbit, avoiding any abrupt movements.
Katalyst developed the rescue mission in a compressed nine-month timeframe at NASA's request, due to Swift's rapidly deteriorating orbit. Without intervention, the telescope is predicted to re-enter Earth's atmosphere in October. The launch faced several delays due to adverse weather conditions and technical issues.
