NASA's Swift Observatory rescue mission fails after Link spacecraft malfunction

Rescue Mission Initiated

NASA awarded Katalyst Space Technologies a $30 million contract last September to save the Neil Gehrels Swift Observatory. The mission aimed to prevent Swift, a $500 million observatory, from falling out of orbit. Katalyst was given nine months to develop and launch a satellite capable of capturing Swift and moving it to a higher orbit.

Link Spacecraft Launch and Malfunction

Katalyst's rescue spacecraft, named Link, successfully launched on July 3. After initial checkouts, the spacecraft experienced a malfunction a few weeks later, causing it to spin out of control. NASA announced in August that Link would be unable to reach Swift as intended, resulting in the abortion of the rescue mission.

Achievement in Rapid Development

Despite the mission's failure, the rapid development of the Link satellite was notable. Designing, building, and testing a satellite of Link's complexity, weighing nearly half a ton with electric thrusters, robotic arms, and large deployable solar arrays, typically takes several years. Katalyst completed this process in nine months.

Impact on Scientific Research

The failure means Swift, which has unique capabilities in gamma-ray, X-ray, and visible light detection, will deorbit. Scientists rely on Swift for detecting gamma-ray bursts, which are the most powerful explosions in the Universe. Swift, launched in 2004, had already exceeded its original design life and lacked its own propulsion system to raise its orbit. Increased solar activity accelerated its orbital decay.
