Two distinct robotic missions are currently attempting to extend the operational lifespans of aging space assets, signaling a potential shift in how spacecraft are maintained. These efforts move away from the historical practice of treating satellites as disposable items, a norm driven by the high cost and technical difficulty of in-space servicing.
Advances in robotics and rocketry have made routine maintenance increasingly feasible, offering a way to preserve unique scientific instruments and reduce the accumulation of orbital debris.
Katalyst Space Technologies is operating the Lightweight In-Space Navigation and Kinematics (LINK) spacecraft, which launched in early July to assist NASA’s Neil Gehrels Swift Observatory. The Swift telescope, originally deployed in 2004, has been experiencing orbital decay. Shortly after its launch, the LINK spacecraft experienced control issues and intermittent communication problems.
Mission controllers have since stabilized the vehicle, but its ability to complete the mission remains uncertain. In the coming months, the spacecraft must travel to the telescope, located approximately 190 miles above Earth, and use three robotic arms to grapple the instrument and boost it to a higher orbit.
Shawn Domagal-Goldman, director of NASA’s astrophysics division, acknowledged that challenges were expected during such a complex operation. He stated that the team still sees a pathway to success, noting that the spacecraft’s capabilities are sufficient to secure the telescope and extend its operational life.
The Swift Observatory cost approximately $250 million to develop and launch, while Katalyst was paid about $30 million for the rescue effort.
Northrop Grumman’s Mission Robotic Vehicle (MRV) is pursuing a different objective in geostationary orbit. Launched last month, the MRV carries a payload co-developed by DARPA and the U.S. Naval Research Laboratory. It is currently traveling to the Optus D3 communications satellite, which orbits about 22,000 miles above Earth’s equator to serve Australia and New Zealand.
