Reuters notes that the mission is viewed not only as a technological breakthrough but also as an important milestone in the space race between the U.S. and China.
New Technology to Extend Satellite Lifespan
The launch took place on July 3 using a Northrop Grumman Pegasus rocket, which launched from a Lockheed TriStar aircraft over the Pacific Ocean. The LINK robotic spacecraft was developed by the startup Katalyst Space Technologies under a $30 million contract with NASA.
Within a month, the spacecraft is expected to approach the Neil Gehrels Swift Observatory (SWIFT), which has been in operation since 2004. Using a sensor system, attitude control thrusters, and three robotic arms, LINK will attempt to capture the satellite and transfer it to an orbit approximately 600 km high.
Without this operation, SWIFT—which has no propulsion system of its own—would very likely have reentered the atmosphere and burned up this year due to atmospheric drag.
Testing Technologies of the Future
For NASA, the mission has much broader significance than simply extending the operational life of a single scientific spacecraft worth about $500 million.
Reuters emphasizes that this is, in fact, the first U.S. demonstration of satellite in-orbit servicing technology—a field that could transform the approach to operating space infrastructure. In the future, such spacecraft will be able to repair, relocate, refuel, and maintain satellites instead of replacing them with new ones.
After completing the main operation, LINK plans to conduct a series of additional maneuvers in close proximity to SWIFT, testing autonomous rendezvous and in-orbit control technologies.
The space race is reaching a new level
The mission is taking place against the backdrop of intensifying technological competition between the United States and China.
In recent years, China has already demonstrated the ability to approach and maneuver satellites in orbit, including an operation to move one spacecraft with another.
In Washington, such technologies are viewed as having dual-use capabilities—they can be used both for satellite maintenance and for military purposes.
According to Katalyst CEO Gonhi Li, the successful completion of the mission will significantly reduce the cost of extending the service life of expensive spacecraft and pave the way for the creation of an entire fleet of orbital service robots capable of servicing government and commercial satellites.
