All the way back in 2013, we wrote about the Defense Advanced Research Projects Agency's (DARPA's) Phoenix program, aimed at launching a spacebound service robot capable of scavenging or even resurrecting dead satellites floating in the graveyard orbit.
While that program hasn't directly led to a satellite that can shear off and reattach solar panels, it has motivated real research and development. DARPA has announced that a sort of spiritual successor, the Robotic Servicing of Geosynchronous Satellite (RSGS) project, will get its first test launch in the summer of 2026. Rather than reusing components from old satellites, this new space robot will perform upgrades and fix simple malfunctions on satellites in the geosynchronous orbit range.
The project targets geosynchronous satellites because they are generally more expensive and have a much longer projected...
