A Chinese satellite pulled a defunct navigation satellite out of the way of other satellites on January 22nd. The satellite, called SJ-21, appeared to operate as a space tug when it grappled onto the navigation satellite from the Chinese CompassG2 network. The operation details didn’t come from Chinese authorities but a report by ExoAnalytic Solutions, a commercial space monitoring company.
Chinese authorities are tight-lipped about the operation, but what can observations tell us about Chinese capabilities?
SpaceLogistics LLC has achieved a first: it’s docked it’s maintenance satellite, called MEV-1, with another satellite in order to extend the life of the satellite. The docked pair will perform some check-ups, and if all goes well, MEV-1 will boost the client satellite to a higher orbit, extending its operational life-span by about five years.
Space Logistics LLC, a subsidiary of Northrop Grumman, has launched a satellite that can extend the life of other satellites. The satellite is called MEV-1, or Mission Extension Vehicle-1. MEV-1 is the first of its kind.
