The technology to inspect, repair, refuel and retrieve satellites might actually reduce debris in orbit, though this can be confused with the technology to conduct reconnaissance on, sabotage, and capture satellites.

By “can be confused with” do you mean “is the same as”?

as long as the differences are classified, yes.

Northrop, the makers of this satellite, has a satellite system to do on-orbit refueling and refitments of some satellites. From a delta-V perspective the only place that makes economical sense to do so is for the geostationary satellites since they are all essentially spaced out along the same orbit. It would require very little delta-V to skip from one satellite to the next, as long as you had time to kill.

Trying to do orbital rendezvous with anything in a different orbit would require massive delta-V and a limited life cycle for the system. Spy satellites operating in Molniya orbits would be exceedingly difficult to rendezvous with.

While eyes were turned to French Guiana and the impending launch of the James Webb Space Telescope, for a few days around 17 December the spacecraft flew through the tail of Comet C/2021 A1 Leonard.
