DARPA’s satellite servicing mission adrift
Week Three: Ninth Anniversary Fund-Raising Drive for Behind the Black
It is now the third week in my annual anniversary fund-raising campaign for Behind the Black.

Capitalism in space? DARPA’s program to test a satellite servicing mission appears in serious and complex trouble with the termination by Maxar (previously called SSL) of its contract to build the structure, or “bus”, of the robot.
What makes this more complicated is that the company building the actual servicing payload is continuing its work.
While Maxar will no longer be providing the satellite bus, work on the servicing payload continues. Among the companies involved in that effort is Praxis, a company handling planning for mission operations of the RSGS servicing system, such as how the system will safely grapple the target satellite. “For our day-to-day operations, that hasn’t really affected us. We’re pretty far along on the payload development,” said Tony Marzi, general manager of Praxis, during a presentation at the MIT New Space Age Conference at the Massachusetts Institute of Technology here March 15.
DARPA is thus calling for proposals to launch this payload.
The irony here is that this DARPA project was under criticism from the start, even to the point that a competing satellite servicing company, Orbital ATK, sued the agency. That company, now part of Northrop Grumman, was building its own privately funded servicing robot, and considered DARPA’s effort to be unfair in that it provided direct government subsidies to its competitors.
While Orbital ATK lost its suit, it now appears it has won the competition — assuming it eventually launches its own mission.

Is there a huge list of sats that can never be replaced so MUST be refueled and or augmented?
Just replace the satellites. That way you can update them and then make then fully serviceable in the future. Manufacture then with common replacement engine,fuel, and guidance systems.
