My group's mission at NASA is highly related: https://sspd.gsfc.nasa.gov/restore-l.html

We're going for LEO reservicing. It's quite a challenging mission, especially since our client was never meant to be reserviced let alone rendezvoused with in the first place.

Interesting project. A lot of the NASA publications keep the identity of the client very vague ("A satellite in LEO owned by the U.S. government" as one brochure puts it), which makes me suspect that it must be something "hush-hush" like NRO. Then I find a press release saying the client is Landsat 7 – https://www.nasa.gov/feature/nasa-s-restore-l-mission-to-ref... – which doesn't sound that "hush-hush" at all.

There was a time when we weren't exactly sure which client we were going to refuel, but as far as we know, it will be Landsat-7. I believe NRL and possibly others are working on reservicing more "hush-hush" clients, but I can't say for certain for that very reason haha.
