I have not heard of anything, but these tugs may not be the best option. Northrup Grumman has already sent up two successful MEV missions (Mission Extension Vehicles), and they may be better options, as an MEV can also keep Hubble in a stable position after it finally fails and while we wait for a rescue mission, such as a future Starship flight. Remaining in a stable position is desirable while a Canadarm (or similar mechanism) latches onto Hubble for stability during the repair operations.

Once Hubble is back in operating order, perhaps the Starship can then service the MEV (e.g. refuel) for it to be used on other satellites.

I have not heard anything about this kind of mission, either.

Steve Richter: Just getting to and from orbit is hardly enough to make Starship ready to do a Hubble servicing mission. A lot of additional work needs to be done.

At the same time, Starship’s capabilities, once operational, make such a repair mission much more feasible. Do not be surprised if it gets proposed down the road, several years from now.
