Per NASA newsconference, HST will begin operating in one-gyro mode.
Three gryos are dead, the three improved gyros are still operating but
one has been giving bad data from time to time, causing safe-mode
operations. This will be kept offline as "from time to time" becomes
more frequent.

Hubble annual operations about $95 million.

(The improvement is in corrosion resistance.)

(Questions were asked about the proposed Polaris reboost mission)

NASA participants were Mark Clampin, director of the Astrophysics
Division of the Science Mission Directorate, and Patrick Crouse,
project manager of Hubble Space Telescope at Goddard. About 6 minutes
of prepared presentation, and the remaining time, about 35 minutes, for
Q&A.

BTW, for an interview with Mark Clampin, especially looking forward to
the Habitable Worlds Observatory, see Dr Smethhurst's channel ...

I very much doubt Hubble can be repaired by a Polaris (Crew Dragon) mission since they don't have a platform to attach Dragon to Hubble. Also, who's going to pay for all this? Isaacman is conjuring up this mission but I'm pretty sure he's not going to pay it out of his own pocket.

Hubble has what might be considered a docking adapter, fitted on the
lst servicing mission. How Dragon would use it is part of the TBDs
Clampin says need to be filled in before NASA would be giving the
go-ahead. And if the mission includes attaching external gyros to
Hubble, those would have to be developed.

NASA would be paying for it, as they would for a de-orbit mission.

No, but I bet he's paying for some of the early planning.

The Polaris mission is for reboost, not repair. At the NASA news
conference, NASA said they believe that thanks to the improved
corrosion-resistant gyros, Hubble can very likely operate in the
one-gyro mode to the end of the 2020's, and has about a 70% chance of
operating into the low 2030's (IIRC). So a repair does not seem very urgent.

I seem to be wrong about this.

Perhaps SpaceX and Isaacman are sharing the bill.

Isaacman discusses NASA's response with Ellie In Space:

While Clampin seems open to the proposal "eventually", he seems
confident that Hubble will keep going into the 2030s, and that too many
details need to be worked out to justify rushing into a solution. But
Isaacman thinks NASA is not being completely candid about Hubble's
health and that the current solar maximum reduces the time available.

I think Eric Berger feels the biggest push-back came from the Astronaut
Office. He spent some time chatting with NSF hosts before Flight 4

[One way to maybe resolve that would be to include NASA astronauts on
the Polaris Hubble crew, seems to me.]
