Also, I am assuming that Orion would only support a "batteries and gyros" mission, and not swap of major instruments.

How is Orion supposed to grab Hubble. I know there is a passive SCM on Hubble, but how would Orion dock with it? If it use the docking port, no EVA could be performed, or could it?Dragon's trunk is much better for this. Also Dragon can carry much larger payloads that would not fit through a hatch.Anyway, the commercial option was debated 1 year ago:http://forum.nasaspaceflight.com/index.php?topic=28805.0

As much trouble as they had getting one of those last sets of gyros in, I don't think there's any way they try it with a robot.
What about a capsule with an arm? How would that be different from Shuttle? (this is a real question, not rhetorical)And supposing part of that answer is "airlock," suppose you brought a small airlock along with, docked to the end of the capsule? (With another port on the other side to dock with Hubble)
It seems to me that if you were to stretch the length and widden the current Orion service module
It seems to me that if you were to stretch the length and widden the current Orion service module to ratios approximating that of the old Apollo service module, while you would have to add fuel and oxidizer to the overall rig, there should be a significant amount of volume available for additional payload in one or two of the opposing quarter bays. (Sorry, forgot to meantion deviding the XXL Service Module into quarter bays) Two Quarter Bays should be enough volume to handle the increased fuel and consumable loads, while the other two bays would contain 1 robot arm each and the replacement equipment needed for the mission. Two robot arms, yes. One to hold the telescope and the other to hold the astronaut, equipment platform etc. (Yes, I know that they can tie off to the telescope itself, but you need a 'cherry picker' to bring them the gear that is needed for servicing). A four person crew should be sufficent for the task, and the SLS seems to have enough payload to orbit capibility to be able to handle such a mission.Jason
Where are the "batteries and gyros" going to be carried?
No airlock required. Orion's command module has airlock capability.

The mission does not require an arm, Orion can dock with the existing docking adapter at HST.
