Just a simple question. Can any currently planned commercial vehicle (with one or more launches) plan and complete a Hubble repair mission? I am looking forward to JWST as the next person but giving up such a still relevant instrument seems terrible to me. Any clues?
Hubble was outfitted with a passive LIDS interface and a set of laser retroreflectors during STS-125, so technically any of the commercial crew vehicles (Dragon, CST-100, Dream Chaser, and the Blue Origin vehicle) can rendezvous and dock with it.
Actually being able to perform a *useful* servicing mission is another matter. If any of the above vehicles can support standalone EVAs, that capability is certainly not being advertised yet. Only Dragon has any unpressurized cargo space for replacement instruments, and without a robotic arm, installation would be highly impractical.
In my opinion, an (as-yet unproposed) mission module would have to be developed and launched separately to provide said capabilities in order for any of these vehicles to perform a useful servicing mission.
