Was your work on the optical side of things, or mechanical? Was the Hubble work done in CodeV or Zemax or something else? With modern ceramics and technological developments what changes do you think would be made if Hubble was made today?

Cool. Can you briefly discuss some of the materials concerns that you have to consider when fabricating electromechanical structures for spaceflight? Were they Invar or something else? Are the motors radiation hardened?

Thank you for your answers, this AMA is really cool for a junior engineer like myself. What is the power requirement on one of those gyros? Were they constantly in operation, or only when a correction was needed? If they were constantly going, how on earth did you guys avoid abrasion at the axles?

How is required aperture decided or computed when designing a new space telescope system? Aberrations don't scale linearly, so it has to be a first-principles approach? Or is it a scaling/re-optimization of the optical prescription?

Can you give a little bit of rundown on your involvement with Hubble? Were you in it from the beginning? At Danbury? A launch engineer? Maintenance? I'd like to ask a lot more questions but I don't know enough about you!
