Actually, I believe the latest revised HST plan doesn't use the OMV. The problem is to get the HST up to the highest altitude possible, given that we've got a solar maximum (and hence an atmospheric-drag maximum) coming up. There was talk of using the OMV for that, but I think they've decided that they can coax the shuttle up to a suitable altitude if they try hard. -- Mars in 1980s: USSR, 2 tries, | Henry Spencer at U of Toronto Zoology 2 failures; USA, 0 tries. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu

Curious. How does one "coax the shuttle up to a suitable altitude?"

How does one "coax the shuttle up to a suitable altitude?" I'm not up on the details myself, but some of it is obvious: minimize secondary payloads, minimize consumables, pick the most efficient trajectory possible, pick a favorable phase of the Moon... :-) -- Mars in 1980s: USSR, 2 tries, | Henry Spencer at U of Toronto Zoology 2 failures; USA, 0 tries. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu
