Part of a set taken for the first STS-114 rollout, showing Discovery being brought into the VAB, stacked, and rolled out, so presumably in one of the hangers adjacent to the VAB. Last status update I could find - Jul 4 - said Endeavour was still in her OMM period; is this still the case, and if so would this location make sense? It'd certainly explain why she looks so dismantled... -- -Andrew Gray |

Yes, the RCS pods (aft) and forward RCS come off between flights. Also, perhaps the rudder/speedbrake is missing because of the speedbrake actuator problem identified a few months ago. Remember that the gears seemed to be in danger of jamming? |

Unfortunately, it's one of the many shuttle upgrades that never happened. :-( For a new vehicle, it would be nice to get rid of the hypergolics and go with something a lot more friendly, so hopefully you don't have to pull the RCS systems after every flight anymore.

(in article ): What could they use that isn't nasty, and _is_ reliable? AND has a reasonable ISP AND has a reasonable thrust? Aye, we've listed all the rubs haven't we? I've heard people bandy about ideas involving peroxide over a platinum catalyst - nasty enough, I guess, but nowhere near as nasty as hydrazine or nitrogen tetroxide. Or as powerful, I don't believe. I've also heard people discussing alcohol and LOX but that adds it's own problems - reliability and the weight involved to store sufficient cryogenic oxidizer among them. Well, all engineering is trade-offs. Just depends on how you prioritize the various design factors. -- "Fame may be fleeting but obscurity is forever." ~Anonymous "I believe as little as possible and know as much as I can." ~Todd Stuart Phillips www.angryherb.net |

Waht does anyone make of this excerpt from a Florida Today article
dated 18 August ( entitled No More Shuttle Flights in 2005): "Bill Gerstenmaier, the newly-appointed head of space operations at NASA, says the proposed changes have the side benefit of providing smoother turn-arounds between station construction missions further down the road. Under earlier plans, Atlantis would have flown back-to-back flights on a super-tight schedule. The new shuttle plan, which is yet to be formally approved by shuttle management, puts Atlantis in line to carry an especially heavy piece of the space station. It also sets a sequence of Discovery, Atlantis, Discovery rather than one in which vehicles might have had to fly back-to-back, a sequence that could have led to delays. "By being able to do this vehicle switch, that is going to make a more efficient schedule; that makes the impact not a very big impact," Gerstenmaier said." Where does Endeavour play into this? Is Endeavour undergoing the same upgrade and refit that Columbia did? Gene DiGennaro Baltimore, Md. |
