Talk:Earth Departure Stage
From Wikipedia, the free encyclopedia
The second section (Other uses) seems pure speculation to me. Have we got any official NASA statement about these ideas ? Hektor 11:58, 1 April 2006 (UTC)

- Earth Departure Stage (Project Constellation) → Earth Departure Stage … Rationale: Only one article, and it is unlikley that there will be any others. There is no point for the distinction in parenthesis.

[edit] "Missions"?
A great deal of the information in this paragraph appears to be original research or incorrect. For the ISS resupply missions involving Orion, the Ares I booster is used. Since the EDS is only meant for the Ares V, the component can't be used for resupply missions. I believe the current plan for LEO rescues would be to send up another Orion with two crewmembers on an Ares I. NASA intends to make a six-person variant, so the rescue Orion would carry two people. They would dock, transfer the four-person crew, and return to Earth. I could see the possibility of using an EDS for rescues in lunar orbit, to perform a TLI manuever for the rescue vehicle, but I doubt if NASA will even plan for that contingency.
As for servicing satellites...this seems like pure speculation. I guess one can do this using an Ares V and replaced the LSAM with an unpressurized module containing the replacement components, then launched the crew up in an Ares I, docked, and used the EDS to send the configuration to the rendezvous point. But I've never heard this concept mentioned by NASA. The website for the James Webb Space Telescope indicates that, unlike Hubble, there are no plans to include "plug and play" modules that will be swapped out over the years. The JWST is scheduled to last only five to ten years. If the HST is any indication, the gyroscopes should last long enough for nine years without repair. I wouldn't call satellite repair a "certain use".
As for missions to Mars, NASA's ESAS report indicates that the Mars Transfer Vehicle will be assembled in orbit through multiple launches of the Ares V. Perhaps the author meant that a hollowed out version of the EDS could be used as a module for the Mars vehicle, but since its design is at such a very early stage (they don't even know how many assembly launches are required) this remark is pure speculation. It's also misleading; at first glance, I thought the author wrote that the Mars mission consisted of the same equipment as a lunar mission. Two years in an Orion spacecraft? Yikes.
At any rate, this entire paragraph needs to be heavily modified. Cardinal2 01:46, 29 November 2006 (UTC)
- Anonymous concurs. The part about polar orbit is especially strange. Launching CSM to some initial inclination, and then doing a rendezvous with a second launch from Florida so you can give the CSM enough fuel to do the inclination change just seems insane, nevermind what you would do with the thing once you've got it in polar orbit. --66.251.26.75 09:46, 10 December 2006 (UTC)
