Starting this thread in hopes that we'll all have some detailed insight into the next generation of MSF engineering.
Noble goal, eh? ![]() Am I missing something here in terms of trade-offs? Seems unwieldy at best to have the arrays mounted to a sort of slip-ring assembly (with mast articulation) to maintain solar lock while the main body rotates. Likewise, seems as if an extensive--and in terms of power & volatile requirements/risk, expensive--ECS would be needed to avoid the temperature differential problem if the S/C is intended to maintain a continuous power-positive attitude during transit. Sure that there's a simple answer I've missed; would very much like to hear it! ![]() -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Here's a compressed version of the CEV demo video. (I have a higher res DVD quality version if anyone is interested)
-------------------- If Occam had heard my theory, things would be very different now.

How old is that video? I might be out of loop, but I thought the cryogenic engines used on the cargo LV will be RS-68, not SSMEs as said in the video.

They'll be RS-68B's, which are a modification of the RS-68 jointly being developed by NASA and the USAF (for Delta IV). Also, the core stage and EDS are 10 meters in diameter (like Saturn V), rather than 8 meters (like the Shuttle tank). Simon ![]() |
