Jim - 9/2/2006 8:38 PMLSAM ascent stage only has batteries for 3 hrs and not much more O2. It receives most of its consumables (power, O2, water, etc) and heat rejection from the descent stage. This would be a big weight increase for the ascent stage and would ripple back to the descent stage.
Manel - 11/2/2006 1:56 PMMy question to VANILA is, if it has been considered the possible advantages of using the L1 point in the same conditions ? Perhaps the mission would need less days to complete ?
Manel - 12/2/2006 2:59 AMWhat are the numbers, delta V and time, for reaching the L1 point through an "type 8 trajectory" ?First braking at perilune at the far side and a final braking at L1Thank you in advance
Manel - 12/2/2006 9:56 AMClearly the use of the L2 point is the practical method for the next phase of lunar explorationOnly that needs an important enlargement in the crewed capacity of the LSAM´s ascent stage
Chris SF - 15/2/2006 6:36 AMWhen alternative is noted, does that mean there's a lack of confidence in the current future plans?

Manel - 12/2/2006 4:09 PMNot necessarily. The CEV needs only a delta V of 700 m/s vs 1.720 in the ESAS scenario (for TEI and possible plane change).
