On Tue, 4 Apr 2006 19:11:09 -0500, in a place far, far away, "Jon S.
Berndt" made the phosphor on my monitor glow in such
a way as to indicate that:

Don't know if this has been discussed before, but I noticed some time ago
that the LSAM will be discarded after it performs its duties. What are some
thoughts on a less wasteful approach:

1) An LSAM that travels between lunar orbit and lunar surface in one piece
(reusable),
2) A CEV that goes from ground-to-earth-orbit-and-back ONLY (crew taxi),
3) An Earth/Moon transfer vehicle that ONLY goes between earth orbit and
lunar orbit (reusable; stationed at ISS),
4) A fuel/cargo/resupply transfer vehicle that takes stuff anywhere.

Most of these things require fuel depots much farther out from LEO
than NASA apparently is willing to contemplate, or implement.
