I need a list of Discovery missions from each of the competitions since the Discover Program commenced. Not including Lunar Prospector, for which I have plenty of information already. Can anybody help me out?
At a minimum I just need a list, I guess, but other information or sources would be very useful as well, as eventually I have to go there as well. Phil -------------------- ... because the Solar System ain't gonna map itself.

Well, Bob, yes, there's more to it, but that's the basics. But really, all you need to control is the plane of the orbit and the exact timing. And the Soviet Union was quite a big target. I confess I'm not sure if there was absolutely no correction ability, or a little bit, but it wasn't much if any. The point is, details aside, the procedure in question works for a limited area on the moon and that was well known.

Phil  Phil: So it was all done as a single-impulse trajectory, presumably with the ascent stage hard-engineered in such a way as to 'seek' a particular trajectory, wth the actual aiming done by time of launch and (perhaps) a rotation during ascent (as they couldn't be 100% sure of the alignment of the lander)? That fits with the philosophy behind their original satellite launchers, which used rotating bases (Soyuz uses the system to this day) and biased launch vehicles just like the V2 did. I always wondered why there were only two vernier motors in the illustrations of the ascent stage - if they only had to deal with a strictly limited range of inputs to the trajectory then that's explained! Really, very clever! Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

Yes, Bob, that's exactly how the Soviets did it. They set up landing sites where their probes had to only lift straight up, angle slightly to the right declination, and cut off the motor at a precisely pre-planned time, and if the lift-off time was calculated *precisely*, the sample return capsule would land on Soviet soil. There are only a few places on the Moon that are located in the right spot to do that, and Mare Fecundatitis and the surrounding highland plateau are a couple of the places where that is possible.
The Luna sample returns happened at landings on Mare Fecunditatis and the surrounding highland plateau. Coincidence? I think not. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
