SPACE FLIGHT 2011 (interactive discussion)

[backtrax]

The Saturn 5 was the single most impressive launch vehicle ever made. What did we learn? Was that knowledge gained preserved?
A few years back "Experts" claimed that it would not be possible to do that again, the some of the methods used were "Lost"! Utter disbelief to have heard that.
Chemical propusion has its uses. (And limitations, and costs) I suppose its too much to hope for, that some genius out there is on the verge of discovering Dark Matter repulsion/attraction work-around that would give us a seemingly "Antigravity" device, lol.
