Former astronaut Buzz Aldrin supports many of the principles the administration has called for regarding NASA and he’s given some thought on how to move the nation forward in space.
Mr. Aldrin identifies a number of important ideas, but IMHO the three most important goals he calls for include 1) an increased presence and use of commercial space, 2) manned missions beyond low earth orbit, and 3) unlocking the economic/scientific promise of space.
Included in his proposal would be an Executive Order leading to a man-rated EELV. Of course just such a gap-filler this has been considered (by many) and rejected (by NASA) in the past as not meeting their needs.
Now the needs have changed and massive programmatic whipsawing is occurring. The challenge will be in generating administration, NASA, and Congressional enthusiasm for a man-rated EELV.
BTW, haven’t we pretty fully explored low earth orbit?
