<br />you can see that in thread's title there is the word "(possible)" and it ends with "?", not with "!"<br /><br />also, in my first post of this thread, I clearly use the "G" argument as a way to talk about a much more important question<br /><br />great part of the post is not about CLV solid-engine "G" (that may be like a liquid-engine rocket or not... we will see with real flights) but about the change of policy in space flights<br /><br />you may agree with me that the era of "normal peoples" and "scientists in space" born with SHUTTLE and with its low G, large cabin, 16-days missions, runway landing, etc.<br /><br />with the (liquid or solid engines) CEV/CLV, we will come back to the Gemini, Apollo, Vostok, Soyuz cold-war-moon-race era when, due to high-G-capsule and risky-missions, astronauts was captains, colonels, liutenants (of US Navy, USAF, Soviet Red Army, etc.) and a few "civils"<br /><br />all respectable and brave peoples, of course, that have made the story of spaceflights, but NOT scientists, researchers, engineers, etc.<br /><br />which kind of "science" these (very specialized pilots) may do on the moon?<br /><br />they will act as well-trained "human-robots" that will follow the given istructions with only a few changes<br /><br />also, the most depressing figures of the next 20 years moon exploration are the 15 weeks of TOTAL moon exploration time (the "net" time is less, since astronauts must sleep...) made with ONLY 48 non-scientists in TOTAL<br /><br />(around) 15 years without see NOTHING of moon, and, after, only (around) 5 years with "SO MUCH" exploration!<br /><br />it's like move a giant iceberg to New York only to have fresh icecubes for a Pepsi<br />
