(...) astronaut geologists like Jack Schmitt Apollo 17 astronaut (...)?
He was the only scientist who ever walked on the Moon, but Harold C. Urey (Nobel Prize in chemistry, 1934) had nasty things to say about the NASA, geologists and astronauts.
"(...) Urey publicly criticized NASA for lacking first-rate scientists (...). (...) he challenged the space agency for not selecting astronauts with science backgrounds (...). (
Exploring Space -- Voyages in the Solar System and Beyond, W. E. Burroughs, Random House, New York, 1990, p. 97n.)
"He [insisted] that the [Apollo] program ought to have been shaped primarily by the requirements of scientific investigation --by its potential science returns-- not by the simple need to land astronauts on the lunar surface to go cavorting around for the sake of politics." (p. 166)
"(...) He didn't think much of what [geologists] did (...).
" 'You have turned heavily to geologists', he was to complain (...). 'I know of some good, brilliant geologists, but mostly they are a second rate lot. This is known in university circles very well. I do not agree with Jim Conant who as president of Harvard abolished the Geology Department on these grounds, but we all know that geology attracts the less brilliant type of scientists. After all, it is [merely] descriptive, and very often they do not learn more than the most elementary things about chemistry and physics. The Geological Survey is filled with people of this kind,' Urey noted sourly. He would nevertheless see the day when the geologists came to constitute the vanguard of those who conducted the most important analyses of the terrestrial planets and (..) of moons (...).
"Nor was Urey impressed by the professional qualities of the astronauts themselves. Of the astronaut selection process, he complained that more emphasis ought to have been placed on scientific expertise and less on sex appeal, but given the acknowledged purpose of the Apollo program --to simply get people there -- 'any man or woman with an attractive personality would do,' Urey said contemptuously."
