Taken in context in 1972, very impressive, it could be our discussion today (and he better have a good pair of boxing gloves) ;-) Ref: Bulletin of the Atomic Scientist (December, 1972) pp. 32-38. "The first thing we saw on in the Apollo 11 samples was that the soil was enriched in about a dozen "meteoritic" elements relative to the rocks. The amount corresponded to an admixture of about 1.5 to 2.0 per cent meteoritic material. Because the elements ocurred in essentially solar proportions we could tell that this material was very primitive, similar to carbonaceous chondrites. And this is still true four missions later..." ""I have always been rather critical of the manned space program, at first because I considered it an extravaganza and later because it undercut and weakened our unmanned lunar and planetary programs...But now that the money has been spent...Let us face it, manned Lunar exploration is probably a one-time adventure for mankind. After the Apollo program ends, I think it will take many decades or centuries before mankind attempts another manned lunar program. There is a lot of fundamental information hidden in the lunar rocks, and as with the meteorites, it will take a sustained effort over centuries to extract all this information. So we are really gathering samples for future generations and the cost of the lunar missions has to be judged from this point of view. Therefore it is an opportunity to carry out these missions while we still have trained astronauts, technicians, and engineers, why not? The ost is something like 50 cents for every man, woman and child in the country..." I opposed asteroid missions because asteroids are probably the only celestial bodies [sic.] from which samples are delivered free of charge to our door step. It would be quite embarrassing if an expensive mission were launched to an asteroid and brought back samples a few years later esentially identical to meteorites that have been sitting on museum shelves for many years. We would have spent all this money to get material that is already on hand. I would concede one point, namely, that we probably get meteorites only from a small fraction of the asteroid population, maybe 10 percent, maybe less. More than 90 per cent of the asteroids do not communicarte with us. Among those are some oddballs which are quite different from the rest. If future work shows that some of these asteroids are keys to the mysteries of the solar system, then one can make a case for a mission to such an asteroid. Kindest wishes Doug PS Next time we go - and we will - it will be with less brawn but at least as much brains! Got to love the last quote in light of the DAWN mission at Vesta today. -----Original Message----- From: MexicoDoug <mexicodoug at aim.com> To: karmaka at email.de; Meteorite-list at meteoritecentral.com Sent: Thu, Jul 28, 2011 5:39 pm Subject: Re: [meteorite-list] Who invented the phrase 'the poor man's space probe'? ... nothing but a 'poor man's space probe' launched unceremoniously somewhere in the asteroidal belt sometime during the last two billion years [sic.] ...? ? 1960 - Dr. Edward Anders?
