But of course, in a recovered asteroid, the real value is probably in the water. A 14,000 ton carbonaceous asteroid could have 1000 tons of water in it. Here we are worried not about what we could sell it for on Earth, but what it would cost to get that much water into space or recover it from the Moon.

According to coolquiz.com, the commercial value of the substances in the average human body is $4.50. The average adult man has a mass of about 80 kg; the average adult woman, about 60 kg. So, the average adult person is about 70 kg. This indicates that the average adult is worth about $64/MT, nearly two-thirds the commercial value of a chondrite according to Jeff's calculation.

Of the major groups of carbonaceous, ordinary, and enstatite chondrites, H chondrites are worth the most... I get $162/ton ($80 of which is Pt, $25 Pd, $24 Ir, $12 Au, $10 Os, $8 Rh, $3 Ru). I would put our 15-m radius C-type asteroid at around $1.5M worth of precious metals. Can somebody else reproduce $15B, which is 10000 x what I got? I used the following prices in $/kg:$2,733 RU $38,585 RH $23,441 PD $868 AG $3,500 RE $12,219 OS $32,154 IR $49,486 PT $50,836 AUH chondrites have the following concentrations in kg/ton (which is the same as mg/g)RU 0.00111 RH 0.000207 PD 0.0011 AG 0.0000841 RE 0.00008 OS 0.00082 IR 0.00074 PT 0.0016 AU 0.00023And our 15-m radius C asteroid with density=1 g/cc weighs 14000 metric tons.So Pt in this asteroid is 49486 $/kg * 0.0016 Kg/ton * 14000 tons = $1,100,000Did I mess something up? I'm tired, so maybe I did something wrong.

Of course there is nopossible escape from this living death, but movies need happy endingsso our heroes always make it home to their Honey. Mining asteroids seems a bit far-fetched to me.But ask a question or make a comment on the m-list and someone opensthe door to knowledge for you. Just walk through.Thanks to Randy Korotev, I know that "OC's may contain Pt at ore-gradeconcentrates of 1ppm."But really, how concentrated is that I wondered, ever the sceptic. Two seconds research informed me that Platinum is an extremely rare metal, occurring at a concentration of only 0.005 ppm in the Earth's crust.Looking deeper into the topic (research is like mining, just keep digging and you'll always find your bone) ..."Platinum exists in higher abundances on the Moon and in meteorites.Correspondingly, platinum is found in slightly higher abundances atsites of bolide impact on the Earth that are associated with resultingpost-impact volcanism, and can be mined economically; the Sudbury Basin is one such example." And... "From 1889 to 1960, the meter was defined as the length of a platinum-iridium (90:10) alloy bar, known as the International Prototype Meter bar. The previous bar was made of platinum in 1799.The International Prototype Kilogram remains defined by a cylinder ofthe same platinum-iridium alloy made in 1879."Those two paragraphs were uncovered from http://en.wikipedia.org/wiki/PlatinumSterling Webb's ever astute comments and links gave me leads and infoso that with a little follow-up I've also learned -- the total mass of all asteroids equals about 4% of our Moon's mass.(I had always thought the sum was equal to a 'broken' or 'aborted' planet the size of Mars or larger).- C-type asteroids are carbonaceous and the most common. Consisting of clay and silicate rocks they exist furthest from the Sun in the outer Belt and are the least altered by heat. They may consist of up to 22%water. - S-type 'silaceous' asteroids are primarily stony materials and nickle-iron and are found in the inner belt.- M-type asteroids are mostly nickle-iron and range in the middle region.One linked article allows that "because C-type asteroids are expectedto have water they will be targeted first, the hydrogen and oxygen split to create fuel". (H-m-m-m-m-m, but 'closer' asteroids is 'better' asteroids).Most importantly, is mining platinum on asteroids and delivering it toEarth like so many storks bringing babies from outer space cost effective?It was estimated that a single 30m asteroid might yield $25-50 billionworth of Pt, more or less 40,000 to 80,000kg at 'today's prices'. The world's total Pt output was 192,000kg in 2010.Sterling) we learn, "...the real doubt over this sort of enterprise isFrom the 'Economist' article link (BTW - my favorite magazine,not the supply, but the demand. Platinum, iridium and the rest are expensive precisely because they are rare. Make them common, by digging them out of the heart of a shattered planet, and they willbecome cheap. The most important members of the team, then, may not be the entrepreneurs and venture capitalists who put up the drive and themoney, nor the engineers who build the hardware that makes it all possible, but the economists who try to work out the effect on the price of platinum when a mountain of the stuff arrives from outer space."..... leaving me calculating the 'present value' of all this preciousmetal in 'Bitcoins' :>) Happy week-end.
