The asteroid-mining industry has taken a step closer to becoming an actual thing, with the successful deployment of Planetary Resources' Arkyd 3 Reflight (A3R) spacecraft from the International Space Station Wednesday night. The A3R's three-month mission will be used to test and validate some basic technologies that the company hopes to incorporate in future spacecraft that will prospect near-Earth asteroids for potentially valuable resources.
"Our philosophy is to test often, and if possible, to test in space," says Planetary Resources president and chief engineer Chris Lewicki. "The A3R is the most sophisticated, yet cost-effective, test demonstration spacecraft ever built."
The small craft was sent to the ISS aboard a SpaceX Falcon 9 resupply mission in April. On Wednesday (July 15), it was sent out the Kibo airlock to begin checking out its avionics, control systems and software, among other systems. It will be followed up by the Arkyd-6 (A6), another demonstrator set to launch later this year. The larger A6 will check out next-generation attitude control, power and communication systems, as well as the sensors that will be used to detect resources with good potential for mining.
When I was a kid I found a science fiction novel on the shelves in a cabin in Glacier National Park entitled, "Assignment in Space with Rip Foster," in which the heroes try to steer an asteroid of pure thorium back to Earth orbit. The cover of the book was hokey, but the story was one of the better "science" science fiction stories I've read, in the sense that there were no magical technologies to make everything easy to accomplish; there was just plain old rocketry and physics. But as interesting as the concept of asteroid mining is, wouldn't the fabulous costs and potential to crash commodities markets once you brought something back to Earth defeat the profit motive?

Actually, this link http://www.indexmundi.com/en/commodities/minerals/platinum-group_metals/platinum-group_metals_t5.html [indexmundi.com] says that the yearly production of platinum is about 200 tonnes.
500 tonnes is the whole platinum group. (200 platinum, 200 palladium, 100 everything else).
Nitpicking aside, 200 or 500 tonnes is huge for a science or test mission, but tiny for an actual mining operation.
