Planetary Resources, a mysterious organization whose investors include Google execs Larry Page and Eric Schmidt, Microsoft alum and astronaut Charles Simonyi, director James Cameron, "space visionary" Peter Diamandis, and Ross Perot, Jr., is planning to announce more details of the project this coming Tuesday. We'll be covering it, so we thought we'd give you a heads-up. It has something to do with space resources and exploration--its LinkedIn page says it "develops technologies and systems to enable low-cost commercial robotic exploration of the solar system," and cofounder Peter Diamandis has hinted at asteroid mining--but we don't know much more than that at the moment. Check in here on Tuesday (and, I mean, on Monday too, for other things) for the reveal.
