Space, it has been said, is big. Really big.
But big enough for two companies that want to mine near-Earth asteroids?
A venture announced Tuesday in California hopes so.
Deep Space Industries says it wants to start sending miniature scout probes, dubbed "Fireflies," on one-way missions to near-Earth asteroids as soon as 2015. Larger probes, "Dragonflies," that will bring back 50- to 100-pound samples from prospective targets could be on their way by 2016, company CEO David Gump told reporters.
