A billionaire-backed asteroid-mining company aims to start putting its big plans into action soon, launching its first hardware into space by this time next year.
Planetary Resources, which counts Google execs Larry Page and Eric Schmidt among its investors, plans to loft a set of tiny "cubesats" to Earth orbit in early 2014, to test out gear for its first line of asteroid-prospecting spacecraft.
"Our belief and our philosophy is that the best test bed is space itself," Chris Voorhees, Planetary Resources' vice president of spacecraft development, said Wednesday during a Google+ Hangout. [Planetary Resources' Asteroid-Mining Plans]
"Despite the fact that we're a deep-space company, we're going to use Earth orbit as much as possible," Voorhees added. "For us, it's a valuable learning experience, and that's what we plan on doing one year hence."
The test bed slated for launch in 2014 is made up of three "cubesats," measuring 12 inches long by 4 inches wide by 4 inches tall (30 by 10 by 10 centimeters), company officials said. The Arkyd-3 satellite will test out technologies for Planetary Resources' Arkyd-100 scouts, which the firm hopes to launch to low-Earth orbit on asteroid-hunting missions in 2015.
The Arkyd-3 "is the testbed manifestation of our Arkyd-100 spacecraft. It just happens to be flying," Voorhees said.
A series of other robotic probes beyond the 33-pound (15-kilogram) Arkyd-100 will investigate near-Earth asteroids up close, eventually mining suitable ones for resources such as water and precious metals. Water is the key focus at first, because it is the key enabler of off-Earth living, Planetary Resources officials said.
Water can keep astronauts hydrated, and serve as a shield against dangerous radiation. Split into its constituent hydrogen and oxygen, it can also provide breathable air and rocket fuel, allowing voyaging spaceships to fill up on the go.
Sourcing water in space will make space travel much cheaper and more efficient, Planetary Resources President Chris Lewicki said. He noted that it currently costs about $10,000 to launch 1 liter (0.26 gallons) of water to low-Earth orbit.
"Water is the gateway drug of space. It's the enabler — in a good way, though," Lewicki said.
Planetary Resources held Wednesday's Google+ Hangout partly to mark the one-year anniversary of the company's public unveiling. After Planetary Resources announced its existence and intentions last year, another asteroid-mining firm called Deep Space Industries made its presence known as well.
Both companies hope their activities help spur humanity's push out into the solar system, officials have said.
