Less than three weeks after publicly unveiling its asteroid mining plans, the billionaire-backed firm Planetary Resources has received thousands of job applications, officials said.

On April 24, the company announced that it was looking to hire engineers who would help design and build a fleet of asteroid-mining robotic probes. The resulting resume deluge was so intense that Planetary Resources has turned off the spigot.

“We have received over 2,000 applications since our April 24th press event, and we are not currently accepting applications for full-time employees, summer internships or student co-ops,” reads an update on the company’s website. “In the near future, we will be seeking applications from students for Fall 2012 co-ops.”

Planetary Resources was founded by private spaceflight pioneers Peter Diamandis and Eric Anderson. Its investors include Google execs Larry Page and Eric Schmidt, who are worth more than $20 billion combined. Filmmaker and adventurer James Cameron, former NASA astronaut Tom Jones and Massachusetts Institute of Technology planetary scientist Sara Seager are advisers.

The company plans to mine near-Earth asteroids for platinum-group metals and water. Water can be broken into its constituent hydrogen and oxygen, the chief components of rocket fuel. The company hopes its efforts will lead to the establishment of in-space “gas stations” that allow many spacecraft to refuel cheaply and efficiently.

Swarms of low-cost unmanned spacecraft would extract resources from asteroids in deep space. Planetary Resources officials have said they hope to identify some promising targets within the decade, though actual mining activities would come later.

Planetary Resources currently employs about two dozen engineers, officials said at the April 24 unveiling. Diamandis said the company hopes to stay relatively small, so it can move quickly and do what it can to keep costs down.
