Nasa turns to private companies to exploit the moon's resources

Nasa - building on successful partnerships with private companies to resupply the International Space Station - is now looking to private entrepreneurs to help exploit resources on the moon.

In its latest initiative, unveiled in late January, the US space agency is proposing private companies take advantage of Nasa's extensive know-how, its engineers and access to its installations to help design and build lunar robots.

But unlike Nasa's contracts with SpaceX and Orbital Sciences to deliver cargo to the ISS, the moon proposal - dubbed CATALYST (Cargo Transportation and Landing by Soft Touchdown) -would get no US government economic help.

Missions in the moon's orbit have revealed evidence of water and other interesting substances on the moon, said Jason Crusan, director of Nasa's advanced exploration systems.

"But to understand the extent and accessibility of these resources, we need to reach the surface and explore up close," he said.

"Commercial lunar landing capabilities could help prospect for and utilise these resources," permitting both commercial and research activities, he said.

Nasa official Greg Williams added: "As Nasa pursues an ambitious plan for humans to explore an asteroid and Mars, US industry will create opportunities for Nasa to advance new technologies on the moon."
