NASA wants permanent moon base

HOUSTON, Texas (CNN) — NASA’s plans for returning people to the moon — an objective called for by President Bush in 2004 — includes establishing a permanent outpost that would be used to prepare for a manned trip to Mars.

The moon base would be at either the north or south pole of the moon, NASA Deputy Administrator Shana Dale said during a news conference Monday at the Johnson Space Center in Houston.

Increased sunlight at the poles would allow better use of solar energy to power the outpost, she said.

NASA’s lunar architecture team decided it would be better to establish a base than to conduct individual missions to the moon, as in the Apollo program of the 1960s and 1970s, she said.

Team scientists believe astronauts could use the moon’s natural resources to maintain the outpost, and could use the base to prepare for the trip to Mars, an objective also set forth by Bush.
