NASA’s Moon Plans Shift into High Gear

NASA is set to begin rolling out the results of a landmark space exploration architecture study that calls for building an Apollo-like astronaut capsule and conducting up to six lunar sorties per year using rocket hardware derived from the space shuttle.
Sixty days in the making, the Exploration Systems Architecture Study will go a long way toward defining the approach and the hardware NASA will use to return astronauts to the Moon by 2020, and eventually go on to Mars.
