He knows what he's talking about. Keep it simple and get it right this time.

CAPE CANAVERAL, FLA. — Just four years after President Bush announced his vision to send astronauts back to the moon and then on to Mars, legendary astronaut Buzz Aldrin is leading an effort to re-examine the whole idea — in particular, NASA's choice of rockets for the mission.

It is the latest sign that NASA's Constellation program — intended to replace the space shuttle after 2010 — is in trouble.

Concerned by reports that the Ares rockets and Orion crew capsule are beset by cost overruns, schedule delays and complex technical woes, Aldrin says he wants to create a panel of experts to make sure that Constellation is the right way to go.

"We need to stick with the mission but rethink some of the ways we implement it," said Aldrin, the second man to walk on the moon. "It doesn't pay to stick with a bad idea."
