NASA is set to launch its newest rocket off on a test flight on Tuesday, but is delaying the launch because of minor problems. The Ares I-X rocket is set to lift off Tuesday morning, but forecasters are monitoring upper-level winds and clouds that could delay the experimental flight. The launch is already one and a half hours late because of extra time needed for the countdown and minor communication system trouble. This is the first step in NASA's effort to return astronauts to the moon. The flight will last two minutes. Parachutes will drop the first-stage booster into the Atlantic for recovery. The upper portion of the rocket - all fake parts - will fall uncontrolled into the ocean. The experimental launch comes as the White House is re-evaluating the human spaceflight program. --SPA
