NASA reschedules Artemis I launch for Saturday, Sept. 3

NASA will try again Saturday to launch its new moon rocket on a test flight after engine trouble halted the first countdown this week.

Managers said Tuesday they are changing fueling procedures to deal with the issue. A bad sensor also could be to blame for Monday's scrapped launch, they noted.

The 322-foot (98-meter) rocket — the most powerful ever built by NASA — remains on its pad at Kennedy Space Center with an empty crew capsule on top.
