WATCH: NASA Press Conference - Scientists provide an update on the Artemis 1 mission

An update is provided by NASA scientists on the Artemis 1 mission after today's scrubbed launch.

NASA’s new moon rocket sprang another dangerous fuel leak Saturday, forcing launch controllers to call off their second attempt to send a crew capsule into lunar orbit with test dummies.

The first attempt earlier in the week was also marred by escaping hydrogen, but those leaks were elsewhere on the 322-foot rocket, the most powerful ever built by NASA.

NASA Administrator Bill Nelson said repair work could bump the launch into October.
