The Artemis 2 moon rocket is leaving the launch pad at Florida's Kennedy Space Center, but not for its trip in the direction of the moon -- at least not yet. As was expected, the rocket is headed toward the Vehicle Assembly Building on site where NASA can address a helium blockage affecting the rocket's upper stage.

The space agency, which had announced an original launch window beginning March 6 for the test flight's liftoff, has said the repair could delay things for a month or more. This is to be the first crewed moon mission in more than 50 years. Four amateur radio operators are among the 34 volunteer observers around the world chosen recently to passively track radio waves transmitted during the mission.
