More than half a century after astronauts last left the lunar surface, NASA is preparing to send a crew of four back to the moon on a fly-by mission that will sling them around the far side.

NASA said Tuesday it will now target a March launch of its new moon rocket after running into exasperating fuel leaks during a make-or-break test a day earlier.

The planned Artemis II crew includes three U.S. astronauts - ⁠Reid Wiseman, Victor Glover and Christina Koch - and ​a Canadian astronaut, Jeremy Hansen.
