For the second time this year, Nasa moved its moon rocket from the hangar out toward the launchpad on Friday in hopes of sending four astronauts on a lunar fly-around next month.

If the latest repairs work and everything else goes Nasa’s way, the Space Launch System could blast off as early as 1 April from Florida’s Kennedy Space Center. The Artemis II crew went into quarantine this week in Houston in preparation for blastoff.
