US space agency Nasa has aborted its launch of the Artemis Moon rocket for a second time in a week after controllers discovered a leak in its hydrogen tank. Engineers couldn't repair the issue in time to allow the launch to go ahead this weekend and will now look to Monday next week for a possible launch. The first launch was postponed after controllers struggled to get an engine on the 100m-tall vehicle cooled down to its correct operating temperature. The maiden flight, part of Nasa's Artemis programme, is just a demonstration with no one on board. But ever more complex missions are planned for the future that will see people live on the lunar surface for weeks at a time. Please subscribe HERE #Nasa #Artemis #BBCNews
