NASA’s SLS moon rocket returns to launch pad for more testing
NASA’s first Space Launch System moon rocket rolled out to its launch pad early Monday at the Kennedy Space Center for another attempt later this month to fully load it with super-cold propellants, the culmination of a countdown rehearsal officials aim to complete before moving forward with launch later this summer.



NASA’s moon rocket rolls back to Vehicle Assembly Building for repairs
NASA rolled the giant new rocket for the Artemis 1 moon mission off the launch pad back inside the Vehicle Assembly Building before dawn Tuesday at the Kennedy Space Center. Officials hope to complete repairs in time to launch the Artemis 1 test flight to the moon no earlier than August, about two months later than previously scheduled.



NASA plans to roll first Artemis moon rocket back to hangar next week
NASA will move its first giant Space Launch System moon rocket off the launch pad and back to its hangar at the Kennedy Space Center as soon as next Tuesday, giving teams an opportunity to resolve several problems discovered during three attempts to load super-cold propellants into the launcher earlier this month.


Live coverage: Technical issues again prevent full loading of SLS tanks
NASA tried for the third time Thursday to load cryogenic liquid hydrogen and liquid oxygen propellants into the Space Launch System moon rocket at the Kennedy Space Center, after ground system issues cut short a countdown rehearsal on two occasions earlier this month. But a hydrogen leak in the connection between the launch platform and the core stage again forced officials to call off the countdown.
