NASA's latest attempt to fuel its huge moon rocket for a countdown test has been thwarted by a hazardous hydrogen leak
FILE -The NASA Artemis rocket with the Orion spacecraft aboard stands on pad 39B at the Kennedy Space Center in Cape Canaveral, Fla., March 18, 2022. After a series of equipment problems, NASA attempted an abbreviated fueling test of its mega moon rocket Thursday, April 14, 2022 at Florida's Kennedy Space Center. CAPE CANAVERAL, Fla.
This time, the launch team managed to load some super-cold liquid hydrogen and oxygen into the core stage of the 30-story Space Launch System rocket, but fell far short of the full amount. Liquid hydrogen is extremely hazardous, with officials noting that the systems had been checked for leaks prior to the test.
Two previous countdown attempts were marred by balky fans and a large hand-operated valve that workers mistakenly left closed at the pad last week.NASA had been targeting June for the launch debut of the 322-foot SLS rocket. The empty Orion capsule on top will be sent on a four- to six-week mission around the moon and back.
