NASA will not pursue a launch of Artemis I for the remainder of the launch period, which ends on Tuesday, according to an update from the agency after a second scrubbed launch attempt Saturday.
NASA Administrator Bill Nelson reminded that the shuttle was sent back to the Vehicle Assembly Building 20 times before it launched.
The liquid hydrogen leak was detected Saturday at 7:15 a.m. ET in the quick disconnect cavity that feeds the rocket with hydrogen in the engine section of the core stage. It was a different leak than one that occurred ahead of the scrubbed launch on Monday. There was a 60% chance of favorable weather conditions for the launch, according to weather officer Melody Lovin.
Both were considered to be acceptable risks heading into the launch countdown, according to Mike Sarafin, Artemis mission manager. The team has since determined it was a bad sensor providing the reading -- they plan to ignore the faulty sensor moving forward, according to John Blevins, Space Launch Systems chief engineer.Once Artemis I launches, Orion's journey will last 37 days as it travels to the moon, loops around it and returns to Earth -- traveling a total of 1.3 million miles .
The mannequins, named Commander Moonikin Campos, Helga and Zohar, will measure the deep space radiation future crews could experience and test out new suit and shielding technology. A biology experiment carrying seeds, algae, fungi and yeast is also tucked inside Orion to measure how life reacts to this radiation as well.
