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. Snoopy will serve as the zero gravity indicator - meaning that he will begin to float inside the capsule once it reaches the space environment.
The crew aboard Artemis I may sound a little unusual, but they each serve a purpose. While the passenger list doesn't include any humans, it does have passengers: three mannequins and a plush Snoopy toy will ride in Orion. 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 (2.1 million kilometers). The team attempted the first plan again to warm up the line, but the leak reoccurred after they manually restarted the flow of liquid hydrogen. That troubleshooting plan was not successful. They stopped the flow of liquid hydrogen and proceeded to "close the valve used to fill and drain it, then increase pressure on a ground transfer line using helium to try to reseal it," according to NASA. The launch controllers warmed up the line in an attempt to get a tight seal and the flow of liquid hydrogen resumed before a leak reoccurred. It was a different leak than one that occurred ahead of the scrubbed launch on Monday. ET in the quick disconnect cavity that feeds the rocket with hydrogen in the engine section of the core stage. The liquid hydrogen leak was detected Saturday at 7:15 a.m. The first launch attempt, on Monday, was called off after several issues arose, including with a system meant to cool the rocket's engines ahead of liftoff and various leaks that sprung up as the rocket was being fueled.
It's the second time in a week that the space agency has been forced to halt the launch countdown in the face of technical issues. The leak prevented the launch team from being able to fill the liquid hydrogen tank despite trying various troubleshooting procedures. Liquid hydrogen is one of the propellants used in the rocket's large core stage. ET, three hours before the beginning of the launch window.Īrtemis I had been slated to take off Saturday afternoon, but those plans were scrubbed after team members discovered a liquid hydrogen leak that they spent the better part of the morning trying to resolve. I look at this as part of our space program, in which safety is the top of the list." "These teams have labored over that and that is the conclusion they came to. "We do not launch until we think it's right," Nelson said. NASA Administrator Bill Nelson reminded that the shuttle was sent back to the Vehicle Assembly Building 20 times before it launched. 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.įuture launch periods in September and October depend on what the team decides early next week.
