![]() Now, the team has determined it was a bad sensor providing the reading. To prevent the engines from experiencing any temperature shocks, the launch controllers increase the pressure of the core stage liquid hydrogen tank to send a little bit of the liquid hydrogen to the engines. The engines need to be thermally conditioned before super-cold propellant flows through them before liftoff. On Monday, a sensor on one of the rocket’s four RS-25 engines, identified as engine #3, reflected that the engine could not reach the proper temperature range that is required for the engine to start at liftoff. ![]() The team has also completed a risk assessment of the engine conditioning issue and a foam crack that also cropped up, according to NASA officials. Work has been completed at the launchpad to address two different hydrogen leaks that occurred Monday. One of the worst things that you can do when you find yourself in a hazardous condition is just go even further off script.”Īfter reviewing the data, the team has a plan for moving forward. “We were off the script in terms of the normal tanking operation, and the team did a fantastic job working through the managing of a hazardous condition. We had trained that plan, and then we ran into other issues,” Sarafin said. It used the sensors to help confirm the proper thermal conditioning of the engines. “We had a plan going into the August 29th launch attempt. Meet Commander Moonikin Campos, the mannequin going farther than any astronaut Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration. ![]() Artemis I will be an uncrewed test flight of the Orion spacecraft and Space Launch System rocket as an integrated system ahead of crewed flights to the Moon. Technicians checked connectivity and performed fit checks on his flight suit to ensure he is ready for flight aboard the Artemis flight test. Moonikin "Campos" will be installed into the Orion crew module. 9, 2021, inside the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. Teams from Johnson Space Center, Exploration Ground Systems, and Jacobs TOSC conduct final inspections of Moonikin "Campos" on Nov. It’s “a marginal increase in risk,” Sarafin said, but “we are clearly ready to fly.” ![]() Another is a crack in the foam of the core stage intertank which could break apart and hit part of the solid rocket booster, but the team feels that the chances of that are very low, Sarafin said. One of the areas where the team is assuming more risk is with the conditioning of engine #3, which contributed to the scrub of Monday’s launch attempt. And while the launch team will assume a little more risk heading into the launch attempt, they are acceptable risks that the team is comfortable with, Sarafin said. While there is no guarantee of a launch on Saturday, “we’re going to try,” said Mike Sarafin, Artemis mission manager, during a news conference Thursday evening. The Artemis I stack, which includes the Space Launch System rocket and Orion spacecraft, continues to sit on Launchpad 39B at Kennedy Space Center in Florida. She doesn’t expect weather to be a “showstopper” for the launch. Currently, weather conditions are 60% favorable during the launch window, according to weather officer Melody Lovin. The Artemis I launch team is gearing up for another countdown that will begin early Saturday morning after a range of issues prevented liftoff on Monday.
