The Artemis I Launch Team Is Ready For Another Test On Saturday

The start window opens at 2:17 p.m. ET and closes at 4:17 p.m. ET on Saturday. Weather conditions are currently 60 percent favorable during the launch window, according to weather officer Melody Lovin. He doesn’t expect the weather to be “presentable” for the launch. The Artemis I stack, which includes the Space Launch System rocket and the Orion spacecraft, continues to reside at Launchpad 39B at the Kennedy Space Center in Florida. While there’s no guarantee of a launch on Saturday, “we’re going to try,” Mike Sarafin, Artemis mission manager, said during a press conference Thursday afternoon. And while the launch team will take on a little more risk in the launch attempt, they are acceptable risks the team is comfortable with, Sarafin said. The Artemis I mission is unpaid. One of the areas where the team is taking more risks is in the preparation of the #3 engine, which contributed to the chafing of Monday’s launch attempt. Another is a crack in the foam of the intermediate stage core tank that could break off and hit part of the solid rocket booster, but the team believes the chances of that happening are very low, Sarafin said. It’s “a marginal increase in risk,” Sarafin said, but “we’re clearly ready to fly.” “We had a plan for the Aug. 29 launch attempt. It used the sensors to confirm the proper thermal regulation of the engines. We had trained that plan and then dealt with other issues,” Sarafin said. “We were off script in terms of normal tank operation and the team did a fantastic job managing a dangerous situation. One of the worst things you can do when you’re in a dangerous situation is to go even further off script.” After reviewing the data, the team has a plan to move forward. Work has been completed at the launch site to address two separate hydrogen leaks that occurred on Monday. The team also completed a risk assessment of the engine preparation issue and a foam crack that also appeared, according to NASA officials. 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 required to start the engine during launch. Engines must be thermally conditioned before running very cold propellant prior to start-up. To prevent the engines from experiencing temperature shocks, the launch controllers increase the pressure of the liquid hydrogen tank in the center stage to send some liquid hydrogen to the engines. This is known as “bleeding”. Now, the team has determined that it was a bad sensor that provided the reading. “We’ve had time to go back and look at the data and compare multiple data sources and do some independent analysis that confirmed it’s a bad sensor,” said John Honeycutt, SLS program manager at NASA’s Marshall Space Flight Center in Huntsville. , Alabama. “We’re getting good quality propellant through the engine.” On launch day, the team will ignore the bad sensor, said John Blevins, SLS chief engineer. The automated launch sequencer on the rocket controls temperature, pressure and other parameters. The bad sensor, which is not part of the sequencer, is not considered a flight instrument, Blevins said. The team plans to start the bleeding earlier in the countdown than it did on Monday. The countdown to the launch will continue on Saturday at 4:37 AM. ET during a scheduled hold. That’s when mission managers receive a weather update and decide whether the team should proceed with loading propellant onto the rocket. Bleeding is expected to occur around 8 am. ET, said Charlie Blackwell-Thompson, Artemis launch manager for NASA’s Earth System Exploration Program. There is no longer a need for a two-day countdown, as during the first launch attempt, “because many of the configurations required for launch are already in place,” according to NASA. NASA’s live coverage will begin at 5:45 AM. ET on its website and TV channel. “We have to show up, we have to be ready and we have to see what the day brings,” Sarafin said. If the mission launches on Saturday, it will travel around the moon and crash into the Pacific Ocean on October 11. There is still a backup chance for the Artemis I mission to launch on September 5 as well. The Artemis I mission is just the beginning of a program that will aim to return humans to the moon and eventually land crewed missions on Mars.
