According to NASA, the teams ended on Monday because they had to deal with various problems that started on Sunday. They included an anti-flammable shielding gas, fans that handle hazardous gases, a not-quite-cold cryogenic propellant, and a “glare breach” software alert. NASA teams from all over the United States are taking part in this two-day, final leg of the test, so that the rocket, called the Space Launch System (SLS), can take off. To reach thousands of miles across the moon and back, the future crew capsule called the Orion needs a huge boost to successfully complete the body’s Artemis 1 mission. More than 700,000 gallons of cold liquid propellant will be needed to operate the moon. All this material must be carefully controlled. The propulsion of the propulsion system into the SLS rocket and the drainage of the spacecraft in the event of a sudden cancellation of the last second launch must be meticulously evaluated by NASA teams. If Artemis 1 is successful, the organization will be one step closer to returning the first humans to the Moon after the Apollo program.
What went wrong with the Artemis 1 wet wedding dress rehearsal?
Monday’s wet-dress rehearsal was originally scheduled for Sunday, April 3, after NASA staff received a “station call” on Friday, April 1. hazardous gases. The wet dress rehearsal was then moved to Monday, to begin after a pre-tank briefing. But then there was a problem with the supplier of nitrogen gas, a substance that helps keep the inside of the SLS non-flammable during tank work. But once that was resolved, SLS software found an “anti-glare breach,” according to Charlie Blackwell-Thompson, director of launch for NASA’s Exploration Ground Systems program at the Kennedy Space Center, who spoke at a conference call Tuesday (April 5th). ) for the liquid rehearsal. This built-in protection went out because some liquid oxygen booster had become too hot and the substance had to stay very cold for it to work properly. Eventually, the team decided that the staff had to go to the rocket to assess the issue, and by then, it was too late. But the wet general rehearsal had its triumphs. For example, the team was able to control the Orion start-up countdown configuration and control the Orion launch day communication, according to Blackwell-Thompson.

What is Artemis 1?
Artemis 1 is the first rocket flight for the Artemis program, which is NASA’s push to return manned missions to the lunar environment. When the 322-foot SLS finally flies into the Caribbean sky from NASA’s Kennedy Space Center on Cape Canaveral, Florida, the powerful launch vehicle will produce 8.8 million pounds of thrust at takeoff, displaying 70 metric tons (77 tons). Lifting capacity, take just 90 seconds to “reach the period of greatest atmospheric power” and send the unpaid Orion capsule on a journey of 280,000 miles to the moon with impressive momentum. Artemis 1 will be a four- to six-week mission, taking the Orion farther away than any manned spacecraft to date and ending with the Orion recording more time in space than any other spacecraft without mooring, according to NASA. NASA had previously targeted the launch of Artemis 1 for February 2022.
What is a wet dress rehearsal?
During the wet dress rehearsal, the teams spend two days practicing the cryogenic propellant refueling process. They also evaluate the tank removal process, which removes the propellant from the SLS if the spray is cleaned. NASA will receive a specific launch date for Artemis 1 as soon as the wet dress rehearsal data finally shows that everything is fine.
When is the next wet dress rehearsal?
The next wet dress rehearsal will take place after the launch of Axiom-1 (currently scheduled for Friday, April 8), according to Mike Seraphin, director of the Artemis 1 mission to NASA headquarters. An exact date has not yet been scheduled.
