Artemis lunar rocket achieves notable achievements despite problems in key pre-launch tests

The fourth attempt in the final pre-launch test began on Saturday, and the missile tanks were full on Monday.

The key test, known as wet wear training, simulates each launch phase of the rocket without leaving the launch pad at the Kennedy Space Center in Florida.

This process includes loading the supercooled thrusters, running a full countdown to the simulated launch, resetting the countdown clock, and emptying the missile canister.

The results of the wetsuit training will determine when Artemis I will begin his mission beyond the moon and return to Earth. The mission will kick off NASA’s Artemis program, which is expected to return humans to the moon and land the first woman and person of color on the moon by 2025.

The first three test attempts in April were unsuccessful due to multiple leaks and ended before the missile was fully fueled. Those bugs have now been fixed, NASA said.

The NASA team carried the 322-foot (98 m) Artemis I rocket stack, including the Space Launch System and Orion spacecraft, to the launch pad at Kennedy Space Center in Florida on June 6.

Wet test procedure

Rehearsals kicked off Saturday at 5pm ET with a “call to the season” — a two-day countdown to when all mission-related teams arrive at their consoles and report they’re ready to begin testing.

The weekend’s preparations have the Artemis team ready to begin loading the thrusters into the rocket’s core and upper stage on Monday morning.

The tanks were suspended Monday morning due to an identified problem with nitrogen backup supplies. The release team replaced the valve that was causing the problem. To ensure the backup source works as expected, it has been replaced with the primary test source.

Comments were canceled at 9:28AM ET. Liquid oxygen is cooled to minus 297 degrees Fahrenheit (minus 182 degrees Celsius), and liquid hydrogen is used to fill the center stage before entering the rocket’s upper stage. The opening was visible from the missile throughout the operation.

When a few issues occurred after 2:00pm ET, the base stage was almost completely filled, while the team was filling up the upper stage.

The team detected a hydrogen leak in the central stage rapid separation line.Their first choice didn’t work out, they learned Option to turn off leaks.

Something from the glow pile, the excess liquid hydrogen in the rocket burned by the propane flame, caused a small fire in the grass towards a dirt road. The team monitored the grass fire and expected it to start once it reached the dirt road.

The test exceeded the planned 30-minute wait time, which was extended as engineers tried to fix the hydrogen leak.

According to a tweet from NASA’s Earth Exploration System, the Artemis team decided to continue the countdown, while covering up the hydrogen leak, “to continue our wetsuit trials today.”

The 10-minute countdown starts at 7:28pm.

There are usually two countdowns during rehearsals. First, team members typically do a 33-second countdown to launch, then break the cycle. The clock is reset, and the countdown starts again and runs until about nine seconds before the launch occurs.

Monday’s brief countdown ended early, with 29 seconds remaining on the countdown clock. The computer science of the SLS missile led to the hack, but the exact science was not shared. Before the countdown, the team said that if the computers involved in the countdown detected a hydrogen leak, it could be similar to a check engine light that forces the countdown to stop prematurely.

After the countdown stopped, the Artemis team worked hard to ensure the safety of the vehicle.

“It’s definitely a good day for us, such as putting the entire rocket in Tank and pass the countdown.

The next steps, she said, will be to assess all the data collected from the test, including the questions, and develop a plan for moving forward.

Blackwell-Thompson said previous wet-cloth training attempts had accomplished many goals in preparation for the missile launch.

With a long history of exhaustively testing new systems before launch, the Artemis team faced a similar experience to the Apollo and Space Shuttle teams, including multiple test attempts and delays.

The mission team is looking for possible launch windows to send Artemis 1 on a trip to the moon in late summer: Aug. 23-29 and Sept. 2-6. beyond.
