NASA suspends launch of Artemis I mission until further notice

Cape Canaveral, Florida – The The National Center for Aeronautics and Space Administration (NASA in English) The launch of the Artemis I mission has been postponed until further notice Saturday’s scheduled takeoff was called off due to a second liquid hydrogen leak on the platform.

The spacecraft was to take off for an uncrewed test flight, which must go well before the astronauts can board.

However, at 11:17 AM ET, the countdown to the launch was halted and the launch was halted. NASA has indicated that next week they will have a clearer idea of ​​when to attempt the launch, but that won’t happen before the window closes next Tuesday, September 6.

The following windows are scheduled for mid-September and late October.

“The #Artemis I mission to the Moon has been postponed. Technical teams tried to fix a leak in the coupling between the main rocket and equipment that transfers liquid hydrogen to the rocket, but the attempts were unsuccessful,” NASA said in a tweet.

Mike SeraphineThe director of the Artemis missions explained during a press conference that the leak occurred due to excessive pressure in the fuel loading line, which in turn caused a large leak of liquid hydrogen that cannot be resolved in the launch pad.

“Due to an overpressure condition in the line, the seal of the quick disconnect vessel may be damaged. The leak occurred in this plug socket. During the launch attempt on Monday we saw a small leak but it was not the size of the leak we are trying to resolve today.”

Those working on the launch pad tried to stop the leak three times, but could not. They tried to increase the pressure in the line, but it didn’t work, as did the temperature balancing between the line and the bowl.”

Accordingly, NASA officials are considering two options: carry out the replacement of the case, or seals, on the launch pad, where they will be affected by inclement weather, or return the rocket to the assembly building, which can take several days, to carry out the operation in a controlled environment. Returning to the assembly building will allow them to recharge the missile batteries and the Orion capsule.

If NASA chooses to return the rocket to the assembly building, the launch will be delayed until the end of October.

“The SLS is a new vehicle and we are still learning how to set it up and drive it. We will fly when we are ready,” Serafin assured.

Because of how long they’ll have to wait for launch, NASA said they’ll have to review perishable items and whether they can stay on the launch pad for an extended period of time.

The first attempt, earlier in the week, was also marred by hydrogen leaks, but that attempt occurred elsewhere on the 98-meter (322-foot) rocket, the most powerful rocket NASA has ever made.

launch manager, Charlie Blackwell Thompsonand your team Try sealing Saturday’s leak as they did last time: by stopping and re-flowing supercooled liquid hydrogen in hopes of eliminating the open space around the supply line seal. They tried twice and also shot helium through the line, but the leak continued.

Blackwell Thompson finally stopped the countdown after three or four hours of futile efforts to load nearly one million gallons (3.8 million liters) of fuel.

The first countdown, on Monday, was called off due to an engine sensor malfunction and another fuel leak. The test flight must go well before the astronauts can get on board.

A Space Launch System (SLS) rocket will attempt to send the capsule around the moon and back. If successful, it would be the first capsule to fly to the moon since NASA’s Apollo program 50 years ago.

The $4.1 billion test flight is the first for NASA’s Artemis lunar exploration program, named after Apollo’s twin sister in Greek mythology.

The ship could carry astronauts on board in 2024 for a tour around the moon and attempt to land in 2025.
