Today, NASA called off the last major test of its Space Launch System (SLS) rocket after pressurization problems prevented technicians from safely loading propellants into the rocket. The test, known as a wet dress rehearsal, has been postponed until Monday, April 4, at the earliest, NASA announced in a statement. a blog post Artemis I live.
“The crews have decided to scrub tanking operations for the wet dress rehearsal due to the loss of ability to pressurize the mobile launcher,” NASA explained. Some fans on the mobile launcher, the platform that supports the rocket until launch, were unable to maintain positive pressure, which is crucial for warding off dangerous gases. As a result, NASA technicians were unable to “proceed safely” with the fueling process.
For safety, we have stopped the #Sagebrush I did a wet dress rehearsal. The teams are meeting now to assess the next steps. We look at Monday April 4th as the next opportunity to resume operations and will hold a press conference later today. Check here for updates. https://t.co/pweviGRjwg

This type of dress rehearsal gets its “wet” label as it’s essentially a walkthrough of all the procedures NASA will have to go through when the first real SLS launch takes place, including filling the 322-foot rocket. with 700,000 gallons of propellant. . in a Press conference on Sunday night, NASA said its team is currently on the launch pad trying to fix the problem. The agency says it is on track to resume the wet dress rehearsal tomorrow.
The test originally started on April 1. at the Kennedy Space Center in Florida and was supposed to end on Sunday. NASA ran into bad weather on Saturday night, as lightning struck the towers around the SLS launch pad. Jeremy Parsons, deputy director of programs for NASA’s Exploration Ground Systems, said one of these lightning bolts was one of the strongest NASA has seen since installing the lightning protection system. “It hit the catenary cable that runs between the 3 towers”, Parsons wrote in a tweet from the EGS Twitter account. “The system worked extremely well and kept SLS and Orion safe.”
The SLS is supposed to carry the Orion spacecraft on an unmanned mission around the Moon as part of the artemis programa flight called Artemis I. That mission, tentatively scheduled for this summer, is supposed to prepare the rocket, and NASA, for the mission that will eventually carry humans to the lunar surface.
