NASA Go for Artemis I Wet Dress Rehearsal of SLS Rocket, Orion Spacecraft, and Exploration Ground Systems

The Moon serves as a background for the Artemis I Space Launch System (SLS) and Orion spacecraft at Launch Pad 39B at NASAs Kennedy Space Center in Florida on March 21, 2022. The SLS and Orion atop the mobile launcher were transferred to the pad on crawler-transporter 2 for a prelaunch test called a wet gown rehearsal. Artemis I will be the first incorporated test of the SLS and Orion spacecraft. In later objectives, NASA will land the very first woman and the very first person of color on the surface of the Moon, paving the method for a long-term lunar existence and functioning as a stepping stone on the way to Mars.

In a pre-test review on March 28, NASA gave the “go” to continue with the Artemis I damp dress wedding rehearsal scheduled for April 1-3. The roughly two-day test will run the Artemis I release group through operations to pack propellant into the rockets tanks, carry out a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain the tanks to offer them a chance to practice the timelines and treatments they will use for launch.
They will recycle back to 10 minutes prior to launch and carry out a second terminal countdown to approximately 9.3 seconds before launch, then end the countdown. In some cases called a “scrub,” launch controllers might decide not to continue with launch if a technical or weather condition problem occurs throughout or prior to the countdown.
NASA will provide a live video stream of the rocket and spacecraft at the launch pad beginning at Noon EDT on April 1 on the Kennedy Newsroom YouTube channel. In addition to updates on this blog site, NASA also will supply operational updates on the Exploration Ground Systems Twitter account.

The Moon serves as a background for the Artemis I Space Launch System (SLS) and Orion spacecraft at Launch Pad 39B at NASAs Kennedy Space Center in Florida on March 21, 2022. They will recycle back to ten minutes prior to launch and conduct a 2nd terminal countdown to approximately 9.3 seconds before launch, then end the countdown. Sometimes called a “scrub,” launch controllers might decide not to continue with launch if a technical or weather condition concern emerges throughout or prior to the countdown.
