A dawn view of the Artemis I Area Launch System (SLS) and Orion spacecraft at Launch Pad 39B at NASA’s Kennedy Area Heart in Florida on March 21, 2022. The SLS and Orion atop the cellular launcher have been transported to the pad on crawler-transporter 2 for a prelaunch take a look at referred to as a moist gown rehearsal. Artemis I would be the first built-in take a look at of the SLS and Orion spacecraft. In later missions, NASA will land the primary lady and the primary particular person of shade on the floor of the Moon, paving the way in which for a long-term lunar presence and serving as a stepping stone on the way in which to Mars.

At roughly 5 p.m. EDT at this time (April 12, 2022), the launch group arrived at their stations contained in the Launch Management Heart at NASA’s Kennedy Area Heart in Florida. The countdown will start half-hour later at 5:30 p.m. or L-45 hours, 10 minutes earlier than the preliminary goal T-0 for the moist gown rehearsal take a look at for NASA’s Artemis I mission. Groups are continuing with a modified take a look at, primarily centered on tanking the core stage and minimal propellant operations on the interim cryogenic propulsion stage (ICPS) with the bottom programs at Kennedy. Tanking operations are scheduled to happen on Thursday, April 14.
Meteorologists with the U.S. Area Pressure 45th Area Wing predict favorable climate for propellant loading operations. Climate constraints stipulate there have to be lower than a 20% probability lightning inside 5 nautical miles of pad throughout the first hour of tanking. Winds additionally should not be above 37.5 knots and the temperature can't be beneath 41 levels Fahrenheit.
In a single day, groups will energy up Orion and the Area Launch System core stage, cost core stage battery, and put together the 4 RS-25 engines, which won't be lit throughout the take a look at.
Through the take a look at, the timing for some occasions on account of a number of deliberate operational demonstrations tied to particular capabilities and take a look at goals might differ from the day of launch countdown. These demonstrations embody assessments on the cryogenic programs and an roughly three-minute maintain contained in the terminal depend, which might not usually happen on launch day. If wanted, the take a look at group can also maintain as essential to confirm situations earlier than resuming the countdown, or use the take a look at window or lengthen past it, if consumables and assets permit them to finish take a look at goals.
Along with updates on this weblog, NASA will present dwell updates on the Exploration Floor Techniques Twitter account. NASA can be streaming dwell video of the rocket and spacecraft at Launch Pad 39B on the Kennedy Newsroom YouTube channel. Exercise on the launch pad will possible not be seen throughout nearly all of the countdown, however some venting could also be seen throughout tanking on April 14.
The following operational replace will likely be posted the morning of April 13.
