NASA Orion spacecraft made its penultimate terrestrial roadtrip late Thursday night when it cruised into the Automobile Meeting Constructing on the Kennedy House Middle. The following time it hits the street will probably be atop the totally assembled House Launch System rocket for last prelaunch preparations for Artemis 2 on the launch pad.
The spacecraft, named “Integrity” by its four-member crew,” slowly made the roughly seven-mile journey from the Launch Abort System Facility to the VAB, arriving on the entrance to Excessive Bay 4 round midnight (0400 UTC). The trek got here nearly 4 years to the day after NASA rolled the Orion spacecraft used on the Artemis 1 mission to the VAB.
Not like that rollout although, this transport got here with far much less pomp and circumstance, provided that the U.S. federal authorities is on day 16 of a shutdown with many components of the NASA workforce furloughed.
Nevertheless, the rollout operation was capable of transfer ahead as a result of vital capabilities associated to the Artemis 2, 3 and 4 missions have been included in exemptions agreed by the White Home for the shutdown that started on Oct. 1.
Throughout a Sept. 22 mission overview briefing on the Johnson House Middle, Charlie Blackwell-Thompson, the Artemis 2 launch director, famous that the Orion Stage Adaptor was set to be stacked as a part of the rocket in Excessive Bay 3 the week forward of the spacecraft’s arrival.
As soon as Orion is stacked atop the remainder of the SLS rocket, that’s when Blackwell-Thompson mentioned the check marketing campaign will actually kick into gear. A majority of that work will occur contained in the VAB.
She mentioned whereas a few of work will mimic operations seen in the course of the Artemis 1 marketing campaign, just like the Finish-to-Finish Comm Check and the Interface Verification Check, there are additionally some new additions that issue within the astronaut component.
“These new assessments include the Countdown Demonstration Check, which is about our crewed flight. Again within the shuttle days, we had the same check that was referred to as TCDT: Terminal Countdown Demonstration Check,” Blackwell-Thompson mentioned.
“That’s the place we swimsuit up the crew, they arrive out, we undergo our guidelines and our countdown. They’ll enter the ship, we’ll get them strapped in, we’ll do comm checks, we’ll do the configuration of the crew module and we’ll depend all the way down to within terminal depend earlier than we’ve a deliberate cease.”

Throughout that cease, Blackwell-Thompson mentioned they can even do an egress demonstration, which can wrap up half one in all that testing marketing campaign. As soon as the Countdown Demonstration Check (CDDT) Half 1 is full, groups will conduct a check of the flight termination system and start last car closeouts.
“And when all of that’s completed, we’ll get able to roll out from the VAB to the pad,” Blackwell-Thompson mentioned, referring to the roughly four-mile journey. “As soon as we get to the launch pad, we’ll make the connections between the Cell Launcher and the pad. We now have somewhat little bit of testing that we’ll do on the market as nicely.”
These pad-connected assessments at Launch Advanced 39B contain configuring the emergency egress system, a sequence of slide wire baskets that will be capable to enable the closeout crew and the astronauts to shortly get away from the rocket in an emergency, previous to the arming of the Launch Escape System. Blackwell-Thompson mentioned that is the second a part of the CDDT.
After that it’s time for the moist gown rehearsal.
“That’ll be a full tanking of the car, core stage and higher stage. We’ll get right into a terminal depend, and once more, we’ll depend down inside a terminal depend to concerning the 29-second level after which we’ll terminate that check,” she mentioned. “We’ll go evaluate the info and some days later, we’ll get into launch countdown.”
Blackwell-Thompson mentioned the work on the pad is a roughly 18-day course of with just a few contingency days in-built. The moist gown rehearsal occurs close to the top of that circulation.
Like Artemis 1, launch countdown itself is a two-day course of. Blackwell-Thompson mentioned after the moist gown rehearsal, the car gained’t be rolled again to the VAB, barring some main difficulty that may’t be resolved on the pad.
This primary crewed flight of the Artemis program is about to launch no sooner than Feb. 5 from the Kennedy House Middle. Following earlier delays because of ongoing evaluation of the warmth protect’s efficiency seen on the Artemis 1 mission, NASA set a aim of launching no later than April 2026 with aspirations to fly before that.
Groups are nonetheless working to nail down the precise launch home windows accessible to them in every month, however typically, they vary from 4 to eight days.
Relying on precisely after they launch, the four-person crew consisting of three NASA astronauts and a Canadian House Company astronaut will spend roughly ten days within the confines of the Orion capsule, blazing a path for future crews to coach for missions that can take them again to the Moon’s floor.
