U.S. Spacewalk 94 Animation – March 17, 2026

An animation of U.S. spacewalk 94 scheduled for Wednesday, March 16 when NASA astronauts Jessica Meir and Chris Williams will prepare the 2A power channel for future installation of International Space Station Roll-Out Solar Arrays (IROSA) which will provide additional power ahead of safe and controlled space station deorbit. The duo will also swab the outside of the orbiting lab for microorganisms. This animation was narrated by flight director Diana Trujillo.

What is said in the film

Once the hatch open, we're going to have, Jessica coming out first. She gets the strut back, which is an eight foot long bag, and then she gets a cable bag. Then Chris comes out. After they're both outside, Jessica will be the first one that will start translation to the P4 area where the MOD KIT is located. So you'll see it here in the animation.

She starts moving through the Truss all the wa down to the MOD KIT. At the same time, Chris is going to do a quick stop, get a WIFEX which is an equipment that will give him more distance once he gets into the foot restraint so he can reach to the MOD KIT itself. Once they get there, they're going to cinch down the bags and then they begin the installation. So they start with mid-strut and then Jessica gets the other side- the left mid-strut and the lower strut-hands it to Chris who's already on the foot restraint, then Jessica goes around and Chris will then be turned, so that he can be facing on the other side of the canister where he will start now working with Jessica to put the mid-struts themselves. Okay, so here’s where they bolt the second mid-strut.

And after that, the whole assembly of the MOD KIT is now completed with the cables that will be required for later on. After that's completed, Jessica is going to go down, on one side of the area where they were, put the DDCU jumpers, while Chris is moving now to the Race Ring, as I mentioned before, to take a snapshot of the current state. So here he goes. He takes a few pictures for us to understand the state. And then he comes back.

Once he comes back to the same location where we had cinched down the two bags, he will begin now the torque reset. So open the cable bag, get the tool that he needs, and then he begins the torque resets for several of the boxes that you see here. Once that is completed, Chris is coming back to the airlock where he starts doing the microorganisms. So you can see that he has the canisters on his side. He brings in the tool, he does the swabbing, and then he puts it back into the tool.

At the moment he puts it on the tool, it locks in the sample, and so he goes for the next sample. There's seven samples that we're going to go do. The minimum number for our activity this go around is five samples. So in this specific view, you will see him going back inside the airlock to do two of the swabs that he has on his SEU. In the meantime, Jessica now has make it to a location on the truss where the robotic arm gets closer to her.

She puts the cover on the camera itself on the robotic arm and then the robotic arm moves out of the way, and she makes it back to the airlock. And here you see Jessica putting the cable bag back inside, and then back inside the airlock for the end of our EVA. And that will conclude EVA 94.
