Electron’s “main” thread uses Node. You can then communicate between it and browser windows over IPC easily with their APIs.
So if they’re running their UI on Electron, it could be on Node.
Node is not for UIs, so they're definitely not using Node for that. It was confirmed that the UIs in the Dragon capsule (which, sorry for being pedantic, is not really the "rocket") ran on top of Chromium. It's possible SpaceX uses Node under the hood somewhere, but I don't believe that has been confirmed anywhere.
Also kind of interesting to note that it's only the Dragon capsule with humans that has controls, the capsule (and rocket) are both autonomous. The controls on the capsule are only there "just in case".
