Nah. First of all, VR headsets are great for working in a specific room, when one is standing in the middle of it. Not when you are looking down nooks and crannies. SteamVR would lose lighthouse tracking 100% of the time, disorient and grey out. It could actually be dangerous. Second, the passthrough cameras are ass quality. It won’t be enough to see cables well. They’re made with the idea of “I want to see where a dog-like object is, so I don’t step on my dog”. Three, headsets are heavy and tiring, especially if holding a phone is too much. Now you are holding two screens close to your face. You most likely cannot fit glasses well under them either. So you need to add prescription lenses, which make it usable by one person only.
What you need is a small wireless camera on a cap they put on their head, that’s connected to the PC to stream the video to you. It already adds complexity - where the camera needs to be charged, needs to be turned on etc, but not as much as a VR headset.
Then you add into it some sort of interactive board features. Slack for instance lets you draw on someone’s screen when sharing. Either two people would need to be there, one to look and one to see what you are marking, or you could just stream to their phone, where they see the output of the camera and you can mark / write on it to mark what you need to.
But yah, VR isn’t the tech for this.
Your blood would literally boil the second you are exposed to the vacuum of space. You are dead long before you reach it. Maybe if they fire you off in a torpedo. But then some mutineer could fuck with the targetting systems and keep you alive.
