What can you tell us about EVA T2 and zero-G push-pull? Will there be decoupled EVA?
TL;DREVA T2 and zero-G push-pull are in active development, with fuel-limited thrust, surface clambering and skimming, and a half-coupled, half-decoupled EVA, first for Squadron 42 and later the PU.
So the first thing to mention is probably good news. It's very much in development. We've got quite a few people working on it right now. A big change coming for EVA is that it's going to be requiring fuel. So the idea is you haven't got indefinite thrust. And that heavily ties into the zero-G push-pull. We want to encourage you to use it. So you're actually thinking about where you're expending fuel, where it's best to clamber on the surface instead of zooming around like Iron Man. So going back to the decoupled part, it's very much a part of both zero G and EVA. If you imagine you're clambering slowly over a surface, that's going to be the general sort of traversal whilst you're in zero G, but you will be able to push off. And that's going to be whether you're moving between different objects or if you're on the surface of a ship, going from one ship to another, or, say, the ship's exploded, you want to go get the cargo boxes, or perhaps you want to get to an asteroid so you can start mining, et cetera. That will be decoupled in terms of: I move in a direction, I keep moving until something else occurs to prevent me from moving. But we're also going to be introducing skimming across surfaces. So the slow, ponderous clambering movement is going to be one part of the zero-G push-pull, but you're also going to be able to push yourself along the surface. And that's the equivalent of a sprint in zero G, but it's going to be using Newtonian decoupled physics to achieve that. The EVA itself, it's changing a little bit. So I'd say it's sort of decoupled light. And before you get sad, let me describe why I say that. So the idea is you will thrust in a direction. You can then release the input and stop that thrust. You will continue indefinitely in that direction. If you start to look around, again, you keep going in that direction. But if I turn and then I give another thrust input, I will start to thrust in that direction. And the way that differs from the decoupled mode: you could be traveling in one direction, you turn 90 degrees and then you start to thrust in that direction, you've still got that momentum in the original direction. We want EVA to have more of a sense of the Iron Man flying sensation. So you will have the equivalent of coupled flight whilst you're reorientating yourself and changing the thrust vector. But once you've released the thrust input, then you go back to the decoupled model. So it's kind of a halfway in between. We've got that working now and it feels fun. We found the fun there. Hopefully that answers the question.
Yeah, and as you said, that's currently in development for Squadron 42, and then when it gets all proven out there, it'll make its way to the PU.
Exactly.
