I was reading about the recent selection of Blue Origin for a second Lunar Lander, and a comment on an article caught my eye. Where exactly are any of the engines on the new lander?
Here you can see the original National Team proposal, a very tall design with the crew compartment way up top and the lander's main engines (and RCS) at the bottom, as well as a set of engines in the middle of the stack (not pictured) for when the upper section lifts off from the Moon, akin to how the Apollo lander worked. A video on their lander can be found here where you can actually see the two main landing engines tucked away, not visible in the screenshot below (taken from that very video).
Old Lander:
However, when we look at the render from the recently accepted proposal, the crew compartment is at the bottom and I at least can't see where the engines/RCS are. If it's similar to how the prior proposal had, with the main engines tucked up centrally and therefore not visible, that would mean that they'd have to be awfully close to the crew, and also have some way of routing LH2 and LOX either through or around the crew compartment, both of which seem sketchy to me. I also don't see any RCS thrusters, though they could be on those rectangular-ish sections covered by the gold colored foil/coating.
New Lander:
In summary, I'm curious whether the engines are really that close to the crew, as well as where/how the propellant is routed if so, since it's not clear from this render, nor have I been able to find much if any information on it. It's also possible that the render pictured below does not include all of the details.
