Not viable. Liquid hydrogen always requires foam insulation. Also, no point in a winged engine return pod.I like the Idea of that as part of a Buran type Shuttle II....as in figure 21. here:
---but there could be another possibility:
Imagine if you will, an all hydrogen External Tank made from the start to be used as a wet workshop---with no foam problems.
The payload of crew/cargo goes in a forward cargo carrier in the nose of the External Tank....top mount...escape tower, etc.
The oxidizer tank is inside the unmanned orbiter where the payload bay used to be.
This way, you can still fly back the SSMEs.....the orbiter is simplified, and the ET can has smaller motors to take care of itself.

Double hull is not viable.I am not saying to not have foam. Wet workshops also need insulation. There would be an outer smooth layer-a double hull is also good for a simple all hydogen ET station module. There are hydrophobic coatings that could be added to the second skin to reduce ice...so it slides off at lift-off. Remember- the oxidizer is in the orbiter...so no oxygen ramp. The payload is atop the ET here. My point is is that the tankage for low density LH2 is an asset, for wet workshops need no grid fins, TPS, or legs-and need not endure the Adama maneuver. Winged spaceflight has its place. My thought was that Wayne Ordway' Shuttle II would prevail with a Buran type orbiter that could be replaced by factory pods the orbiter could service...returning tons of goods to Earth..sparking investments...with shuttle 3 spaceplanes grown in space. To me...orbital factories need come first and RLVs last.
Don't need wings to produce lift.Not viable. Liquid hydrogen always requires foam insulation. Also, no point in a winged engine return pod.
Actually there was a 'point' to adding significant lift to the engine recovery pods: Landing location
The deep Outback of Australia or the Mexican Northern deserts were NOT convenient to land and recover from. Ballistic recovery pods didn't/couldn't have the cross-range needed.
Wrong.But without factories as a destination, RLV markets can be over saturated. Space has to be funded by more than a handful of squabbling billionaires...and having goods spill out of some crafts' hold is probably what is needed to mainstream space beyond vanity projects that turn many off. We know what you are against. Tell me what you are for.
