Now lets see how the old LEM stacks up. It's too physically large to
fit inside the payload fairing of anything other than SLS or Falcon
Super Heavy. It relies on a docking adapter that doesn't exist
anymore. It's battery powered and only has power for a 75 hour
duration.

What is proposed for longer stays ... an APU, solar arrays?

It's made largely out of, well, tissue paper. Atmosphere
is pure oxygen at 5 PSI or so. It uses old hypergolic engines fueled
by Aerozine 50 and using dinitrogen tetroxide as the oxidizer.

The main advantage being non-cryogenic. What fuel and oxidizer would
be superior for a LEM today?
