CLM-1373 Two years after SP-413, a later NASA study's optimised Moon launcher was far shorter, about half a kilometre, because it accelerated at 1000 g instead of 30 g. It would throw about 42 kg a second at lunar escape speed.
CLM-1374 A 1979 NASA paper let small, hand-picked crews live in faster-spinning habitats (3 turns a minute), but held large settlements of ordinary people to 1 turn a minute or less, to avoid motion sickness.
