...M.P.H. Harper's group figures that the 240,000-mile trip to the moon would take only 48 hours; in the celestial vacuum their ship would attain a speed of 20,000 m.p.h.

Passengers would be protected against acceleration effects by springy hammocks, against extreme heat & cold by rotation of the ship's outer shell...
