At end of two-week-long lunar day, convoy of tractors, each pulling two of its three trailers moves cautiously across rough terrain near plain of Sinus Roria (Dewy Bay). Glare of mountain range to north is caused by setting sun. Remainder of scene is illuminated by greenish earth light.
Seen from abandoned cargo ship with “full earth” shining i sky, passenger ships take off for return trip from moon to space station’s orbit.
Cutaway of plane in the foreground shows personnel, tractors in ship.
Advance party, after landing on Martian snow in ski-equipped plane, prepares for trip to equator. Men live in inflatable, pressurized spheres mounted on tractors, enter and leave through air locks in the central column. Sphere on tractor is just being blown up. Cutaway of tractor, foreground, shows closed-circuit engine, run by hydrogen peroxide, oil. Trailer cutaway shows fuel supply, cargo.
Near wheel-shaped space station 1,000 miles from the earth, built especially for assembly of the Mars expedition, weightless workers put together 10 rocket ships required for the flight. Three of the huge space craft have torpedo noses which convert to planes for landing on the planet.
The first landing party takes off for Mars. Two other landing planes will wait until runway is prepared for them, and then the remaining seven ships will stay in 600-mile orbit. Arms on cargo ships hold screenlike dish antennas (for communication), trough-shaped solar mirrors (for power).
After 15 month exploration, the Mars expedition prepares for return flight to earth. Two landing planes are set on tails, with wings and landing gear removed. They will rocket back to the 600-mile orbit on first leg of journey.
The unloading on the moon. Twenty-four hours after landing, supplies have been stowed in caterpillar tractors. Hold of cargo ship (r.) is being lowered to ground in sections, to be used as prefabricated headquarters, Earth is at center; halo effect is caused by sun, hidden behind sphere of rocket ship at left. Diagonal streak in sky, the zodiacal light, is caused by sun’s ray reflecting from cosmic dust. The red star at left is Mars.
Landing on the moon. Ten minutes before touchdown, rocket motors are switched on to slow down ships’ high-speed fall caused by the moon’s gravity. Vehicles are maneuvering 550 miles above landing area known as Sinus Roris (Dewy Bay), dark plain above cargo ship in lower left.
