The author discusses the equipment needed and some of the problems to be overcome for a manned trip to the moon. Since a moon spaceship would have to accelerate, maneuver, and decelerate several times during the round trip, the weight of the fuel it would have to carry initially would make the ship too heavy -- over 15,000 tons -- to launch from earth. The solution is to assemble the spaceship from components launched separately into an earth orbit and joined in space. The round trip should take about ten days, and three astronauts would be needed to man the ship. A spaceship of this type, with a 3-man crew, would need 40.8 kilograms of food, 95 kilograms of water, 47.5 kilograms of oxygen, and about 470 kilograms of air conditioning and power generating equipment. In addition, there would be 227 kilograms of other equipment, 454 kilograms of instruments and gauges, radiation and meteor protection devices, etc. According to this project, total weight of the spaceship, not including motors and fuel reserves, would be 13.4 tons. Other projects, which call for a landing on the moon, estimate the total weight at between 50 and 70 tons.
