While Apollo 9 astronauts were preparing for outer space, two crews of U.S. aquanauts began new missions to determine how well man can exist in inner space-the underwater depths...
...that their mission would continue successfully for its scheduled two-month duration. If everything goes according to plan, the aquanauts hope to complete underwater biological and geological studies, learn more about diving and sonar techniques and supply medical and behavioral data that will help scientists plan the longer manned space flights of the future...
...Lunar Module (LM) but is becoming known as "the Spider." Scheduled to be tested in manned flight for the first time next week during the flight of Apollo 9, the Spider is the homely offspring of a concept of Aeronautical Engineer John Houbolt, an unsung hero of the U.S. space program. NASA officials now agree that without Houbolt's lonely campaign early in the 1960s, the U.S. would have been hard pressed to meet John Kennedy's goal of landing men on the moon before...
...favored an earth-orbital-rendezvous technique; two or more rockets would be used separately to launch a spacecraft and fuel-carrying stages into earth orbit, where they would be assembled for a flight to the moon. Pasadena's Jet Propulsion Laboratory, which is most concerned with unmanned space shots, proposed that extra fuel and supplies be rocketed to the surface of the moon and then be brought together into a supply depot by a remotecontrolled tractor. The astronauts would land near...
While the various factions wrangled, Engineer Houbolt, whose work at NASA's Langley Research Center was not directly connected with space flight, was impressed by still another moon-landing technique: the lunar-orbit rendezvous. Houbolt's plan was to leave the mother craft in orbit around the moon while a light, ferrylike craft descended from it to the lunar surface carrying only one or two of the astronauts. Later, the little craft could blast off, rendezvous and dock with the mother ship, and then be left behind in lunar orbit as the astronauts returned to earth...
