...landing in Russia or the Indian Ocean during daylight hours, when it is easier to locate and reach the downed craft. The mission almost certainly will follow closely the trail of Zond-5 and Zond-6, the first craft to circle the moon and return safely to earth...
Tass, the Russian news agency, has confirmed that both Zonds were preparatory shots for a manned flight and carried living creatures to test radiation effects near the moon. U.S. scientists suspect that Cosmonaut Georgy Beregovoy successfully tested life-support systems for a manned lunar mission during the earth-orbit flight of Soyuz-3. If so, a Soviet lunar spacecraft may finally be man-rated-ready to carry passengers to the moon in December...
...altitude of 119 miles. After the S-2 is jettisoned in turn, the third-stage S-4B will ignite, using its 225,000-lb.-thrust engine to increase the spaceship's speed to 17,400 m.p.h. and insert it into a "parking" orbit around the earth...
Once the ship is in orbit, the astronauts and ground controllers will check out all the systems on board, making certain that they are operating properly and that the duplicate and backup systems are in working order. On their second revolution around the earth, if no problems have arisen, the Apollo crew will reignite the S-4B rocket engine over the Pacific near Hawaii. In a 5-min. 11-sec. burning period, the S-4B will accelerate to an "escape" velocity of 24,200 m.p.h., pushing Apollo out of earth orbit and off toward the moon...
...earth recedes behind them, the astronauts will separate their spacecraft from the S-4B, move about 50 ft. ahead of it, and then turn to face it. During this maneuver, protective panels will be jettisoned from the S-4B, exposing the dummy lunar module (LM) carried in its nose. The astronauts will then simulate docking with the LM-an operation that will be particularly important on the lunar-landing mission next year, when an Apollo spacecraft will dock nose-to-nose with a real LM before taking it into orbit around the moon. Finally, after the astronauts have jockeyed their...
