...approached the moon early this week, Apollo 12 was scheduled to insert itself into a nearly circular orbit about 69 miles above the lunar surface. Conrad and Bean would then crawl through the tunnel leading from Yankee Clipper into Intrepid and cast off in the landing craft, leaving Gordon to guide the command ship through 19 solo orbits of the moon. Early Wednesday the two men would begin the gentle, arcing descent to the lunar surface...
Additional Risks. If all continued to go well, the mission would take ten days -two days more than the voyage of Apollo 11. Conrad would attempt a pinpoint landing only a few hundred feet from the resting place of Surveyor 3, the unmanned moon probe that soft-landed on the lunar surface April 19. 1967. He and Bean would stroll for as long as 74 hours on the moon and collect up to 75 lbs. of lunar rock. Most important, Apollo 12 would leave behind a more sophisticated array of sensitive instruments than those left by Apollo 11. Powered...
...free return" trajectory toward the moon. In the event of engine failure, such a path would allow the spacecraft to be whipped around the moon by lunar gravity and hurled back safely to the earth. Some 31 hours after liftoff, however, Apollo 12's situation was changed drastically. Conrad fired the 20,500-lb.-thrust service propulsion engine and sent his ship into a "hybrid" trajectory. The new flight path was necessary to set the astronauts down at their landing site on the Ocean of Storms at the right time of lunar day. On this course, too, Apollo could...
...Apollo 12's target, Intrepid must set down just east of the Surveyor Crater's edge. Conrad will probably not be able to see the Surveyor as he swoops down, for the craft will be in the deep shadow of early lunar morning. But he should have little difficulty spotting the Surveyor Crater. It forms the torso of what astronauts call the "Snowman," a distinctive cluster of five adjacent craters...
Exquisite Precision. More than pride is involved in the accomplishment of a pinpoint landing. If Intrepid touches down too far from its target crater, Conrad and Bean may not have enough oxygen in their back-up life-support packs for the planned walk to the Surveyor spacecraft. An inaccurate landing would also affect plans for next spring's scheduled Apollo 13 visit to a highlands area near Crater Fra Mauro. Before as tronauts risk landing in such a rugged area, NASA officials must be convinced that a lunar module can be set down on a selected segment...
