Alan Shepard explosion caused the moon landing to be aborted and nearly resulted in the loss of the crew. It became a joke between Shepard and Lovell, who would offer to give Shepard back the mission each time they bumped into each other. The failure of Apollo 13 delayed Apollo 14 until 1971 so that modifications could be made to the spacecraft. The target of the Apollo 14 mission was switched to the Fra Mauro formation, the intended destination of Apollo 13. Shepard made his second space flight as Commander of Apollo 14 from January 31 to February 9, 1971. It was
Apollo spacecraft feasibility study a special symposium of the American Astronautical Society in Denver, Colorado. The Martin Company spent about $3 million, employing almost 300 persons for the better part of the six-month term, to produce the most elaborate study of the three, not only following all the Space Task Group guidelines, but also going far beyond in systems analysis. The complete proposal consisted of 9,000 pages. Focusing on versatility, flexibility, safety margins, and growth, this was the only study that detailed the progression of steps from lunar orbiting to lunar landing. Martin's spacecraft would have been similar to the Apollo spacecraft that ultimately
