As with the Army and Navy in World War II, NASA had grown rapidly during the 1960s. Similarly, just as those military services saw a sharp falloff in funding in the wake of victory, the success of the piloted Moon landings brought insistent demands that NASA should shrink considerably. In facing those demands, and in overcoming them to a degree, NASA established itself as a permanent player in Washington.During 1969, with Nixon newly elected and the first astronauts setting foot on the Moon, NASA Administrator Thomas Paine led a push for a future in space that promised to be expansive. He aimed at nothing less than a piloted expedition to Mars, propelled by nuclear rocket engines that were already in development. En route to Mars, he expected to build space stations and large space bases. Almost as an afterthought, he expected to build a space shuttle as well, to provide low-cost flight to these orbiting facilities.Soon after Neil Armstrong made his one small step in the lunar Sea of Tranquility, Paine received a cold bath in the Sea of Reality. Nixon's budget director, Robert Mayo, chopped a billion dollars from Paine's request. This brought an end to NASA's hopes for a space base and for flight to Mars. It appeared possible, however, to proceed with the space station and the shuttle, as a joint project. The shuttle drew particular interest...
