At NASA Headquarters, George Mueller and other planners created a far-reaching plan that Administrator Paine made even more ambitious in adapting it for Nixon’s Space Task Group. The task group’s timetable called for a twelve-man space station and a reusable space shuttle as early as 1975. By 1980, the station would have grown into a fifty-man space base; five years later there would be a hundred men in orbit. Meanwhile, there would be a base in lunar orbit by 1976, with a base on the lunar surface two years later. Then, as early as 1981, the first manned expedition to Mars would depart from earth orbit.
