Early Apollo configuration for Direct Ascent and Earth Orbit Rendezvous , Once Kennedy had defined a goal, the Apollo mission planners were faced with the challenge of designing a spacecraft that could meet it while minimizing risk to human life, cost, and demands on technology and astronaut skill. Four possible mission modes were considered: Direct Ascent : The spacecraft would be launched as a unit and travel directly to the lunar surface, without first going into lunar orbit. A 50,pound 23, kg Earth return ship would land all three astronauts atop a ,pound 51, kg descent propulsion stage, [35] which would be left on the Moon. This design would have required development of the extremely powerful Saturn C-8 or Nova launch vehicle to carry a ,pound 74, kg payload to the Moon. These would be assembled into a single spacecraft in Earth orbit. Lunar Surface Rendezvous: Two spacecraft would be launched in succession.
