Apollo_7 Apollo 7 (October 11-22, 1968) was the first manned mission in the Apollo program to be launched. It was an eleven-day Earth-orbital mission, the first manned launch of the Saturn IB launch vehicle, and the first three-person American space mission. The flight was an open-ended flight which meant that the mission would continue as long as it was safe and there were enough consumables on board, including oxygen.
