On October 11, 1968, NASA launched the first Apollo crew into space. This mission, Apollo 7, opened the spaceways for the moon landing the following July. Apollo 7 had the following objectives: Demonstrate Command and Service Module (CSM) with crew performance; demonstrate mission support facilities' performance during a crewed mission and demonstrate Apollo rendezvous capability; demonstrate live TV broadcasts from space.
From NASA:
The Apollo 7 crew was commanded by Walter Schirra, with Command Module Pilot Donn Eisele, and Lunar Module Pilot Walter Cunningham. The mission consisted of an 11-day Earth-orbital test flight to test the Apollo command and service module. It was also the first time a crew flew on the Saturn IB rocket.
Although Apollo 7 was a complete technical success, it was born out of a tragedy. After the fatal fire that took the lives of the Apollo 1 crew—Gus Grissom, Roger Chaffee, and Ed White—the Apollo 7 crew took over the mission.
Apollo 1 was supposed to be the first crewed Apollo mission. During a launch rehearsal test at Cape Kennedy, an electrical fire broke out in the cabin. Because the cabin atmosphere was pure oxygen, the fire spread incredibly quickly. The fire also created intense pressure inside the cabin, and because the hatch could only swing inward, the crew was stuck inside.
All further crewed missions had to wait until NASA could determine the sources of the mishap—technical and organizational—and ensure that nothing like it would happen again. In the 21 months between Apollo 1 and Apollo 7, the Apollo spacecraft and spacesuits were redesigned to more safely fly crews to space.
