The command module was a spacecraft used by NASA during the Apollo program in the 1960s and 1970s. It was the primary component of the Apollo spacecraft, and was responsible for the navigation, guidance, and control of the spacecraft during its journey to the Moon.
The command module was also the living quarters for the astronauts during the mission, and contained life support systems, communication equipment, and scientific instruments. It was cone-shaped, with a diameter of about 13 feet and a height of about 11 feet.
The command module was designed to be reusable, and was equipped with a heat shield to protect it during reentry into the Earth’s atmosphere. It was also equipped with a parachute system to help it land safely on the surface of the Earth.
