Apollo 13 - Prime Crew Portrait

S69-62224 (December 1969) --- The members of the prime crew of the Apollo 13 lunar landing mission (left to right) are astronauts James A. Lovell Jr., commander; Thomas K. Mattingly II, command module pilot; and Fred W. Haise Jr., lunar module pilot. They are seated in front of a scene of the Lagoon Nebula, with the mission insignia and two items of early navigation in the foreground. Represented in the Apollo 13 emblem (center) is Apollo, the sun god of Greek mythology, symbolizing that the Apollo flights have extended the light of knowledge to all mankind. The Latin phrase Ex Luna, Scientia means "From the Moon, Knowledge." The Hindu astrolabe in Sanskrit (on right) was used to predict the position of celestial bodies before the invention of the octant (on left) was used in 1790 to determine the altitude of celestial bodies from aboard ship.
