Apollo 12 entered a lunar orbit of 170.2 by 61.66 nautical miles (315.2 by 114.2 km; 195.9 by 70.96 mi) with an SPS burn of 352.25 seconds at mission time 83:25:26.36. On the first lunar orbit, there was a television transmission that resulted in good-quality video of the lunar surface.
The Apollo 12 empty S-IVB, Instrument Unit, and spacecraft adapter base, had a mass of about 14 tonnes; 15 short tons (30,000 lb). [6] This is less than one-fifth of the 77.1-tonne; 85.0-short-ton (169,900 lb) mass of the Skylab space station, which was constructed from a similar S-IVB and fell out of orbit on 11 July 1979. [7]
In addition, the three-person crews of Apollo 8 and Apollo 10 also entered lunar orbit, and the crew of Apollo 13 looped around the Moon on a free-return trajectory. All nine crewed missions to the Moon took place as part of the Apollo program over a period of just under four years, from 21 December 1968 to 19 December 1972.
[11] [12] Two "A-type" missions performed uncrewed tests of the CSM and the Saturn V, and one B-type mission performed an uncrewed test of the LM. The C-type mission, the first crewed flight of the CSM in Earth orbit, was performed by Apollo 7.
Apollo 8 was the first crewed mission to orbit the Moon, but did not land. On December 21, 1968, ... Surveyor 3 camera brought back from the Moon by Apollo 12, ...

Due to the lunar landing site restrictions that resulted from constraining the launch to a free return that flew by the Moon, subsequent Apollo missions, starting with Apollo 12 and including the ill-fated Apollo 13, used a hybrid trajectory that launched to a highly elliptical Earth orbit that fell short of the Moon with effectively a free ...
The design was based on the lunar orbit rendezvous approach: two docked spacecraft were sent to the Moon and went into lunar orbit. While the LM separated and landed, the CSM remained in orbit. After the lunar excursion, the two craft rendezvoused and docked in lunar orbit, and the CSM returned the crew to Earth. The command module was the only ...
