00:00 On this day in space.
00:03 On November 14th, 1969, the Apollo 12 mission launched to the moon.
00:08 This was the second moon landing of the Apollo program.
00:11 The two astronauts on board were Pete Conrad and Alan Bean.
00:15 Richard Gordon stayed in the command module and orbited the moon while his crewmates went to the surface.
00:20 The astronauts made a pinpoint landing in a lunar mare called the Ocean of Storms.
00:25 The previous moon mission, Apollo 11, drifted far from the planned landing site.
00:29 But Apollo 12 landed close to a scientific target.
00:32 That target was a robotic lander called Surveyor 3.
00:36 Scientists wanted to look at Surveyor 3 to see how well the spacecraft lasted on the moon since it landed there more than two years earlier.
00:42 Apollo 12 also did a lot of moon science.
00:45 The astronauts picked up 75 pounds of moon rocks.
00:48 Most of the rocks were basalts that formed from molten lava.
00:52 These basalts showed the Apollo 12 landing site is more than 3 billion years old.
00:57 And that's what happened on this day in space.
