Apollo 12 was the sixth crewed mission in NASA's Apollo program and the second to land astronauts on the Moon. Launched on November 14, 1969, the crew included Commander Charles "Pete" Conrad, Lunar Module Pilot Alan L. Bean, and Command Module Pilot Richard F. Gordon. Despite being struck by lightning twice during its launch, the mission successfully continued. On November 19, Conrad and Bean descended to the lunar surface in the Lunar Module "Intrepid," landing near the Surveyor 3 spacecraft, a robotic probe that had landed on the Moon in April 1967. The pair conducted two moonwalks, collecting samples and performing experiments. Meanwhile, Gordon orbited above in the Command Module "Yankee Clipper." After a successful lunar surface mission, Conrad and Bean rendezvoused with Gordon and began their journey back to Earth, splashing down safely on November 24. Apollo 12 further demonstrated the feasibility and sustainability of crewed lunar exploration.

3. MISSION OBJECTIVE Apollo 12 aimed to demonstrate the ability to land at a
specific location on the lunar surface. In this case, the
targeted site was near the Surveyor III spacecraft, which
had landed on the Moon in April 1967

Lightening Strike
Shortly after liftoff, the Saturn V rocket carrying Apollo
12 was struck twice by lightning. This caused a
number of warning lights to turn on and resulted in the
fuel cells going offline. The quick thinking of the flight
controllers, especially John Aaron's recommendation
of the "SCE to AUX" switch command, helped restore
normal functioning, and the mission continued as
planned.
12. MISSION BACKGROUND
Precision Landing
Apollo 12 demonstrated a
precision landing, aiming for a
spot close to the Surveyor III
spacecraft, which had landed
on the Moon in April 1967.
Conrad and Bean succeeded
in landing within walking
distance (about 200 meters) of
Surveyor III. This was an
impressive demonstration of
NASA's ability to target
landing sites.
13. MISSION BACKGROUND
Lunar Activities
Conrad and Bean conducted two
extravehicular activities (EVAs) on the
lunar surface. They collected samples,
set up the Apollo Lunar Surface
Experiments Package (ALSEP), and
visited the Surveyor III spacecraft.
Pieces of Surveyor III were brought
back to Earth to study the effects of
long-term exposure to the lunar
environment

east of Pago Pago, American Samoa, on Nov. 24, 1969,
successfully completing the second lunar landing mission.
