It was 46 years ago
today, November 14, that NASA (National Aeronautics and Space
Administration) launched, Apollo
12, their second manned moon mission. It was an overcast day full
of rain and wind when the three astronauts; Richard F. Gordon Jr.,
Charles “Pete” Conrad, and Alan L. Bean; climbed aboard the
Apollo capsule. Everything went fine with the preflight check as the
count-down commenced. At 8:22 am PST (16:22 UTC) the Saturn V rocket
blasted off from the launchpad into the sky over Cape Canaveral,
Florida. Just seconds after the rocket cleared the tower something
unexpected happened.
“What
the hell was that?” asked Gordon. Twenty seconds of confusion
ensued, and then another disturbance occurred.
The
answer to Mr. Gordon's question was lightning
struck the Apollo 12 command module. The massive discharge caused
the fuel cells to detect an overload and they went off-line. With the
fuel cells off-line the command module had to rely on batteries. That
meant that they now were trying to power a 75 ampere load on 28 amps
provided by the batteries. This was causing several malfunctions and
all the warning lights where flashing. That was not the worst though.
About 30
seconds after the first strike they suffered another lightning bolt.
This one the “8-ball” altitude indicator. The astronauts and
mission control were thinking they would have to abort the mission
less a minute into the flight. Just then John Aaron; electrical,
environmental, and consumable engineer; remembered his training on
how to handle the situation. He relied the solution to the crew of
Apollo 12 that plug in the proper sequence to get everything back on
track to continue the mission to the moon.
Charles
“Pete” Conrad Jr. had a rough road to travel on his way to
NASA. As a youth he struggled in school with a dyslexia problem. He
was expelled after failing his junior year of high-school. His mother
was able to get him into a new school that helped him work around his
dyslexia. After that he excelled in his academic studies enough that
he was accepted to Princeton University with an ROTC Navy
scholarship. He went on to become a Navy aviator, flight instructor,
test pilot, and one of the “Mercury Seven” astronauts.
