Apollo 12: Lightning Strikes, SCE to AUX, and a Nuclear Cask Hammer Fix

Sandwiched between the first landing and the Apollo 13 rescue, Apollo 12 is the unsung middle child of the lunar program. Its mandate was no longer survival but pinpoint precision: land within walking distance of the Surveyor 3 probe in the Ocean of Storms. This episode follows the all-Navy crew of Pete Conrad, Alan Bean, and Richard Gordon, formed after the death of Clifton Williams and honored with a fourth star on the mission patch.

On November 14, 1969, with President Nixon watching, the Saturn V triggered two lightning strikes that knocked the fuel cells offline and garbled telemetry, until controller John Aaron’s call to switch SCE to AUX saved the flight. We cover the hybrid non-free-return trajectory chosen for landing lighting, the Snowman crater landing 535 feet from Surveyor 3, Conrad’s $500 bet with Oriana Fallaci over his first words, the burned-out color TV camera, the plutonium fuel element freed with a geology hammer, the discovery of Copernicus ejecta, the deliberate crash of the ascent stage that rang the moon like a bell, and the rocket stage that returned in 2002 as a suspected asteroid.

  • Why NASA needed pinpoint landing accuracy to unlock future geological missions
  • How the signal conditioning equipment failed and why mission control debated the parachute risk in silence
  • Low sun angles, Ewan Whitaker’s crater hunt, and the Snowman formation that guided the descent
  • The lost camera timer, the surveyor parts cut off with bolt cutters, and Gordon’s multispectral orbital photography
  • The S-IVB stage rediscovered in 2002 as object J002E3, coated in white titanium dioxide paint
