Cotton-candy sky with launch day nigh. The Apollo 13 vehicle shines in the light of the setting sun #OTD in 1970, ready to launch astronauts Jim Lovell, Fred Haise, and Jack Swigert the following day on what was to be the third Moon landing mission. Two days into the mission, an oxygen tank on the spacecraft exploded, transforming Apollo 13 into a hair-raising rescue mission that hinged on the ingenuity and grit of the crew, mission control, and NASA engineers. To conserve their limited remaining power, the Apollo 13 crew was instructed to power down all non-essential systems and stay in the lunar module, which served as their “lifeboat” as they made their way back to Earth.
