Mishaps of the Space Age
1970: Apollo 13
En route to the moon, Apollo 13 suffered an explosion and lost its main
power supply. Abandoning the mission, ground controllers in Houston then had to
figure out a way to get the three astronauts, Jim Lovell, John Swigert, and
Fred Haise, back home. Remarkably, they devised a way to send the stricken
craft, with the threesome aboard the lunar lander, around the moon, using the
latter's gravity field to shoot the spacecraft back toward Earth.

But the procedure was highly risky. With only a two-day battery supply to
power their four-day trip home, the crew had to shut down all non-vital
equipment, including their computer and climate control systems. While the
lander contained an ample supply of oxygen, it did not have enough canisters of
lithium hydroxide to remove the carbon dioxide exhaled by the crew. The main
spacecraft had additional canisters, but these wouldn't fit into the lander's
housing unit. In essence, the lives of Apollo 13's crew depended on finding a
way to fit a square peg into a round hole.

| Again, Ground Control in Houston came through. Aware of the materials on
board, they designed a makeshift adapter from the covers of flight-plan books,
plastic bags, and duct tape, and the crew eventually returned safely to
Earth.
