Apollo 13 (CONFIRMED • 2026)

For the crew, life went on. Ken Mattingly, who had been grounded by the measles, later flew on Apollo 16 and walked on the Moon. Fred Haise was slated to command Apollo 18, but the final three missions were canceled. He never got his lunar walk. Jim Lovell never flew in space again, though he remained with NASA for years.

Onboard, the crew felt a loud “bang” and a shudder that ran through the entire spacecraft. Warning lights exploded across the instrument panel. Swigert, his voice tight but professional, radioed the now-immortal words: “Okay, Houston, we’ve had a problem here.” (The 1995 film famously misquoted it as “Houston, we have a problem.”) Lovell quickly confirmed, “Houston, we’ve had a problem.” In Mission Control in Houston, the flight controllers initially dismissed the warning lights as a possible instrumentation glitch. But then the telemetry began to scream. Main Bus B voltage dropped to zero. Then Main Bus A followed. The fuel cells—the ship’s primary power source—began to fail one by one. The crew watched in disbelief as their primary supply of oxygen bled into space. Within two hours, both oxygen tanks were completely empty. Apollo 13

Gene Kranz, the legendary flight director, gathered his “White Team” in the Mission Control conference room. He famously didn’t pray; he made a list. The decision, made in a matter of minutes, was audacious: they would abandon the command module, power it down completely, and use the Lunar Module Aquarius as a “lifeboat.” Aquarius was designed to support two men for two days on the lunar surface. It now had to support three men for four days, traversing 200,000 miles of cold, radiation-soaked space. The ingenuity displayed over the next 86 hours remains a textbook example of engineering triage. Inside the LM, designed for a short hop on the Moon, the CO₂ levels began to rise perilously. The lithium hydroxide canisters that scrubbed carbon dioxide were square—designed for the command module. The LM’s system used round canisters. A mismatch meant death by asphyxiation. On the ground, engineers led by Ed Smylie threw together a makeshift adapter using only materials known to be onboard: a plastic bag, a cardboard cover from a flight manual, a roll of gray duct tape, and a suit hose. They radioed up the instructions. Astronaut Fred Haise, with the steady hands of a surgeon, assembled the “mailbox” in zero gravity. It worked. For the crew, life went on
