Which module, designed for two astronauts for two days, had to sustain three men for a four-day return trip to Earth?
Answer
The Lunar Module (LM), Aquarius
When the Service Module suffered critical failure, the three astronauts—Lovell, Swigert, and Haise—were forced to evacuate the damaged Command Module and relocate into the Lunar Module (LM), designated *Aquarius*. The LM was originally engineered only to support two astronauts for approximately two days while on the lunar surface. Repurposing it to sustain three crew members for the significantly longer, four-day journey back to Earth presented an immense engineering hurdle, as its power and water reserves were never intended for such duration or load, demanding extreme rationing and improvisation.
