How cold did it get in the Aquarius capsule of the Apollo 13 mission?

During the Apollo 13 mission, the temperature in the Aquarius lunar module dropped to around 38 degrees Fahrenheit (3 degrees Celsius) due to the loss of power and life support systems after an oxygen tank explosion. This drop in temperature posed significant challenges for the astronauts, as they had to conserve energy and manage their limited resources while navigating back to Earth. Despite the harsh conditions, the crew successfully returned home safely.
