How did the Apollo 11 work?
How was the Apollo 11 powered?
In the Command and Service Modules, fuel cells were used to generate power. Apollo fuel cells used oxygen and hydrogen — stored as liquids at extremely cold temperatures — that when combined chemically yielded electric power for the spacecraft and, as a byproduct, drinking water for the astronauts.
How did Apollo 11 get back to Earth with no fuel?
The TLI placed Apollo on a "free-return trajectory" – often illustrated as a figure of eight shape. This course would have harnessed the power of the Moon's gravity to propel the spacecraft back to Earth without the need for more rocket fuel.
How did Apollo fuel cells work?
