Astronauts Neil Armstrong and Buzz Aldrin died about 50 years ago. On July 20, 1969, the first landing on the surface of the moon marked the beginning of a new era in human space travel. As Neil Armstrong said when he first landed on the moon, it was a small step for the moon, but a huge leap for the human race.
In order to do so, they had to give up some of the most immersive things on Earth. NASA engineers worked hard to launch their American astronauts on the moon, but did not build toilets on their Apollo missions in the 1960s and 1970s.
