Hanging out on the Moon
The first moon landing in 1969 didn’t even last three hours—but when the Eagle landed and and Neil Armstrong and Buzz Aldrin became the first men on the moon, they sure fit in some awesome stuff. They planted an American flag, performed a couple of experiments (including trying out different ways of moving in low-gravity), took photographs and some film, and collected 22 kilograms of rocks and soil for study back on earth. They also installed retroflectors, which are devices that reflect light back its source with minimum scattering, so that we on Earth could reflect light off the moon. Over the following years and further Apollo missions, astronauts had even more fun—whole days were spent on the moon, golf balls were hit to demonstrate the low-g environments, and on the Apollo 15, 16, and 17 missions, astronauts even drove a battery-powered “moon buggy” around the lunar service. Apollo 17 in 1972 was the last mission to the moon, and so amazingly, no one has been there since—imagine all the cool things we could have done if we’d had 40 more years on the moon.
