The U.S. was able to create and launch The Skylab that orbited the Earth. Scientists now had the ability to conduct experiments in a microgravity environment. This opportunity led us to understand our Earth and solar system in more detail than we ever could before. -
The Voyager Mission is so historic with many accomplishments across the board. These missions really allowed us to expand our horizons and learn about our outermost planets of the solar system. We got our first pictures of Saturn and Jupiter and learned more about these planets up close. -
