NASA’s Explorer 9 satellite launched from the Wallops Flight Facility in eastern Virginia.
The satellite looked like something straight out of a science fiction film, as it was a giant 12-foot (3.66 m) metallic sphere covered in white dots to aid thermal control. The purpose of Explorer 9 was to study the composition and density of Earth’s lower exosphere and upper atmosphere. It was the first spacecraft to launch successfully from the Wallops Flight Facility and the first to reach orbit atop a launch vehicle that only used solid fuel.
