Galileo was an unmanned NASA spacecraft which studied the planet Jupiter and its moons, as well as several other solar system bodies. Named after Renaissance astronomer Galileo Galilei, it consisted of an orbiter and entry probe. It was launched on October 18, 1989, carried by Space Shuttle Atlantis on the STS-34 mission. Galileo arrived at Jupiter on December 7, 1995, after gravitational assist flybys of Venus and Earth, and became the first spacecraft to orbit Jupiter. It launched the first probe into Jupiter, directly measuring its atmosphere. Despite suffering major antenna problems, Galileo achieved the first asteroid flyby, of 951 Gaspra, and discovered the first asteroid moon, Dactyl, around 243 Ida.
Mound Laboratories in Miamisburg, Ohio was an Atomic Energy Commission (later Department of Energy) facility for Nuclear weapon research during the Cold War.
The laboratory grew out of the World War II era Dayton Project (a site within the Manhattan Project) where the neutron generating triggers for the first plutonium bombs were developed.
