Illustration of the Voyager spacecraft overlaid on a picture of Neptune that was taken by Voyager 2 less than five days before the probe’s closest approach of the planet on August 25, 1989. The picture shows the “Great Dark Spot” — a storm in Neptune’s atmosphere — and the bright, light-blue smudge of clouds that accompanies the storm. Credit: NASA/JPL-Caltech
NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>NASA’s Jet Propulsion Laboratory would be among the first to demonstrate that NASA’s new space shuttle could be used to conduct science experiments about our own planet from the vantage of space.

It is owned by NASA and managed by the California Institute of Technology (Caltech). The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA's Deep Space Network.

While the legendary Voyager 2 was in the midst of its triumphant Grand Tour through the outer planets, the space shuttle era was underway on Earth. NASA’s Jet Propulsion Laboratory would be among the first to demonstrate how NASA’s new shuttle could be used to conduct science experiments about our own planet from the vantage of space. But for launching missions to targets beyond Earth orbit, the shuttle posed engineering challenges. One mission that launched from the shuttle was Galileo, JPL’s flagship mission to Jupiter, and its route to the launch pad would be full of unexpected twists and turns.
Drawing on rare film footage as well as the memories of the engineers and scientists who were there, “The Footsteps of Voyager” recounts the dramatic experiences of these first-ever encounters at Uranus and Neptune and the efforts to deploy Galileo, a mission that would become the first to orbit an outer planet.
