Many of the strategies surrounding the Cold War revolved around two things: nuclear weapons and rockets. And in the United States, the Jet Propulsion Laboratory, under the supervision of Caltech, was charged with building America’s first tactical nuclear rockets: the Corporal and Sergeant missiles.

At this same time the United States and the Soviet Union were nearing the ability to launch a satellite into Earth orbit. JPLThe Jet Propulsion Laboratory (JPL) is a federally funded research and development center that was established in 1936. 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. JPL implements programs in planetary exploration, Earth science, space-based astronomy and technology development, while applying its capabilities to technical and scientific problems of national significance.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>JPL, working in collaboration with Wernher von Braun’s rocket efforts for the U.S. Army, believed they were fully capable of the feat, if only given the chance. That opportunity vanished in October 1957 when the Soviet Union shocked the world with the launch of Sputnik, the world’s first satellite. The Space Age was underway. The first U.S. response exploded on the launch pad. Only after that embarrassment were JPL and von Braun’s group given the green light. The success of Explorer 1, a satellite built by JPL, provided the world with the first space science discovery.

Explorer 1 traces the story of the role JPL played before the creation of 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 and how the lab was given a vital role as part of this new organization: to explore the cosmos.

“Explorer One” is Episode 2 in the documentary series “JPL and the Space Age.”

Explorer 1 was the first American satellite. It was launched on January 31, 1958 by the Jet Propulsion Laboratory (JPL). The satellite was part of the United States’ efforts during the Cold War to match the Soviet Union’s early successes in space exploration. The satellite’s mission was to measure radiation levels in Earth’s upper atmosphere, and it discovered the Van Allen radiation belts. JPL was the laboratory that built and operated the spacecraft.
