NASA JPL Looks to Next 90 Years of Innovation, Exploration

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Clockwise from top: Caltech graduate students and friends carry out their first rocket firing on Halloween, 1936, in a dry riverbed along which JPL would rise. Their work helped make possible missions such as Perseverance and Europa Clipper as well as the future SkyFall and MoonFall missions. NASA/JPL-Caltech Interstellar probes. Lunar drones. Helicopters on Mars. When a group of Caltech graduate students and enthusiasts began conducting rocket-propulsion tests in Pasadena’s Arroyo Seco on Oct. 31, 1936, they had no idea that their work marked the inception of the Jet Propulsion Laboratory. Ninety years later, the lab, now managed by Caltech for NASA, isn’t only celebrating the long line of historic firsts accomplished here; it’s paving the way for many to come. Initially a contractor for the U.S. Army, JPL launched America’s first satellite, Explorer 1 in 1958. But rather than just orbiting Earth like the Soviet Union’s Sputnik, Explorer 1 became the first spacecraft to conduct science, thanks to an onboard Geiger counter that discovered the protective radiation belts encircling Earth. The lab joined p
