JPL: 90 Years of Cosmic Firsts & Future Frontiers
28 Oct
Summary
- JPL's journey began with rocket tests in 1936, evolving into a NASA contractor.
- Explorer 1, launched in 1958, discovered Earth's radiation belts.
- Future missions include lunar drones and Mars helicopters searching for ice.
Founded on October 31, 1936, by Caltech students experimenting with rockets, the Jet Propulsion Laboratory (JPL) now marks 90 years of innovation under NASA's management. Initially a contractor for the U.S. Army, JPL launched America's first satellite, Explorer 1, on January 31, 1958, which notably discovered Earth's radiation belts.
Since becoming NASA's only Federally Funded Research and Development Center in late 1958, JPL, managed by Caltech, has amassed a remarkable record. This includes the first U.S. Moon mission (Ranger 4), the first planetary flyby (Mariner 2 past Venus in 1962), and sending the first probe to visit all four gas giants (Voyager 2).
JPL continues to push boundaries with upcoming missions like SkyFall, set for launch in 2028 to search for subsurface ice on Mars. MoonFall aims to land propulsive drones at the lunar South Pole, while SunRISE (launching in 2027) will study solar activity with a unique satellite formation.
The Lab also focuses on Earth science, developing missions to track water movement, study tropical storms, and monitor air pollution. Additionally, NEO Surveyor is designed to detect potentially hazardous asteroids, enhancing planetary defense. JPL's contributions also extend to developing technologies like the 'camera on a chip' for cellphones.
As Voyager 1 approaches a "light-day" distance from Earth, nearing its 50th launch anniversary, JPL's legacy of discovery continues. Both Voyager probes, now in interstellar space, rely on JPL-developed Deep Space Network technology for communication, embodying the spirit of continuous exploration that began on a dry riverbed 90 years ago.
