Why it matters: Caltech, which has managed JPL for NASA since 1958, is marking nine decades of the laboratory's space science and engineering work.

According to Caltech, the Jet Propulsion Laboratory traces its origins to experimental rocket-propulsion tests that Caltech graduate students, researchers and rocket enthusiasts began in Pasadena's Arroyo Seco on 31 October 1936.

Caltech said it has managed the laboratory for NASA without interruption since the agency was created in 1958.

Caltech said that the laboratory, then working under its management as a contractor for the US Army, launched Explorer 1, the first US satellite, on 31 January 1958, and that its Geiger counter detected the radiation belts surrounding Earth.

Caltech said JPL and the university are now looking towards the next near-century of innovation, discovery and exploration.
