The Jet Propulsion Laboratory is a federally funded research and development center and NASA field center in La Cañada Flintridge, California, United States, though it is often referred to as residing in Pasadena, California, because it has a Pasadena ZIP Code.
Founded in the 1930s, the JPL is currently owned by NASA and managed by the nearby California Institute of Technology for NASA. 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.
The center offers guided tours and also hosts open days (check the website for the dates).
The tours run approximately once per week on Monday or Wednesday on an alternating basis. Visitor Day Tours are generally held at 1:00 p.m.
Free, but must be booked in advance at least 3 weeks prior.
