NASA's Jet Propulsion Laboratory Opens to the Public for Free This October
Explore JPL returns October 10 and 11 for the lab's 90th anniversary. Free tickets drop August 29 and disappear in minutes.
Explore JPL, the Jet Propulsion Laboratory's open house, returns Saturday October 10 and Sunday October 11, 2026, from 9:30 a.m. to 4 p.m., marking the lab's 90th anniversary. Admission and on-site parking are free, but entry is timed and ticketed, with a maximum of five tickets per reservation.
The real deadline is the ticket release: Saturday, August 29 at 9 a.m. PT, and JPL's own site cautions that based on previous years, tickets are expected to be fully reserved within 10 to 15 minutes. The route covers four themed zones plus the Space Flight Operations Facility, the Spacecraft Assembly Facility, the JPL Machine Shop and full-scale Perseverance, Voyager and Galileo models.
