Planning on attending JPL Open House on Sunday? Please be aware that on Saturday the gates had to be closed early to all visitors, including walk-ins, due to the popularity of the event. By 8:00 a.m. traffic in the area was heavy; by 10:00 a.m. all parking lots were full. By noon, we could no longer accept walk-ins.

Please keep in mind Saturday’s experience if you intend visiting the lab on Sunday. Lines for exhibits will be long and temperatures will again be in the 90s. We recommend bringing water and wearing comfortable shoes. Food and drink is also available once you enter. The event is not recommended for the very young. A reminder there is no parking lot or entrance available on the east side of JPL off Windsor Ave. All vehicles and persons must enter via Oak Grove Drive.

Saturday, October 10 and Sunday, October 11, 2015

9:00 a.m - 4:00 p.m.

No tickets or reservations required.

NASA's Jet Propulsion Laboratory, Pasadena, California, invites the public to its annual Open House on October 10-11, 2015. The event is free of charge and takes visitors on a “ride” through the wonders of space. Highlights include a life-size model of Mars Science Laboratory, demonstrations from numerous space missions; JPL’s machine shop, where robotic spacecraft parts are built; and the Microdevices Lab, where engineers and scientists use tiny technology to revolutionize space exploration.

It’s not unusual for up to 20,000 people per day to come to JPL during our Open House. Our visitors have great experiences, but making your time here enjoyable may require patience — and planning. Here are some suggestions to get the most out of your day.
Photos and video clips will be posted after the event, so those who don't attend in person can get the flavor of the weekend.

  • Be sure to arrive early and be patient as there is only one entrance into JPL including a possible security check of your vehicle. Also, please note where you park.
  • Use your smartphone or tablet to try out JPL’s Open House web app to navigate the Lab. It provides real-time information on wait times at various sites, as well as directions to restrooms, food concessions, and other amenities.
  • The longest lines are usually at the Spacecraft Assembly Facility — the cleanrooms where we build spacecraft — and the Space Flight Operations Facility, where we communicate with all our missions. Keep this in mind if you want to include these sites in your visit.
  • Five movies will be shown throughout the day. The lines at these screenings can be shorter than other lines, and the movies offer a way to get off your feet in a cool place for a half hour while learning more about JPL missions.
  • Activities for young children are marked in the site listings. Do keep in mind that most experiences at JPL’s Open House are not intended for the very young.
  • Need help? Look for JPLers in bright red JPL-Caltech shirts with name tags. Information booths are also located around the Lab, as shown on the map.
  • Remember as you plan your visit that Open House ends at 4 p.m.

Vehicles entering NASA/JPL property are subject to inspection. Visitors cannot bring these items into NASA/JPL: weapons, explosives, incendiary devices, dangerous instruments, alcohol, illegal drugs, pets, all types of skates including skateboards, Segways and bicycles. No bags, backpacks or ice chests are allowed, except small purses and diaper bags. Drones are not allowed to fly over NASA/JPL under any circumstances.
