We’re all about space! Join us for Cal Day, Saturday, April 13th, from 11am-5pm, the one day each year that the Space Sciences Lab at UC Berkeley opens its doors to the public. Shuttles will be transporting the public every 20 minutes or so from Hearst Mining Circle on campus to Space Sciences Lab (the last stop after Lawrence Hall of Science).  Activities include walking tours of UC Berkeley’s cutting-edge space science research lab, as well as talks on current research and hands-on activities for all ages!

Walking Tours

(11:00 am – 4:00 pm) See UC Berkeley’s cutting-edge space science research lab. Learn about the illustrious 50-year history of NASA missions, visit our 60′ high bay, the cosmochemistry laboratories that analyzed lunar samples, peek into our Mission Operations Center from which we operate six NASA satellites, and more. Tours start at 11 am and leave every half hour to 4:00 pm. Each station will have someone to explain what you want to know. Last tour 4:00 p.m.

Tech Talks

20-minute talks on current research, technology, and NASA missions, taking place on the hour from 12-3 pm (12 noon, 1:00, 2:00 and 3:00).

Our Space Missions (narrated slide show)

The history of Space Sciences Lab and the missions that were worked on here through science, instrumentation, or data analysis.


(inside and outside 11 am -5 pm)

  • Machine shop — Visit our machine shop where we build instruments and parts that go into space! It takes a special shop to build things for space.
  • Solar telescope (weather permitting) — Look at our Sun through specially -filtered telescopes and you may see solar activity such as flares, prominences and sunspots.
  • Activity tables, such as one featuring ICON, our latest satellite mission, which will include a life-size ICON payload model, videos, activities and giveaways. Watch a microwave activity using grapes that will demonstrate how one of our Parker Solar Probe instruments works.
  • For kids — Sun-Earth Game, space-related chalk drawing in the lot (weather permitting).
