About Us
The San Diego Space Society (“SD Space”) was founded in 2008 with the purpose of raising awareness and educating the general public to the benefits of human exploration of space and San Diego’s role in space development, as well as to the idea of creating a spacefaring civilization within our lifetimes.
General meetings are held regularly at the Serra Mesa library, and SD Space members participate in many other local space events. Details of each meeting will be posted to the calendar. The general public is welcome to attend any meeting or event listed on this site.
SD Space is headquartered at the Space Travelers Emporium, a storefront and workshop in the South Park neighborhood.
If you have any questions about the San Diego Space Society, please email our general address: info@sdspace.org.
