The SMUD Museum of Science and Curiosity, better known as MOSAC, is Sacramento’s science center, set on the Sacramento River at 400 Jibboom St. in a restored early-1900s brick power station just north of Old Sacramento. Families and educators come for hands-on STEAM exhibits that tie science to local and global issues like energy, health, and water (source: [MOSAC](https://visitmosac.org/)).
The museum reopened in November 2021 after a full modernization and renovation (source: [Sacramento Area Museums](https://www.sacmuseums.org/museums/smud-museum-of-science-and-curiosity)). Inside, the industrial shell holds interactive galleries where kids test ideas rather than read placards. A domed planetarium hosts sky and space shows. Beyond weekend visits, MOSAC runs after-school and summer programs and positions itself as a regional hub for science education and workforce development.
Visitor Highlights & Practical Info
The City of Sacramento operates the museum’s parking lot and charges $6 per day. You can pay at the kiosk out front or through ParkMobile using location code 6848 (source: [MOSAC Visit](https://visitmosac.org/visit/)). School field trips fill weekday mornings, so weekday afternoons are usually calmer. Expect weekends and school breaks to be busiest. Reserve tickets and planetarium shows online, and confirm current hours before you go. Afterward, walk the riverfront trail south to Old Sacramento’s historic waterfront, or head north toward Discovery Park and the American River Parkway.
