Space Shuttle Endeavour is in the Samuel Oschin Pavilion at the California Science Center (700 Exposition Park Dr.), which is on the grounds of Exposition Park. Endeavour Together: Parts & People is one of the most popular exhibits at the California Science Center. All of the shuttles were largely built in California, so first off you peruse information panels and video displays telling the story of Endeavour's California birth. As for actual shuttle items, there is the orbiter's landing gear assembly (you're invited to touch the tires), the nose cone, a space toilet complete with entertaining video, and a portion of the shuttle's kitchen/galley accompanied by a video about eating in space. A small glass case displays some cool shuttle memorabilia (mission patches, photos, personal astronaut artifacts, etc.). There's also the original, actual Rocketdyne Operations Support Center, a mission control-type setup that was once at Rocketdyne headquarters in Canoga Park, Calif.
After you finish this exhibit, you're directed downstairs and out the museum's back door to the Samuel Oschin Pavilion, the huge, airplane hangar-like building that is the temporary home of Endeavour. Inside, Endeavour is mounted high above the floor in a horizontal flight position. On the floor directly beneath the shuttle are two circular banks of information panels with plenty of photos and info about the craft. In addition, the entire perimeter of the building interior is lined with displays. There are information/photo panels highlighting each and every single shuttle mission from 1981 to 2011. There's also a handful of video screens running short films specifically covering Endeavour and its missions.
