Rockets from various space missions. (For the Apollo moon missions they used a rocket called the Saturn V. They also used it for Skylab. Does your family have a big backyard drinking party to commemorate Skylab? Or is that just mine?)
There was even a Mars exploration display, which included the new Mars Curiosity rover. Which was featured in the Washington Post over Thanksgiving. (We had a hard time getting Jack to let go of the article.)
