The Smithsonian has extended its “American Aspirations” exhibition at the Castle through Monday, Aug. 10, giving visitors several additional days to see the 30-object show before the institution marks its 180th anniversary.
The exhibition was scheduled as part of programming for the United States’ 250th anniversary. Its revised closing date now aligns with the Smithsonian’s own anniversary, which falls on Aug. 10.
Objects from multiple Smithsonian museums are organized around seven pursuits: liberty, democracy, fairness, hope, progress, new horizons and defending freedom. The framework places artifacts from different eras in one compact exhibition rather than treating them as a single chronological collection.

The founding-era group includes Thomas Jefferson’s portable desk, used while drafting the Declaration of Independence, and George Washington’s candlestand, associated with work on his Farewell Address. A model of the Statue of Liberty represents another stage of national symbolism.
Aviation and space objects extend the story into the 20th century. The Smithsonian specifically names Amelia Earhart’s flight suit and Sally Ride’s spacesuit among the items on view.
Computing is represented by a component from ENIAC, an early general-purpose electronic computer. Its inclusion makes technological capability part of the exhibition’s account of American aspirations rather than a separate science display.

The show is installed in the Smithsonian Castle, the institution’s oldest building and symbolic center. Completed in 1855, the Castle originally combined museum, library and administrative functions.
The building reopened during a temporary pause in its larger revitalization project. Visitors can also see the restored Great Hall and interpretive material about the Castle; the Smithsonian says the building itself will remain open through Sept. 7.
The extension is short and specific: through Aug. 10, not through the Castle’s September closing. The Smithsonian reports thousands of visitors but gives no exact attendance count, so the durable public facts are the 30 objects, seven themes and anniversary-linked final date.
