The Museum of Natural History & Science at the Cincinnati Museum Center is offering free admission through Labor Day in honor of Neil Armstrong.
Museum officials say more than 2,000 visitors viewed the exhibit at the museum Sunday, the day after Armstrong's death.
Armstrong, the first man on the moon, died Saturday in Cincinnati at 82. The Ohioan commanded the historic landing of the Apollo 11 spacecraft on the moon on July 20, 1969.
Armstrong chose the Cincinnati museum to receive a moon rock from his Apollo 11 mission. The rock is on permanent display with replicas of Armstrong's Apollo 11 space suit and tools.
