Cape Canaveral, Florida -- NASA is renaming one of its most iconic buildings here in Florida after Neil Armstrong.
It's the building where every astronaut stays the night before their flight, where we see them walking out to go to the launch pad. That same building is also where the Apollo spaceships that took Americans to the moon were put together and tested.
NASA has announced that in a ceremony in two weeks, they'll rename that "Operations and Checkout" Building after Armstrong.
Armstrong became the first person to walk on the moon, 45 years ago, this month. He died in 2012.
His two fellow crew members from that Apollo 11 moon mission will be a part of the renaming ceremony on July 21st.
NASA's going to use the Armstrong Building to assemble the next American spaceship, named Orion. It's set for its first test flight later this year.
