Entering the hatch is astronaut Virgil I. Grissom, command pilot; behind him is astronaut Roger B. Chaffee, pilot; standing at the left with chamber technicians is astronaut Edward H. White II, senior pilot.
context_page_description: The Neil Armstrong Operations and Checkout Building is a historic building on Merritt Island, Florida, United States. The five-story structure is in the Industrial Area of NASA's Kennedy Space Center. Its facilities include the crew quarter dormitories for astronauts, and suit-up preparations prior to their flights. The other facility is a large spacecraft workshop used for manufacturing and checking activities on crewed spacecraft. On January 21, 2000, it was added to the U.S. National Register of Historic Places.
context_section_description: In 1965, a pair of altitude chambers were installed in the High Bay for testing the environmental and life support systems of both the Apollo Command/Service Module and Lunar Module at simulated altitudes of up to 250,000 feet (76 km). Each chamber is 58 feet (18 m) high (with a clear working height of 28 feet (8.5 m)) and an interior diameter of 33 feet (10 m), were human-rated, and capable of reaching the maximum altitude (minimum pressure) in one hour. These were used by the prime and backup crews of all crewed missions, from the ill-fated Apollo 1 in October 1966, through to the Apollo-Soyuz Test Project in July 1975.
