Armstrong Operations and Checkout building at NASA's Kennedy Space Center in Florida. The altitude chamber simulates deep space vacuum conditions, and the testing will provide additional data to augment data gained during testing earlier this summer. The Orion spacecraft will carry NASA astronauts Victor Glover, Koch, and Wiseman, as well as Hansen, on a 10-day journey around the Moon and back for the Artemis II test flight.
