Astronauts make reaching for the stars look easy. But the truth is, science and space exploration are about trying, testing, making mistakes and trying again. “The NASA Experience,” a new exhibition at Chabot Space and Science Center in Oakland, captures the spirit of research and discovery by showing us the world through the eyes of NASA’s scientists and space crews. “The NASA Experience” features artifacts and activities for all ages, and it’s the highlight of Chabot’s reopening Friday that follows 18 months of construction.
