On July 23, 1999, the Chandra X-Ray Observatory was placed in orbit by Space Shuttle Columbia STS-93. Chandra is a telescope designed to detect X-ray emission from very hot regions of the universe like exploded stars, clusters of galaxies, and matter around black holes. Join us for an an Air and Space Live Chat featuring astronaut Eileen Collins, who was commander of STS-93, and scientists who work with Chandra data.
Watch on this page or on Facebook Live on the National Air and Space Museum and STEM in 30 Facebook pages.
We’ll be hosting an Air and Space Live Chat on Facebook Live every Thursday at 1 pm EDT until the Museum reopens. Each week we’ll feature a different expert to answer questions from kids, students, and air and space enthusiasts.
We rely on the generous support of donors, sponsors, members, and other benefactors to share the history and impact of aviation and spaceflight, educate the public, and inspire future generations. With your help, we can continue to preserve and safeguard the world’s most comprehensive collection of artifacts representing the great achievements of flight and space exploration.
