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 Facebook Live on the National Air and Space Museum Facebook page or on our website. 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. |
