On July 23, 1999, the Chandra X-Ray Telescope was launched into space aboard the shuttle Columbia, the first such mission to be commanded by a woman astronaut. The Chandra telescope differs from the Hubble telescope, which observes visible light. Or, the James Webb telescope, which captures frequencies in the infrared range. Chandra detects high energy X-rays. But NASA budget constraints could leave the mission going dark in coming years. To learn more about the Chandra Observatory, Marketplace’s Meghan McCarty Carino called its program manager Megan Lin.
