THIS WEEK IN THE MARSHALL STAR: The core stage of NASA's Space Launch System passes its Critical Design Review (hurray!); a mysterious X-ray signal picked up by the Chandra X-ray Observatory has perplexed and intrigued astronomers; some key Marshall-managed programs are showcased in the latest video edition of "This Week@NASA"; and we say farewell to rocket scientist Fred Ordway, who passed away earlier this month at the age of 87. Ordway worked with Dr. Wernher von Braun during the early years of the Apollo program at Marshall, and later advised director Stanley Kubrick on the making of "2001: A Space Odyssey." Indeed, a life well lived! Read about his life, and much more, in this week's Star!
