The national SaveChandra community honors the life and legacy of Dr. Martin C. Weisskopf, and we and mourn his loss deeply. He was NASA’s Chandra Project Scientist for 45 years, a founding visionary of the mission, and a titan of high-energy astrophysics. From the earliest days of the mission through decades of discovery, his brilliance will forever illuminate the dark universe. 

Ad astra, Martin.
