Chandra's Exceptional Performance Amid Proposed Budget Reductions

The Chandra X-ray Observatory is operating with exceptionally high efficiency and continues to revolutionize our understanding of the universe and our place in it, including capturing spectacular images of exploded stars, black hole eruptions and other exotic phenomena. While all spacecraft experience degradations, particularly after being in space for nearly 25 years like Chandra has, Chandra scientists and engineers have continued creating solutions to these challenges, an achievement that has been recognized by NASA and independent review panels. This has been done essentially without any increased costs to NASA. Chandra is the only current or planned telescope for many years that has the sharp X-ray vision needed to answer many fundamental questions in astrophysics.
