Chandra X-ray Observatory

NASA's Chandra X-ray Observatory is an active Great Observatory studying the high-energy universe with exceptionally sharp X-ray imaging and spectroscopy. Columbia launched it on STS-93; IUS-27 and Chandra's own propulsion system placed it into a long-period highly elliptical Earth orbit, where SAO conducts flight and science operations for NASA.

Description
NASA's Chandra X-ray Observatory is an active Great Observatory studying the high-energy universe with exceptionally sharp X-ray imaging and spectroscopy. Columbia launched it on STS-93; IUS-27 and Chandra's own propulsion system placed it into a long-period highly elliptical Earth orbit, where SAO conducts flight and science operations for NASA.
Destination
Highly elliptical Earth orbit with an approximately 64-hour period (initially about 10,000 × 140,000 km perigee/apogee; orbit evolves over time) for high-resolution X-ray observations of the universe
Launch Site
Outcome
Active and highly successful. Chandra exceeded its planned five-year lifetime many times over and continues returning high-resolution X-ray observations that support research on black holes, supernova remnants, galaxy clusters, stellar evolution, and other energetic phenomena.
