Advanced Camera for Surveys Anomaly on Hubble Space Telescope

Summary
Hubble continues to operate normally, executing observations with the other three science instruments, WFC3, COS, and STIS, that are all performing nominally.
At 8:31 p.m. EST on February 28, 2019, the Advanced Camera for Surveys (ACS) aboard NASA's Hubble Space Telescope suspended operations after an error was detected as the instrument was performing a routine boot procedure. The error indicated that software inside the camera had not loaded correctly. A team of instrument system engineers, flight software experts, and flight operations personnel quickly organized to download and analyze instrument diagnostic information. This team is currently working to identify the root cause and then to construct a recovery plan.
