Hubble Status Report
On June 22, at 12:21 PM EDT, the Cosmic Origins Spectrograph (COS) aboard Hubble temporarily suspended operations when an optical mechanism movement failed to reach its intended destination. The HST team quickly identified the root cause which required a minor update to the COS flight software. COS was successfully brought out of suspend mode on June 23. None of this week's scheduled COS activities have been lost.
On June 23, at 12:20 PM EDT, the Advanced Camera for Surveys (ACS) aboard Hubble suspended operations. No ACS commands were being executing at the time. A team has been formed to investigate the anomaly. ACS activities planned for this week are on hold.The team reports that the WFC3, STIS, and COS instrument activities are proceeding as planned.
