08.18.09 - Hubble is getting closer to completing the calibrations for most of its instruments, and each day it draws nearer to becoming a fully functioning observatory again. In fact, in the upcoming weeks, Hubble will concentrate on making high-priority science observations and then finish the remaining instrument calibrations by early fall.
08.07.09 - As the first week of August comes to a close, most of Hubble’s science instruments have already completed or are close to completing their calibration activities. Each instrument has multiple channels that detect different wavelengths of light, and each channel must be tested and calibrated individually. While some instrument channels are still under evaluation, several others are already at work studying the universe.
08.05.09 - Hubble engineers are encouraged by the recent restart attempt of an instrument that has been inoperable since Sept. 10, 2008.
07.31.09 - After a quick detour into taking science observations, Hubble is back to alignment and calibration activities. Each instrument has a number of channels that detect and process different wavelengths. Some of these channels have been approved for science observations at this point, others are still works in progress.
07.29.09 - The HST tiger team continues their investigation of a problem with the Space Telescope Imaging Spectrograph (STIS) that caused it to suspend operations on July 6.
07.23.09 - The HST tiger team continues their investigation of the Space Telescope Imaging Spectrograph (STIS) anomaly which caused it to suspend operations on July 6. The team presented their status to the HST Project on July 20, and a recovery plan was approved.
07.20.09 - During Servicing Mission 4, astronauts replaced many key parts batteries and gyroscopes, for example that affect the spacecraft component of the Hubble Space Telescope. Testing and calibration for the spacecraft itself is now complete, and that aspect of Hubble is in excellent shape.
07.10.09 - Since the conclusion of Servicing Mission 4, engineers and scientists have been conducting the painstaking process of testing and reactivating Hubble components in order to bring the telescope back to full science operations.
07.13.09 - The HST team continues to investigate an anomaly with the Space Telescope Imaging Spectrograph that caused it to suspend operations on July 6. An attempt to fully recover the instrument on July 10 was not successful.
07.02.09 - The HST team investigating the Advanced Camera for Surveys (ACS) anomaly presented findings and recommendations to the HST project on June 30 that included a plan to bring the instrument out of suspend mode later this week.
