Today's third day of work on Hubble included installation of the Cosmic Origins Spectrograph (COS) and repair of the Advanced Camera for Surveys (ACS).
Our shifts on the ground have shifted an hour later to accommodate a revised crew sleep cycle. My shift is now 4:30 PM to 5:30 AM. While working this planning shift turns the body's sleep cycle upside down, there is an advantage in that there are more quiet moments.
During a quiet time, I can go upstairs in Building 30 to the 3rd floor and visit the old Apollo control room, where Apollo 11 videos run continuously day and night as sort of an 'eternal flame'. This allows a few moments to reflect on and celebrate the accomplishments of those pioneers (in space and on ground support) who went before us in opening this frontier.
