Today was a busy day for the Endeavour crew. Today was the first of four planned spacewalks. This first EVA install the S5 truss segment which will support another set of solar arrays to be flown on a later flight. Today was also the first real test of the attitude control system -- the system that i manage. I'm happy to report that things went well. The control system did fairly well...there were a few tense moments but everything turned out okay.
We did have an unexpected failure today of the primary computer responsible for the command and control of the stations systems. But per design, the backup computer took control immediately following the failure of the primary. There was a small setback, but everything turned out okay.
Tomorrow, the Endeavour crew will inspect the belly of the orbiter to determine the extent of the damage. Early indications are that the gouge that was discovered will not need to be repaired, but the focused inspection that we'll do tomorrow will definitively tell us if we need to repair it.
The night ended with a Bldg M ops. Some of the flight controllers (the cool ones) and a flight director did a little socializing following our shift.
Also, tomorrow, we find out officially that we are extending the mission by at least an extra 3 days.
Tomorrow's color is blue.
