Minor Hubble Glitch

NASA Hubble Space Telescope Daily Report # 4470


Gyro 2's second flex lead failed on DOY (278) 10/05/07. An increase in the gyro's heater duty cycle from 10-12% to 26-38% revealed that additional heater power was compensating for the absence of motor current.

The second flex lead failure was expected. The first flex lead failed on August 31, 2007, after which Gyro 6 was turned on. The second flex lead's failure did not impact HST's operation."
