WEEKLY HIGHLIGHTS FOR WEEK ENDING 31 October 1997:
Under the direction of Dr. William Bencze, Dr. David Manner, and Dr. Greg Gutt the Gyroscope Suspension System (GSS) CDR has been successfully completed on 10/23/97. This represents the last CDR of the payload electronics. The GSS has made significant progress since it has been chosen as the baseline GP-B suspension system in December 1996.
SPACE VEHICLE HIGHLIGHT
The Axial Lock automated test setup checkout is running in building 251. The axial lock redesign mechanisms will be tested in building 251 using this computer-controlled test bed. The system autonomously cycles the mechanisms at a constant rate and records running torque and screw position information for design evaluation of each unit. The system monitors torque, speed, rotation direction and position to stop testing if preset parameters are exceeded.
Initial thermal cycling and leak check of the Probe C flight fiber optic cables were completed this week. All three cables passed the post thermal cycling helium leak check with readings well under the 1x10-9 cc/sec requirement. All of the fiber optic qualification cable assembly work is finished and final thermal cycling sequence has been initiated.
