SPACE VEHICLE HIGHLIGHT
All 16 Thruster Isolation Valve (TIV) electrical interfaces were successfully tested on the GP-B spacecraft using both A and B sides of the Attitude Control Electronics (ACE). The engineering unit TIV was connected to each interface and commanded to close and then open. The TIV open/close state was verified both visually and with EGSE.
