WEEKLY HIGHLIGHTS FOR WEEK ENDING 3 October 1997:
Speedring has completed the manufacturing of the primary flight quartz block, QB#3. All manufacturing operations and all process flow measurements have been successfully completed. A final verification to print under the supervision of a program quality assurance representative will be performed in early October.
SPACE VEHICLE HIGHLIGHT
All eighteen flight Helium thrusters have completed mechanical assembly and initial functional testing. The next thruster operations are building flight electrical harnesses onto the thrusters and acceptance and characterization testing. The automated characterization test setup has been successful run through a complete back pressure and temperature cycle with the engineering unit thruster in the thermal vacuum system in building 251. This system, which will save many person months of labor, autonomously collects massflow versus current data over the expected flight range of back pressures and temperatures.
