Testing Einstein's Universe

WEEKLY HIGHLIGHTS FOR WEEK ENDING 26 March 1999:

STANFORD HIGHLIGHT
Under the direction of Dr. Doron Bardas the integration of the flight gyroscopes has begun. A non-flight gyroscope was successfully integrated and deintegrated to run through the integration process and to verify the adequacy of the process with regard to cleanliness. The first of four flight gyroscopes was successfully installed (gyroscope #3). The plan is to install the final three gyroscopes this week.
