WEEKLY HIGHLIGHTS FOR WEEK ENDING 23 July 1999:
STANFORD HIGHLIGHT
The residual magnetic field in the SMD (Science Mission Dewar)
lead shield has been re-measured.
The magnetic field is unchanged within measurement error from that prior to
the subatmospheric operations. Thus the residual magnetic field still meets
its requirement. The work has been performed by Dave
Murray, John Mester, Mike Taber, and Tom Welsh.
The prototype units of the GP-S receiver and antenna have succesfully
passed vibration testing. The GPS group is composed of Awele Ndili, Dave
Yale, and Gerry Murphy.

SPACE VEHICLE HIGHLIGHT
The two Relativity Mission qualification thrusters have completed a full
life of testing (2 years, 1.1+ million cycles), successfully completed their
functional flow check, and have started on their second life.
