WEEKLY HIGHLIGHTS FOR WEEK ENDING 23 July 1999:
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.
