Stardust Status Report
June 6, 2003

The Stardust team had a half dozen periods of communication with the 
spacecraft in the past week. Telemetry relayed from the spacecraft 
indicates it is healthy and all subsystems continue to operate normally.

The Spacecraft Test Laboratory continues a series of test cases designed to 
stress the spacecraft's Attitude Control Subsystem. These tests are 
performed in the Spacecraft Test Laboratory and, at present, are exercising 
the spacecraft's "bang-bang" controller. The "bang-bang" controller is the 
name for the attitude control strategy the spacecraft will use while inside 
the coma of Comet Wild 2. The controller has the authority to engage 
Stardust's primary and secondary thrusters in the event of a large dust 
particle impact on the spacecraft.

Information on the present position and orbits of the Stardust spacecraft 
and comet Wild 2 may be found on the "Where Is Stardust Right Now?" web 
page located at:
