Stardust Status Report
February 23, 2001
There were fifteen Deep Space Network (DSN) tracking passes in the past
week and all subsystems are performing normally.
A test to determine the capacity of the battery was successfully
performed. Power will be limited at the next aphelion in April 2002, when
Stardust will be 2.72 AU, about 408 million kilometers, from the Sun.
Therefore knowledge about the battery's performance is needed now to plan operations
around aphelion. The test commanded a low charge rate for approximately
twenty-four hours to determine what pressure the battery reached at its
maximum charge capacity. Data from this test will be used to establish new
operating parameters starting when the spacecraft reaches approximately 2.4
AU from the Sun, in October 2001.
