Stardust Status Report
January 25, 2002
There were two Deep Space Network tracking passes during the past week
and all subsystems are normal.
Stardust successfully completed Deep Space Maneuver 2, the seventh
trajectory correction maneuver since launch. This maneuver corrected
errors from last year's Earth flyby.
All subsystems performed normally as the spacecraft turned away from the
Sun to perform the 2.65 meter/second burn.
The power subsystem has been performing even better than predicted when the
spacecraft must point away from the Sun -- its power source -- to
communicate with Earth or to maneuver. For a typical communications pass,
the battery's charge state goes from 107% to 85%. After the maneuver, the
battery's charge state, predicted to go down to 70 percent, had only
dropped to 95 percent before the spacecraft turned back toward the Sun and
the battery could recharge with solar power.
Currently, the solar panels are producing approximately 0.2 amps more than
Although the power performance margin indicates Stardust could have
additional communication time, we will continue to use a conservative
approach since Stardust is the first mission to use solar panels so far
from the Sun.
Stardust reaches the furthest point from the Sun in its orbit 2.72 AU in
mid-April and will exit Deep Space (2.4 AU) in late October of this year.
