Stardust Status Report 01-14-2000
There were eight Deep Space Network (DSN) tracking passes in the past
week. Three of the eight passes were designated as “ranging only” passes.
That is, no telemetry was downlinked in order that the full carrier signal
strength could be used to obtain high resolution ranging data for
Navigation. During all passes the subsystems performance remained
normal.
The All-Stellar demonstration was repeated with the collection of high
rate attitude telemetry. This involved commanding the spacecraft’s
Star Camera to Track Mode, followed by 1.5 hours in Dual Mode. After
the Dual Mode was completed commands were transmitted to place the
spacecraft in All-Stellar mode. During the two hours in All-Stellar
mode, no multiple thruster firings were observed. Analysis of the data
is ongoing
Preparations for Deep Space Maneuver #1 (DSM-1) are well under way.
DSM-1 has a magnitude of 159.8 meters/second (m/s) and will be performed
in three equal times of 00:33:36. Part A will be performed on Tuesday,
January 18 at 11:00 am PST; Part B on Thursday, January 20 at 0600 am PST;
and Part C on Saturday, January 22 at 1000 am PST. The spacecraft will be
off Sun point and out of contact for approximately 60 minutes for each of
the burns.

Nebraska Christa McAuliffe Teaching Award.
