There were four Deep Space Network (DSN) tracking passes during the past
week. The spacecraft performance remains normal.
On Monday, May 1, the first Interstellar Particle (ISP) Collection campaign
ended when the aerogel grid was successfully stowed. Telemetry from the
spacecraft verified the Wrist, Shoulder, and Hinge motors all performed as
expected. The Sample Return Capsule heat shield (cover) is in the cruise
position; closed, but not locked. This was performed with the Inertial
Measurement Unit’s (IMU) controlling the spacecraft attitude, since the
torque imparted by the cover movement exceeds the body rate capability of
the All Stellar mode.
Preparations are underway for our upcoming trajectory maneuver (TCM-3)
on May 24, and the acquisition of Navigation Camera images on May 25 while
the IMU’s are still on. Since this will be a small maneuver, the SRC cover
will be opened to demonstrate that a TCM can be performed in this state, as
will be required for the final two maneuvers at encounter with
Comet Wild-2 in 2004. This will provide performance data for those maneuvers
when the grid will be deployed.
