Dynamic Science

NSSDC ID: 1999-003A-04
Mission Name: Stardust/NExT
Principal Investigator: Dr. John D. Anderson

Description

The Dynamic Science investigation has two parts. The radio science portion will make use of the X-band telecommunications system to constrain the limits of the mass of the nucleus of Wild 2 by using measured Doppler frequency shifts in the coherent two-way X-band signal to estimate the motion of the spacecraft and the effect of the gravity field of the nucleus on the spacecraft. The other portion of the investigation involves use of the inertial measurement unit in the attitude control subsystem to estimate the magnitude of the large particle impacts and integrated dust flux.
