Insight... into the early evolution of terrestrial planets.
RISE (Rotation and Interior Structure Experiment)
  • RISE uses the lander's X-band radio link for Doppler tracking of the lander's location with an accuracy of a handful of cm.
  • Since the lander is attached to the planet, this allows the measurement of the rotation of Mars, and particularly variations in its rotation axis.
  • These rotational variations are related primarily to the size and state of the core, through its effect on the moment of inertia and damping of Mars.
  • Science team led by JPL.
