Description:
The Halley Optical Probe Experiment (HOPE) will furnish in situ photopolarimetric data on Comet Halley's coma dust cloud and atmosphere. The optical probe concept involves measurements of the polarized spectral radiance in the direction of motion at two points on the spacecraft trajectory, parallel to the direction of motion; their difference is the spatial derivative of the radiance along the line-of-sight, as well as of the light scattered by dust or emitted by gas in a tube along the trajectory. HOPE is proposed for the Giotto spacecraft's flyby of Comet Halley.
