Scientific paper

The Imager for Mars Pathfinder (IMP) camera[1] will be launched aboard the Pathfinder spacecraft toward Mars in December, 1996 for a July, 1997 arrival on the surface. Three windsocks were developed for attachment to the one-meter mast of the Atmosphere Structure Instrument/Meteorology (ASI/Met) package. The windsocks will be imaged repeatedly (with sub-framing and compression) over short intervals to allow measurement of the wind speed boundary-layer profile, including determination of aerodynamic roughness, wind friction speed, and shear stress on the surface due to wind. The ability to determine these parameters allows evaluation of the potential of wind to move fine particles across the landing site. Changes in the surface distribution of mobile materials during the mission can be related to aerodynamic roughness and friction speed determined from IMP windsock images. Surface changes and winds at the landing site might also be related to wind streaks and other albedo features within the landing ellipse seen in Viking Orbiter images.
