The "Meteorology Mast" - MET - Sol 33 (Enhanced Natural Colors; credits: NASA/JPL)

Caption NASA originale:"The Mars Pathfinder Meteorology Mast casts a shadow on the Lander Solar Array, as seen in this superpan mosaic. Looking to the South/East during the morning, the windsocks are slightly tilted, indicating the presence of a light wind from the South/West. The MET mast measured the temperature, pressure and wind speed at the Pathfinder Landing Site. During the mission, the instrument returned 8,5 million individual measurements from the Surface of Mars".
