NASA's Mars Global Surveyor shows a streak formed by wind in the lee of a meteor impact crater on Mars.

MGS MOC Release No. MOC2-401, 24 June 2003

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a streak formed by wind in the lee of a meteor impact crater. The winds responsible for the streak and the numerous smaller "tails" behind small obstacles all indicate that regional winds blow from the right/upper right (northeast) toward the left/lower left (southwest). The crater is located near 13.7°S, 131.5°W. Sunlight illuminates the scene from the left/upper left.
