Mars' Satellite Deimos
Craters And Streaks

Close-up image of Mars' satellite Deimos from the Viking 2 Orbiter showing craters and associated streaks. The streaks run from upper right to lower left, and may have been formed by the base surge "wind" of an impacting meteoroid. The image is about 1.3 km across and north is at 11:30. (Viking Orbiter 423B62)
