This composite of red and blue
Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC)
daily global images acquired on 6 July 2005
shows an isolated water ice cloud extending more than
30 kilometers (more than 18 miles) above the martian
surface. Clouds such as this are common in late
spring over the terrain located southwest of the
Arsia Mons volcano. Arsia Mons is the dark, oval
feature near the limb, just to the left of the “T”
in the “Tharsis Montes” label. The dark, nearly circular
feature above the “S” in “Tharsis” is the volcano,
Pavonis Mons, and the other dark circular feature,
above and to the right of “s” in “Montes,” is
Ascraeus Mons. Illumination is from the left/lower left.
