Alba Mons, tidigare även Alba Patera, är en vulkan på planeten Mars. Vulkanen ligger i Tharsisregionen på Mars, i den norra delen av området[1]. En av Alba Mons mest utmärkande drag är de ringformade gravsänkorna runt vulkanens topp. I öst-västlig riktning mäter Alba Mons ca 1400 km i diameter, medan den är cirka 1000 km i nord-sydlig riktning. Jämfört med andra vulkaner i området har den en ganska flack lutning, med en topp på 6845 meter. Eftersom Mars, till skillnad från Jorden, saknar hav så definieras 0 höjdmeter till ett atmosfäriskt tryck av 610.5 pascal[2].

Alba Mons MOLA zoom 64.jpg
Mars Orbiter Laser Altimeter (MOLA) colorized topographic map of the extremely broad, low-lying volcano Alba Mons in the northern part of the Tharsis volcanic province in the western hemisphere of Mars, together with its surroundings. The taller, more compact volcanoes Olympus Mons and Ascraeus Mons are at lower left and bottom center, respectively.

Mars Hubble.jpg
NASA's Hubble Space Telescope took the picture of Mars on June 26, 2001, when Mars was approximately 68 million kilometers (43 million miles) from Earth — the closest Mars has ever been to Earth since 1988. Hubble can see details as small as 16 kilometers (10 miles) across. The colors have been carefully balanced to give a realistic view of Mars' hues as they might appear through a telescope. Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap (top of image), and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere (lower right).
