This NASA Hubble Space
Telescope view provides the
most detailed complete
global coverage of the red
planet Mars ever seen from
Earth.This picture was taken
on February 25, 1995, when
Mars was at a distance of 65
million miles.

15. Gigantic Canyon
Valles Marineris, or Mariner
Valley,

17. Atmosphere on Mars
 Mars has a rocky, dry terrain with huge volcanoes and deep
valleys.

22. Phobos
About 14 miles in diameter
Orbit close to the planet
Named after the character Phobos
(panic/fear)
Rises in the west, sets in the east, and
rises again in just 11 hours

23.  About 8 miles in diameter
 Named after the character Deimos
(terror/dread)
 Rises as expected in the east but very slowly
 30 hour orbit of Deimos, 2.7 days elapse between
its rise and set for an equatorial observer as it
slowly falls behind the rotation of Mars

26. Mariner missions In July of 1965, Mariner 4, transmitted 22 close-up pictures
of Mars. All that was revealed was a surface containing many
craters and naturally occurring channels but no evidence of
artificial canals or flowing water.

27. The First Rover
Mars Pathfinder

28. Spirit
Opportunity

29. In March 2005, Spirit studied rocks in the
“Paso Robles” area that have a high sulfur
content. Much of the high sulfur is
contained in a hydrated iron-sulfate
mineral that can only have formed in the
presence of liquid water.
Spirit

30. Opportunity
Opportunity’s spectrometer and
microscopic imager found that rocks
near the lower slopes of Endurance
Crater were affected by water both
before and after the crater formed.
