Many astronomical phenomena viewed from the planet Mars are the same as or similar to those seen from Earth; but some (e.g. the view of Earth as an evening/morning star) are quite different. For example, because the atmosphere of Mars does not contain an ozone layer , it is also possible to make UV observations from the surface of Mars.

Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
The surface appearance of some regions of Mars is due to how this unit has degraded. It is a major cause of the surface appearance of lobate debris aprons. [56] The layering of the upper plains mantling unit and other mantling units are believed to be caused by major changes in the planet's climate.
Named after the Roman god of war, it is often referred to as the "Red Planet" [1] [2] because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere , having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth .
NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the launch of the two rovers to explore the Martian surface and geology ; both landed on Mars at separate locations in January 2004.
1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
