INTRODUCTIONINTRODUCTION
Mars is the fourth planet from the sun and the second Mars is the fourth planet from the sun and the second smallest planet in the solar, after Mercury. Named smallest planet in the solar, after Mercury. Named after the Roman god of war, it is often described as the after the Roman god of war, it is often described as the “Red Planet" because the iron oxide prevalent on its “Red Planet" because the iron oxide prevalent on its
surface gives it a reddish appearancesurface gives it a reddish appearance

TELESCOPE PICTURE OF MARSTELESCOPE PICTURE OF MARS
This NASA Hubble Space Telescope This NASA Hubble Space Telescope view provides the most detailed view provides the most detailed complete global coverage of the red complete global coverage of the red planet Mars ever seen from Earth. planet Mars ever seen from Earth. This picture was taken on February This picture was taken on February 25, 1995, when Mars was at a 25, 1995, when Mars was at a distance of 65 million miles.distance of 65 million miles.
Does Mars have an atmosphere?Does Mars have an atmosphere?
The atmosphere is much thinner than Earth’s and is comprised primarily of carbon dioxide and nitrogen. It’s gravity is about one-third of our own.
The largest volcano in the solar system is Olympus Mons. It is 624 km (374 miles) in diameter; about the same size as Arizona.The altitude of Olympus Mons is three times the altitude of the largest peak on Earth, Mt. Everest.
LARGEST VOLCANO ON MARSLARGEST VOLCANO ON MARS
The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.
What Is the Distance Between Earth and Mars?
Seasons on MarsSeasons on Mars
Like Earth, Mars has seasonal changes but the seasons last much Like Earth, Mars has seasonal changes but the seasons last much longer. In Winter, Mars’ polar ice cap can reach down to 45 degrees longer. In Winter, Mars’ polar ice cap can reach down to 45 degrees latitude and then rapidly shrink during Spring. Dust storms are latitude and then rapidly shrink during Spring. Dust storms are seasonal, also, as witnessed in this Hubble image.seasonal, also, as witnessed in this Hubble image.

Moons of MarsMoons of Mars
• Mars has two tiny moons named “Deimos” (Panic) & “Phobos” (Fear)
• The moons are irregular and very small in size– Phobos 27x22x18 km– Deimos 15x12x10 km
• The moons are probably asteroids captured by Mars
Deimos Phobos
Curiosity RoverCuriosity RoverCuriosity is a car-sized robotic rover exploring Gale Crater on Mars as part of NASA's Mars Science Laboratory mission (MSL).Curiosity was launched from Cape Canaveral on November 26, 2011, at 10:02.It landed on in Gale Crater on Mars August 6, 2012,

The Mars Orbiter Mission (MOM), also called Mangalyaan is a spacecraft orbiting Mars since 24 September 2014. It was launched on 5 November 2013 by the Indian Space Research Organization (ISRO).
It is India's first interplanetary mission and ISRO has become the fourth space agency to reach Mars.
