  • 3.  Mars is the fourth planet from the Sun in the Solar System  Named after the Roman god of War ,Mars  The "Red Planet" as the Iron Oxide prevalent on its surface gives it a Reddish Appearance  Mars is a terrestrial planet that consists of minerals containing silicon and oxygen, metals and other elements that typically make up rock.
  • 4.  Mars has two relatively small natural moons, Phobos and Deimos, which orbit close to the planet.  The motions of Phobos and Deimos appear very different from that of our own moon. Phobos rises in the west, sets in the east, and rises again in just 11 hours.  Despite the 30 hour orbit of Deimos, it takes 2.7 days to set in the west  Both have Circular Orbit
  • 5. Phobos Deimos
  • 6.  Mars is a terrestrial planet with a thin atmosphere, having surface features such as , the volcanoes, valleys, deserts, and Polar ice Caps.  Atmospheric pressure on the surface ranges from a low of 30 Pa(0.030 kPa) to over 1,155 Pa (1.155 kPa) with a mean pressure at the surface level of 600 Pa (0.60 kPa).  Methane has been detected in the Martian atmosphere with a mole fraction of about 30 ppb.  The atmosphere of Mars consists of about 95% carbon dioxide, 3% nitrogen, 1.6% argon and contains traces of oxygen and water.[
  • 7.  In the early ages it was supposed that the living thigs are present and life exist on Mars. But after the first Flyby this fact was cleared that there is no life on Mars.After that visit the theory failed.
  • 8. • The first successful flyby of Mars occurred in 1965, by Mariner 4 • Mariner 4 dipped less than 10,000 km above the planet's surface and took 22 pictures. Mars was covered with desert sand and ancient craters. No cities. No canals. No Martians. No one would ever look at the red planet the same way again.
  • 9.  Liquid water cannot exist on the surface of Mars due to low atmospheric pressure  This forms only in the presence of acidic water, which demonstrates that water once existed on Mars.
  • 10.  Early telescopic observations revealed that Mars has permanent ice caps at both poles; they're visible even with a small telescope. We now know that they're composed of water ice and solid carbon dioxide ("dry ice"). The ice caps exhibit a layered structure with alternating layers of ice with varying concentrations of dark dust.
  • 11.  As on Earth ,Mars also consists of minerals containing silicon and oxygen, metals, and other elements that typically make up rock.  Earth's crust, averaging 40 km, is only one third as thick as Mars’ crust, relative to the sizes of the two planets.  Size of Mars is much smaller than Earth.
  • 12.  So according to the scientific research it is proved that Mars is the planet after Moon in the Solar System where human life can be possible .  But under specific conditions.it can be possible because the traces of water and oxygen is present on Mars.
