Mars is the fourth planet from the Sun and has characteristics that make it similar yet different from Earth. It has a thin atmosphere, seasonal changes, polar ice caps, the largest volcano in the solar system called Olympus Mons, and evidence of ancient rivers and lakes. Future missions are planned to further explore Mars, including the InSight lander in 2016 and Mars 2020 rover. The Curiosity rover has been exploring Gale Crater since 2012 and found environmental conditions that may have once supported microbial life.

3. Mars is the
fourth planet
from the Sun.
Second
smallest
planet in the
solar system.
The mass of
mars is
6.4×10^23kg.
Mars is referred
to as the RED
PLANET due to
its it’s red soil
made up of Iron
Oxide.
Orbits sun
every 687
days.
Average
surface
Temperature :
-53ºC
The
equatorial
radius of
Mars
3,397km.

6. MARS EARTH
1. Orbital period: 687 days.
2. Age: 4.503 billion years.
3. Moons: Phobos,Deimos.
4. Gravity: 3.711 m/s².
5. Density: 3.93 g/cm³.
6. Mass: 6.39 × 10^23 kg.
7. Distance from Sun:
227.9 million km.
1. Orbital period: 365 days.
2. Age: 4.543 billion years.
3. Moons: Moon.
4. Gravity: 9.807 m/s².
5. Density: 5.51 g/cm³.
6. Mass: 5.972 × 10^24 kg.

15. Liquid water cannot exist
on the surface of Mars due
to low atmospheric
pressure, which is about
100 times thinner than
Earth's, except at the
lowest elevations for short
periods.[ The two polar
ice caps appear to be
made largely of water.

19. Olympus Mons is
roughly three
times the height
of Mount Everest,
which in
comparison
stands at just
over 8.8 km
(5.5 mi).

20. In 2012, it was proposed
that Valles Marineris is
not just a graben, but
also a plate boundary
where 150 km (93 mi)
of transverse
motion has occurred,
making Mars a planet
with possibly a two-
plate
tectonic arrangement.

24. Of all the planets in the Solar
System, the seasons of Mars are
the most Earth-like, due to the
similar tilts of the two planets'
rotational axes.

27. Mass (kg): 10.8×1015
Orbital
period (h): 7.66.
Average moonrise period
(h, d): 11.12 h (0.463 d).

28. Mass (kg): 2×1015
Orbital period (h): 30.35.
Average moonrise period
(h, d): 131 h (5.44 d).

30. 25,000 years
from now. The
northern Martian
polar ice
cap could recede
as Mars reaches a
warming peak.
20–70 million
years from now.
Mars'
moon Phobos will
get close enough
to the surface to
be torn apart by
tidal stresses.
1.5–1.6 billion
years from now.
The Sun's
increasing
luminosity will
cause its
circumstellar hab
itable zone to
move outwards;
as the amount
of carbon
dioxide increases
in Mars's
atmosphere, its
surface
temperature will
rise to levels akin
to Earth during
the ice age.
7.5 billion years
from now. Earth
and Mars may
become tidally
locked with the
expanding Sun.

33. Planned for March
2016 is the launch
of
the InSight lander,
together with two
identical CubeSats
that will fly by
Mars and provide
landing telemetry.
The lander and
CubeSats are
planned to arrive
at Mars in
September 2016.
NASA plans to
launch its Mars
2020 astrobiology
rover in 2020.
Several plans for
a human mission to
Mars have been
proposed
throughout the
20th century and
into the 21st
century, but no
active plan has an
arrival date sooner

36. Curiosity is a car-
sized robotic
rover exploring Gale
Crater on Mars as part
of NASA's Mars Science
Laboratory mission
(MSL).[3] As of March 20,
2016, Curiosity has been on
Mars for
1287 sols (1322 total days)
since landing on August 6,
2012.
The rover's goals include:
investigation of the
Martian climate andgeology;
assessment of whether the
selected field site inside Gale
Crater has ever
offered environmental
conditions favorable
for microbial life, including
investigation of the role of
water; and planetary
habitabilitystudies in
preparation for future human
exploration.

37.  Curiosity's design will serve as the basis for the planned Mars 2020rover.
In December 2012, Curiosity's two-year mission was extended
indefinitely.
