MISSION TO MARS
THE RED PLANET

2. CREATED BY: SIFATUL ALAM SHOHAN

3. TOPICS TO BE DISCUSSED
What is Mars?
What is Mars like?
First images of Mars
Mars Facts
Mars Basics
Compareto Earth
Marsprobe Highlights

4. MARS IS THE FOURTH PLANET FROM THE SUN AND THE SECOND-
SMALLEST PLANET IN THE SOLAR SYSTEM, AFTER MERCURY. ITS THE
CLOSEST PLANET FROM THE EARTH.
MARS IS KNOWN AS THE RED PLANET.
MARS IS THE FOURTH PLANET FROM THE SUN AND THE
SECOND-SMALLEST PLANET IN THE SOLAR SYSTEM, AFTER
MERCURY. NAMED AFTER THE ROMAN GOD OF WAR. ITS
THE CLOSEST PLANET FROM THE EARTH.
MARS IS KNOWN AS THE RED PLANET.

5. WHAT IS MARSLIKE?
Its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it.
Red dust covers most of its surface. Mars has clouds and wind just like Earth.
Mars’ atmosphere is much thinner than Earth’s. The atmosphere of Mars contains
more than 95 percent carbon dioxide and much less than 1 percent oxygen.

6. FRIST IMAGES OF MARS
NASA'S HUBBLE SPACE TELESCOPE TOOK THIS
PICTURE OF MARS AS IT WAS MAKING ITS CLOSEST
APPROACH TO EARTH IN 60,000 YEARS!.
TAKEN BY THE VIKING 1 LANDER SHORTLY AFTER IT
TOUCHED DOWN ON MARS, THIS IMAGE IS THE FIRST
PHOTOGRAPH EVER TAKEN FROM THE SURFACE OF
MARS. IT WAS TAKEN ON JULY 20, 1976.

7. MARS FACTS
• 4th planet from the sun.
• Martian moons

8.  Mars distance from
the earth is 54 million
km.
Mars distance from
the sun is 227 million
km.

9.  EARTH’S VOLUME
IS SIX TIMES HIGHER
THAN MARS
 EARTH’S MASS IS TEN
TIMES HIGHER THAN
MARS

10. GRAVITY OF MARS
Gravity of Mars is 3.711 m/s²
Mars gravity is 62.5% less
than Earth.

11. Mean Radius: 6,371 km 3,396 km
Mass: 59.7×1023 kg 6.42 x 10²³ kg
Volume: 10.8 x 1011 km3 1.63 x 10¹¹ km³
Gravity: 9.8 m/s² 3.711 m/s²
Avg. Temperature: 14°C (57.2 °F) -46 °C (-51 °F)
Length of Day: 24 hours 24h 40m
Length of Year: 365.25 days 686.971 days
Water: Plentiful Intermittent (mostly frozen)
Polar Ice Caps: Yep Yep
COMPARE TO
IN SHORT, COMPARED TO EARTH, MARS IS A PRETTY SMALL, DRY, COLD, AND DUSTY PLANET. IT HAS
COMPARATIVELY LOW GRAVITY, VERY LITTLE ATMOSPHERE AND NO BREATHABLE AIR. AND THE YEARS ARE ALSO
MIGHTY LONG, ALMOST TWICE THAT OF EARTH, IN FACT. HOWEVER, THE PLANET DOES HAVE ITS FAIR SHARE OF
WATER (ALBEIT MOSTLY IN ICE FORM), HAS SEASONAL CYCLES SIMILAR TO EARTH, TEMPERATURE VARIATIONS
THAT ARE SIMILAR, AND A DAY THAT IS ALMOST AS LONG.

12. MARS BASICS
Similar to
Earth: day,
seasons,
polar ice caps
Different: dry,
cold, thin
atmosphere
(CO2)

16. When human will put their first step on mars
• NASA’S GOAL IS TO SEND HUMANS IN THE
RED PLANET BY 2030S.

17. REASONS TO GO:
• Overpopulation and limited resources on Earth
• Climate change
• Ensure the future of human civilization
• Create a backup location for humanity
• Colonization in another planet
• Discovering life on Mars

18. CAN HUMAN REALLY SURVIVE ON MARS??
 To survive on Mars, humans need the same
things they need on Earth, including water, a
breathable atmosphere and food. Mars is a
hostile planet, and as of early 2015, is unable
to support human life.
 Scientists have thought of creating an air-
tight habitat that would allow settlers of the
planet to grow their own food and to live in a
breathable environment
 A water recycling program must be
implemented, as would some type of
radiation protection.

19. HUMANS NEED TO BE A MULTIPLANET SPECIES-
ELON MUSK
The only home humans have ever known is Earth. But history
shows that surviving as a species on this tiny blue dot in the
vacuum of space is tough and by no means guaranteed.
The dinosaurs are a classic example: They roamed the
planet for 165 million years, but the only trace of them
today are their fossilized remains. A colossal asteroid wiped
them out. So it can wiped us out too.
Putting humans on more than one planet would better ensure our
existence thousands if not millions of years from now.
