  1. 1. EXPLORING ON MARS - THE RED PLANET ARUNSENAPATHY R 11/6/2013 1
  2. 2. PRESENTATION OUTLINE  OBJECTIVES  MARS | AT A GLANCE  IMPACT CRATERS ON MARS  REASON FOR OCCURRENCE  BIGGEST CRATERS ON MARS  MARS MISSIONS  PLANETARY ROVING VEHICLES ON MARS | HISTORY & COMPARISON  CONCLUSION  REFERENCE 11/6/2013 2
  3. 3. OBJECTIVES  TO UNDERSTAND THE ESSENTIALS OF MARS  TO KNOW ABOUT IMPACT CRATERS ON MARS AND THE REASON FOR OCCURRENCE  TO DISCUSS ABOUT THE BIGGEST IMPACT CRATERS ON MARS  TO COGNIZE THE MODERN INNOVATIONS IN MARS 11/6/2013 3
  4. 4. MARS | AT A GLANCE 11/6/2013 4
  5. 5. MARS  FOURTH PLANET FROM THE SUN | SECOND SMALLEST PLANET IN THE SOLAR SYSTEM  NAMED AFTER THE ROMAN GOD OF WAR  DESCRIBED AS THE “RED PLANET”  THE IRON OXIDE PREVALENT ON ITS SURFACE GIVES IT A REDDISH APPEARANCE  11/6/2013 A TERRESTRIAL PLANET WITH A THIN ATMOSPHERE 5
  6. 6. MARS - THE RED PLANET  MARS SURFACE IS COMPRISED OF IRONRICH MINERALS (RUST OR OXIDIZE) AND DUST.  THE MARTIAN SURFACE IS NOT ALL RUST-COLORED, HOWEVER, BECAUSE DEPENDING ON THE OXIDATION PROCESS, THE MINERALS CAN BE A RANGE OF COLORS FROM BUTTERSCOTCH TO RUST. 11/6/2013 6
  7. 7. MARS LOCATION MARS 11/6/2013 7
  8. 8. MARS FACTS  DISTANCE FROM SUN ≈1.52 TIMES AS FAR AS EARTH  TIME TO ORBIT THE SUN ~ 26 EARTH MONTHS  ATMOSPHERE ~ MOSTLY CARBON DIOXIDE  MARTIAN DAY ~ 24.7 HOURS  TEMPERATURE ON THE PLANET’S SURFACE HARDLY RISES ABOVE FREEZING POINT 11/6/2013 8
  9. 9. EARTH AND MARS | COMPARISON PARTICULARS EARTH MARS RADIUS 6378 KM 3397 KM DENSITY 5515 KG/M3 3933 KG/M3 GRAVITY 9.8 M/S2 3.72 M/S2 YEAR 365.25 DAYS 686.98 DAYS ECCENTRICITY 0.017 0.094 DAY 24 HOURS 24 HR 39 MIN OBLIQUITY 23.45º 25.19º 11/6/2013 9
  10. 10. CONTD… THE LAND AREA OF EARTH IS APPROXIMATELY EQUAL TO THE TOTAL SURFACE OF MARS THE LAND AREA OF AFRICA IS ABOUT THE SAME AS THE TOTAL SURFACE OF THE MOON 11/6/2013 10
  11. 11. MARS | SURFACE FEATURES  SURFACE COLOR “RED”  FEATURES  IMPACT CRATERS  LARGEST VOLCANO IN THE SOLAR SYSTEM (OLYMPUS MONS)  LARGEST CANYON IN THE SOLAR SYSTEM (VALLES MARINERIS)  ANCIENT RIVER CHANNELS VALLES MARINERIS  LAVA ROCKS  DUST: REDDISH FROM VOLCANIC ROCK 11/6/2013 11
  12. 12. MARS | ATMOSPHERE  UNBREATHABLE  THIN  DUSTY, MAKES THE SKY PINKISH, LOTS OF DUST STORMS  SURFACE PRESSURE: 1/150TH OF EARTH’S (ONLY 5.6 MILLIBARS)  COMPOSITION: 95% CO2, 3% N, 1.5% AR, 0.1% O2, 0.03% H2O 11/6/2013 12
  13. 13. MOONS OF MARS PHOBOS  MARS HAS TWO TINY MOONS NAMED “DEIMOS” (PANIC) & “PHOBOS” (FEAR) Deimos  THE MOONS ARE IRREGULAR AND VERY SMALL IN SIZE  PHOBOS 27X22X18 KM  DEIMOS 15X12X10 KM  THE MOONS ARE PROBABLY ASTEROIDS CAPTURED BY MARS 11/6/2013 13
  14. 14. WATER ON MARS  WATER IS THE KEY TO LIFE AS WE KNOW IT  THE NORTH AND SOUTH POLES OF MARS ARE COVERED WITH THICK ICE OR FROST  SOME ASTRONOMERS ABOUT 100 YEARS AGO THOUGHT THERE WERE CANALS ON MARS DUG BY INTELLIGENT CIVILIZATION  SPACE PROBES TO DATE HAVE NOT FOUND ANY TRACES OF CANALS ON MARS 11/6/2013 14
  15. 15. IMPACT CRATERS ON MARS 11/6/2013 15
  16. 16.  IMPACT CRATER IN MARS IS A LARGE HOLE IN THE GROUND CAUSED BY A METEORITE SMASHING INTO THE SURFACE OF MARS  EVERY SOLID BODY IN THE SOLAR SYSTEM SUFFERS FROM THE EFFECTS OF IMPACT CRATERING  THE PROJECTILES THAT CAUSE IMPACT CRATERS, TRAVEL AT VERY HIGH SPEED AND FASTER 11/6/2013 16
  17. 17. 11/6/2013 17
  18. 18. TERMINOLOGIES  CENTRAL PEAK - A MOUNTAIN FORMED IN THE CENTRE OF LARGE IMPACT CRATERS. THESE DO NOT OCCUR IN SMALL IMPACT CRATERS  EJECTA - A SHEET OF MATERIAL (ROCKS, SOIL) SURROUNDING THE CRATER THAT WAS THROWN OUT DURING THE IMPACT EVENT  ERODE - THE PROCESS BY WHICH SOMETHING IS WORN AWAY OVER TIME  FLOOR - THE FLOOR OF AN IMPACT CRATER (USUALLY EITHER FLAT OR BOWLSHAPED), LYING BELOW THE SURROUNDING GROUND LEVEL  IMPACT CRATER - A HOLE IN THE GROUND (USUALLY CIRCULAR) CAUSED BY THE IMPACT OF A METEORITE ONTO THE SURFACE OF A SOLID BODY 11/6/2013 18
  19. 19. CONTD…  METEORITE - A LUMP OF ROCK OR ICE THAT HITS THE SURFACE OF A PLANETARY BODY  PROJECTILE - AN OBJECT THAT STRIKES A SURFACE TO PRODUCE AN IMPACT CRATER. THESE CAN INCLUDE DUST PARTICLES, PEBBLES, ROCKS, COMETS AND ASTEROIDS  RAISED RIM - THIS IS THE EDGE OF THE IMPACT CRATER AND IS COMPOSED OF ROCKS AND MATERIAL PILED UP ON TOP OF ONE ANOTHER  RAYS - BRIGHT LINES OF EJECTA COMING FROM AN IMPACT CRATER. THESE CAN EXTEND FOR VAST DISTANCES IN THE CASE OF LARGE IMPACTS  TERRACED WALLS - THESE ONLY OCCUR IN LARGE IMPACT CRATERS. AFTER THE CRATER FORMS, THE WALLS OF THE CRATER SLIP, CREATING HUGE LANDSLIDES INSIDE THE CRATER 11/6/2013 19
  20. 20. REASON FOR OCCURRENCE OF IMPACT CRATERS ON MARS 11/6/2013 20
  21. 21.  FORMED BY A LARGE OBJECT SUCH AS AN ASTEROID OR A COMET  WHEN THESE LARGE OBJECTS HIT THE SURFACE THEY FORM HOLES (CRATERS)  LATE HEAVY BOMBARDMENT PERIOD OF OUR SOLAR SYSTEM  NO ATMOSPHERE TO PROTECT IT FROM ASTEROIDS  THAT'S WHY MARS HAS CRATERS 11/6/2013 21
