Transcript of Mars

MARS THE RED PLANET Mars is 227,900,000 km away from the sun. The surface of Mars has craters like the moon, and volcanoes, valleys, deserts, and polar ice caps like Earth. Mars has the largest volcano in the solar system. OLYMPUS MONS Olympus Mons is 24 km high. Mount Everest is 8.8 km high. You could stack 3 Mount Everests to get the height of Olympus Mons! Mars is the planet that has seasons most
like Earth. But don't get any crazy
ideas about living there because it
is much colder than Earth! The
average temperature in the mid
latitude range is approximately
-50° Celsius!!! The gravity on Mars is 38% of the
gravity on Earth. So if you weighed
100 pounds on Earth, you would weigh
38 pounds on Mars! EXPLORATION OF MARS So far we've only been able to explore with machines. No human has been to Mars yet. Most attempts to explore Mars have been unsuccessful, especially during the earlier years. Some recent successful missions include: (Jan 2004) Twin Mars Exploration Rovers named Spirit and Opportunity land on surface of Mars. This mission proved that liquid water used to exist here. (March 2006) NASA Mars Reconnaissance Orbitar (MRO) arrived in Mars' orbit and began recording Martian landscape. (Aug 2012) The Curiosity Rover landed on Mars. This Rover is bigger and more advanced than Spirit and Opportunity. Curiosity can tell the chemical make up of rocks from 7 meter distances. The Opportunity Rover just recently set a NASA record! It has traveled 22.22 miles on Mars. The previous NASA record was 22.21 miles traveled by the Apollo 17 Rover in 1972 on the moon. Mars has two moons. Phobos Mars' moons are more like asteroids than Earth's moon because of their shape and what they're made of. While both moons are some of the smallest in the solar system, Phobos is the bigger one and it is only 22.2 km across. Phobos orbits Mars 3 times a day! It takes our moon 27 days to orbit once!!! Phobos is also the closest orbiting moon in the solar system. It is only 6,000 km from Mars. Our moon is 384,400 km from Earth! Deimos Deimos is Mars' smallest moon. It is only 12.6 km across. Deimos orbits Mars once every 30 hours and is about 20,000 km away. Phobos is slowly moving towards Mars. In the next 50 million years Phobos will crash into Mars or turn into a ring of rocks around it! It has a thin atmosphere composed
mostly of carbon dioxide. A Martian day is 24 hours and 40 minutes, almost the same as Earth's! A Martian year is 687 Earth days. This Martian Meteorite was found in Antarctica on August 6, 1996. Scientists believe they've found fossils of bacteria in it which means there may have been life on Mars at some point. On the other hand, Deimos is drifting away from Mars! Eventually Mars might not have any moons! Music By: Like Earth, Mercury, and Venus, Mars is a terrestrial planet. A terrestrial planet is made of mostly rocks and metals. Iron oxide gives Mars its reddish appearance. Mars is the fourth planet from the sun and the second smallest in our solar system. Ancient Egyptians were the first to observe Mars. Martian microbes NASA scientists have discovered that our moon
is really the Death Star. Mars Colony
