Mars
- 1. The Inner PlanetsPart 3 Mars (5th grade) March 2017
- 2. The inner planetsinclude Mercury, Venus, Earth, and Mars. Mars’s axis tilt is similar to Earth’s.
- 3. Mars is the4th planet from the sun...
- 4. ...and the lastof the terrestrial planets.
- 5. Photo of Mars’ssurface taken by Pathfinder rover in 1997.
- 7. Mars has lessmass than Earth, so it has less gravity, too. If you weigh 100 lbs. on Earth, you would only weigh about 38 lbs. on Mars.
- 8. https://youtu.be/z8aBZZnv6y8 Watch this 2:41video on the planets’ orbits around the sun. Keep in mind that the scale is not accurate. The real scale is so large, it would be difficult to see each planet. Pay attention to Earth and Mars. Which orbits the Sun the fastest?
- 9. Question: Which orbitsthe Sun faster...Earth or Mars?
- 10. It takes Marsabout 2 Earth years to orbit the Sun.
- 11. A Martian dayis close to an Earth day. It is 24 hours 39 minutes long. A sunset on Mars.
- 12. How Did MarsGet Its Name? It’s red, as though from blood shed in battle. So, the Romans named it for their god of war, Mars. The Greeks called him “Ares”. It was known to the Babylonians 3,600 years ago as the “Star that Wandered”. Mars
- 13. Mars’s nickname is“The Red Planet”.
- 14. Mars is redbecause the dust on Mars is composed mostly of rusted iron. Oxygen chemically reacts with iron, creating rust.
- 15. The Martian skyis reddish in color because of its dusty atmosphere...
- 16. Light is madeof a spectrum of colored wavelengths. You can see this spectrum when you look at a rainbow...
- 17. The rust dustthat’s in the Martian atmosphere absorbs the blue light and scatters the red light, giving the sky a rusty color.
- 18. Interestingly, while sunsetson Earth are red, sunsets on Mars are blue. Earth sunset Mars sunset
- 19. What is theatmosphere on Mars like?
- 20. Mars has athin atmosphere. It is only 1% as thick as Earth’s. Mars Earth
- 21. Mars’s atmosphere is composedmostly of carbon dioxide.
- 22. There is norain on Mars because the low temperatures and pressures mean water can only exist as vapor or ice, although it may have have rained in the geologic past say scientists. This photo shows water ice that formed in a trench where a rover had scooped out a soil sample.
- 23. Mars has alot of dust storms. Watch the following 3:24 min. video about Martian dust storms. https://youtu.be/SA1_bzS8-AI
- 24. Are there anyclouds on Mars now?
- 25. Clouds on Marsare sometimes localized and can sometimes cover entire regions, but have not yet been observed to cover the entire planet. ... The clouds consist of water ice condensed on reddish dust particles suspended in the atmosphere.
- 26. NASA researchers havedetermined that Mars’s once rich atmosphere was stripped away by solar winds in the early days of the Solar System, causing the planet to dry out.
- 27. This shows howEarth’s magnetic field protects our own planet from solar wind. Without a magnetic field, solar wind would cause our atmosphere’s gas atoms to be blasted into space.
- 28. The liquid ironin our planet’s outer core is constantly flowing and moving. This movement generates an electric current, creating our planet’s magnetic fields. outer core
- 29. Mars lost itspowerful magnetic field when it cooled too quickly, stopping it from having molten iron in its core. Now, the magnetic field Mars has left is simple and small.
- 30. NASA researchers believethat around 4.3 billion years ago, Mars had incredibly deep oceans that held more water than the Arctic Ocean here on Earth. Mars’s ocean may have looked like this.
- 31. Is Mars hotor cold?
- 32. Mars is acold planet. Because its atmosphere is so thin, it doesn’t have a "thermal blanket” to retain any heat energy.
- 33. In winter, nearthe poles temperatures can get down to minus 195 degrees F. Notice Mars’s polar ice caps.
- 34. Mercury and Venusdon’t have any moons. Does Mars?
- 35. Mars has 2moons!
- 36. They were mostlikely meteors that were captured by Mars’s gravity.
- 37. This illustrates Phobos’sand Deimos’s orbits around Mars.
- 38. Both moons aresmall.
- 39. The moons werediscovered by Asaph Hall in 1877. He named them after the mythological sons of Mars.
- 40. Phobos means “fear”or “panic”. Phobos has a 6 mile wide crater. Phobos whips around Mars 3 times a day.
- 41. Phobos is graduallyspiraling inward, drawing about 1.8 m closer to the planet each century. Within 50 million years, it will either crash into Mars or break up and form a ring around the planet.
- 42. Deimos means flight(as in running away after an overwhelming defeat). Deimos orbits Mars once every 30 Earth hours.
- 43. Mars has thelargest volcano in the solar system. It is called “Olympus Mons”.
- 44.
- 45. The tallest mountainson Mars, Earth, and Venus compared. Mars Venus Earth
- 46. Mars also hasthe largest canyon in the Solar System. The canyon was named “Valles Marineris”. It is up to 4 miles deep and is 2,500 miles long! It is 125 miles wide at its widest point.
- 47. This shows theMars canyon compared to the size of the United States. Watch the 3:44 min. video on this canyon. https://youtu.be/crsqzZNUXsY
- 48. How many cratersdoes Mars have?
- 49. Mars has morethan 635,000 impact craters that are each at least a ½ mile wide. In this image, each red dot represents one such crater.
- 54. There have beenmany missions to Mars and we Earthlings will continue to explore Mars now and in the future. Click on the link below to view the missions to Mars. The link may need to be cut and pasted into the browser. https://en.wikipedia.org/wiki/List_of_missions_to_Mars
