Journey To Mars (Astronomy)

DEIMOS-orbits mars every 30 hrs-one of the smallest moons of solar systemBOTH MOONScan likely be used as a base for astronauts to observe Mars and launch robots to its surface

PHOBOS-has a 10 km wide crater-orbits 6000 km above Martian surface-orbits 3 times a day-will crash into Mars or form a ring around it in the next 50 million years






SURFACE CONDITIONS, TERRAIN• Rocky, terrestrial planet• Solid surface altered by volcanoes, impacts, crustal movements, & dust storms• Iron minerals in soil oxidize (rust), causing the soil and dusty atmosphere to have a red appearance.CLIMATEThe minimum to maximum temperatures of Mars is -153 to 20 degrees Celsius.Mars has Earth-like seasons, but they are twice as long. Seasons of the Southern Hemisphere are more extreme. Also, dust storms can cause increase in temperature.

ATMOSPHEREMars's dusty atmosphere is made mostly of Carbon Dioxide, Nitrogen, Argon, Oxygen, and methane. The atmosphere is too thin for liquid water to last long on the surface. The atmospherebeing so thin also causeswidely varying temperatures,as it cannot store muchsolar heat.

DISTANCE FROMEARTH TO MARSMars and Earth are closest every two years, at which point they are 56 million km apart. The furthest they are ever apart is 401 km. (see video)LOCATION OF MARSLocated in our solar system in the Milky Way galaxy, Mars is the fourth planet from sun. It orbits at about 228 million km from the sun, orbiting between Earth and Jupiter.

    This is Ray, I like how the Atmosphere was described and you also did a great job describing Phobos and Deimos. The video was great by the way. I did not know the moon looked like that. I learned a lot from looking at your glog, thanks
