What we would need to survive on an other plant

1. What we would need to survive on an other plant By Thalia Watson http://www.cosmosmagazine.com/news/2276/buzz-aldrin-mars-pioneers-should-stay-there-good

2. Our task • What do you think would be required to make it possible for humans to survive on other planets? Make sure you describe the environmental conditions on at least two different planets.

3. Planet Mars

4. Mar’s surface Mars is a terrestrial planet. It has a hard rocky surface that you could walk on. Mars' surface is dry and much of it is covered with a reddish dust and rocks. Mars has two permanent polar ice caps.

5. Mar’s atmosphere The Martian atmosphere consists of carbon dioxide (95 percent), nitrogen (2.7 percent), argon (1.6 percent), oxygen (0.2 percent) and trace amounts of water vapour and carbon monoxide

6. Mar’s gravity The surface gravity on Mars is only about 38% of the surface gravity on Earth. If you weigh 100 pounds on Earth then you would weigh only 38 pounds on Mars. http://scienceandtechnology.jpl.nasa.gov/research/ResearchTopics/topicdetails/?ID=48

7. Mar’s Moons Mars has two moons and their names are Deimos and Phobos. http://en.wikipedia.org/wiki/Deimos_(moon) http://en.wikipedia.org/wiki/Phobos_(moon)

8. Mar’s temperature Mar’s surface temperature can usually range from about -120 degrease Celsius and to about -30 degrease Celsius. http://nineplanets.org/mars.html

9. Planet Saturn http://www.trinity.wa.edu.au/intranet/subjects/astronomy/My%20Webs/Yr%208%20Astro/SATURN%20CLOSEUP.htm

10. Saturn surface Saturn has a ring system that is divided into nine continuous and three discontinuous main rings (arcs), consisting mostly of ice particles with a smaller amount of rocky debris and dust. Sixty-two[19] known moons orbit the planet; fifty-three are officially named. This does not include the hundreds of "moonlets" within the rings. Titan, Saturn's largest and the Solar System's second largest moon (after Jupiter's Ganymede), is larger than the planet Mercury and is the only moon in the Solar System to possess a significant atmosphere http://digitaljournal.com/article/301373

11. Saturn atmosphere Saturn is approximately 75% hydrogen and 25% helium with traces of other substances like methane and water ice.Saturn's atmosphere, although similar to Jupiter's, is much less interesting to look at from a distance. But enhanced-colour images (shown above) allow us to study the bands across which run parallel to the equator much like Jupiter's, indicating violent winds. http://www.esa.int/esaMI/Cassini-Huygens/SEMPQ6HHZTD_0.html

12. Saturn gravity '''About 74% of the surface gravity on Earth. For instance, if you weighed 100 lbs. on Earth, you weigh 74 lbs. on Saturn.Read more: http://wiki.answers.com/Q/How_strong_is_Saturn's_gravity#ixzz1eF9om4W2

13. Saturn Tempters The temperatures below Saturn's clouds are much higher than those at the top of the clouds. The planet gives off about 2 1/2 times as much heat as it receives from the Sun. Many astronomers believe that much of Saturn's internal heat comes from energy generated by the slow sinking of helium through the liquid hydrogen in the planet's interior. The temperature at the top of Saturn's clouds averages -285° F (-175 °C). The core of Saturn is much hotter, estimated at around 11,700 °C.Read more: http://wiki.answers.com/Q/What_is_the_temperature_of_Saturn#ixzz1eF8oP9fx
