Mars

Composition of the atmosphere

Mars

• carbon dioxide (CO²) : 95,32%

• Oxigen (O2) : 0,13%

• nitrogen (N) : 2,7%

Earth

• carbon dioxide (CO²):

0,038 %

• Oxigen (O2): 20,946 %

• nitrogen (N): 78,084 %

Air pressure

Mars: = 0,006 bar

Earth: = 1,013 bar

Due to the low atmospheric UV radiation is very high ()

temparature

on Mars

• Min.: 140 K (–133 °C)

• Middle.: 218 K (−55 °C)

• Max.: 300 K (+27 °C)

near the equator:

• at the day ca. 20 °C

• in the night ca. -85°C

Gravity

• Only 38 % of the terrestrial gravity

Marsyear:

687 days

( about 1.9 Earth years )

Martian day:24 hours and 37 minutes

Rotation axis:25 ° 12 ' on Mars

and 23 ° on earth.

methane emissions

The reason for this observation :

volcanic activity

Metorits

old reserves

microorganisms

Life on Mars?

1. I present you the mars. I have structured my presentation in three Parts:

The structure of the mars: Is there life on mars

And two Comets from mars, which were discovered on earth.

2. On the second page you can see the composition of the atmosphere between earth

and mars

3. On the third page I have talked about the air pressure on mars and earth

4. The forth page handled about the temperature on mars and earth from the min -

max.

5. At next foil you can see a picture of the temperatures on mars

6. The next picture shows the soil temperature of mars and earth.The soil on earth has

by 15m 10 C° and on mars is a 2 km deep permafrost

7. The seventh page shows the gravity on mars

8. The mars year, mars day and the rotation of mars are on the eight page.

9. On page 9 is a picture of the methane emissions on mars.

10. The reason for this observation:

Volcanic activities: That’s impossible because, there is no volcanic activity any more.

Meteorites: This is also impossible, because the meteorites doesn’t have so much

methane emission.

The only possible thing is that there are old reserves and microorganism.

11. Life on mars

12. Page 11-12 show the meteorite “Yamato 000593” his parts of mars and the

iddingsite of it.

13. Page 13 shows a picture about Nakhla
