Space Colony on Mars
Transcript of Space Colony on Mars
Lack of Oxygen and its harsh climates. Other Domes are used to contain plants and trees for oxygen and food. The Martian atmosphere consists mainly of carbon
dioxide. Because of this, even with the reduced atmospheric
pressure, The partial pressure of CO2 at the surface of
Mars is some 52 times higher than on Earth. It also has
significant levels of carbon monoxide. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. In 2005, radar data revealed the presence of large quantities of water ice at the poles, and at mid-latitudes. The Mars rover Spirit sampled chemical compounds containing water molecules in March 2007. The Phoenix lander directly sampled water ice in shallow Martian soil on July 31, 2008. Mars lost its magnetosphere 4 billion years ago, so the solar wind interacts directly with the Martian ionosphere, lowering the atmospheric density by stripping away atoms from the outer layer. Both Mars Global Surveyor and Mars Express have detected these ionised atmospheric particles trailing off into space behind Mars. Compared to Earth, the atmosphere of Mars is quite rarefied.
