Mars is a planet. It is the fourth planet
from the sun. Mars is known as the Red Planet. It gets its
red color from the iron in its soil. Mars has two small moons.
Permanent
settlement allows Mars One to use technology that is not substantially
different from existing systems. The hardware specifically needed for this
mission still needs to be designed, built, and tested extensively but the
technology already exists. Mars One is not an aerospace company will not
design or manufacture mission hardware. All equipment will be developed by
third party suppliers and integrated in their established facilities.
Why we need to live on Mars?
The reduced gravity well of Mars and its
position in the Solar System may facilitate Mars–Earth trade and may
provide an economic rationale for continued settlement of the planet. Given its
size and resources, this might eventually be a place to grow food and produce
equipment to mine the asteroid belt.
Related Similarity to Earth:
Earth is similar to Venus in bulk
composition, size and surface gravity, but Mars' similarities to Earth are more
compelling when considering colonization. These include:
- The
Martian day (or sol) is very close in duration to Earth's.
A solar day. on Mars is 24 hours, 39 minutes and
35.244 seconds.
- Mars
has a surface area that is 28.4% of Earth's, which is only slightly less
than the amount of dry land on Earth (which is 29.2% of Earth's surface).
Mars has half the radius of Earth and only one-tenth the mass. This means
that it has a smaller volume (~15%) and lower average density than Earth.
- Mars
has an axial tilt of 25.19°, similar to Earth's
23.44°. As a result, Mars has seasons much
like Earth, though on average they last nearly twice as long because the
Martian year is about 1.88 Earth years.
Difference from Earth
There are some extremophile organisms that survive in hostile conditions on Earth, including simulations that approximate Mars, plants and animals generally cannot survive the ambient conditions present on the surface of Mars.Surface gravity of Mars is 38% that of Earth. Although microgravity is known to cause health problems such as muscle loss and bone demineralization, it is not known if Martian gravity would have a similar effect. The Mars Gravity Biosatellite was a proposed project designed to learn more about what effect Mars' lower surface gravity would have on humans, but it was cancelled due to a lack of funding.
Mars climate is much colder than Earth, with mean surface temperatures between 186 and 268 K (−87 and −5 °C; −125 and 23 °F) (depending on the season and latitude). The lowest temperature ever recorded on Earth was 180 K (−89.2 °C, −128.6 °F) in Antarctica.
