"Of the 39 attempts to study Mars up close at least 16
have been partially successful. We have learned enough
to actually begin planning to live on Mars with real
success.

Mars atmosphere is composed chiefly of carbon dioxide
(95.3 percent), nitrogen (2.7 percent) and argon (1.6
percent), with traces of oxygen, carbon monoxide and
water vapor. Surface atmospheric pressure on Mars is
less than 1/100th that of Earth's average atmospheric
pressure; its surface temperature averages -53 C (-64 F),
varying from -128 C (-199 F) during polar night to 27 C
(80 F) during midday near the equator when Mars is at
its closest point in orbit around the Sun.

I would like to discuss real plans and accomplishments of settling a colony on Mars in our lifetime. If you have any thoughts on the subject please discuss them."
