Qué tipo de vida puede encontrarse en Marte?

Your Question Has Been Answered
The question you submitted to the Phoenix Mars Mission ask the team has been answered.
Your question was: What kind of life can be found in Mars?
The answer to your question is: Life as we know it requires liquid water, but not necessarily its continuous presence. Phoenix will investigate a hypothesis that some ice in the soil of the landing site may become unfrozen and biologically available at times during warmer parts of long-period climate cycles. Life might persist in some type of dormant microbial form for millions of years between thaws, if other conditions were right. The spacecraft is neither equipped nor intended to detect past or present life. However, in addition to studying the status and history of water at the site, Phoenix will look for other conditions favorable to life. One condition considered essential for life as we know it is the presence of molecules that include carbon and hydrogen. These are known as organic compounds, whether they come from biological sources or not. They can be produced without life, but they include the chemical building blocks of life as well as substances that can serve as an energy source, or food, for life. Phoenix would be able to detect small amounts and identify them.
