Make Mars Great Again - Issue 43: Heroes

Mars is currently inhabited by an estimated 1 million microbes. They coat the surfaces and crowd the innards of our robotic landers and rovers, which international policy requires to be cleaned, but not fully sterilized. The bugs are dormant, but viable. If Mars warmed up and water began to flow again, these microorganisms would revive and reproduce. And it is within our power to make that happen.
