&lt;br /&gt;
It is cold on [[Mars]].&lt;br /&gt;
&lt;br /&gt;
== Biological requirements ==&lt;br /&gt;
&lt;br /&gt;
Terran biology prefers temperatures at which water is liquid.&lt;br /&gt;
&lt;br /&gt;
=== Human requirements ===&lt;br /&gt;
&lt;br /&gt;
At 0° F flesh freezes in minutes.  At -50° F flesh freezes in seconds.  &lt;br /&gt;
&lt;br /&gt;
=== Plant requirements ===&lt;br /&gt;
&lt;br /&gt;
[[Psychrophile]]s can grow in temperatures as low as 32° F.&lt;br /&gt;
&lt;br /&gt;
== Engineering requirements ==&lt;br /&gt;
&lt;br /&gt;
The simplest means of meeting these temperature conditions is to maintain them within an environmentally controlled structure.  Inhabited structures must be heated.  Good insulation helps conserve energy.&lt;br /&gt;
&lt;br /&gt;
