A meteor the size of a dust grain is too small to have any kind of life as we know it. There have been some larger meteorites that have contained chemicals similar to what life has, although this does not mean that they have actually had life on them.

In space there is no atmosphere to stop meteors, but they are so tiny that they pose no threat of damage. Spacecraft are hit by them all the time. A larger meteor—about an inch across—could possibly ... .html Click here

... that can stop them from penetrating the module skin. The skin is also equipped with a multi-layer insulation blanket that protects the modules from temperature extremes. Water has been shown to effectively block radiation, so we are proposing a system of water blankets on the inside wall of the modules.
