Moon dust in your hair

NASA is funding a four-year study at the Colorado School of Mines on extra-terrestrial dust control. The surface of the moon is covered with a fine, talcum-like powder, the kind of stuff that kicks up really easily. Since the gravity on the moon is only one-sixth of Earth, humans and machines that disturb the moon ground will make lots and lots of dust. Stuck to spacesuits and boots, the dust is easily tracked into a lunar lander, where it gets quite annoying, gumming up equipment and covering instrument displays. The particles of moon dust can be harmful to lungs if inhaled over a long period of time. This is a major concern for long-term moon expeditions of the future. The dust problem will also be a major concern for astronauts sent to Mars, perhaps much worse. Mars dust contains the highly reactive compound iron-oxide, which, in essence, burns skin and can severly irritate lung tissue. The dust will be driven by the harsh wind storms that occur on Mars' surface. Link.
