Commander David Scott’s Apollo 15 spacesuit was a marvel of technology that allowed him to perform three long EVAs across the lunar surface. It is made even more fascinating by the Moon dust that covers it. Join planetary scientist Gareth Morgan as he discusses the origin of the dust, the geological setting in which Commander Scott picked it up, and the problems it poses for human missions.
