Dr. Mihaly Horanyi and his colleagues at the University of Colorado are on the brink of watching an instrument they developed crash into the moon. It’s okay—it’s designed to. In the meantime, the instrument, LDEX, is measuring impacts from dust particles a fraction of the width of a human hair on NASA’s LADEE mission. It’s measured more than 11,000 of these tiny impacts since falling into orbit in October.
