Material that is ejected from comets reflects light, giving them their characteristic dust tails. This material is spread throughout the solar system and makes up the interplanetary dust enviroment. When planets move through this environment, some of this dust falls into the upper atmosphere, which results in shooting stars. When a planet passes through the orbit of a comet, that planet experiences a meteor shower. The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission's primary remote sensing instrument, the Imaging Ultraviolet Spectragraph (IUVS) makes altitude profiles of the Martian atmosphere to characterize neutral and ion species. I use this instrument to study the persitant meteoric layer found at Mars.
