There is a great need for in situ measurements of atmospheric ion and neutral composition and density due to a dearth of measurements since the DE satellite mission ~30 years ago. The Ion and Neutral Mass Spectrometer (INMS) seeks to fill this void while achieving several measurement firsts and enabling new scientific studies, including constellation missions. INMS is a tiny, versatile time of flight spectrometer that measures atmospheric composition within a 1.1 U volume. INMS was recently deployed from the International Space Station as part of GSFC's Dellingr CubeSat mission. This presentation includes an introduction to the instrument technology and atmospheric composition data from Dellingr.
