AB: Results from recent in-situ measurements of thermospheric density are presented. The measurements were made by an ionization-gauge based pressure sensor hosted on a space vehicle orbiting in the lower thermosphere. Approximately nine months of nearly continuous operation have produced new insights into the structure of the thermosphere and small scale perturbations, including waves and other disturbances. These insights are presented and compared to those gained from earlier work. The new measurements are also used to highlight the need for new experiments and suggest the measurements that new experiments should make
