Our ability to accurately forecast the coupled ionosphere - thermosphere system is strongly enhanced by the availability of continuous datasets of multi-point in-situ measurements of key parameters. In the current era, missions such as C-NOFS are providing extremely high-quality data on selected orbits, but there is a complementary requirement for mass coverage of the low Earth orbit system with low-cost, low-impact workhorse detectors that can fly on any (and every) spacecraft with minimal integration costs. Such a mass-mapping will yield a rich calibration datamass for nowcast and forecast models that can be compared in utility to the current tropospheric weather datasets used for terrestrial weather forecasting. The US Air Force Academy has been developing a series of such detectors that measure ion and electron energy (with dE/E of ~7% or better), density, and scale feature size down to ~km, and can calculate temperatures to better than 1 eV. Each instrument is <1000cm3, <1 kg, <1W. Instruments have been integrated onto spacecraft from 50kg micro-satellites to the International Space Station. We discuss the design heritage of these instruments from 2004 to future missions, and present results from instruments currently in orbit.
