Camella Nasr, Ionospheric Scientist   Image furnished by NASA The monitoring and understanding of Earth’s ionosphere—a critical region for communication, navigation systems and space weather—rely on innovative data sources and methods. NASA's Commercial Smallsat Data Acquisition (CSDA) program was created to tap into the growing commercial satellite industry. Orion Space Solutions serves as one of NASA's expert evaluators, helping determine if commercially available satellite data meets...

Camella Nasr, Research Scientist Scientists are always looking for better ways to model the ionosphere, the upper layer of Earth’s atmosphere that affects radio signals. One promising but underutilized tool is the Oblique Ionogram (OI) , which measures how long high-frequency (HF) radio waves take to travel between a transmitter and a receiver that are far apart. Unlike Vertical Ionograms (VIs) —which measure signals traveling straight up and down—OIs are more complex because HF waves take...
