Mary Hudson (born January 6, 1949} is the Eleanor and Kelvin Smith Distinguished Professor of Physics at Dartmouth College.
[2] From 2010 until 2016, she retained an affiliate position at the National Center for Atmospheric Research in the High Altitude Observatory.
[4] Starting with her Ph.D. research, Hudson worked on the spread F problem,[5][6] a phenomenon known to impact the transmission of signals by satellites.
[4] During her time at the University of California Berkeley, Hudson worked on the team led by Forrest Mozer that made the first electric field measurements in the ionosphere using the S3-3 satellite;[7][8] the electrostatic shocks they measured accelerate electrons to make the auroras that can be seen at night in high latitudes.
[2] Her research on this project centered on magnetosphere physics, especially the trapping of solar energetic particles,[13][14] which has consequences for technology used on Earth.
