In this story from the College of Liberal Arts and Sciences, Arissa Khan tells about her work as an undergraduate student researcher on the Observing Cusp High-altitude Reconnection and Electrodynamics (OCHRE) Mission.

University of Iowa physicists have detailed interactions between magnetic field lines of the sun and Mars that may help explain how Mars turned from a warm, hospitable planet into a dry, cold, and hostile environment. Using orbital observations and evidence obtained from NASA rovers on the red planet’s surface, scientists know that billions of years ago Mars was much wetter and warmer, with a thicker atmosphere.

Join us April 23 at 5 pm CDT for this virtual webinar about TRACERS, a cutting-edge NASA satellite mission led by the University of Iowa. TRACERS will study the magnetic interactions between the sun and Earth, helping to unlock the mysteries of space weather.
