Space Physics

How can we more accurately forecast the space environment in the 21st century? A donut of radiation surrounds Earth, and poses a danger to astronauts and satellites. We need to improve models for forecasting the space environment of the future and its impacts on our technological society. Insights from Earth could also provide a better understanding of energetic particle dynamics at other magnetized planets in the solar system, as well as exoplanets throughout the universe.

How is the behavior of the Earth’s ionosphere controlled by both internal forces and external interactions? The ionosphere lies between the air we breathe and outer space, and is part of a complex system that changes on scales from meters to the planetary radius, and from seconds to decades. A better understanding of its behavior is critical since the ionosphere influences radio communication, navigation and surveillance. (JGR: Space Physics) 


How can we get a better understanding of geospace, the area between the Earth and Sun? It may be possible using an imaging radar made by combining a large, low-band VHF transmitter with one or more low-frequency radio arrays. Such an instrument would have great potential for discovery research as well as space weather applications. (Radio Science)
