Science

Ian.Johnson.PhotoSatellite designs have become increasingly smaller, lighter, and cheaper; but with smaller satellites comes the need for smaller rockets to propel them. Enter the Pulsed Plasma Thruster, a rocket small enough to move microsatellites while in orbit and extend the lifetime of their missions. Ian Johnson, a graduate student in UW’s Department of Aeronautics and Astronautics, will share the research and mechanics behind these palm-sized rockets and their immense power.

hutchinsLightning isn’t frequently found in Seattle, but it is in other parts of the world. Michael Hutchins, PhD candidate in the Earth and Space Sciences Department, has been tracking it for years to find out the who, what, where, and why of lightning. By placing radio antenna in more than 30 countries, he’s been able to track lightning and thunderstorms around the world, knowing where and when it occurs. Hutchins says the research could have real implications for flight safety, lightning predictions, and its relationship to Hurricanes and other disasters.
