For atmospheric sensing, a race to the middle
In order to index climate, explore weather, or learn about the universe, scientist will need technology suited to the mesosphere—the middle of Earth’s five atmospheric layers, with the potential to withstand harsh conditions. Igor Bargatin, associate professor in the Department of Mechanical Engineering and Applied Mechanics is solving the mesosphere’s air problem by using light to levitate materials much larger than microscopic particles.
