UI researcher develops 'superglobe' video

Crockett Grabbe, research scientist in the University of Iowa College of Liberal Arts and Sciences' department of physics and astronomy, has developed a new, 30-minute educational video, "The Emerging Dynamic SuperGlobe," that examines Earth's spatial environment and the system of man-made satellites encircling it.

Grabbe's video, suitable for people of all ages, includes photographs of the northern lights, the southern lights and solar storms. It describes how conditions near the Earth are linked to the sun and tells how humanity's growing dependence on space is creating a "SuperGlobe." It also shows how space weather affects commercial space ventures, such as the deployment and operation of satellites that form part of the SuperGlobe.

Grabbe is a member of the National Speakers Association, the American Physical Society, the American Association of Physics Teachers, the American Geophysical Union, the International Union of Radio Science, and the American Association of Physicists in Medicine.
