UI researcher to lecture April 2 on Earth-space dynamics
Crockett Grabbe, research scientist in the University of Iowa College of Liberal
Arts and Sciences' department of physics and astronomy, will lecture on "The
Emerging Dynamic SuperGlobe" at 7 p.m. Tuesday, April 2 in Lecture Room
1 of Van Allen Hall.
Grabbe's talk, free and open to the public, will include colorful photographs
of the Earth's spatial environment, as viewed from both the ground and from
spacecraft. He plans to discuss how conditions near the Earth are dynamically
linked to the sun, and how humanity's growing dependence on space is creating
a "SuperGlobe." Grabbe will discuss the recent development of space
weather as a science and 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.
