Dr. James Van Allen has died
Renowned space scientist Dr. James A. Van Allen died this morning at the age of 91. Although he had a lifetime’s worth of contributions to astronomy, space science and space exploration, Dr. Allen was best known for his discovery of the radiation belts that surround the Earth. An experiment he designed for the spacecraft Explorer 1 gauged the Van Allen belts using tiny Geiger counters to measure radiation. He retired from full time teaching at the University of Iowa in 1985, but continued to write, oversee research, and monitor data sent back by spacecraft he was involved with.
