Roald Sagdeyev is a Russian plama physicist who was also one of the leading figures in Soviet space science from the 1960s to the 1980s. Sagdeyev was involved in virtually every Soviet lunar and planetary probe in this period, including the highly successful Venera and Vega missions. He also advised Soviet leader Mikhail Gorbachev on space and arms control at the 1986 Geneva, 1987 Washington, and 1988 Moscow summits. In the late 1980s, Sagdeyev left the Soviet Union and settled in the United States where he headed the East-West Science and Technology Center at the University of Maryland, College Park.
