Donald Gurnett
Donald Alfred Gurnett (April 11, 1940 – January 13, 2022) was an American physicist and professor at the University of Iowa who specialized in plasma physics. Early life and education Gurnett grew up in Fairfax, Iowa. In his spare time he built and flew model airplanes with a club at the airport in Cedar Rapids. There he met the German expatriate scientist Alexander Lippisch. Gurnett received his bachelor's degree in electrical engineering from the University of Iowa in 1962, and then his master's degree in physics in 1963 and his doctorate in 1965. Career Gurnett's research into space plasmas (and his involvement in the development of electronics and measuring devices for space missions) began while he was a student and eventually led to early studies of plasma waves in the Earth's radiation belt (via low-frequency radio waves). From 1962, he was a NASA trainee at the University of Iowa and Stanford University (1964/65). He participated to the Injun satellites program desi ...

Cassini–Huygens
''Cassini–Huygens'' ( ), commonly called ''Cassini'', was a space research, space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its Rings of Saturn, rings and Moons of Saturn, natural satellites. The Large Strategic Science Missions, Flagship-class robotic spacecraft comprised both NASA's ''Cassini'' space probe and ESA's Huygens (spacecraft), ''Huygens'' lander (spacecraft), lander, which landed on Saturn's largest moon, Titan (moon), Titan. ''Cassini'' was the fourth space probe to visit Saturn and the first to enter its orbit, where it stayed from 2004 to 2017.

University Of Iowa Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...
