Marcia Neugebauer (born September 27, 1932) is a prominent American geophysicist who made contributions to space physics.
Neugebauer's research are among the first that yielded the first direct measurements of the solar wind and shed light on its physics and interaction with comets.
Neugebauer was an investigator of the Mariner 2 plasma analyzer that made the first extensive measurements of the solar wind and discovery of its properties.
She also developed analytical instruments that orbited Earth, some set up on the moon by the Apollo astronauts, and others that flew by Halley's comet on the European Giotto mission.
Neugebauer was Study Scientist for many space missions during her long career with NASA, and held several management positions at the Jet Propulsion Laboratory, including Manager of the Physics and Space Physics sections, Manager of the Mariner Mark II study team, and Project Scientist for Rangers 1 and 2 and the Comet Rendezvous Asteroid Flyby mission.
Neugebauer served as president of the American Geophysical Union from 1994-1996 and was Editor-in-Chief of its journal Reviews of Geophysics.
She also chaired the National Academy of Sciences' Committee on Solar and Space Physics.
Neugebauer was born in New York City.
She received a B.A.
in physics from Cornell University in 1954, followed by an M.S.
in physics from the University of Illinois in Urbana in 1956.
She was awarded an honorary Doctorate of Physics in 1998 by the University of New Hampshire.
She was married to astrophysicist Gerry Neugebauer.
