Career
From Johns Hopkins University in 1968 in Atmospheric Sciences. He was Principal Investigator for the White Light Coronagraph operated by the High Altitude Observatory (HAO) aboard the manned Skylab satellite from 1970-1977. MacQueen was Head of the Coronal Physics Section in HAO from 1977-1979, and was responsible for analyzing coronal photographs made during the Apollo 15, 16, and 17 lunar landing missions as Principal Investigator (1971–1973).
He later served as principal investigator for several research projects, including HAO’s Coronagraph/Polarimeter Experiment that was launched aboard National Aeronautics and Space Administration’s Solar Maximum Mission spacecraft (1975–1979.
1984–1986), the Rocket Coronagraph Experiment (1975–1979), and the Coronagraph/X Ray/XUV experiment as part of the Solar Polar Mission (1978-1983).In a joint project with the Harvard/Smithsonian Center for Astrophysics, he was one of the principal investigators for a series of solar observing rocket flights. From 1979 to 1986 Doctor MacQueen was Director of HAO. He then became Associate Director of NCAR from 1986–1988, and Acting Director of NCAR from 1988–1989.
While at HAO and NCAR, Doctor MacQueen published several articles on coronal streamers and transients. Doctor MacQueen was also a lecturer (1969–1979) and an adjunct professor in the Department of Astrophysical, Planetary and Atmospheric Sciences at the University of Colorado.
He left NCAR in 1990 after a one year sabbatical to head the Physics Department at Rhodes College, where he taught until 2001.
