Frank Bethune McDonald (May 28, 1925 – August 31, 2012) was anAmericanastrophysicist who helped design scientific instruments for research flights into space. He was a key force behind several initiatives and programs of theNational Aeronautics and Space Administration, for which he served aschief scientist.[1]
During his career, he was project scientist on nine NASA missions and principal investigator on 15 space experiments. He wrote more than 300 scientific publications. In 1986, he was elected to theNational Academy of Sciences.
McDonald was born inColumbus, Georgia to Frank B. McDonald and Lucy Kyle McDonald.[2] After he graduated from Duke University in 1948, he attended theUniversity of Minnesota where he obtained a master's degree in 1951. Here, under the supervision ofEdward P. Ney, he completed a doctorate in physics in 1955. For his thesis, he carried out balloon flights to the top of the atmosphere of acloud chamber triggered by ascintillation counter to study the charge distribution of primarycosmic rays.
In 1956, McDonald began his career at theUniversity of Iowa. In collaboration withJames A. Van Allen he worked on "rockoons", which were small rockets lifted to 70,000 feet by balloons. At this height, the rockets would ignite and shoot up to 350,000 feet, carrying equipment intended to study cosmic rays and particles trapped in Earth's magnetic field. The same year, McDonald combined the scintillation counter of his thesis with acherenkov detector into a balloon instrument that not only provided a novel measurement of the energy spectrum of primary cosmic ray helium nuclei, but also served as a prototype for devices carried on many spacecraft.[3]
In 1959, McDonald became one of the first scientists to joinNASA's newGoddard Space Flight Center inGreenbelt, Maryland.[4] For the next 11 years, he carried out cosmic ray research here as head of the Energetic Particles Branch. During that time, he provided the conceptual framework for a series of small spacecraft known as the international monitoring platforms, or IMP.
From 1970 to 1982, McDonald was chief of Goddard's Laboratory of High Energy Astrophysics, where he helped design a satellite program with instruments that could study X-rays, gamma rays and cosmic rays. He also led experiments flown on space probes that have gone beyond theSolar System. In particular, onPioneer 10,Pioneer 11,Voyager 1[5] andVoyager 2,[6] he helped design, build and use instruments to measure cosmic rays.[7]
From 1982 to 1987, asNASA Chief Scientist, McDonald was a principal adviser to theNASA administrator and other senior officials. In that role, he helped start a NASA partnership with historically black colleges to fund research projects by faculty members and graduate students.
He also played an active role launching NASA'sTeacher in Space Project to connect schoolchildren with science and space exploration.Christa McAuliffe, the first teacher in space, died in theSpace ShuttleChallenger disaster in 1986.
In 1987, McDonald returned to Goddard, where he became associate director and chief scientist.
After McDonald retired from NASA in 1989, he joined the Institute for Physical Science and Technology at theUniversity of Maryland, where he was a senior research scientist until his death.[8]
