Margaret Galland Kivelson (born October 21, 1928) is an American space physicist, planetary scientist, and distinguished professor emerita of space physics at the University of California, Los Angeles. [1] From 2010 to the present, concurrent with her appointment at UCLA, Kivelson has been a research scientist and scholar at the University of Michigan. Her primary research interests include the magnetospheres of Earth, Jupiter, and Saturn.

Recent research has also focused on Jupiter's Galilean moons. She was the principal investigator for the magnetometer on the Galileo Orbiter that acquired data in Jupiter's magnetosphere for eight years and a co-investigator on the FGM (magnetometer) of the earth-orbiting NASA-ESA Cluster mission. She is actively involved as a co-investigator on NASA's Themis mission, the magnetometer team leader for NASA's Europa Clipper Mission, as a member of the Cassini magnetometer team, and as a participant in the magnetometer team for the European JUICE mission to Jupiter. Kivelson has published over 350 research papers and is co-editor of a widely used textbook on space physics (Introduction to Space Physics). [3]

Early life and education

Kivelson was born in New York City on October 21, 1928. Her father was a medical doctor and her mother had an undergraduate degree in physics. [2] Kivelson knew in high school that she wanted to pursue a career in science, but was unsure whether she would be successful with the career. Her uncle advised her to become a dietitian knowing that pursuing a physical science career as a woman would be hard, but she ignored this advice and began to study physics. Kivelson was accepted into Radcliffe College, Harvard's women's college in 1946, obtained her A.B. degree from Radcliffe in 1950, completed her master's degree in 1952, and was awarded her Ph.D. in physics from Harvard in 1957. [4]

Career

Kivelson completed her PhD thesis "Bremsstrahlung of High Energy Electrons' in 1957. Her thesis provided an expression for the cross section of forward scattering to all orders in the Coulomb interaction. [2]

From 1955 to 1971 Kivelson worked as a consultant in physics at the RAND Corporation based in Santa Monica, California. Here she researched the interactions of plasmas and electron gases using mathematical techniques similar to those in quantum electrodynamics. Working with Don DuBois, they derived a correction to Landau's relation for the damping excitations of unmagnetized plasma. [5] For 1965-1966, Kivelson took a leave from RAND to join her husband's sabbatical leave in Boston. Through a fellowship from the Radcliffe Institute for Advanced Study, Kivelson was able to conduct scientific research in a university setting at Harvard and MIT. [2]

Motivated by her experiences in academia through the Radcliffe Institute, Kivelson joined UCLA in 1967 as an assistant research geophysicist. Kivelson quickly climbed through the ranks within the geophysics and space physics community becoming a full professor at UCLA's department of earth and space sciences in 1980. She chaired the department of earth and space sciences from 1984 to 1987 and from 1999 to 2000. From 1977 to 1983 Kivelson served on the board of overseers at Harvard College as well as NASA's advisory council from 1987 to 1993, the National Research Council's Committee on Solar-Terrestrial Research from 1989 to 1992, and co-chaired the UCLA Academic Faculty Senate's Committee on Gender Equality issues from 1998 to 2000. [4] In 2009 she became a distinguished professor of space physics, emerita and in 2010 she also took a position as a research professor at the University of Michigan. [3]

Scientific contributions

Kivelson has had a very successful career as a scientist that include many publications and original work. [1] Some of her accomplishments are discovering an internal magnetic field at Ganymede, [6] providing compelling evidence for a sub-surface ocean at Europa, [7] and elucidating some of the processes explaining the behavior of ultralow frequency waves in the terrestrial magnetosphere, [8] the discovery of cavity mode oscillations in the magnetosphere, [9] developed new ways of describing wave-particle interactions in magnetohydrodynamic waves, [10] and provided insight into the mechanism of interchange diffusion in rotating plasmas. [11] This research has led Kivelson to being an author or co-author on over 350 publications that have accumulated over 12,000 citations. [12]

Establishing a scientific career as a woman

Some of her recollections about establishing a career as a woman scientist have been documented in an interview by the American Astronomical Society and piece in the Annual Review of Earth and Planetary Sciences . When Kivelson started to pursue her undergraduate degree in physics her family joked she was really pursuing a "Mrs" degree. Before World War II, courses at Radcliffe were segregated by gender from courses at Harvard. However, when Kivelson attended Radcliffe/Harvard in the first class after the war, classes did not return to being segregated. Kivelson was often the only woman in her courses. [2]

Over the course of Julian Schwinger's career he had more than 70 graduate students and of these Kivelson was his only female student. In 1954, she gave birth to her first child, Steven Kivelson, now a professor of physics at Stanford, and afterwards she often faced criticism for continuing to work despite being a mother. In 1955 her husband received an appointment at UCLA and she followed him to Los Angeles. She started working part-time at the RAND Corporation while completing her thesis. A few months after receiving her PhD in 1957, she gave birth to her second child, Valerie Kivelson, now a professor of history at the University of Michigan. [2] [13]

In 1973, Kivelson won a Guggenheim Fellowship to work at the Imperial College in London. According to her, "that fellowship gave me for the first time the sense that I was being taken seriously as a scientist. More than money, it gave me status and increased my self-confidence considerably." [2]

In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. It is created by a celestial body with an active interior dynamo.

<span class="mw-page-title-main">Magnetosphere of Saturn</span>

The magnetosphere of Saturn is the cavity created in the flow of the solar wind by the planet's internally generated magnetic field. Discovered in 1979 by the Pioneer 11 spacecraft, Saturn's magnetosphere is the second largest of any planet in the Solar System after Jupiter. The magnetopause, the boundary between Saturn's magnetosphere and the solar wind, is located at a distance of about 20 Saturn radii from the planet's center, while its magnetotail stretches hundreds of Saturn radii behind it.

Cluster II is a space mission of the European Space Agency, with NASA participation, to study the Earth's magnetosphere over the course of nearly two solar cycles. The mission is composed of four identical spacecraft flying in a tetrahedral formation. As a replacement for the original Cluster spacecraft which were lost in a launch failure in 1996, the four Cluster II spacecraft were successfully launched in pairs in July and August 2000 onboard two Soyuz-Fregat rockets from Baikonur, Kazakhstan. In February 2011, Cluster II celebrated 10 years of successful scientific operations in space. In February 2021, Cluster II celebrated 20 years of successful scientific operations in space. As of March 2023, its mission has been extended until September 2024. The China National Space Administration/ESA Double Star mission operated alongside Cluster II from 2004 to 2007.

<span class="mw-page-title-main">Birkeland current</span> Currents flowing along geomagnetic field lines

A Birkeland current is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere. In the Earth's magnetosphere, the currents are driven by the solar wind and interplanetary magnetic field and by bulk motions of plasma through the magnetosphere. The strength of the Birkeland currents changes with activity in the magnetosphere. Small scale variations in the upward current sheets accelerate magnetospheric electrons which, when they reach the upper atmosphere, create the Auroras Borealis and Australis. In the high latitude ionosphere, the Birkeland currents close through the region of the auroral electrojet, which flows perpendicular to the local magnetic field in the ionosphere. The Birkeland currents occur in two pairs of field-aligned current sheets. One pair extends from noon through the dusk sector to the midnight sector. The other pair extends from noon through the dawn sector to the midnight sector. The sheet on the high latitude side of the auroral zone is referred to as the Region 1 current sheet and the sheet on the low latitude side is referred to as the Region 2 current sheet.

<span class="mw-page-title-main">Magnetosphere of Jupiter</span> Cavity created in the solar wind

The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field. Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar System after the heliosphere. Wider and flatter than the Earth's magnetosphere, Jupiter's is stronger by an order of magnitude, while its magnetic moment is roughly 18,000 times larger. The existence of Jupiter's magnetic field was first inferred from observations of radio emissions at the end of the 1950s and was directly observed by the Pioneer 10 spacecraft in 1973.
