Elizabeth "Liz" MacDonald is a space weather scientist who works at NASA Goddard Space Flight Center. She is the co-investigator on the Helium, Oxygen, Proton, and Electron Spectrometer on the NASA Radiation Belts Storm Probe mission.

Education[edit]

Elizabeth MacDonald was born to Walla Wallans Bill and Alice MacDonald.[1] MacDonald received a BSc in Physics from the University of Washington, funded by a NASA Space Grant scholarship, in 1999.[2] Her mentor, Ruth Skoug, encouraged her to remain in research.[3] MacDonald completed her postgraduate studies the University of New Hampshire, earning her PhD in 2005.[4]

Career[edit]

MacDonald is interested in plasma mass spectrometry, and has 15 years expertise in instrument development and data analysis/interpretation.

After completing her PhD, MacDonald joined Los Alamos National Laboratory. At LANL she was the Principal Investigator for the Z-Plasma Spectrometer on the Department of Energy Space and Atmospheric Burst Reporting System geosynchronous payload.[5] She also led the Innovative Research and Integrated Sensing team.[6] She was principal investigator for the Advanced Miniaturized Plasma Spectrometer.[7] She received the Los Alamos Awards Program recognition three times.[8]

Between 2009 and 2011 she led the Department of Energy funded Modular Advanced Space Environment Instrumentation.[2] That year, she noticed a spike in Tweets about an aurora borealis.[9][10] In 2013 she became New Mexico Consortium-affiliated researcher in 2013, working on instruments that measure plasma in the near-Earth space environment.[11] She has served on scientific review panels for the National Science Foundation and Los Alamos National Laboratory grants.[12] Today MacDonald works in the Goddard Space Flight Center.[13]

In 2018 MacDonald and her team announced the discovery of a new aurora called Strong Thermal Emission Velocity Enhancement (STEVE).[14] Steve is further south than has even been seen before.[15] The European Space Agency Swam A satellite was used to identify that the charged particles in STEVE were around 6000 °C.[14] It was first observed by Canadian amateur astronomers in 2015.[16][17] MacDonald attributes the faint purple glow to a subauroral ion drift.[18][19] MacDonald published the finding in Science.[20] She is working with NASA to crowd source sightings of STEVE.[21]

Public engagement[edit]

In 2016 in the journal Space Weather, MacDonald and co-workers reported that "citizen scientists are regularly able to spot auroras farther south of an area where prediction models indicated".[22][23][24] MacDonald leads an interdisciplinary citizen science project called Aurorasaurus, which uses social media to predict the Northern Lights during the current solar maximum.[25][26][27] To fund the program, she won a $1 million grant from the National Science Foundation.[8][28][29] The site (Aurorasaurus.org) is managed by Liz MacDonald, Don Hampton and Jason Ahrns at theGeophysical Institute.[30]

In 2017 she described the aurora as a glitter bomb on the website Science Friday.[31] In August 2017, she spoke at the Carl Sandburg Home National Historic Site about the 2017 solar eclipse.[32] MacDonald regularly speakers to high school students and community groups.[33][34]
