She was also a project manager on NASA’s Galileo mission to Jupiter and was a member of the technical staff at the Jet Propulsion Laboratory. As a researcher, Alexander’s studies included the evolution and interior physics of comets, Jupiter and its moons, magnetospheres, plate tectonics, space plasma, the solar wind and the planet Venus. She wrote or co-authored 14 papers.
