UCLA is recognized internationally as a leader in the plasma physics of space. Research done by the space physics group includes data analysis, simulation, modeling, and theoretical plasma physics. Topics of interest include the dynamics of the solar wind, the magnetospheres of the Earth and planets, and the interaction of the solar wind with bodies in the solar system including asteroids, planetary satellites, unmagnetized planets, and planetary magnetospheres. Recent work includes studies of loss processes in planetary atmospheres and the occurrence of lightning in planetary atmospheres. Much effort is being expended towards the understanding of terrestrial magnetospheric activity including geomagnetic storms and substorms. One of the ways that UCLA contributes to our understanding of the magnetized space plasma environment is through building and flying magnetometers on exciting missions of discovery. Magnetometers designed and fabricated at UCLA have enabled space science faculty and students to greatly expand our understanding of the magnetic structure and dynamics of the Earth, Venus, Jupiter, their satellites, asteroids, and the solar wind.
