Bale directs Space Sciences Laboratory and leads the FIELDS instrument suite on NASA's Parker Solar Probe, which combines search-coil and fluxgate magnetometers with electric-field antennas to make in-situ, high-cadence measurements of the electromagnetic fields threading the solar wind and corona. His group also contributes field instrumentation to Solar Orbiter and other heliophysics missions, pushing the sensitivity and bandwidth of spacecraft field sensors used to study particle acceleration and turbulence.
