Carr designs, builds and calibrates fluxgate magnetometers for planetary and heliophysics space missions (including ESA's JUICE and BepiColombo), covering everything from sensor electronics to in-flight calibration of magnetic-field instrumentation.

Horbury is Principal Investigator for the magnetometer instrument on ESA's Solar Orbiter mission, studying solar-wind turbulence and the Sun's magnetic connection to the heliosphere through in-situ spacecraft instrumentation.
