RAX (Radio Aurora Explorer) is a student-built nanosatellite for ionospheric research. It is built on a triple CubeSat structure.

The RAX will measure the energy flow in the ionosphere, the highest part of Earth's atmosphere where solar radiation turns regular atoms into charged particles.

RAX is a Ground-to-Space Bistatic Radar Experiment. The RAX satellite will act as a receiver that will pick up signals from a ground radar transmitter. These radar pulses will reflect off disturbances, or space weather phenomena, in the ionosphere.
