REAL [Dartmouth]

REAL (Relativistic Electron Atmospheric Loss) is a scientific investigation mission conducted by Dartmouth Collegemission designed to characterize the loss of particles from Earth’s Van Allen radiation belts. REAL will carry an energetic particle instrument that is sensitive to both electrons and protons. From its vantage point in low-Earth orbit, REAL will point its instrument along Earth’s magnetic field to measure radiation belt particles as they enter the atmosphere.

REAL is built on a 3U CubeSat satellite bus. The REAL particle detector instrument will constitute the top 1/4 U of the 3U REAL spacecraft. Each of the medium- & highenergy apertures resolves a 20° range of electron pitch angles. The first Look-Direction (LD) will be centered on the magnetic field, so it has a 40° Field-of-View (FoV).

It was selected in 2020 by NASA's CubeSat Launch Initiative (CSLI) program by the CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program.
