11 scientific experiments including also carries two 5 meter-long experiment booms, four 50 meter-long wire booms, and two antenna booms:

1: Fluxgate Magnetometer (FGM) to provide magnetic field components
2: Electron Drift Instrument (EDI) to enable inference of electric field vector in the vicinity by recapturing the emissions from an electron gun
3: Active Spacecraft POtential Control experiment (ASPOC) in which positive indium ions are shot in order to neutralize the build-up of positive charges on a spacecraft
4: Spatio-Temporal Analysis of Field Fluctuation experiment (STAFF) to do in situ analysis of the fluctuations in the magnetic field
5: Electric Field and Wave experiment (EFW) to measure the electric field and plasma density fluctuations
6: Digital Wave Processing experiment (DWP) to enable in situ correlations of waves and plasma density
7: Waves of HIgh frequency and Sounder for Probing Electron density by Relaxation experiment (WHISPER) which excites local plasma oscillations synchronous with the pulsed radio emissions
8: Wide Band Data instrument (WBD) which monitors the B- and E-fields of natural VLF emissions such as whistlers
9: Plasma Electron And Current Experiment (PEACE) which enables 3-D distribution function of cold and hot electrons
10: Cluster Ion Spectroscopy experiment (CIS) to monitor the charge, mass, and distribution function of hot and cold ions
11: Research with Adaptive Particle Imaging Detectors (RAPID) to monitor the arrival direction of very high energy electrons and ions, and their energies.
