| NMS | Operational | The Neutral Mass and velocity Spectrometer (NMS) measures mass composition and velocity of neutral atmospheric species in the 1-40 amu mass and 0.1-2 km/s velocity range. | n/a |  |
| ENAI | Being developed | The Energetic Neutral Atom Imager (ENAI) is used for imaging observations of neutral atoms (H, O) with energies ranging from 10 to 500 keV in the source region of magnetic storms, achieving high temporal, spatial, and energy resolutions. | n/a | |
