MAJIS GCO-5000 limb observations
Latitudinal scanning of the diurnal limb at 1 km at different latitudes; study of the variability of the exospheric processes (sputtering, photodissociation, sublimation). Observe polar (north/south) and equatorial latitudes ; perform long-term and high-temporal-resolution monitoring.
Pointing: S/C limb tracking at locations where the slit is tangent to the limb
Satellite orientation: Off-nadir orientation, Slit tangent to the limb
Duration: 600sec




~25 cubes for full limb coverage A minimum of 3 (north,equat,south) x 2 (dawn, dusk) positions. Limb observation from the night side also possible with lesser conflicts with nadir surface observations with the main goal to monitor plume spatial structure (high solar phase angle). Synergy with JANUS. High phase angle constraints are the most meaningful for plume observations
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
conditions that make the observation not possible (e.g. thruster firing)
