CRUISE science | What should be measured | Instrument | When? Necessary constellation? |
---|---|---|---|
Small-scale solar wind turbulence: how they evolve with radial distance | B field, high-res (min – sec – or less) | MPO-MAG | radial alignment, behind shock waves, within planetary magnetic sheats |
Small-scale solar wind structures: magnetic holes, what is their relation to mirror mode waves | B field, high-res (min – sec – or less) | MPO-MAG | behind shock waves, within planetary magnetic sheats |
Large-scale solar wind structures: transient CMEs, ICMEs properties and evolution, interaction of multiple CMEs, CME+SIR interaction | B field, 5-min – hourly | MPO-MAG (particle detector of MMO-MPPE is NOT directly exposed to solar wind), SIXS-P | radial alignment |
SEPs: acceleration | fluxes of energetic particles (energy spectrum, pitch angle distribution), magnetic field configuration | SIXS-P, MPO-MAG, BERM | radial alignment + widely separated longitudes, close to shock waves |
SEPs: transport (cross-field diffusion?) | fluxes of energetic particles (energy spectrum, pitch angle distribution), magnetic field configuration | SIXS-P, MPO-MAG, BERM | alignment along Parker spiral + widely separated field lines |
Large-scale solar wind structures: background solar wind, CIRs – radial evolution, backmapping | fluxes of energetic particles (energy spectrum, pitch angle distribution), B-field, 5-min – hourly | MPO-MAG, SIXS-P | radial alignment |
CIRs – magnetic sector boundaries | fluxes of energetic particles (energy spectrum, pitch angle distribution), B-field, 5-min – hourly | MPO-MAG, SIXS-P | same Parker field line |
CIRs – 3d evolution | fluxes of energetic particles (energy spectrum, pitch angle distribution), B-field, 5-min – hourly | MPO-MAG, SIXS-P | latitudinal separation |
Comets – water production rates in the hydrogen coma (+OH) – Panstarss | EUV (Lyman-alpha) + FUV | PHEBUS | IMEX will calculate when each target intersects PHEBUS FOV |
Comets – particles in the cometary trails | UV, dust impact flux | PHEBUS, MMO-MDM | constantly |
Dust – interplanetary dust distribution in the inner solar system | dust impact flux within the MDM FOV | MMO-MDM (surrounded by MOSIF, but detection possible through MOSIF aperture) | constantly |
Solar corona studies – density fluctuations, velocity of SW | radio occultation measurements, TEC | MORE | BC + Akatsuki, occultation |
General relativity tests | time delay of radio signals | MORE | superior conjunction |
Galactic Cosmic Rays | MCS emission due to bombardment (local radiation background) | MGNS, SIXS-P | constantly |
Gamma-ray bursts: localize the sources | flux density | MNGS | constantly |
Gamma-ray of solar flares | flux density | MNGS | constantly |
