Coordinated Observations between MPO and MMO Harri Laakso ESA/ESTEC, Noordwijk

Introduction Scientific output of the mission will increase significantly by collecting coordinated observations between MPO instruments between MMO instruments between MPO and MMO instruments We can ignore here instrument suites (and those who share their DPU) as the suites will take care of their coordinated observations Why now? - To find out  key links between instruments for operations planning & commanding cycle  requirements on the mission level (e.g., mass memory, telemetry, power etc) √√√√

Aspects on Coordinated Observations  Analysis of the observations by one instrument requires/needs other data from another instrument  Simultaneous data?  Does it need to be collected at the same time (within a second or minute) or  Is it enough to be collected within a few hours (i.e., slowly varying features) or (nearly) any time during the mission (I.e., permanent features)  Which variable? And instantaneous, spin-average, or what?  How frequently?  Is it enough that it is done on a campaign basis; e.g. for calibration purpose, and if so, once a week or what?  Does it have to be done regularly, i.e., the other data are essential input data?  Are the other data needed onboard or on ground?

Synergies between MPO and MMO Two-point observations  Simultaneous two-point observations are always valuable and in planetary environments quite rare Supporting data  Analysis of the observations from one spacecraft require/need additional data, e.g., about environment & conditions given by the other spacecraft, such as  MPO needs solar wind and/or magnetospheric data from MMO  MMO needs solar and/or planetary data from MPO
