Coordinated Observations between MPO and MMO

Harri LaaksoESA/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
