PPT-A multi-spacecraft analysis of energy transfer associated with near-Earth magnetic reconnection

S Fadanelli B Lavraud F Califano We present an analysis of energy transfers in a reconnecting nearEarth plasma obtained by interpreting MMS data within the framework of multifluid plasma theory In our analysis energy transfers are calculated and examined locally This way correlations between different mechanisms of energy exchange can be retrieved in all spatial and temporal detail provided by the highfrequency multipoint sampling capacity of the four MMS satellites .

Before, you learned. • The motions of planets and other nearby objects are visible from Earth . • Light and other forms of radiation carry information about the universe. Now, you will learn. • How astronauts explore space near Earth .
