Cluster is an ESA mission launched in 2000 and consisting of four identical spacecraft flying in a polar orbit. THEMIS is a NASA mission launched in 2007 with five identical spacecraft flying in an equatorial orbit. This constellation of nine spacecraft enables researchers to study, in an unprecedented way, major physical processes taking place in the environment of Earth including: collisionless shock formation and evolution, magnetic reconnection, solar wind particle entry into the Earth's magnetosphere and particle acceleration during geomagnetic substorms.

The four-day workshop was organized in a number of plenary sessions during which the participants discussed new results from both missions. Highlights from the plenary sessions can be accessed via the links below:

	Solar wind, bow shock and magnetopause(conveners: H. Kucharek, S. Schwartz and D. Sibeck)
	Magnetopause, polar cusp, transients and FTEs (conveners: D. Sibeck, T. Phan, B. Lavraud)
	Magnetotail and substorms (conveners: H. Frey, L. Kepko, A. Runov)
	Inner magnetosphere (conveners: I. Mann, O. Santolik, X. Li, J. Goldstein)

Individual presentations from the workshop are also available online (see link to "First Joint Cluster-THEMIS workshop: presentations" on the right-hand menu).
