  • Length and Time Scale in GeospaceExample of the various scale lengths and time scales present in the near-Earth environment. The smallest lengths and shortest timescales correspond to electron dynamics, followed by ion scales to eventually the fluid scales that set the context and driving conditions for the phenomena of interest.The coupling between the various scales requires measurements at least two scales simultaneously.

  • Cross-Scale Mission StudyThe Cross-Scale mission has been the subject of an assessment study as part of ESAs Cosmic Vision Plan for the ESA Science ProgrammeCross-Scale is an M-Class mission candidate, due for launch in 2017. The assessment study consisted of two parallel, recently concluded, industrial studies from 2007-2009.Science input was via a Science Study Team, comprising of a group of international scientists (Europe, Japan, US, Canada) led by Professor Steven J. SchwartzIn parallel to the industrial activities, a number of instrument teams or consortia have been working on the scientific payload elements of the mission

  • Cross-Scale Mission Study Baseline
