21
ESA Support to Solar-B
  • ESA, in sub-contractual collaboration with the
    Norwegian
  • Space Centre, will provide one additional
    downlink contact
  • to Solar-B for each of the 15 orbits per day
  • This will considerably improve the overall
    scientific data return
  • and the cadence of observations from the
    Solar-B mission
  • The European scientific community
  • will be catered with processed data
  • through a dedicated Solar B data
  • centre at the University of Oslo


22
Svalbard Ground Station for Solar-B
  • Reasons Antenna redundancy,
  • possibility to track all 15 orbits
  • every day and Norwegian
  • interest in the mission.

23

(presently involving more than 25 space
agencies SC CNSA, CSA, ESA, (R)FSA, JAXA,
NASA )
MISSION
  • Stimulate, strengthen and coordinate space
    research
  • to understand the governing processes of the
    connected Sun-Earth system as an integrated
    entity.
  • (governing processes which affect life and
    society gt SpaceWeather)
  • simultaneous and coordinated observations
  • at strategic locations in the entire system
  • (supported by advanced analysis and model tools)

ESAs Cosmic Vision, 2015-2025
  • Themes
  • What are the conditions for life and planetary
    formation?
  • How does the Solar System work?
  • From the Sun to the edge of the Solar System
  • First, the hierarchy of scales in the
    magnetosphere (e.g. M3, Magnetospheric SWARM)
  • Gaseous Giants and their Moons
  • The Building Blocks of the Solar System
    Asteroids and Small Bodies
  • What are the fundamental laws of the Universe?
  • How did the Universe originate and what is it
    made of?
  • Giovanni Bignami, chairman SSAC, 10 May 2005

29
Three scales of plasmas shocks as an example
30
Cross-Scale key concepts
  • Spacecraft on a hierarchy of scales
  • Electron group
  • Electron instruments
  • 3 axis electric and magnetic fields
  • Ion group
  • Fast ion instruments
  • Magnetic field instruments
  • Fluid group
  • Bulk plasma and field instruments
  • Energetic particles
  • Note
  • Need different instrumentation at each scale
  • Other agencies could provide one or more scales

31
Cross-Scale - The ESA context
  • Cosmic Vision 2015-2025
  • Relative to other CV mission concepts,
    Cross-Scale is
  • Cheap lt300M, baseline of single Soyuz-Fregat
    launch
  • Quick early in programme - by 2015?
  • Easy no technological show-stoppers
  • Potential for international collaboration JAXA
  • SCOPE 5-s/c mission for cross-scale plasma
    dynamics
  • Led by M. Fujimoto ISAS
  • First inter-agency discussions at two ESA /JAXA
    Bilaterals

32
European ILWS Strategy in an Overview
33
SCOPE the Japanese connection
  • Proposed ISAS five-spacecraft mission
  • Focus on electron dynamics at shocks and
    reconnection sites
  • Potential for incorporating SCOPE as the inner
    scale of Cross-Scale
  • This is only one possible scenario!
