Space Science Plan 2010-2025Space Science Plan 2010-2025• Chinese Academy of Science is conducting a study for a

space science plan 2010-2025• The study includes

– A survey of basic research force in China in space science, it turned out that the number of manpower is around 4000, in the areas of space astronomy, space physics/exploration, microgravity science and space life science

– A review of NASA, ESA, Roscosmos, JAXA, ISRO, and other nations space strategy and plans

– A study of fundamental scientific problems that should be solved– Roadmaps (with mission plans) to give solutions to those proble

ms– Technology support requirement to implement the proposed mis

sions– Publication of this plan will be released later this year

• SMESE - Small Mission of Exploration on Solar Eruptions– An approved Sino-French mission in Phase A– Will have good contribution on Solar eruption

studies including flares and CME, and will have good contribution to ILWS

– Currently on the French side has some difficulties to go ahead due to programmatic reasons, final decision may be made Apr.09

– Still wish to launch it by 2012-2013

SPORT - Solar Polar Orbit Radio Telescope SPORT - Solar Polar Orbit Radio Telescope – To imaging the high density plasma clouds at radio wave

band from solar polar orbit– Provide measurement evidence to the numerical model of

ICME propagation– Provide interplanetary space weather forecast– In-situ Measure the global distribution of solar wind– Discover the heating, accelerating and super radial

dilation of solar wind– Obtain the distribution and total output of solar angular

momentum

Spatial resolution requiredIn order to follow the ICME explicitly, a 20x20 cells within 1 AU is necessary

Which correspond a spatial resolution ability of < 4.5 deg.Which correspond a spatial resolution ability of < 4.5 deg.

At 15MHz, this require a physical antenna aperture of 270mAt 15MHz, this require a physical antenna aperture of 270m

Remarks

• China is a developing country that the national space policy is certainly focus on application satellite, not scientific satellite!

• However, a few missions can be supported if it has significant scientific value and international participations

• CNSA is under government reform. Future plans will be re-confirmed by a new organization later this year

Magnetosphere, Ionosphere and Thermosphere Coupling

Project(MIT Coupling Project)

• The triggering processes of magnetospheric substorms: the effects and interaction between the magnetic field fluxes tailward and earthward; the effect of solar wind and the energy transfer from solar wind to magnetosphere via dayside magnetopause.

• O+ outflow fluxes, their variations with geophysical conditions, and their relationship with geomagnetic substorm/storm dynamics.

Science Objectives
