Double Star ProgramDouble Star Program
• TC-1 and TC-2 is expecting to end its lifetime by Oct. 2007
• Perigee of TC-1 is changing (down) rapidly
• Altitude of TC-2 is about 42 deg. from the north pole, which effected the antenna pattern and communication link

Status of KuaFu Mission Status of KuaFu Mission
• CNSA has supported two background project studies – Scientific objectives and payloads
selection– Spacecraft feasibility
![Page 8: China National Report 11-0-2007, Uppsala, Sweden China National Space Administration.](https://reader030.fdocuments.in/reader030/viewer/2022032414/56649ef15503460f94c024f0/html5/thumbnails/8.jpg)
Status of KuaFu Mission Status of KuaFu Mission
• The 2nd International Symposium on Kuafu project was held in Sanya, Haiyan, 14-20 Jan. 2007
• Review for the Scientific Objectives Payload Selection have just been finished 1 June, 2007, with a strong support from the scientific community
• Review for the s/c feasibility is going to be held soon

Status of KuaFu Mission Status of KuaFu Mission • Current problem is still on the possibility of
early start of the engineering phase and to launch is around 2012
• CNSA is considering it a background study and may discuss start of the engineering phase early only if there is extra fund available
• International cooperation is very welcome and will certainly be very helpful to speed up the project including providing spacecraft

SMESESMESE
• 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
– 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 CME explicitly, a 20x20 cells within 1 AU from the Sun should be enough
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

Other Missions Under StudiesOther Missions Under Studies
• Scientific Objectives of MIT• Global neutral wind and temperature variations during
geomagnetic storms; seasonal and diurnal effect on these variations; recovery of the thermosphere and ionosphere after storms
• Global electric field distributions during geomagnetic storms, their temporal and spatial variations, and their changes with ionospheric conductivity
• The generation, propagation and dissipation of large scale gravity waves in the thermosphere/ionosphere during and after the storms

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 support if it has significant scientific value and international participations
• Scientists from China is very much like to give our contributions to the ILWS

Possible New Task Group for Heliosphere
• Solar task group is very big if it still takes care of the heliospheric space
• The Inner-Interplanetary region is the key region of space weather forecast
• ICME propagations has not being our attention• Deep space exploration missions need to know t
he heliospheric environment• Interaction of solar wind with other planets • Study of the termination shock, the bounder of o
ur solar system, should be included in ILWS also
