ILWS missions in the
next 5 years
Sino-Russian Mars Exploration (YH-1)
 An agreement has been reached between the Chinese and Russian
Space Agencies in March 2007 to piggy-back launch a Chinese
micro-satellite “Ying Huo-1” (YH-1) together with Phobos-Grunt.
 Launch: 2011.11
 Science objectives:
To study in details the plasma
environment and magnetic fields of
Martian space;
To study Martian ionosphere profile,
particularly on the day and night
sides;
To study the relation between sand
storm and ionosphere;
To improve the Martian gravity field
near equator plane.

KUAFU
 Scientific Objectives：
To observe the complete chain of disturbance from the solar
atmosphere to the geo-space:
 Solar flares, CMEs,
 Interplanetary clouds, shock waves,
 Their geo-effectiveness, such as sub-storms and magnetic
storms, aurora activities

Magnetosphere－Ionosphere－Thermosphere
Coupling Exploration (MIT)
 Scientific Objectives ：
 To understand the origin, acceleration and transport of ionospheric
ions into the magnetosphere;
 To investigate the importance of the outflows from the
ionosphere/thermosphere on the geomagnetic substorm/storm
dynamics;
 To examine global multi-scale variations during geomagnetic storms;
 To reveal the key mechanisms of coupling among the magnetosphere –
ionosphere – thermosphere coupling system.

Solar Polar Orbit Radio Telescope (SPORT)
Science Objectives: SPORT will be the first mission to image the
propagation of CME continuously off the ecliptic plane. Specific science
objectives are the followings
 To characterize the propagation and evolution of CME events;
 To establish the chain physical model and prediction model of interplanetary space
and geospace weather in response to CME and its interplanetary disturbance
response;
 To derive the physical parameters of plasmas inside the CME;
 To detect in-situ the distribution of solar wind in the interplanetary space and
develop a model of the magnetic topology, temperature, density, and velocity
structure of the solar wind;
 To understand the interaction process of magnetic field and plasmas;
 To detect solar short-time radio bursts and establish the chain change physical
model.
