China plans 'KuaFu Mission' for Sun probe

As China steps up its lunar exploration, some scientists
in the country are planning another space project, the "KuaFu Mission", aiming
to study the activities of the Sun.
At the ongoing 36th Committee on
Space Research Scientific Assembly, Tu Chuanyi, a member of the Chinese Academy
of Sciences, said the project, expected to be launched in 2012, will study the
complex Sun-Earth system and improve the space weather forecast.
mission will raise the standard of end-to-end observation of the Sun-Earth
system, and advance scientists' understanding of the basic physical processes
underlying space weather, said Tu, who is also a professor with the Beijing
Tu said the mission is designed to observe the complete
chain of disturbances from the solar atmosphere to geospace, including solar
flares, coronal mass ejections (CMEs), interplanetary clouds, shock waves, and
their geo-effects, such as magnetic storms and auroral activities.
name of the mission comes from an ancient Chinese legend of KuaFu, who tried to
catch the Sun and enter it.
"The KuaFu mission may start at the next
solar maximum, the year of 2012, hopefully, and with an initial mission lifetime
of two to three years," Tu said.
He said the mission is composed of
three satellites: KuaFu-A and KuaFu B1 and B2. KuaFu-A will be located at the
Lagrangian point L1, the point stable with respect to gravitational forces
between the Sun and the Earth, and have solar instruments to continuously
observe the solar activities.
KuaFu B1 and B2 will be in polar Earth
orbits that enable continuous observations of the aurora in northern hemisphere,
which shows the influence of the Sun activities to the Earth, said the
The KuaFu mission is now at the comprehensive review stage,
said Tu, adding that this study will be concentrated on a further review of the
mission objectives and a further decision of the scientific payload.
the same time, the Chinese space industry will conduct preliminary engineering
studies on various technical elements, including satellite platform, launch
strategy, tracking and control as well as data transmission system.
dozen of leading scientists from Germany, France, Belgium, Austria, Canada and
other countries are expected to participate in the project.
chief scientist of space physics and atmosphere science with the Canadian Space
Agency, told Xinhua that the KuaFu mission is of great scientific significance
and would reach the world leading level in this field.
If the mission is
launched as expected, it will be the world's first space project systematically
probing the Sun-Earth environment, he said.
Violent solar activities may
cause malfunction of satellites, disturbance to the communication facilities on
the Earth, and bring danger to the life safety of astronauts, Liu said.
The KuaFu mission may help predict solar activities and enable human to
take measures to prevent damage caused by the solar activities, Liu said.
However, Liu said China still faces many technological problems to
implement the KuaFu project.
