    China launched its first lunar probe, Chang’E-1, at 6:05 p.m. (10:05 GMT), Oct. 24, 2007. Chang’E-1 blasted off on a Long March 3A carrier rocket from the No. 3 launch tower in the Xichang Satellite Launch Center of southwestern Sichuan Province. China National Space Administration performed the lunar orbit injection maneuver for Chang’E-1 at 11:25 a.m. on Nov 5, 2007 (China Standard Time). Chang’E-1 was injected into the lunar orbit after the maneuver, and will begin to explore the moon in the following one year. It is the first step into its ambitious three-stage moon mission, marking a new milestone in the Chinese space exploration history. This paper introduced the every important maneuver work of Chang’E-1 experienced from launch till to 20, Nov, 2007.

    The discovery of giant magnetoresistance effect (GMR) is not only very important in science, but ignites the technical innovation of the magnetic storage. It is the first time that the spin degree of freedon was widespread use in everbody's life.The new field of spintonics which studies the spin properties of all kinds of material after the discovery of GMR was opened.

    The microgravity in out space provides human being a quite special environment for exploring new laws and new preparation methods of materials, because the convection, deposition, floating, and hydrodynamic pressure, which have great effects on the preparation of materials, disappear in microgravity environment. The internationally historical and current studies on materials under microgravity, and the study results in this field achieved in China are introduced in this paper.

    All life on the earth has usually evolved within the force of earth’s gravitational field and has acquired the ability to gravistumili to regulate their growth and development. Although the directional growth of plants in response to gravity has continued been studies for over a century, but the cellular and molecular mechanisms underlying the gravitropic response of plants still remain to be understood. The cytoskeleton is considered as an important organelle in mediating early sensing and signal transduction events in plant gravitropism. There are a lot of evidences indicating that the role of actin cytoskeleton in regulating auxin polar transport, which induces a lateral gradient of auxin and results in plant organ curvature. The reorientation of microtubules in plant cells during gravitropic response was also reported, but the role of this reorganization of microtubules in controlling the differential gravitropic growth has not been clear. The advances in cellular, molecular and biochemical techniques have provided several possibilities for further research into this fascinating area. The new findings in characterization of cytoskeleton binding proteins have provided us a lot of useful information on various kinds of candidate regulators that could be targets of the gravity signal transduction chain. In this paper, the functions of cytoskeleton in gravitropism are discussed and the update progress in plant space biology is also introduced.
