Introduction to space weather

The solar and interplanetary origin of space weather disturbances, as well as the related magnetospheric dynamics, will be presented. Besides the involved phenomenology in solar–terrestrial physics, some of the main effects of space weather variability concerning mankind in space and at the earth’s surface will also be discussed. The November 2003 event is shown as an example of the solar, interplanetary and magnetospheric aspects of a space weather storm.     

Introduction to Chinese Meridian Project-Phase II

The Chinese Meridian Project is a ground-based space environment monitoring network, which is constructed in two steps. The first step (Phase I) of the project consists of 15 observation stations located roughly along 120°E longitude and 30°N latitude. The second step (Phase II) of the project will additionally deploy 16 stations to better cover China's territory, and build a stereo monitoring capability to monitor the cause and effect of the space weather chain in the solar terrestrial system. Based on the existing two monitoring chains in Phase I, two more chains will be established along 100°E longitude and 40°N latitude, respectively, forming a double-cross network configuration. After the two-step construction, the whole project will run nearly 300 instruments deployed at 31 stations. Aside from standard instruments, quite a few innovative and powerful instruments will be developed, such as radioheliographs with a very wide frequency band, a 3-station incoherent scattering radar to make a 3D measurement of the ionosphere, and a helium lidar to measure atmosphere density up to an altitude of 1000 km.      

Brief Introduction about the SVOM Mission

SVOM is a mission dedicated for studying γ-Ray Bursts, and will also be a powerful target-ofopportunity observatory for the whole astronomy community. The mission has been approved jointly by both Chinese and French space agencies. It is planned to be in the orbit in 2021 with an altitude ≤ 600 km and an inclination ≤ 30°.     

漫谈小行星及其探测与开发

正2017年5月8日上午,"叶培建星"命名仪式暨小行星探测学术报告会在中国空间技术研究院举行。"叶培建星"国际编号为456677,由中国科学院紫金山天文台于2007年9月11日发现。为了表彰我国著名航天专家叶培建院士为推动我国月球与深空探测及空间科学快速发展所做出的突出贡献,2016年6月紫金山天文台推荐命名"叶培建星",2017年1月12日获国际小行星命名委员会批准。自此,"叶培建星"正式镶嵌进太空星辰,     

长征－11：小火箭、大用途

2016年11月10日7：42,长征－11 Y2固体运载火箭在中国酒泉卫星发射中心发射成功,这是继2015年9月25日长征－11火箭首飞成功后正式执行应用发射。此次发射以“一箭五星”的形式成功将首颗“脉冲星试验卫星”、2颗30千克级皮纳－2卫星、1颗3千克级丽水－1试验卫星和1颗10千克级潇湘－1试验卫星高精度送入太空。目前,5颗卫星运行状态良好,正按计划开展相关的空间试验和卫星应用。     

Introduction to Meridian Space Weather Monitoring Project

The Meridian Project is a ground- based network program to monitor solar-terrestrial space environment, which consists of a chain of ground-based observatories with multiple instruments including magnetometers, ionosondes, HF and VHF radar, Lidar, IPS monitors, sounding rockets etc. The chain is mainly located in the neighborhood of 120°E meridian, and is thus named the Meridian Project. It has officially been approved by the Chinese government and will be finished by 2009. This talk will give an overview of the Meridian Project and the proposed International Space Weather Meridian Circle Program.
