Integrated Studies of Electric Propulsion Engines during Flights in the Earth’s Ionosphere

Fifty years ago, on October 1, 1966, the first Yantar satellite laboratory with a gas plasma–ion electric propulsion was launched into orbit as part of the Yantar Soviet space program. In 1966–1971, the program launched a total of four laboratories with thrusters operating on argon, nitrogen, and air with jet velocities of 40, 120, and 140 km/s, respectively. These space experiments were the first to demonstrate the long-term stable operation of these thrusters, which exceed chemical rocket engines in specific impulse by an order of magnitude and provide effective jet charge compensation, under the conditions of a real flight at altitudes of 100–400 km. In this article, we have analyzed the potential modern applications of the scientific results obtained by the Yantar space program for the development of air-breathing electric propulsion that ensure the longterm operation of spacecraft in very low orbits.     

The Development of the Chinese Academy of Space Technology

The Chinese Academy of SpaceTechnology (CAST),officiallyfounded on Feb.20,1968,has ahistory of 25 years.Now it is aworld-famous space organizationwith a considerable size.CAST has14 research institutes and factoriesall over the country with more than11 thousand staff and workers in-cluding over 6000 technicians(about 1700 high and middle ranktechnical experts).Now it is spe-cialized in many areas,such asspacecraft system,structure,thermal control,attitude control,orbit control,electronics telemetry,

Effect of Space Law on Space Activities

In recent years, people have made increasing studies and discussions on the relationship between the law and space activity. Some famous space law scholars in the world have put forward the opinions of "impact of the development of space technology on the law of outer space" and "development of space law as a result of astronautical technology", which show the fact that space activity and law infiltrate and influence each other. Space technology has played a leading role in the generation and development of space law. The paper quite agrees with the above mentioned opinions, but tries to describe     

The Development and Application of Ground Systems and Derived Systems of Space Technology

In this paper,the development ofsatellite ground systems and non-satellite equipments and systems de-rived from satellite technology inthe Chinese Academy of SpaceTechnology is reviewed.Satelliteground systems include those fortracking,monitoring and controlfor the launch and operation ofsatellites as well as transmitting andreceiving system for dedicated andindividual users.Derived systemsand equipment include some ofspinoff from satellite technologies,such as computer measurement andcontrol,attitude control,thermalcontrol,radio electronic technique,vacuum technique and new materi-als.They are related to the eco-nomic and social benefits derivedfrom the development of space tech-nology.

Research On The Protection Of The Space Environment In China

To control the generation of space debris is one of the emphases of space debris study in China. We should understand the significance of the research on the mitigation of space debris from the point of view of the outer space environment protection. This paper briefly introduces the main achievements made in the field of space debris mitigation in China last year and the main ongoing research activities. The ideas for future research on space debris mitigation in China are also Odescribed.     

Spin-off of China's Space Technology

Based on the space section of the former Ministry of Aerospace Industry, China Aerospace Corporation was set up in June, 1993. It is a very large nationwide science, technology and industry corporation, which combines the military with civilian technology and industry with trade.
