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. 相似文献

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 相似文献

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. 相似文献

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. 相似文献
