What are the children's space paintings?
The pictures of space paintings in kindergartens show the space paintings of children roaming in space and the division scope of space paintings.
There have been two opposing views on the division of airspace, airspace and outer space.
Spatial theory
The idea is to divide the boundary between air space and outer space with a certain space height, so as to determine the applicable scope of two different legal systems.
functionalpsychology
It is considered that the applicable law should be determined according to the function of the aircraft. If it is a spacecraft, its activities are space activities and the outer space law should be applied. If it is an aircraft, its activities belong to aviation activities and should be governed by aviation law; The whole space is a whole, and there is no need to divide air space and outer space.
As far as the "space theory" is concerned, there are roughly the following opinions on determining the lower limit of outer space:
(1) is limited to the highest altitude of the plane flying upwards, that is, 20 ~ 40 kilometers from the ground.
② Divide boundaries according to different air components. Because there is air from the surface of the earth to tens of thousands of kilometers, there are different opinions about tens, hundreds and thousands of kilometers. Some people even think that any place where air is found is air space and should belong to airspace.
(3) The minimum height of the satellite from the ground * *105 ~110 km * * is the lowest limit of outer space.
From 65438 to 0976, eight equatorial countries including Brazil, Colombia, Congo, Ecuador, Indonesia, Kenya, Uganda and Zaire issued the Bogota Declaration. It is claimed that the geostationary orbit over equatorial countries is 35,267 kilometers above the ground, which belongs to the scope of various countries. The above requirements make the delimitation of outer space more complicated. In recent years, some people who hold the "space theory" gradually tend to accept the above third opinion, that is, the lower limit of outer space is about 100 km above the ground. 1975, Italy proposed that 90 km above sea level is the highest limit of airspace and airspace. 1976 The support of Argentina, Belgium and Italy is bounded by altitude 150 km. 1979, the Soviet union suggested that outer space should be located at an altitude of100 ~120km. At the same time, space objects of all countries have the right to fly over the airspace of other countries in order to reach orbit and return to the territory of the launching country. However, some other countries, such as the United States, Britain, Japan and so on. It is considered that from the current situation of space science and technology, it is impossible to stipulate a certain height as the boundary between airspace, airspace and outer space. They stressed that the conditions and time for the delimitation of outer space are not yet ripe.
The United Nations Committee on the Peaceful Uses of Outer Space is still considering the definition and boundary of outer space and the legal status of the geostationary orbit. COPUOS is considering satellite direct television broadcasting, remote sensing by Earth satellites and the use of nuclear power sources in outer space, so as to draft relevant legal principles.
