applying the same principles to outer space. Several nations have enacted or recently updated their national space law, for example, Luxembourg in 2017, the United States in 2015, and Japan in 2008. Due to the expansion of the domain of space research and allied activities in India, the Draft Space Activities Bill was introduced in the year 2017. Defining "space" Many questions arise from the difficulty of defining the term "space". Scholars not only debate its geographical definition (i.e. upper and lower limits), but also whether or not it also encompasses various objects within it (i.e. celestial objects, human beings, man-made devices). Lower limits are generally estimated to be about 50 kilometers. More difficulties arise trying to define the upper bounds of "space", as it would require more inquiry into the nature of the universe and the role of Earth as a planet. Geostationary orbit allocation Allocative limitations Objects in geostationary orbits remain stationary over a point on the earth due to gravity. There are numerous advantages in being able to use these orbits, mostly due to the unique ability to send radio frequencies to and from satellites to collect data and send signals to various locations. The United Nations Committee on Peaceful Uses of Outer Space has approved seven nonmilitary uses for these orbits: communications, meteorology, earth resources and environment, navigation and aircraft control, testing of new systems, astronomy, and data relay. The requirement to space these satellites apart means that there is a limited number of orbital "slots" available, thus only a limited number of satellites can be placed in geostationary orbit. This has led to conflict between different countries wishing access to the same orbital slots (countries at the same longitude but differing latitudes). These disputes are addressed through the ITU allocation mechanism. Countries located at the Earth's equator have also asserted their legal claim to control the use of space above their territory, notably in 1976, when many countries located at the Earth's equator created the Bogota Declaration, in which they asserted their legal claim to control the use of space above their territory, but failed to challenge the Outer Space Treaty in this regard. Political controversy Future developments using geostationary orbits may include an expansion of services in telecommunication, broadcasting, and meteorology. As a result, uses for geostationary orbits may stir political controversy. For example, broadcasting and telecommunication services of satellites orbiting above Earth from
