Space 2.0
Private spaceflight is any spaceflight development that is not conducted by a government agency, such as NASA or ESA. During the early decades of the Space Age, the government space agencies of the Soviet Union and United States pioneered space technology in collaboration with affiliated design bureaus in the USSR and private companies in the US. They entirely funded both the development of new spaceflight technologies and the operational costs of spaceflight. Following a similar model of space technology development, the European Space Agency was formed in 1975. Arianespace, born out of ESA's independent spaceflight efforts, became the world's first commercial launch service provider in the early 1980s. Subsequently, large defense contractors began to develop and operate space launch systems, which were derived from government rockets. In the United States, the FAA has created a new certification called Commercial Astronaut, a new occupation. In the 2000s, entrepreneu ...

Space Missions Conducted Between 1957 And 2020
Space is a Three-dimensional space, three-dimensional continuum containing position (geometry), positions and direction (geometry), directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional Continuum (theory), continuum known as ''spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are Non-Euclidean geometry, non-Euclidean, in which space is conceived as ''space curvature, curved'', rather than ''flat space, flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
