As part of this assignment, it may be possible to have space participants as part of an expedition as soon as the ISS has a crew of more than three people. Visiting Crewmembers travel to and from the ISS, but are not members of the expedition crew. Therefore, they are not considered to be the use by a sponsoring agency of flight opportunities or crew time rights. You can be either professional astronauts/cosmonauts or space participants. The LSC first emphasized the development of general principles on the exploration and use of outer space, which led to the adoption in 1963 of the United Nations General Assembly resolution “Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space” (UN GA Res., 1962, Declaration of Legal Principles). This statement was about the rescue and return of astronauts in principle 9: the Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Space, also known as the Rescue Agreement, is an international agreement that defines the rights and obligations of States with respect to the rescue of people in space. . . .
