Its offerings include zero-gravity atmospheric flights, orbital spaceflights, and other spaceflight-related experiences including cosmonaut training, spacewalk training, and launch tours. Plans announced thus far include sub-orbital and lunar spaceflights, though these are not being actively pursued at present. Nine of its clients have participated in the orbital spaceflight program with Space Adventures, including one who took two separate trips to space.

Space tourism is human space travel for recreational purposes. There are several different types of space tourism, including orbital, suborbital and lunar space tourism. Tourists are motivated by the possibility of viewing Earth from space, feeling weightlessness, experiencing extremely high speed and something unusual, and contributing to science.
