Space tourism refers to the commercial activity of sending private individuals into space for recreational purposes. Companies like Virgin Galactic and Blue Origin are developing spacecraft that can take tourists on short trips beyond Earth's atmosphere, allowing them to experience weightlessness and see the curvature of the Earth. These spaceflights typically last only a few minutes, but they offer a unique opportunity for civilians to experience space travel, which was once limited to professional astronauts. As technology advances and costs decrease, space tourism may become more accessible to a broader audience in the future.
