Space tourism refers to the commercial activity of sending private individuals into space for recreational, leisure, or adventure 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 trips typically last a few minutes and involve a suborbital flight, where passengers ascend to the edge of space before returning to Earth. As technology advances and costs decrease, space tourism is expected to become more accessible, potentially opening up new opportunities for exploration and adventure.
