A space elevator is a proposed transportation system that would use a cable or structure extending from Earth's surface into space to carry cargo and people into orbit, potentially making space access much cheaper and more efficient than rockets. While it remains theoretical and faces significant engineering challenges, scientists and engineers view it as potentially transformative for space exploration and commerce because it could dramatically reduce the cost of reaching space compared to conventional launch methods.
