Its called a space elevator, and it’s on the fringe of feasible with current technology. The concept is a counterweight tethered to a station on earth, not unlike a track-and-field hammer throw. Then you could move up and down the tether. There would have to be some pretty significant advances in materials science before it’d be practicable, though. The benefits would be that it’d vastly reduce the cost of getting mass to orbit, and make large scale orbital construction a reality.
