The invention discloses a tethered balloon with a telescopic gasbag body, to enable the balloon to ascend to the sky. A telescopic gasbag structure is adopted, and the principle that the pressure inside and outside the gasbag is in balance is adopted, when the balloon ascends to the sky from the ground, the telescopic gasbag can be expanded to a required size along with the continuous decrease of the outer environment air pressure, when the balloon returns to the ground from the sky, the gasbag can be shrunk to the original size along with the continuous increase of the outer environment air pressure, thus the shape and safety of the balloon are guaranteed, and hang time of the balloon can be doubled.
