The difference between a balloon and an airship is that

Balloons can't fly automatically, while airships have devices to propel and control the flight state, and have their own power system, so they can fly by themselves.

The biggest difference between balloons and airships is that balloons can't fly automatically, while airships have devices to propel and control the flight state, have their own power system and can fly by themselves. The tail surface is used to control and maintain the stability of heading and pitching.

Xu, general manager of Daejeon airship, said that airship and balloon belong to aerostat, which is the sounding balloon in the mouth of ordinary people. They can be used to observe scientific research, meteorological and geological disasters, and play a role in forecasting ocean circulation and severe weather. At present, the domestic sounding balloon is in the research and development stage and has not yet entered the industrialization stage.
