An airship is a powered, free-flying aerostat that can be steered. Airships divide into rigid, semi-rigid and non-rigid types, with these last often known as blimps. A rigid airship has an outer framework or skin surrounding the lifting gas bags inside it, The outer envelope keeps its shape even if the gasbags are deflated.
The amount of mass that can be lifted by hydrogen in air per unit volume at sea level, equal to the density difference between hydrogen and air, is: (1.292 - 0.090) kg/m 3 = 1.202 kg/m 3. and the buoyant force for one m 3 of hydrogen in air at sea level is: 1 m 3 × 1.202 kg/m 3 × 9.8 N/kg= 11.8 N
Space: 1889 is a science-fiction role-playing adventure game based on the Space: 1889 role-playing game by Game Designers' Workshop.The game is set in the 19th-century Victorian era, a world where interplanetary travel was already achieved, and discoveries have taken place like the antigravitational liftwood on Mars in 1870 as well as hydrogen-filled airships.
The Giffard dirigible or Giffard airship was an airship built in France in 1852 by Henri Giffard, it was the first powered and steerable airship to fly. The craft featured an elongated hydrogen -filled envelope that tapered to a point at each end.
The Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System, or JLENS (colloquially, Spy Balloon), [1] was a tethered aerial detection system designed to track boats, ground vehicles, [2] cruise missiles, manned and unmanned aircraft (airborne early warning and control), and other threats [specify].

A balloon is a form of aerostat, along with the powered free-flying airship, although the American GAO has used the term "aerostat" to describe a tethered balloon in contrast to the powered airship. [1] Tethered balloons have been used for advertising, recreation, observation, and civil or military uses.
