G. Arelsky, in his essay “The Tale of Mars,” describes the following device for the interplanetary spaceship “airmobile,” with the help of which the inhabitants of Mars communicated with the Earth. The airship was built on the principle of a planet. Like a planet, it was surrounded by an atmosphere formed from a special gas produced inside the apparatus. This gas jacket protected the apparatus from the cold of airless space and resolved all previously insoluble difficulties. The device took energy from the sun's rays. After the first experiments of successful flights to Earth, the Institute of Interplanetary Communications (interplanetary communications) was opened and O was organized into the Solar Engine. Regular communication was established between the Earth and Mars on the mentioned ships.”
