To achieve low CO2 emission during 16 orbits per day around the earth by making a space flight with no CO2 emission flourish so as to solve a problem that an existing aircraft receives extremely-high air resistance during an atmospheric flight and emits an enormous amount of CO2.

A mercury gravity turbine is driven. A power rate in atmospheric pressure and at an equal speed and an equal volume is set, for example, as mercury power equivalent to approximate 23,000 times of that of an existing steam turbine. In heat production, air heated by solar light is compressed by a large number of heat pumps, and heat is recovered by heating and compressing the air heated by solar light. Superheated steam is produced by heating, and compressed air is produced in a cold state. The superheated steam and the compressed air are separately preserved, and used for rotation outputs of a plurality of turbines. The existing aircraft driven as a solar heat gravity helicopter (39C) with a combined engine jetting section (78B) by aiming at jet propulsion utilizing the power rate equivalent to approximate 23,000 times of that of the existing steam turbine reaches an outer space by the theoretically best rocket jetting from the proximity of a maximum flight altitude. Cost for arrival in the outer space is set at 1/100 or lower so as to aim at a rocket with a speed which allows escape from the solar system. Thus, the space flight with no air resistance flourishes, and a day trip to any place on the earth and the space flight flourish.
