Nasa updating technology for space travel

At the velocity of the Earth (30,000 meters per second), the Moon, for example, also circles the sun, as will our future space station (both as satellites of the Earth).

If the space vehicle is brought in this fashion into the practical effective range of gravity of the destination celestial body, then the possibility exists either to orbit the body in a free orbit as a satellite as often as desired or to land on it.

Landing can, if the celestial body has an atmosphere similar to that of the Earth, occur in the same fashion as previously discussed for the Earth (Hohmann's landing manoeuver, Figures 44 and 45).
