Contemporary scientific concepts about the origin of the earth and the planets of our solar system are discussed along with the satellites of the planets, the minor planets, meteoric objectives, bolides, and meteorites. Why spacecraft are used to study the sun, its accompanying planets, and their satellites is explained. Data about the surface and atmosphere of Mars and Venus and the seasons, days, and climate of these planets are included. Data are given for the contemporary cosmodromes and spacecraft centers, spaceflight devices, and the chemical, nuclear, and electrical rocket motors. Selection of interplanetary trajectories and the peculiarities and conditions for flight to the near and distant celestial objects of our solar system both by automatic unmanned devices and by manned spaceships are discussed.
