SOLAR SYSTEM

Detailed explanation-1: -We launch satellites and spacecraft into space by putting them on rockets carrying tons of propellants. The propellants give the rocket enough energy to boost away from Earth’s surface.

Detailed explanation-2: -When describing the action of forces, one must account for both the magnitude and the direction. In flight, a rocket is subjected to four forces; weight, thrust, and the aerodynamic forces, lift and drag.

Detailed explanation-3: -There are four major systems in a full scale rocket; the structural system, the payload system, the guidance system, and the propulsion system.

Detailed explanation-4: -Rockets, also called launch vehicles, play an important role in our lives. Rockets deliver satellites to space where they can begin to do their important work.

Detailed explanation-5: -The Shuttle has the most reliable launch record of any rocket now in operation. Since 1981, it has boosted more than 1.36 million kilograms (3 million pounds) of cargo into orbit. More than than 600 crew members have flown on its missions.

Detailed explanation-6: -A spacecraft is a vehicle that is designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
