SOLAR SYSTEM

Detailed explanation-1: -A rocket is simply a vehicle designed to overcome Earth’s gravity, escape Earth’s atmosphere and carry a payload into space. The payload could be deployed to orbit the earth, or for interplanetary travel and space exploration.

Detailed explanation-2: -A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction.

Detailed explanation-3: -A good rule of thumb is that 90% of a rocket’s weight is fuel.

Detailed explanation-4: -Orbital launch The speed needed to maintain an orbit near the Earth’s surface corresponds to a sideways speed of about 7.8 km/s (17, 400 mph), an energy of about 30MJ/kg. This is several times the energy per kg of practical rocket propellant mixes.

Detailed explanation-5: -Rockets deliver satellites to space where they can begin to do their important work. Without rockets, we wouldn’t be able to use our cell phones, watch a lot of our favorite television shows, find out the weather forecast, navigate with Global Positioning System (GPS), or explore our solar system-just to name a few.

Detailed explanation-6: -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-7: -Like most engines, rockets burn fuel. Most rocket engines turn the fuel into hot gas. The engine pushes the gas out its back. The gas makes the rocket move forward.
