                                                 OR

                                     Launch vehicle

Just as an instrument is needed to move an object from one place to another, in order to send the satellite into the space, a vehicle is needed that leaves the satellite in space is called Launch Vehical.
                                                       or
Launch vehicle, in spaceflight a rocket-powered vehicle used to transport a spacecraft beyond EARTH’s atmosphere, either into orbit around Earth or to some other destination in outer space .

 HISTORY:

Sputnik I.

History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a beach ball (58 cm.or 22.8 inches in diameter), weighed only 83.6 kg. or 183.9 pounds, and took about 98 minutes to orbit the Earth on its elliptical path.

World first launch vehical;

 " the Sputnik 11A59 rocket"

• First Stage: Block B, V, G, D (four strap-on boosters)
  • Gross mass: 43.0 tons
  • Empty mass: 3.400 tons
  • Thrust (vac): 4 × 99,000 kgf = 396 Mgf (3.89 MN)
  • Burn time: 120 s (2 min)
  • Diameter: 2.68 metres (8.8 ft)
  • Span: 2.68 metres (8.8 ft)
  • Length: 19.2 metres (63 ft) (without nozzles)
• Second Stage: Block A (core stage)
  • Gross mass: 94.0 tons
  • Empty mass: 7.495 tons
  • Thrust (vac): 99,000 kgf (970 kN)
  • Burn time: 310 s (5 min 10 s)
  • Isp(sl): 241 s (2,360 N·s/kg)
  • Diameter: 2.95 metres (9.7 ft)
  • Span: 2.95 metres (9.7 ft)
  • Length: 28 metres (92 ft)
• Total mass: 267 tons (534,000 lb)
• Total span: 10.303 metres (33.80 ft)
• leo payload: 500 kg
• Total liftoff thrust: 3.89 MN

Clasiffication acording to Low EARTH orbit: 

.Small-lift launch vehicle: < 2,000 kilograms (4,400 lb) - e.g. Vega

.Medium-lift launch vehicle: 2,000 to 20,000 kilograms (4,400 to 44,100 lb) - e.g. Soyuz ST

.Heavy-lift launch vehicle: > 20,000 to 50,000 kilograms (44,000 to 110,000 lb) - e.g. Ariane 5

.Super-heavy lift vehicle: > 50,000 kilograms (110,000 lb) - e.g. Saturn V 

Sounding rockets are similar to small-lift launch vehicles, however they are usually even smaller and do not place payloads into orbit. A modified SS-520 sounding rocket was used to place a 4-kilogram payload (TRICOM-1R) into orbit in 2018.
