A rocket (from Italian: “rocchetto”) is a missile, spacecraft, aircraft, or other vehicles that obtains thrust from a rocket engine. There are many parts that make up a rocket. For design and analysis, engineers group parts which have the same function into systems. There are four major systems in a full-scale rocket; the structural system, the payload system, the guidance system, and the propulsion system.

The payload system of a rocket depends on the rocket’s mission. The earliest payloads on rockets were fireworks for celebrating holidays. Following World War II, many countries developed guided ballistic missiles armed with nuclear warheads for payloads. The same rockets were modified to launch satellites with a wide range of missions; communications, weather monitoring, spying, planetary exploration, and observatories, like the Hubble Space Telescope. Special rockets were developed to launch people into earth orbit and onto the surface of the Moon. read more

Indonesia needs satellites because it consists of several islands and it has diverse geographical contours, where it will be very difficult for a terrestrial communication system to cover the entire territory. Satellites can overcome things that can become obstacles to terrestrial telecommunication systems whether it is time, distance or content complexity. With satellites, remote areas can easily have the same communication system as those in cities and can connect with other areas more quickly.
