This project was first revealed to the public during the Indo Defence Expo-2008 exhibition in Jakarta. [ 4 ] In 2008, optimistic hopes were that this rocket, known as SLV (Satellite Launch Vehicle) would first be launched in Indonesia in 2012, and if there were extra funds pursuant to the good economic situation of 2007–2008, possibly in 2010.
Orbital velocity may refer to the following: The orbital angular velocity; The orbital speed of a revolving body in a gravitational field. The velocity of particles due to wave motion, such as those in wind waves; The equivalent velocity of a bound electron needed to produce its orbital kinetic energy
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
In astrodynamics, the vis-viva equation is one of the equations that model the motion of orbiting bodies.It is the direct result of the principle of conservation of mechanical energy which applies when the only force acting on an object is its own weight which is the gravitational force determined by the product of the mass of the object and the strength of the surrounding gravitational field.
The Foreign Language Film Award Committee oversees the process and reviews all the submitted films. Following this, they vote via secret ballot to determine the five nominees for the award. The Indonesian submissions are selected by Persatuan Produser Film Indonesia (English: Indonesian Motion Picture Producers Association). [8]
The speed (or the magnitude of velocity) relative to the centre of mass is constant: [1]: 30 = = where: , is the gravitational constant, is the mass of both orbiting bodies (+), although in common practice, if the greater mass is significantly larger, the lesser mass is often neglected, with minimal change in the result.

A two-stage-to-orbit (TSTO) or two-stage rocket is a launch vehicle in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between a three-stage-to-orbit launcher and a hypothetical single-stage-to-orbit (SSTO) launcher.
