Apogee kick motor possible. The mass of most geostationary satellites at the beginning of its operational life in geostationary orbit is roughly half that when it separated from its vehicle in geostationary transfer orbit, with the other half having been fuel expended in the apogee kick maneuver. Apogee kick motor An apogee kick motor (AKM) refers to a rocket motor that is regularly employed on artificial satellites to provide the final impulse to change the trajectory from the transfer orbit into its final (most commonly circular) orbit. For a satellite launched from the Earth, the rocket firing is done at the highest point
Word sort be introduced at a very early stage and develop with a child’s individual ability. Sorting pictures or oral vocabulary is a manipulation of sounds, and this manipulation increases awareness. A simple introductory sort is by initial sound and this can develop to ending sound, vowel sounds, and word families sorts. The root of importance is student motivation and involvement in the sort.
