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 understanding that can be developed in a variety of ways. Comparing sounds is the easiest task for developing phonemic awareness. Sound sorts can be introduced very early on and develop strategically throughout primary learning. An ability to sort sounds is essential for early reading because sound manipulation is a stepping stone to word study and decoding ability. For some students a direct instructional approach is not necessary in the development of sound study and sorting. Other children who have had less exposure or lack the understanding of sounds and their manipulability may need further instruction to develop their ability. Teachers
