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
Selection sort finds both the minimum and maximum values in the list in every pass. This reduces the number of scans of the list by a factor of 2, eliminating some loop overhead but not actually decreasing the number of comparisons or swaps. Note, however, that cocktail sort more often refers to a bidirectional variant of bubble sort. Sometimes this is double selection sort. Selection sort can be implemented as a stable sort. If, rather than swapping in step 2, the minimum value is inserted into the first position (that is, all intervening items moved down), the algorithm is stable. However, this
