Described herein are systems, methods, media, and devices for generating a satellite program for contacting satellites. In some embodiments, data including one or more targets for accessing a satellite constellation is obtained. Based on the data, a set of representations may be generated and candidate satellite constellation access programs may be determined based on the set of representations. For each program, a first score may be computed for each target to obtain a first set of scores, and a second score may be computed for each first score of the first set of scores to obtain a second set of scores. A satellite constellation access program may be selected from the candidate satellite access programs based on the second set of second scores.
