The two-chart below demonstrate the number of spacecrafts launched by diverse national government from 1957 to 2007 with the purpose of each mission.
As can be seen from the graph, Russia is dominant in the number of spacecrafts, accounted for approximately half of the chart: 3484 satellites. Followed by the USA with 1760 launches. In contrast, India was by far the lowest with 48 spacecrafts. Other contributors such as China (111 launches), Canada (28 launches), Japan (114 launches), among others. The line graph provide a conprehensive overview of the purposes for which these spacecrafts were launched. It is obvious that over 25 percentages of launches were devoted to communications, making it the most common purposes. By comparision, palanetary exploration and weather observation accountes for just over 5 percentages of launches. Notably, surveilance satellites accounted for just under one fifth of launches and research purposes were around one tenth. The figure for manned space programs was very slow.
overall, the charts illustrate the varied range of missions organized by national governments and commercial entities
