As of 2015, India has launched six major types of satellites into space: communication, Earth observation, navigation, experimental, small and student satellites. Scientific spacecrafts were also sent to space primarily for research purposes.
The agency that officially oversees India's space program is the Indian Space Research Organization, a project of the government's Department of Space. Since its inception, ISRO has launched more than 70 artificial satellites. These man-made objects have a variety of applications, including weather forecasting, news gathering, television signal transmission, global positional charting, Earth imaging, remote sensing, payload development and recovery technology. In 2014, India became the fourth nation to successfully launch a satellite into Mars orbit with Mangalyaan.
