Somanath stated that the long-term goal is for all Indian space actors—both governmental and non-governmental—to accomplish debris-free space missions by 2030. Since the launch of Aryabhata in 1975,
5624-420: Was prompted to develop its own satellite navigation system IRNSS (now NaVIC i.e. Navigation with Indian Constellation) which it is now expanding further. In 2003, Prime Minister Atal Bihari Vajpayee urged scientists to develop technologies to land humans on the Moon and programmes for lunar, planetary and crewed missions were started. ISRO launched Chandrayaan-1 in 2008, purportedly the first probe to verify
5700-704: Was set up in 1985 and started working on a more powerful engine, Vikas , based upon the French Viking . Two years later, facilities to test liquid-fuelled rocket engines were established and development and testing of various rocket engines thrusters began. At the same time, another solid-fuelled rocket, the Augmented Satellite Launch Vehicle (ASLV) , whose design was based upon SLV-3 was being developed, with technologies to launch satellites into geostationary orbit (GTO). The ASLV had limited success and multiple launch failures; it
5776-509: Was soon discontinued. Alongside these developments, communication satellite technologies for the Indian National Satellite System and the Indian Remote Sensing Programme for earth observation satellites were developed and launches from overseas were initiated. The number of satellites eventually grew and the systems were established as among the largest satellite constellations in the world, with multi-band communication, radar imaging, optical imaging and meteorological satellites.
