The Indian Space Research Organisation is the national space agency of India. It operates as the primary research and development arm of the Department of Space (DoS), which is directly overseen by the Prime Minister of India while the Chairman of ISRO also acts as the executive of DoS. ISRO is primarily responsible for performing tasks related to space-based operations, space exploration, international space cooperation and the development of related technologies. ISRO is one of the six government space agencies in the world that possesses full launch capabilities, can deploy cryogenic engines, can launch extraterrestrial missions and operate a large fleet of artificial satellites. ISRO is one of the four government space agencies to have soft landing (uncrewed) capabilities.

INSAT-2B was the second satellite in the INSAT 2 Series that was successfully launched for telecommunication and meteorological observation. This India satellite was launched on 23 July 1993 from Kourou, French Guiana and Ariane-4 being its launch vehicle. INSAT-2B is placed in the geostationary orbit at a longitude of 93.5 degree East. The satellites also carries a search and rescue(SAR) transponder, a data relay transponder and also high resolution radiometer. This radiometer has a resolution of 2 km (1.2 mi) in the normal visible band and of 8 km (5.0 mi) in the thermal infra red band.

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite. The satellite will be the first radar imaging satellite to use dual frequencies. It will be used for remote sensing, to observe and understand natural processes on Earth. For example, its left-facing instruments will study the Antarctic cryosphere. With a total cost estimated at US$1.5 billion, NISAR is likely to be the world's most expensive Earth-imaging satellite.
