Aerospace In India 

















India began its space program in 1963 under the Department of Atomic Energy and with the establishment of The Space Commission and Department of Space in 1972 it was formalized. India has made steady progress in the development of launch vehicles and satellites. The first Indian satellite was Aryabhata, which was launched by a Soviet rocket on 19th April 1975. With the successful launch of the SLV-3 on 18th July 1980 when a 35kg satellite called Rohini was placed in LEO, India became only the seventh nation in the world to achieve space orbit capability.

The primary objective of the Indian Space Program is to achieve self-reliance in space technology and develop application driven programs to meet the national needs. Space technology in India is primarily geared towards improving telecommunications, meteorological forecasting, providing advanced natural disaster warning, distance education and remote sensing for agriculture, soil, mineral and water resources management.

India's first operational Earth Observation satellite IRS-1A, a 850 kg satellite was launched into a 900 Km polar orbit on 17th March 1988 by a Soviet rocket. In 1997, India used its own rocket PSLV to place IRS-1D into polar orbit. With the development of PSLV, India has the capability to place upto 1,200 kg satellites into polar orbit. The Indian Remote Sensing Satellite (IRS) system has the largest constellation of commercial earth observation providing data in a variety of spatial and spectral resolutions.

India's first operational telecommunications satellite was INSAT-1A, which was launched by a NASA Delta rocket on 10th April 1982. Since then, India relied on European Space Agency's Ariane rockets to launch its INSAT series satellites into geostationary orbit.

On April 18, 2001, India blasted itself into the elite space club of heavy satellite launchers with the successful test-flight of GSLV-D1. The successful launch of India's first educational communication satellite "EDUSAT" by GSLV-F01 on September 20, 2004 heralds the operational reliability of the heavy lifter to Geostationary orbits.

Antrix, the commercial arm of ISRO is responsible for marketing to international customers and PSLV launcher has so far placed two foreign payloads, one for Italy and one for Israel successfully
