india's first satellite aryabhatta was launched by
Aryabhata (satellite) It was launched by India on 19 April 1975[1] from Kapustin Yar, a Russian rocket launch and development site in Astrakhan Oblast using a Kosmos-3M launch vehicle. It was built by the Indian Space Research Organisation (ISRO) to gain experience in building and operating a satellite in space.[5] The launch came from an agreement between India and the Soviet Union directed by UR Rao and signed in 1972. It allowed the USSR to use Indian ports for tracking ships and launching vessels in return for launching Indian satellites.[6].Aryabhatta is the first indian man made (artificial ) satellite.
Himalayas Lifted by the subduction of the Indian tectonic plate under the Eurasian Plate, the Himalayan mountain range runs west-northwest to east-southeast in an arc 2,400 kilometres (1,500 mi) long.[2] Its western anchor, Nanga Parbat, lies just south of the northernmost bend of Indus river. Its eastern anchor, Namcha Barwa, is just west of the great bend of the Yarlung Tsangpo River (upper stream of the Brahmaputra River). The Himalayan range is bordered on the northwest by the Karakoram and the Hindu Kush ranges, to the north, the chain is separated from the Tibetan Plateau by a 50–60 kilometres (31–37 mi) wide tectonic valley called the Indus-Tsangpo Suture.[3] Towards the south the arc of the Himalaya is ringed by the very low Indo-Gangetic Plain.[4] The range varies in width from 350 kilometres (220 mi) in the west (Pakistan) to 150 kilometres (93 mi) in the east (Arunachal Pradesh).[5] The Himalayas are distinct from the other great ranges of central Asia, although sometimes the term Himalaya (or Greater Himalaya) is loosely used to include the Karakoram and some of the other ranges.
