The Indian Space Research Organisation (ISRO) was established in 1969 to advance India's space technology and research. Some of ISRO's key accomplishments include launching India's first satellite, Aryabhata, in 1975, launching the Rohini satellite which was the first with an Indian-made launch vehicle in 1980, launching an unmanned mission to the moon called Chandrayaan in 2008 to map the lunar surface, and launching the Mars Orbiter Mission in 2014, making India the first nation to reach Mars on its first attempt. ISRO has also launched over 100 satellites using its launch vehicles, including launching 31 satellites at once, 28 of which belonged to other countries.
