== History ==
=== Formative years ===
Modern space research in India can be traced to the 1920s, when scientist [[Sisir Kumar Mitra|S. K. Mitra]] conducted a series of experiments sounding the [[ionosphere]] through ground-based radio in [[Kolkata]].{{sfn|Daniel|1992|pp=486}} Later, Indian scientists like [[C. V. Raman]] and [[Meghnad Saha]] contributed to scientific principles applicable in space sciences.{{sfn|Daniel|1992|pp=486}} After 1945, important developments were made in coordinated space research in India{{sfn|Daniel|1992|pp=486}} by two scientists: Vikram Sarabhai, founder of the [[Physical Research Laboratory]] at [[Ahmedabad]], and [[Homi J. Bhabha|Homi Bhabha]], who established the [[Tata Institute of Fundamental Research]] in 1945.{{sfn|Daniel|1992|pp=486}} Initial experiments in space sciences included the study of [[Cosmic ray|cosmic radiation]], high-altitude and airborne testing, deep underground experimentation at the [[Particle experiments at Kolar Gold Fields|Kolar mines]]—one of the deepest mining sites in the world—and studies of the [[Atmosphere of Earth|upper atmosphere]].{{sfn|Daniel|1992|pp=487}} These studies were done at research laboratories, universities, and independent locations.{{sfn|Daniel|1992|pp=487}}{{sfn|Daniel|1992|pp=488}}

In 1950, the Department of Atomic Energy (DAE) was founded with Bhabha as its [[Secretary to the Government of India|secretary]].{{sfn|Daniel|1992|pp=488}} It provided funding for space research throughout India.{{sfn|Daniel|1992|pp=489}} During this time, tests continued on aspects of [[meteorology]] and the [[Earth's magnetic field]], a topic that had been studied in India since the establishment of the [[Colaba Observatory]] in 1823. In 1954, the [[Aryabhatta Research Institute of Observational Sciences]] (ARIES) was established in the foothills of the Himalayas.{{sfn|Daniel|1992|pp=488}} The Rangpur Observatory was set up in 1957 at [[Osmania University]], [[Hyderabad]]. Space research was further encouraged by the government of India.{{sfn|Daniel|1992|pp=489}} In 1957, the Soviet Union launched [[Sputnik 1]] and opened up possibilities for the rest of the world to conduct a space launch.{{sfn|Daniel|1992|pp=489}}

INCOSPAR was set up in 1962 by the Prime Minister [[Jawaharlal Nehru]] on the suggestion of Dr. Vikram Sarabhai.{{sfn|Sadeh|2013|pp=303-}} Initially there was no dedicated ministry for the space programme and all activities of INCOSPAR relating to space technology continued to function within the DAE.<ref name="DAE">{{Cite web |url=http://www.dae.nic.in/?q=node%2F394 |title=Government of India Atomic Energy Commission &#124; Department of Atomic Energy |access-date=21 September 2019 |archive-url=https://web.archive.org/web/20190829222918/http://dae.nic.in/?q=node%2F394 |archive-date=29 August 2019 |url-status=dead}}</ref>{{sfn|Bhargava|Chakrabarti|2003|pp=39}} [[Indian Ordnance Factories Service|IOFS]] officers were drawn from the [[Directorate of Ordnance (Coordination & Services)|Indian Ordnance Factories]] to harness their knowledge of propellants and advanced light materials used to build rockets.<ref>{{cite web |url=https://www.thehitavada.com/Encyc/2021/9/19/-Success-is-yours-failure-is-mine-makes-one-a-great-leader-Mujumdar.html |title='Success is yours, failure is mine' makes one a great leader: Mujumdar |access-date=6 December 2022 |archive-date=6 December 2022 |archive-url=https://web.archive.org/web/20221206214943/https://www.thehitavada.com/Encyc/2021/9/19/-Success-is-yours-failure-is-mine-makes-one-a-great-leader-Mujumdar.html |url-status=live }}</ref> [[H.

=== 1970's and 1980's ===
Under the government of [[Indira Gandhi]], INCOSPAR was superseded by ISRO. Later in 1972, a space commission and Department of Space (DoS) were set up to oversee space technology development in India specifically. ISRO was brought under DoS, institutionalising space research in India and forging the Indian space programme into its existing form.{{sfn|Bhargava|Chakrabarti|2003|pp=39}}<ref name="DOSHQ" /> India joined the Soviet Interkosmos programme for space cooperation<ref name="Sheehan">{{cite book |last=Sheehan |first=Michael |title=The international politics of space |year=2007 |publisher=Routledge |isbn=978-0-415-39917-3 |url=https://books.google.com/books?id=V-Z0kfqPHy8C |location=London |pages=59–61 |access-date=14 March 2021 |archive-date=13 April 2021 |archive-url=https://web.archive.org/web/20210413211452/https://books.google.com/books?id=V-Z0kfqPHy8C |url-status=live}}</ref> and got its first satellite Aryabhata in orbit through a Soviet rocket.<ref name="Aryabhatta" />

Efforts to develop an orbital launch vehicle began after mastering sounding rocket technology. The concept was to develop a launcher capable of providing sufficient velocity for a mass of {{cvt|35|kg}} to enter [[low Earth orbit]]. It took 7 years for ISRO to develop [[Satellite Launch Vehicle]] capable of putting {{cvt|40|kg}} into a {{convert|400|km|mi|adj=on}} orbit. An SLV Launch Pad, [[ground station]]s, tracking networks, radars and other communications were set up for a launch campaign. The SLV's first launch in 1979 carried a [[Rohini (satellite)|Rohini technology payload]] but could not inject the satellite into its desired orbit. It was followed by a successful launch in 1980 carrying a Rohini Series-I satellite, making India the seventh country to reach Earth's orbit after the USSR, the US, France, the [[Prospero (spacecraft)|UK]], China and Japan. RS-1 was the third Indian satellite to reach orbit as [[Bhaskara (satellites)|Bhaskara]] had been launched from the USSR in 1979. Efforts to develop a [[medium-lift launch vehicle]] capable of putting {{convert|600|kg|lb|adj=on}} class spacecrafts into {{convert|1000|km|mi|adj=on}} [[Sun-synchronous orbit]] had already begun in 1978.<ref>{{cite news |url=https://books.google.com/books?id=IbbMj56ht8sC&pg=PA215 |title=Indian ambitions in space go sky-high |date=22 January 1981 |publisher=New Scientist |page=215 |access-date=14 March 2021 |archive-date=13 April 2021 |archive-url=https://web.archive.org/web/20210413211511/https://books.google.com/books?id=IbbMj56ht8sC&pg=PA215 |url-status=live}}</ref> They would later lead to the development of the [[Polar Satellite Launch Vehicle|Polar Satellite Launch Vehicle (PSLV)]].<ref name="SLVFlipbook">{{cite web |url=https://www.isro.gov.in/sites/default/files/flipping_book/58-SI-Jul-Sep-05/files/assets/common/downloads/publication.pdf |title=First Successful Launch of SLV-3 – Silver Jubilee |publisher=ISRO |page=17 |date=July–September 2005 |access-date=15 March 2021 |archive-date=12 November 2020 |archive-url=https://web.archive.org/web/20201112000426/https://www.isro.gov.in/sites/default/files/flipping_book/58-SI-Jul-Sep-05/files/assets/common/downloads/publication.pdf |url-status=live}}</ref> The [[SLV-3]] later had two more launches before discontinuation in 1983.<ref name=slv>{{cite web |url=http://www.isro.gov.in/launchers/slv |title=SLV |publisher=isro.gov.in |access-date=15 March 2021 |archive-date=29 May 2017 |archive-url=https://web.archive.org/web/20170529133357/http://www.isro.gov.in/launchers/slv |url-status=live}}</ref> ISRO's [[Liquid Propulsion Systems Centre]] (LPSC) was set up in 1985 and started working on a more powerful engine, [[Vikas (rocket engine)|Vikas]], based upon the French [[Viking (rocket engine)|Viking]].<ref>{{cite book |last1=Sutton |first1=George Paul |title=History of Liquid Propellant Rocket Engines |date=2006 |publisher=AIAA |isbn=978-1-56347-649-5 |page=799 |url=https://books.google.com/books?id=s1C9Oo2I4VYC&pg=PA799 |language=en |access-date=14 March 2021 |archive-date=13 April 2021 |archive-url=https://web.archive.org/web/20210413211426/https://books.google.com/books?id=s1C9Oo2I4VYC&pg=PA799 |url-status=live}}</ref> Two years later, facilities to test liquid-fuelled rocket engines were established and development and testing of various rocket engines [[Thrusters (spacecraft)|thrusters]] began.<ref name="lpsctimeline">{{Cite web |title=Timeline of LPSC |url=https://www.lpsc.gov.in/timeline.html |work=Liquid Propulsion Systems Centre |access-date=15 March 2021 |archive-date=9 March 2021 |archive-url=https://web.archive.org/web/20210309084932/https://www.lpsc.gov.in/timeline.html |url-status=live}}</ref>

At the same time, another solid-fuelled rocket, the [[Augmented Satellite Launch Vehicle|Augmented Satellite Launch Vehicle (ASLV)]], whose design was based upon SLV-3 was being developed, with technologies to launch satellites into [[geostationary orbit]] (GTO).

=== 1990s ===
The arrival of the PSLV in 1990s was a major boost for the Indian space programme. With the exception of its first flight in 1994 and two partial failures later, the PSLV had a streak of more than 50 successful flights. The PSLV enabled India to launch all of its [[low Earth orbit]] satellites, small payloads to GTO and hundreds of [[List of foreign satellites launched by India|foreign satellites]].<ref name="gsp-pslv-1">{{cite web |title=PSLV (1) |url=http://space.skyrocket.de/doc_lau_det/pslv_1.htm |publisher=Gunter's Space Page |access-date=16 March 2021 |archive-date=5 December 2020 |archive-url=https://web.archive.org/web/20201205170455/https://space.skyrocket.de/doc_lau_det/pslv_1.htm |url-status=live}}</ref> Along with the PSLV flights, development of a new rocket, a [[Geosynchronous Satellite Launch Vehicle]] (GSLV) was going on.
