Content:  A third launch pad is under construction at Satish Dhawan Space Centre with the ability to support heavy lift launchers and human spaceflight while the second one is being augmented with similar systems to realise the mission on time. India's crewed orbital vehicle will have two uncrewed flights–at the end of 2020 and mid-2021—before actually taking humans onboard at the end of 2021. Indian astronauts will be dubbed "Vyomanauts" or "Gaganauts". Selected by the Indian Institute of Aerospace Medicine, a team of seven test pilots from the Indian Air Force are undergoing training in Russia per the memorandum of understanding with Glavkosmos, out of which 4 will be ready for India's first human space mission.
Title: Comparison of Asian national space programs
Content:   India's interest in space travel began in the early 1960s, when scientists launched a Nike-Apache rocket from TERLS, Kerala. Under Vikram Sarabhai, the program focused on the practical uses of space in increasing the standard of living by sending remote sensing and communications satellites into orbit. India's space launch vehicles are SLV, ASLV, PSLV, GSLV, SSLV, ULV, RLV, HLV and some Sounding Rockets such as Rohini. Some of them are retired and not in operation and some of them are under developmental progress. The first Indian to travel in space was Rakesh Sharma, who flew aboard Soyuz T-11, launched 2 April 
Title: Human spaceflight
Content:  Under the Indian Human Spaceflight Program, India was planning to send humans into space on its orbital vehicle Gaganyaan before August 2022, but it has been delayed to 2023, due to the COVID-19 pandemic. The Indian Space Research Organisation (ISRO) began work on this project in 2006. The initial objective is to carry a crew of two or three to low Earth orbit (LEO) for a 3-to-7-day flight in a spacecraft on a GSLV Mk III rocket and return them safely for a water landing at a predefined landing zone. On 15 August 2018, Indian Prime Minister Narendra Modi, declared India will independently send humans into space before the 75th anniversary of independence in 
Title: History of spaceflight
Content:  Indian Space Research Organisation, India's national space agency, maintains an active space program. It operates a small commercial launch service and launched a successful uncrewed lunar mission dubbed Chandrayaan-1 in October 2007. India has successfully launched an interplanetary mission, Mars Orbiter Mission, in 2013 which reached Mars in September 2014, hence becoming the first country in the world to do a Mars mission in its maiden attempt. On July 22, 2019, India sent Chandrayaan-2 to the Moon, whose Vikram lander crashed on the lunar south pole region on September 6.

The Government of India forayed into space exploration when scientists started to launch sounding rockets from Thumba Equatorial Rocket Launching Station (TERLS), Kerala. The establishment of the space agency lead to the development of small launch vehicles SLV-3 and ASLV, followed by larger PSLV and GSLV rockets in the 90s, which allowed India to shift larger payloads and undertake commercial launches for the international market. Private firms started to emerge later as subcontractors for various rocket and satellite components. Reforms liberalising the space sector and nondisclosure agreements came in the late 2010s, leading to the emergence of various private spaceflight companies. By 2019, India had launched more than 300 satellites for various foreign states. There were more than 40 startups in India in early 2021 in various stages of developing their own launch vehicles, designing satellites and other allied activities.
Title: Indian Human Spaceflight Programme
Content:  The Indian Human Spaceflight Programme (IHSP ) was initiated in 2007 by the Indian Space Research Organisation (ISRO) to develop the technology needed to launch crewed orbital spacecraft into low Earth orbit. The first uncrewed flight, named Gaganyaan 1, is scheduled to launch no earlier than June 2022 on a GSLV Mark III rocket. Before the Gaganyaan mission announcement in August 2018, human spaceflight was not a priority for ISRO, but it had been working on related technologies and it performed a Crew Module Atmospheric Re-entry Experiment and a Pad Abort Test for the mission. In December 2018, the government approved further ₹ 100 billion (US$1.5 billion) for a 7-days crewed flight of 2–3 astronauts. If completed in meantime, India will become the fourth nation to conduct independent human spaceflight after the Soviet Union/Russia, United States and China. After conducting the first crewed spaceflights, the agency intends to start a space station programme, crewed lunar landings, and crewed interplanetary missions in the long term.
Title: Space industry of India
Content:  India's interest in space travel began in the early 1960s, when scientists launched a Nike-Apache rocket from TERLS, Kerala. The Indian National Committee for Space Research was subsequently set up, which later became the Indian Space Research Organisation (ISRO) functioning under a new independent Department of Space in the 1970s under the Prime Minister of India. ISRO joined the Interkosmos program to launch its first satellite, Aryabhata, from the former Soviet Union in 1975. SLV-3, a locally developed space rocket, was introduced in 1979, enabling India to undertake orbital launches. Experience gained from SLV-3 was used to develop an Augmented Satellite Launch Vehicle to develop technologies for launching satellites in geostationary orbit, but this ended up having very limited success and was eventually discontinued. However, the study of a homegrown medium-lift launch vehicle went on, which lead to the realisation of the Polar Satellite Launch Vehicle (PSLV).

An example is Czechoslovak Vladimír Remek, the first cosmonaut from a country other than the Soviet Union or the United States, who flew to space in 1978 on a Soyuz-U rocket. Rakesh Sharma became the first Indian citizen to travel to space. He was launched aboard Soyuz T-11, on 2 April 1984. On 23 July 1980, Pham Tuan of Vietnam became the first Asian in space when he flew aboard Soyuz 37. Also in 1980, Cuban Arnaldo Tamayo Méndez became the first person of Hispanic and black African descent to fly in space, and in 1983, Guion

A space capsule recovery experiment in 2014 and a pad abort test in 2018 were followed by PM Modi's announcement on Independence Day address 15 August 2018 that India will send astronauts into space by 2022 on the new Gaganyaan spacecraft. Till date, ISRO has developed most of the technologies needed such as crew module and crew escape system, space food and life support systems. The project would cost less than ₹100 billion and would include sending 2 or 3 Indians to space, 300 - 400 km above in a spacecraft for at least seven days using a GSLV Mk-III launch vehicle.

In August – September 2013, clashes between Hindus and Muslims in Muzaffarnagar, Uttar Pradesh, resulted in at least 62 deaths, injured 93, and left more than 50,000 displaced. In November 2013, India launched its first interplanetary mission, the Mars Orbiter Mission, popularly known as Mangalyaan, to Mars and, was successful, so ISRO on 24 September 2014, became the fourth space agency to reach Mars, after the Soviet space program, NASA, and the European Space Agency. ISRO also became the first space agency and India the first country to reach Mars on its maiden attempt.
