The Indian Human Spaceflight program (or the Gaganyaan program) is an ongoing programme by the Indian Space Research Organisation (ISRO) to develop the technology needed to launch crewed orbital spacecraft into low Earth orbit. [4] Three uncrewed flights, named Gaganyaan-1, Gaganyaan-2 and Gaganyaan-3 are scheduled to launch in 2024, followed by crewed flight in 2024 on an HLVM3 rocket. [3] [2] [5] [6] [7]
Before the Gaganyaan mission announcement in August 2018, human spaceflight was not a priority for ISRO, but it had been working on related technologies since 2007, [8] and it performed a Crew Module Atmospheric Re-entry Experiment [9] and a Pad Abort Test for the mission. [10] [11] In December 2018, the government approved a further ₹100 billion (US$1.5 billion) for a 7-days crewed flight of 2–3 astronauts. [12] [13] [14] [15]
If completed successfully, 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. [16] [17]
On August 9, 2007, the then Chairman of the ISRO, G. Madhavan Nair, indicated the agency was "seriously considering" the creation of the Human Spaceflight Programme. He further indicated that within a year, ISRO would report on its development of new space capsule technologies. [18] Development of a fully autonomous orbital vehicle to carry a two-member crew into low Earth orbit (LEO) began a few months after that when the government allocated ₹95 crore (US$11.4 million) for pre-project initiatives for 2007 through 2008. A crewed orbital spaceflight would require about ₹12,400 crore (US$1.5 billion) and a period of seven years of development. The Planning Commission estimated that a budget of ₹5,000 crore (US$599.1 million) was required for initial work during 2007–2012 for the crewed spaceflight. [8] [19] In February 2009, the Government of India authorized the human space flight programme, [20] but fell short of fully funding it or creating the programme.
The trials for crewed space missions began in 2007 with the 600 kg Space Capsule Recovery Experiment (SRE), launched using the Polar Satellite Launch Vehicle (PSLV) rocket, and safely returned to Earth 12 days later. This was followed by the Crew Module Atmospheric Re-entry Experiment and the Pad Abort Test in 2018. This enables India to develop heat-resistant materials, technology, and procedures necessary for human space travel.
As per memorandum of understanding (MoU), Defence Research and Development Organisation (DRDO) will provide support for Human Space Mission with critical human-centric systems and technologies like space-grade food, crew healthcare, radiation measurement and protection, parachutes for the safe recovery of the crew module, fire suppression systems, etc. [21] Defence Food Research Laboratory (DFRL) has worked on the space food for the crew and has been conducting trials on a G-suit for astronauts as well. [22] [23] A prototype called 'Advanced Crew Escape Suit' weighing 13 kg and built by Sure Safety (India) Private Limited has been tested and performance verified. [24] [25] [26] [27] While the crew module is designed to carry a total of 3 passengers, the maiden crewed mission may only have one or two crews on board. [28]
Having shown success in all preliminary tests, [29] the decisive push for the creation of the Human Spaceflight Programme took place in 2017, [30] and it was accepted and formally announced by the Prime Minister on August 15, 2018. [31] The funding is approximately Rs 10,000 crore. The testing phase was expected to begin in December 2020, and the first crewed mission was to be undertaken in December 2021. [32] However, on June 11, 2020, it was announced that the overall schedule for the Gaganyaan launches had been postponed due to the impact of the COVID-19 pandemic in India, in turn revising the timetable for the HSP. [33] As of December 2022, the first uncrewed test flight is scheduled to launch no earlier than mid-2024, [6] with the uncrewed second and crewed third flights to follow afterward. [5] As per ISRO, the initial review process is complete for food, potable water, emergency first aid kits, and health monitoring systems for the Gaganyaan mission until March 16, 2021.[ citation needed ] ISRO and the CNES joint working group on the Human Spaceflight Programme are collaborating on space medicine for Gaganyaan project. [34]

The first phase of this programme is to develop and fly the 3.7-ton spacecraft called Gaganyaan with the capacity to carry a 3-member crew in low Earth orbit and safely return to Earth after a mission duration of a few orbits to two days. [36] The extendable version of the spaceship will allow flights up to seven days, rendezvous and docking capability. Before the flight of the Gaganyaan module, Group Captain Shubhanshu Shukla would fly on the Axiom-4 Mission to the International Space Station. [39] [40]
In the next phase, enhancements will lead to the development of a small habitat, allowing spaceflight durations of 30–40 days at once. Further advances based on experience will subsequently lead to development of a space station. [41]
On October 7, 2016, Vikram Sarabhai Space Center Director K. Sivan stated that ISRO was gearing up to conduct a critical 'crew bailout test' called the ISRO Pad Abort Test to see how fast and effectively the crew module could be released safely in the event of an emergency. The tests were conducted successfully on July 5, 2018, at Satish Dhawan Space Centre, Sriharikota. This was the first of a series of tests to qualify a crew escape system technology. [42] [43] Parachute tests were scheduled before the end of 2019, and multiple in-flight abort tests were planned starting mid-2020. [44] [ needs update ]
India will not use any animals for life support system testing but robots resembling humans will be used. [45] [46] ISRO is targeting more than 99.8% reliability for its crew escape system. [47]
ISRO plans to launch its crewed orbiter Gaganyaan atop a Launch Vehicle Mark 3 (LVM3). [7] About 16 minutes after lift-off, the rocket will inject the orbital vehicle into an orbit 300 to km above Earth. The capsule would return for a splashdown in the Arabian Sea near the Gujarat coastline. [48] As of May 2019, the design of the crew module was complete. [49] The spacecraft will be flown twice uncrewed for validation before conducting actual human spaceflight. [50] [51] [52] As of January 2020, the crew module was due to undergo testing in the wind tunnel facility of the Council of Scientific and Industrial Research (CSIR) at the National Aerospace Laboratories (NAL). [53] The spacecraft will carry one crew in its maiden crewed mission to an orbit of 400 km (250 mi). [28]
The first uncrewed flight will involve the launch of a 5,000 kg (11,000 lb) module which, after orbiting will re-enter the atmosphere and decelerate at an altitude of 7 km (4.3 mi) before splashing down. [54]
India's maiden crewed mission is expected to take off from the Satish Dhawan Space Centre Second Launch Pad. In November 2019, ISRO released tenders for the pad's augmentation. [55] [56] [57] [58] [59] A third launch pad in Sriharikota has been proposed for India's future launch vehicles and crewed missions. [60] Systems for crew ingress and egress, an access platform, recovery setup for emergencies during the flight’s ascent phase, module preparation facility for assembly and testing will be built. All the facilities will be connected to an upcoming Gaganyaan control facility which will be built nearby and facilitate communication and monitor the crew capsule during flight. [61]
Human-rating allows the system to be capable of safely transporting humans. ISRO will be building and launching 3 missions to validate the human rating of the LVM3. [3] [62] Existing launch facilities will be upgraded to enable them to carry out launches under the Indian Human Spaceflight campaign. [63] [64]
ISRO has been modifying propulsion modules of various stages of the rocket for human rating. Theoretical parameters for human rating were expected to be achieved by August or September 2020 to be followed by simulations and three test launches. [65] [ needs update ]
ISRO has successfully conducted a pad abort test to validate its launch escape system for fast and effective crew extraction in the event of an emergency. The tests were conducted successfully on July 5, 2018, at Satish Dhawan Space Centre, Sriharikota. This was the first of a series of tests to qualify a crew escape system technology. [42] [43] Work on parachute enlargement is also ongoing. [62] [66] Parachute tests are scheduled before the end of 2019, and multiple in-flight abort tests are planned starting mid-2020, using a liquid-fueled test vehicle. [44] [67] [ needs update ]
A new test vehicle was designed in early 2020 for the validation of the crew escape system. The vehicle was built for in-flight crew escape of crew and possesses propulsion on top of the module to pull the module away to a safe distance. [65]
ISRO is working on developing an indigenous mechanism to certify its spacecraft that will take humans to space. [68]
The spacecraft is expected to communicate with ISTRAC and other partner antennaes.For the Initial test flights, it has been planned that Two terminal ships are to be placed in both the Pacific Ocean and the Atlantic Ocean for communication with the spacecraft. [69] [70] Future flight s are expected to also be SATCOm capable, talking to India Geostationary Communication Satellites.
In the spring of 2009, a full-scale mock-up of the crew capsule was built and delivered to Satish Dhawan Space Centre for astronaut training. India was to shortlist 200 Indian Air Force pilots for this purpose. The selection process would begin with the candidates completing an ISRO questionnaire, after which they would be subjected to physical and psychological analyses. Only 4 of the 200 applicants were to be selected for the first space mission training. While two will fly, two shall act as reservists. [71] [72]
ISRO signed a memorandum of understanding in 2009 with the Indian Air Force's Institute of Aerospace Medicine (IAM) to conduct preliminary research on the psychological and physiological needs of the crew and the development of training facilities. [73] [74] IAM played a key role in determining astronaut training, the design of the crew capsule as per the anthropometric dimensions of the Indian population and a number of control and environmental systems as per psychological and physiological needs. [75]
The announcement of Gaganyaan by Prime Minister Modi immediately attracted an enthusiastic reaction from the Indian diaspora, and ISRO received millions of letters and emails from Indian residents as well as expats willing to volunteer as astronauts for the project. [76]
In January 2019, ISRO Chairman K. Sivan announced the creation of India's Human Space Flight Centre in Bengaluru for training astronauts. [77] The ₹1,000 crore (US$119.8 million) centre will train the selected astronauts in rescue and recovery operations, operations in a zero-gravity environment, and monitoring of the radiation environment. While the HSFC will initially operate out of ISRO headquarters, another facility, a dedicated campus, has been planned to be built near Bengaluru. The facility will include offices, housing, testing and integration facilities and will also employ a workforce of 1,000 people in the long term. [78]
An astronaut training facility will be established on a proposed 140 acres (0.57 km2) site near Kempegowda International Airport in Devanahalli, Karnataka. [79]
ISRO's Human Space Flight Centre and Glavcosmos, which is a subsidiary of the Russian state corporation Roscosmos, signed an agreement on July 1, 2019, for cooperation in the selection, support, medical examination, and space training of four Indian astronauts. [80] [81] An ISRO Technical Liaison Unit (ITLU) has been approved to be set up in Moscow for coordination activities. [82] Until September 2019, level 1 of the astronaut selection process was completed in Bengaluru. The selected test pilots underwent physical exercise tests, lab investigations, radiological tests, clinical tests, and evaluations on various facets of their psychology. [83] [84] By November 2019 the Indian Air Force had selected 12 potential astronauts who would then go to Russia for further training in two batches. [85]
As selection criteria require test pilot experience, any females will not be part of the first Indian crewed spaceflight. The first crewed flight will consist of a crew of three with one backup and this team of four went to Russia for astronaut training. [44]
In December 2019, the selection process came to a close, [86] [87] and four candidates began their 12-month training at the Gagarin Research & Test Cosmonaut Training Center (GCTC) on February 10, 2020. [88] The astronauts were trained for abnormal landings in various terrains, including forests, rivers, and sea. [65]
In February 2020, Indian astronaut candidates completed their winter survival training. [89] [90] [91]
ISRO has also proposed a ₹ 2,700 crore (US$320 million) plan to establish an astronaut training centre at Challakere in Chitradurga district. The facility would take at least 2–3 years to be established after the government's approval. [92] Following their training in Russia for unexpected and extreme situations, Indian astronauts were to return to India in March 2021 for the rest of their training in an Indian module. [17] However, due to the COVID-19 pandemic, training was put on hold from March 28 to May 11 and restarted on May 12, 2020. [35] CNES is supplying the flight system and training flight physicians and technical teams for the Indian Human Spaceflight Program. It is also collaborating and sharing its expertise in the domains of space medicine, astronaut health monitoring and life support. [93]
On the 91st Indian Air Force Day in 2023, the IAF released a video on Twitter, sharing a glimpse of the astronauts (without revealing their faces) training for the Gaganyaan mission. [94] While two or three out of the four astronauts will be selected to fly on the first crewed flight, one of the remaining backup astronauts on this mission will fly before the Gaganyaan prime crew on a mission to the ISS aboard Ax-4 in early 2024, as the second Indian astronaut in space after Rakesh Sharma, though the plan is yet to be finalized. The four have been conducting mission-specific training in India ever since they returned from Russia. [95] [96] [97]
On 27 February 2024, at the Vikram Sarabhai Space Center, Prime Minister Narendra Modi announced the names of the four designated astronauts who will be eligible for future flights as part of the Gaganyaan program, as well as an Indo-US joint mission (Ax-4) to the International Space Station. Kerala Governor Arif Mohammad Khan, Chief Minister Pinarayi Vijayan, Minister of State for External Affairs V. Muraleedharan, ISRO chairman S. Somanath and other high-ranking ISRO officials were present at the reveal. [98] [99] [100] [101] The selected astronauts are:
They were given Indian astronaut wings and the Gaganyaan mission logo and moto. [102] [103] The Indo-US joint mission astronaut is Shubhanshu Shukla, while Prasanth Nair was selected as his backup. Both were thus selected to train at NASA facilities. [104]
The necessity for additional astronauts on future space missions has already been acknowledged by ISRO. The broader pool of potential astronauts will be created in collaboration with the IAF's Institute of Aerospace Medicine. Candidates from experimental domains and those engaged in aeronautical research directly are of particular interest to ISRO. Angad Pratap, the Gaganyaan Group Captain, has stated that priority will be given to research work that will address the difficulties that ISRO faces in its technical endeavors. Even if researchers and military aviators might make up the majority of the initial batches, subsequent choices are probably going to be more diverse. The astronauts have to become experts in space theory, take part in simulator training, and interact with scientists. One essential part of the Astronaut Training School (ATS) is aero-medical training. Also required is survival training in a variety of settings, including the sea, the desert, and the snow. [105]
The ground uniforms were developed by the staff and students of the National Institute of Fashion Technology (NIFT), Bengaluru. Under the direction of the former NIFT director Susan Thomas, the NIFT team—which consisted of three students, Lamia Anees, Samarpan Pradhan, and Tuliya D—as well as two professors, Jonalee Bajpai and Mohan Kumar V—worked on designing the ground uniform for the Gaganyaan mission. The team highlighted the importance for the astronaut-designates' pockets to fit perfectly and the uniform must operate well in order to support their motions. Seventy possibilities were considered before the final design was chosen. The NIFT team examined various space agency uniforms, such as those from SpaceX and NASA. The theme that the NIFT team has explored is asymmetry. The group worked on a two-colored, asymmetrical style line. The design was commissioned in 2021 by the NIFT team, and in 2022, they handed the design to ISRO. [106] [107]

The Mysore-based Defence Food Research Laboratory (DFRL), a unit of the Defence Research and Development Organisation (DRDO), has developed dried and packaged food for astronauts. The food laboratory has developed around 70 varieties of dehydrated and processed food items that have undergone strict procedures to eliminate on microbacterial and macrobacterial nutrients. Special care has to be taken in the packaging, and the food items should be of limited weight, but at the same time should be high in nutritional quality. [108] Waste disposal systems for leftover food, liquid dispensing systems, food rehydrating systems and heaters adaptable to outer space conditions are in development, although the list of food products planned to fly aboard Gaganyaan is yet to be publicized as of August 2020. DFRL is expected to launch its Ready-to-Eat (RTE) space food by March 2021. The initial batch for the manned spaceflight Gaganyaan-H1 will carry foodstuffs sufficient for 7 days. [109]

India sent two flight surgeons to Russia and France to get hands-on experience in space medicines. The flights surgeons are doctors from the Indian Air Force, specializing in aerospace medicine. [110]
Gaganyaan and the Indian Human Spaceflight Programme are coming up, hence ISRO Chairman S. Somanath encouraged National Institute of Mental Health and Neurosciences (NIMHANS) to come up with solutions for spaceflight astronauts' psychological health. [111]
Unlike other nations that have carried out human spaceflight, India will not fly animals into space. Instead, it will fly humanoid robots for a better understanding of what weightlessness and radiation do to the human body during long durations in space. [112] [28] A legless humanoid named as Vyom Mitrā was displayed in January 2020 which is expected to fly onboard uncrewed experimental missions as well as assist astronauts on crewed missions. [113]
On 7 November 2018, ISRO released an Announcement of Opportunity seeking proposals from the Indian science community for microgravity experiments that could be carried out during the first two robotic flights of Gaganyaan . [114] [115] The scope of the experiments is not restricted, and other relevant ideas will be entertained. The proposed orbit for microgravity platform is expected to be in an Earth-bound orbit at approximately 400 km altitude. All the proposed internal and external experimental payloads will undergo thermal, vacuum and radiation tests under required temperature and pressure conditions. To carry out micro-gravity experiments for long duration, a satellite may be placed in orbit. Indian vyomanauts will perform four biological and two physical science experiments related to micro-gravity during the mission. [116]
India plans to deploy a 20-tonne space station named Bharatiya Antariksha Station, [3] as a follow-up programme to the Gaganyaan missions. On 13 June 2019, ISRO Chief K. Sivan announced the plan, saying that India's space station will be deployed 5–7 years after the completion of the Gaganyaan programme. He also said that India will not join the International Space Station program. The space station would be capable of harbouring a crew for 15–20 days at a time. It is expected to be placed in a low Earth orbit of 400 km altitude and be capable of harbouring three humans. Final approval is expected to be given to the programme by the Indian government only after the completion of the Gaganyaan missions. [117] [118] [119] [120]
ISRO is working to develop spacecraft docking and berthing technology, with initial funding of ₹10 crore cleared in 2017. [121] A Space Docking Experiment, or SPADEX, is being worked out by ISRO with systems like signal analysis equipment, high-precision videometer for navigation, docking system electronics and real-time decision making for landing systems being developed in various stages. As part of SPADEX, ISRO will launch 2 small satellites for testing. This technology is crucial for a space station as it will enable the transfer of humans from one vehicle or spacecraft to another. [122]
Human spaceflight is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously, without any direct human involvement. People trained for spaceflight are called astronauts, cosmonauts (Russian), or taikonauts (Chinese); and non-professionals are referred to as spaceflight participants or spacefarers.
A space station is a spacecraft which remains in orbit and hosts humans for extended periods of time. It therefore is an artificial satellite featuring habitation facilities. The purpose of maintaining a space station varies depending on the program. Most often space stations have been research stations, but they have also served military or commercial uses, such as hosting space tourists.
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. By the end of 2022, three countries and one private company (SpaceX) had successfully launched humans to Earth orbit, and two private companies had launched humans on a suborbital trajectory.
The Indian Space Research Organisation is India's national space agency. It serves as the principal research and development arm of the Department of Space (DoS), overseen by the Prime Minister of India, with the Chairman of ISRO also serving as the chief executive of the DoS. It is primarily responsible for space-based operations, space exploration, international space cooperation and the development of related technologies. The agency maintains a constellation of imaging, communication and remote sensing satellites. It operates the GAGAN and IRNSS satellite navigation systems. It has sent three missions to the Moon and one mission to Mars.
Satish Dhawan Space Centre – SDSC, is the primary spaceport of the Indian Space Research Organisation (ISRO), located in Sriharikota, Andhra Pradesh.
The Launch Vehicle Mark-3 or LVM3 is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Primarily designed to launch communication satellites into geostationary orbit, it is also due to launch crewed missions under the Indian Human Spaceflight Programme. LVM3 has a higher payload capacity than its predecessor, GSLV.
Human-rating certification, also known as man-rating or crew-rating, is the certification of a spacecraft or launch vehicle as capable of safely transporting humans. There is no one particular standard for human-rating a spacecraft or launch vehicle, and the various entities that launch or plan to launch such spacecraft specify requirements for their particular systems to be human-rated.
Gaganyaan is an Indian crewed orbital spacecraft intended to be the formative spacecraft of the Indian Human Spaceflight Programme. The spacecraft is being designed to carry three people, and a planned upgraded version will be equipped with rendezvous and docking capabilities. In its maiden crewed mission, the Indian Space Research Organisation (ISRO)'s largely autonomous 5.3-metric ton capsule will orbit the Earth at 400 km altitude for up to seven days with a two- or three-person crew on board. The first crewed mission was originally planned to be launched on ISRO's HLVM3 rocket in December 2021. As of November 2024, it is expected to be launched no earlier than 2026.
The ISRO Pad Abort Test was an Indian Space Research Organisation launch escape system test of its crew module as part of Indian Human Spaceflight Programme. The successful test took place on 5 July 2018.
Dr.V. R. Lalithambika is an Indian engineer and scientist who has been working with the Indian Space Research Organisation (ISRO). She is a specialist in Advanced Launcher Technologies and was leading the Gaganyaan mission to send Indian astronauts to space by 2022.
The Human Space Flight Centre (HSFC) is a body under the Indian Space Research Organisation (ISRO) to coordinate the Indian Human Spaceflight Programme. The agency will be responsible for implementation of the Gaganyaan project. The first crewed flight is planned for 2024 on a home-grown LVM3 rocket.
Indian Data Relay Satellite System or IDRSS is a planned Indian constellation of Inter-satellite communications satellites. It is planned to initially comprise two satellites, CMS-04 & IDRSS-2 in geostationary orbit. It will facilitate relay of information between various Indian spacecraft, in-flight launch vehicle monitoring and assist the Indian Human Spaceflight Programme.
Vyommitra is a female humanoid robot designed for space travel. She was designed at the Vikram Sarabhai Space Center in Thiruvananthapuram, Kerala and developed by the Indian Space Research Organisation (ISRO) to function aboard the spacecraft Gaganyaan, a crewed orbital spacecraft. Vyommitra was first unveiled on 22 January 2020 at the Human Spaceflight and Exploration Symposium in Bengaluru.
Test Vehicle Abort Mission-1 (TV-D1) was a high altitude abort test performed as part of the Gaganyaan program, initially set to be held on 21 October 2023 at around 02:30 UTC. Liftoff was delayed to 03:15 UTC due to weather issues, and five seconds before launch it was put on hold by the on-board computer due to an engine anomaly, as reported in ISRO's mission livestream. The launch occurred at 04:30 UTC, and the crew module successfully separated from the launch vehicle. The crew module was successfully recovered by the Indian Navy. India is the fourth country, after Russia, the United States, and China, to successfully test this technology.
Gaganyaan-1 will be the first uncrewed test flight of the Gaganyaan programme, with launch tentatively planned for March 1st, 2025.
The Bharatiya Antariksha Station, is a planned modular space station to be constructed by India and operated by the Indian Space Research Organisation (ISRO). The space station would weigh 52 tonnes and maintain an orbit of approximately 400 kilometres above the Earth, where astronauts could stay for 3-6 months. Originally planned to be completed by 2030, it was later postponed to 2035 due to delays caused by technical issues related with the Gaganyaan crewed spaceflight mission and the COVID-19 pandemic in India. As of December 2023, the first module is expected to be launched in 2028 on an LVM3 launch vehicle, with the remaining modules to be launched by 2035 on the Next Generation Launch Vehicle (Soorya).
Gaganyaan-4 will be the first crewed test flight of the Gaganyaan programme, with launch planned for 2026.

: CS1 maint: multiple names: authors list (link)Initially, the plan was the construct a new launch pad for the human space flight, but Sivan told the Express that due to paucity of time one of the two existing launch pads is being modified to meet the requirement.
It is proposed to utilise the existing launch pad with augmentation for carrying out the initial flights under the Gaganyaan manned space flight programme.[ permanent dead link ]
Giving out broad contours of the planned space station, Dr. Sivan said it has been envisaged to weigh 20 tonnes and will be placed in an orbit of 400 km above earth where astronauts can stay for 15–20 days. The time frame is 5–7 years after Gaganyaan, he stated.
