And in the meantime, India is testing an engine for human spaceflight

As European politicians prepare to fund the autonomous manned flight programme, India is set to become the fourth space power capable of sending humans into space. A good technical performance for a state that does not have the same financial power as Europe, behind which some of the key technical sectors fall short.

Initially, the Indian space agency had launched one or two . planned to send Astronaut 75. Indian on the occasion ofAnd Anniversary of Indian Independence in 2022. but, covid-19 crisis forced the country to postpone this inaugural flight until 2024. This will be preceded by two unmanned flights, each scheduled for the first and fourth quarters of 2023. Robot equipped with humanoid sensor, Capsule a. will be involved in To revolve around 400 km for a 7-day flight before landing in the Arabian Sea off Ahmedabad.

much less publicized than NASAI’esa Or the space agencies of Russia and China, the Indian space agency continues its program manned flights Started many years ago. Gaganyaan, as it is the name of the programme, has already conducted several tests, including a sub-orbital flight, with atmospheric re-entry of the 3.7 tonne (care in 2014) prototype capsule (without astronauts). Testing of a rescue tower with a model of a 12.6 ton capsule. Note also the flight of the experimental capsule SRE-1 in 2007, which lasted 12 days in orbit.

A version of the launcher for robotic exploration missions qualified for human spaceflight

few days back,ISRO successfully performed a static test a emphatic to help throwable Strong for Gaganyaan program booster Tested is the manned flight version of the S200 thruster which equips Launcher GSLV Mk III. In this configuration it is named HS200. The test lasted for 135 seconds which is Duration Operation of the first of the three stages of GSLV Mk III.

Instead of developing an entirely new launcher specifically dedicated for manned flights, India preferred to develop a manned version of the GSLV Mk III. The launcher, commissioned in 2017, has a 10 ton low orbit and 4 ton a . able to launch transfer class geostationary. He launched lunar missions especially Chandrayaan 2 and 3 and Venus (Shukrayan-1) and Mangalyaan 2, the second mission bound for Mars, should launch a probe.

India wants to send people to space by 2022

Which will be the fourth country to send its astronauts to space on its own? Certainly not Europe, which likes to cooperate in international programs, nor Japan, which is technologically lagging behind in this area. It must be India which has the political will to do so and is slowly acquiring the technology to do so. Its prime minister has just set a target. It will be 2022!

After USSR, USA and China, will India be the fourth nation to send men to space through its own means? Yes, if we trust the speech to the nation that Indian Prime Minister Narendra Modi has given on the occasion of Independence Day. Beyond the political will that other grassroots countries lack, India also has the financial and technical capacity to achieve this feat.

Looking at the latest technological advancements by ISRO (Indian Space Agency), and if we compare its program with the program implemented to send it to China first taikonaut In space (Shenzhou 5, October 2003), the 2022 deadline seems optimistic to us. Especially since two unmanned demonstration and test flights are planned before the manned flight. This first manned mission will certainly see a crew of two or three Gaganauts (the name given to Indian astronauts), perhaps accompanied by a woman, remain in orbit around the Earth for a short week.

Over the past ten years, India has been acquiring and mastering critical technologies for manned flight (orbit return, atmospheric re-entry, heat shield, etc.). If the effort continues, there is no doubt that by 2025 it will be successful in sending the Gagans into space.

steps taken successfully

In 2007, ISRO successfully launched a . used atmospheric re-entry capsule (SRE-1 mission) after several days in space in a circular then elliptical orbit of 485 x 639 km. In 2014, she launched a Demonstrator of a manned capsule Weighing over 3.7 tonnes, measuring 3.1 m in diameter and 2.7 m in height. baptism care, for Crew Module Atmospheric Re-entry Experiment, the capsule was large enough for a crew of three. In early July, the crew’s emergency evacuation system was successfully tested during a capsule extraction test in the event of a problem at the launch pad.

Finally, India has opened a training center for Gaganuts in Bangalore with the aim of training and preparing at least four of them so that at least two, or even three, of them can undertake orbital flights lasting several days.

India wants men in space and a reusable launch vehicle

India, Asia’s other rising space power, wants to do the same with its cumbersome neighbor China. Even better. Its ambitions are enormous: to launch a manned flight before the end of the decade and to create a reusable satellite launch system, in essence, an unmanned shuttle.

If space sector makers and most space agencies are directly or indirectly interested in the reusability of launchers, India is the only country betting on everything reusable to reach space. However, it has a family of pitchers that largely meets its needs. Currently, it is developing a reusable two-stage launcher of the TSTO (Two Stage to Orbit) type that would look like a Spacecraft, No launch date has been announced but it is believed that a exhibitor The flight test could be done this year. Another project related to reusability, SRE Orbit Return Capsule (Space Capsule Retrieval Experiment) designed to fly experiments (50 Kilogram) in weightlessnessThen bring them back to the ground.

Europe has decided that next generation launcher (NGL) which will replace the present family AriadneBy 2025, will not be reusable.

All reusable, a falsely good idea?

This idea of ​​reusability can quickly become a dead end. On paper, a . use of Launcher Reusability has something to draw even more, as its reliability increases as it is used due to the progressive correction of defects encountered on the equipment.

For many, however, it is still too early to begin the development ofreusable flooring Capable of performing significant. The technologies required for this type of floor are only partially assimilated. For today’s launchers, their design makes it impossible to envisage material reuse. especially those which are used for thermal protection and construction floors.

Indians in space soon?

Reusing a floor is a real logistical headache and, consequently, an economic crap. between its recovery, on land or on the high seas, its restoration, its certificate As for the flight and its integration into the launcher, the reuse proves longer and more expensive than the consumable phase, produced in approximately ten copies each year. The spacecraft example is instructive. With only a partially reusable operational system (the ventral tank and booster were lost), it required several months of overhaul between two flights when it had to do dozens of flights a year!

Another major program is to send Gaganauts (the name given to Indian astronauts) into space. in spite of halt in its space programDue to failures in 2010, India reaffirmed that it would be ready to launch two astronauts on its own by the end of this decade. They will fly aboard a homemade space capsule launched by a GSLV qualified for manned flight. Keeping this in mind, ISRO has opened an Astronaut Training Center in Bangalore. The objective is to prepare at least four of them so that two of them can perform several days of orbital flight.
