India’s First Human Space Mission Gaganyaan’s Test Flights Scheduled For February 2023; All You Need To Know

The mission includes three space flights: two unmanned ‘Abort missions’ to test for crew safety, followed by the manned space journey. The abort missions are meant to test the systems that can help the crew escape from the spacecraft mid-flight in case of a failure.

The Indian Space Research Organisation (ISRO) will start a series of test flights for India's maiden human space flight mission from February next year, a senior official said here on Thursday.

The space agency also plans to deploy the heavy lift Chinook helicopter and the C-17 Globemaster transport aircraft for testing the crew module, which will carry astronauts into the orbit for three days as part of the Gaganyaan human space flight mission, R Umamaheshwaran, Director of ISRO's Human Space Flight Centre said.

17 test launches planned

Addressing the India Space Congress here, he said scientists at ISRO had completed the design of the Environment Control System, which will ensure ambient living conditions for astronauts in the crew service module when they are orbiting the earth.

At least 17 different tests are planned by ISRO next year before it carries out the unmanned space flight in December next year.

Progress on crew module

Umamaheshwaran said the task of designing the crew module and environment control system was a challenging one as the astronauts should feel comfortable even during the re-entry phase, when the temperatures outside the space capsule could reach over 2000 degrees celsius.

"The crew module, where the astronauts are supposed to sit and fly, is completed and the fabrication work is on. Within six months, we will get the crew module," he said on the sidelines of the event organised by the SatCom Industry Association. 

Umamaheshwaran said the environment control system was a critical element of the project as it provides ambient living conditions in the crew module. "We have to provide oxygen, remove carbon dioxide, remove humidity, maintain temperature and also ensure there is no fire hazard. This is a very complex technology which no country would give us," he said.

The senior scientist said it was decided to develop the environment control system indigenously. "We have the capability to design, so we are doing that and that only is taking a little bit of time. We have completed all the design and now is the time to prove that whatever has been designed is safe enough. That is the entire effort," Umamaheshwaran said.

Collaboration with Russia

He said four candidates have been shortlisted to undertake the spaceflight and have already completed their initial training in Russia. ISRO had signed a contract with Russia based Glavkosmos in 2019 for the training of Indian astronauts. This included the procedures to select the candidates, their medical examination, and space training. 

The prospective Gaganyaan astronauts studied in detail about Russia’s Soyuz manned spaceship, which has for long been used by multiple countries to carry humans and supplies to and from the international space station.

The shortlisted astronauts are currently undergoing further training at the Astronaut Training Facility in Bengaluru, he said.

About Gaganyaan mission

The Gaganyaan mission will be ISRO’s first manned space mission and will take three Indian astronauts, including a woman, on board the GSLV MK III launch vehicle to the Earth’s low earth orbit. The spacecraft will circle the earth for 5-7 days and will showcase India’s capability in the science and technology sector.

Prime Minister Narendra Modi had announced the Gaganyaan Mission in his Independence Day address in 2018 with a tentative target of achieving it in 2022, when the country completed 75 years of freedom from colonial rule.

However, the Covid pandemic led to several delays and the first Indian astronauts are likely to undertake their maiden spaceflight by the end of 2024 or early 2025.

The mission includes three space flights: two unmanned ‘Abort missions’ to test for crew safety, followed by the manned space journey. The abort missions are meant to test the systems that can help the crew escape from the spacecraft mid-flight in case of a failure.
