Gaganyaan: India names astronauts for maiden space flight

India has unveiled four Air Force pilots who have been shortlisted to travel on the country's maiden space flight scheduled for next year.

The Gaganyaan mission aims to send three astronauts to an orbit of 400km and bring them back after three days.

India's space agency Isro has been carrying out a number of tests to prepare for the flight.

In October, a key test demonstrated that the crew could safely escape the rocket in case it malfunctioned.

After its success, Isro said a test flight would take a robot into space in 2024, before astronauts are sent into space in 2025.

At a function at the Isro centre in the southern city of Thiruvananthapuram (formerly Trivandrum) on Tuesday, the four astronaut-designates were described as "dreamers, adventurers and valiant men preparing to go into space".

The officers, chosen from the Indian Air Force, were introduced as Group Captain Prashanth Balakrishnan Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap and Wing Commander Shubhanshu Shukla.

Prime Minister Narendra Modi and Isro chief S Somanath pinned badges with golden wings onto their shirts and Mr Modi described them as "India's pride".

"These are not just four names or four people. They are four powers who will carry the aspirations of 1.4 billion Indians to space. I congratulate and wish them all the best," he said.

Officials said the men were selected from a pool of Air Force pilots and had undergone extensive physical and psychological tests before being shortlisted.

They have undergone rigorous training for 13 months in Russia and are now carrying on with their gruelling schedule back home. A video screened at the event showed them working out in the gym, swimming and doing yoga.

On Tuesday, Isro also showed a glimpse of Vyommitra - Sanskrit word for "space friend" - the female humanoid that will be sent into space later this year.

The Gaganyaan Mission is India's first human space flight programme for which extensive preparations are underway at various Isro centres.

Named after the Sanskrit word for craft or vehicle to the sky, the Gaganyaan project has been developed at the cost of 90bn rupees ($1bn; £897m).

If it succeeds, India will become only the fourth country to send a human into space after the Soviet Union, the US and China.

Gaganyaan has generated a lot of interest in India, although it's coming decades after Soviet Union and the US started making trips to the low Earth orbit. Both have been in space since 1961. China became the third country to reach space in October 2003 when a Chinese mission spent 21 hours and orbited Earth 14 times. And the US and China have fully operational space stations in low Earth orbit.

An Indian astronaut also went to space as early as in 1984 when Rakesh Sharma spent nearly eight days on a Russian spacecraft.

Last year, India made major forays into space. The country made history by becoming the first to land near the Moon's south pole in August 2023.

Just weeks later, scientists launched Aditya-L1, India's first observation mission to the Sun which is now in orbit, keeping an eye on our solar system's most important and volatile star.

India has also announced ambitious new plans for space, saying it would aim to set up a space station by 2035 and send an astronaut to the Moon by 2040.
