The ambitious mission, dubbed “Gaganyaan”, will carry three Indian astronauts to space for seven days by 2022 at the estimated cost.

The project announced by Prime Minister Narendra Modi earlier in August, on successful completion, will make India the fourth nation in the world to do so.

If successful, India would be the fourth nation to achieve the feat after the US, Russia and China.

The mission would be launched using ISRO’s own capabilities.

“Our country has been making a lot of progress in the area of space (science). When India celebrates its 75th Independence Day, or even before that, an Indian son or daughter will undertake a manned space mission on board ‘Gaganyaan’, carrying the national flag,” Modi had said from the Red Fort.
