ISRO would now stitch them up into a complete project and present a comprehensive project report to get a formal approval of the government, Dr. Sivan said.
According to NDTV, the Indian Space Research Organization (ISRO) plans to send three astronauts into space over the next few years, with the first mission taking place within 40 months from now at a cost of Rs. 90 billion ($1.28 billion). Before undertaking the launch, we will have two unmanned missions.
Mangalyaan is another Indian space project.
Prior to the actual launch by 2022, the Indian Space Research Organisation will have two unmanned missions and spacecraft will be fired using Geosynchronous Satellite Launch Vehicle Mark-III, Sivan said.
Speaking from the ramparts of the historic red fort in New Delhi, Modi said it was a "dream" for the country to send a citizen to space before it celebrates 75 years of independence.
"We've debated for long on the tangible and intangible benefits of manned space missions", said B.N. Suresh, former director of the Vikram Sarabhai Space Centre, Thiruvananthapuram. It would demonstrate that India would be on par with the developed countries in this area.
Senior Isro officials said the agency had been preparing itself for manned space flight for more than a decade through the development of relevant technologies such as a space capsule, a giant rocket for heavy payloads, operational systems to recover space capsules from low-Earth orbit and a crew escape system.
If successful, India would be the fourth nation to achieve that feat. He was part of the crew on Soyuz T-11 launched on April 2, 1984 from the Baikonur Cosmodrome in Kazakh Soviet Socialist Republic, a part of the then Soviet Union.
In 2007, India tested its first re-entry technology where a 550 kg satellite was sent into the orbit and brought back to earth safely in 12 days. She was one of the seven crew members who died in the Space Shuttle Columbia disaster in 2003.
The satellite, later rechristened South Asian satellite, was launched in May 2017.
