An astronaut or cosmonaut is a person train by a human spaceflight program to command, pilot; or serve as a crew member of a spacecraft. Although generally reserved for professional space travelers; the terms sometimes apply to anyone who travels into space, including scientists, politicians, journalists; tourists. Until 2002, astronauts sponsored and trained exclusively by governments, either by the military or by civilian space agencies.
With the suborbital flight of the privately funded SpaceShipOne in 2004; a new category of astronaut created: the commercial astronaut. ISRO has joined the Indian Air Force to select and train 10 spacecraft personnel for the country’s first human-space mission or ‘Space Flight’ project or Gaganyaan. They have our own criteria and requirements for selecting our crew and training them and have submitted the same to the IAF.

IAF’s Institute of Aerospace Medicine

The first two rounds of training of the crew will take place at the IAF’s Institute of Aerospace Medicine (Bengaluru); the remaining phase of training will abroad. Shivan, who is proposed staffing numbers, has suggested that 10 candidates be trained for the ‘astronaut’ project. They will finally pick three of them. K Sivan; ISRO chairman The countries that have been considered are Russia and France. But no final decision has taken yet.

The Institute of Aerospace Medicine (Bangalore-IAM); which is to the Armed Forces Medical Services (Bangalore-IAM); is the only organization to research the space drugs not only in India but also in Southeast Asia. So it trains space personnel research and air force personnel and pilots. The organization had previously clinched the Indo-Soviet space humanitarian mission in the 1980s. It does research in aerospace medicine and trains airmen and pilots.

Space flight programme

The institute, earlier which was named as the Institute of Aviation Medicine; given medical support to the Indo-Soviet; space flight programme in the 1980s. The infrastructure at IAM is one of the best in the country;  so ISRO wants to collaborate with IAM to train the crew members of Gaganyaan mission Bipin Puri, director general, Armed Forces Medical Services (AFMS).
Shivan explained that ISRO will take two non-human missions to prevent the threat of human life. In these missions, human-like robots are sent. The first unmanned robot-bound space will scheduled in December 2020. But the second non-human experiment will held in July of 2021. Lastly, human spaceflight will conducted in December 2021. If Gaganyaan is successful, India will become the fourth nation to achieve the feat.
