On 10 February 2020 Indian candidates for a spaceflight began the planned training program at the Russian Cosmonaut Training Center. The program has been performing under the contract between Glavkosmos, JSC (part of the “Roscosmos” - Russian State Space Corporation) and the Human Spaceflight Centre of the Indian Space Research Organisation (ISRO). The contract was signed on 27 June 2019. The document implies the support of Glavkosmos in selection of candidates, their medical examination, and various aspects of space training. After thorough selection, the four Indian Air Force fighter pilots became the ISRO candidates for the spaceflight. The 12-month training program includes comprehensive and biomedical training of the Indian candidates, which will be combined with regular physical practices. In addition, they will study in detail the systems of the Soyuz manned spaceship, as well as they will be trained in short-term weightlessness mode aboard the special Il-76MDK aircraft. The Indian pilots will also be trained to act correctly in case of abnormal landing of the manned spaceship descent module in various climate and geographic zones. The most part of the training will take place at the Yuri Gagarin Cosmonaut Training Center (Zvyozdny Gorodok, Moscow region, Russia) facilities.
