All You Need To Know

  • Prime Minister Narendra Modi will review the progress on the Gaganyaan human spaceflight programme and dedicate three facilities of the Indian Space Research Organisation (ISRO) to the nation during a visit to the Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram on February 27. During the visit, PM Modi will also commend the four test pilots by awarding them with their ‘astronaut wings’.

  • The selection process took place in 2019 at the Institute of Aerospace Medicine in Bengaluru, which is under the Indian Air Force. Following multiple rounds of selection, Prashant Nair, Angad Pratap, Ajit Krishnan, and Chauhan were approved by IAM to be part of the Gaganyaan mission.

  • Mr. Modi is also likely to announce the names of the astronauts of the Gaganyaan programme, which, reportedly, includes a Keralite. Mr. Modi will also bestow the ‘mission patches’ on them.
  • Gaganyaan, expected to be launched in 2025, envisages demonstration of human spaceflight capability by sending astronauts to orbit and returning them safely to earth.
  • Mr. Modi, who is scheduled to visit VSSC will dedicate the Trisonic Wind Tunnel established at the VSSC, integration facilities for the Polar Satellite Launch Vehicle (PSLV) set up at the Satish Dhawan Space Centre, Sriharikota, and the Semi-cryogenic Integrated Engine and Stage Test Facility (SIET) at the ISRO Propulsion Complex in Mahendragiri in Tamil Nadu. The three facilities have been developed at a cost of ₹1,800 crore.

  • The Trisonic Wind Tunnel has an overall length of 170 metres. With a test section size of 1.2 metres, it produces a “controlled uniform airflow” over scale models of rockets and aircraft to assess their aerodynamic characteristics for optimal design development.
  • The wind tunnel, which is the first of its kind in the country, has a Mach number range of 0.2 to 4, which means it can generate speeds ranging from subsonic to supersonic up to four times the speed of sound (Mach number 4).

  • The Trisonic Wind Tunnel will provide self-reliance in the end-to-end design of upcoming launch vehicle projects. The new PSLV Integration Facilities (PIF) at Sriharikota will give the ISRO the capability to increase the number of PSLV missions in a year to 15. At the new facility, the PSLV rocket will be integrated parallelly with the refurbishment of the launch pad, saving time.

  • SIET will give the ISRO the capability to test the SCE-2000 semi-cryogenic engine which uses refined kerosene (named ISROSENE) and liquid oxygen as propellants and the rocket stage. The facility is at the ISRO Propulsion Complex in Mahendragiri.
  • ISRO chairman S. Somanath, VSSC director S. Unnikrishnan Nair and directors of various ISRO centre’s will be among those present.
