BENGALURU: The first unmanned flight as part of the preparations for the ambitious Gaganyaan project originally planned for this year and then brought into the first half of 2021 due to Covid-19, will now only occur at the end of next year. Isro will eventually launch a second unmanned flight as well, now scheduled for 2022 before launching humans into space.
Isro President K Sivan told TOI that the human qualification process is progressing well and is expected to be complete in the second half of next year. TOI was the first to report the postponement of the unmanned / unmanned flight and also the fact that the human mission is likely to miss its original deadline as well.
As part of the unmanned flight, Isro plans to send a humanoid (indigenously developed). In June, when it became clear that the first unmanned flight will not happen this year, Sivan said: “Whether we will launch two unmanned missions next year will depend on emerging situations, we will have to decide based on what happens in the coming months. If the effects of Covid continue, we may need to review some of our plans. ”It is now clear that Isro will only be able to launch one unmanned flight next year.

Additionally, last week, Isro pointed to the first human-rated S200 engine box for Gaganyaan’s first unmanned mission. “The high-thrust solid propellant belt thrusters – S200 – play an important role in the human-rated GSLV MkIII. In order to qualify the amplifier, a lot of new design features have been introduced into the hardware, ”said Isro.
Isro’s heavy lift launcher, GSLV MkIII, identified for the Gaganyaan Mission, is in the process of being qualified for humans. The human rating of the S200 engine case is another successful industry collaboration.
“… The first critical reinforcement segment of the engine housing with a diameter of 3.2 meters, 8.5 meters in length and a weight of 5.5 tons has been developed and delivered by L&T,” said Sivan.
Describing it as a great achievement, Sivan said the next step would be to achieve human qualification of all the hardware required for the mission. S Somnath, director of the Vikram Sarabhai Space Center (VSSC) had previously told TOI: “… The target reliability for human-rated launch vehicles is 0.99, which means that statistically only 1 in 100 can be unreliable. And, for the very important crew exhaust system, we are aiming for over 0.998, which means we want almost 100% reliability. ”
