@Indx TechStyle we may actually have 3 unmanned flights instead of 2 because G1 won't carry ECLSS & to certify ECLSS we need atleast 2 unmanned flights, hence a total of 3 unmanned flights are required, since recently G1 flight is delayed to Mid-2024, I'm adding 6 more months delay to it , this is my most conservative estimate for Gaganyaan schedule
G1 - Dec 2024 to March 2025
G2 - Dec 2025 to March 2026
G3 - Dec 2026 to March 2027
H1 - Dec 2027 to March 2028 .
So, imo manned mission will definitely happen before Aug 2028, unless there is a big setback
