ISRO: Upper stage engine of largest rocket now approved for Gaganyaan manned mission
India’s space agency ISRO today announced that it has completed engine tests of the upper stage engine of its LVM rocket, a variation of its GSLV rocket and its most powerful, that will be used on its Gaganyaan manned orbital mission presently scheduled for launch in 2025.
In order to qualify the CE20 engine for human rating standards, four engines have undergone 39 hot firing tests under different operating conditions for a cumulative duration of 8810 seconds against the minimum human rating qualification standard requirement of 6350 seconds.
Before the 2025 manned mission, ISRO plans four more launch abort tests (one has already taken place) and three unmanned Gaganyann orbital demo missions. Two of those unmanned demo flights are scheduled for this year.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
