India tests upgraded rocket engine
The new colonial movement: India’s space agency ISRO has successfully tested an upgraded version of the Vikas rocket engine it uses in its PSLV and GSLV rockets.
The test was conducted on Sunday, and validated the performance adequacy of Vikas Engine to be used in the upcoming second developmental flight of GSLV Mk-III
Vikas Engine, a workhorse liquid rocket engine designed by the Indian Space Research Organsiation (ISRO), powers the second stage of Polar Satellite Launch Vehicle (PSLV) of India. It also powers the second stage and the fourth strap of Geosynchronous Launch Vehicle (GSLV) and the twin-engine core liquid stage (L110) of GSLV Mk-III.
Essentially India here is doing what SpaceX did with its Merlin engine. Rather than start over with a new engine, they are upgrading it, a process that is faster and less expensive. And as they do it, they remain operational and competitive in the launch market, with as many as five launches now scheduled before the end of 2018.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows 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. 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. Only now does it appear that Washington might finally 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.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

I like that they are reusing the engine in multiple stages and boosters. J-2/RL-10 approach! Well done.
