The celestial bond that connects ISRO with India Inc
The celesetial bond
About 80% of the launch vehicle and 60% of the spacecraft are made privately by the 400-odd companies that work with ISRO.
Centum for micro-electronics
Being one of the largest contractors of ISRO, Centum makes 50 different varieties of components for satellites and launch vehicles. The company has specialised in micro-electronic components that have repeated functions in many parts of rockets and satellites.
L&T for heat shield
It also made the inter-stage connectors and the heat shield for the spacecraft. Since facilities are expensive, they have to be used for multiple projects, thereby offering more business opportunities.
Godrej for cryogenic engines
It also makes liquid engines that will be used to raise the orbit before the spacecraft begins its journey to the moon. They will also be used to slow it down once it reaches the moon and then even further during descent.
Avasarala for heat pipes
These transfer heat from one area and dissipate it elsewhere and are critical in space where it may be cold on one side and hot on the other. On the moon, temperatures can reach 100 degrees Celsius during the day — one day on the moon is equal to 14 days on earth.
A moon mission is business as usual for most of these companies. And yet, it is different, as some of their components will be tested in tough manoeuvres in one of the harshest environments.
