Respected Sir,

Thanks for contacting Career 360.

I would recommend you to work towards studing BSc. And MSc.Physics from IIST as they are more centric towards Space and science. Or I'll recommend you to apply for IISc , IISER and NISER as they are premier colleges for doing science.

Or else , you could study Mechanical /Aerospace Engineering. Mechanical Engineers are needed for hands on making various Space resulted structures. These are the two options.

Hope I was able to help you.
