Hi asish

First of all I am appreciating you for choosing a good goal. To become a space scientist you need to join intermediate in any science stream with physics. After completion of your intermediate you need to join in degree of physics or B.Tech astrology. After that you need to get your masters degree from space physics it is help to get a chance to work in any organization related to space research like NASA,ISRO and many more. And for this Program, Govt conducts an Entrance Exam every year and selects only few students i.e in 100s not like other competitive exams where thousands of students are selected. During the program,the University gives students variety of opportunities in field of Science and Space Technology where any student can choose the course he/she likes and can choose projects followed by their field etc.

So best of luck.
