Hello Harsh Tiwari , Pursuing courses is the first step to become a scientist. Firstly, choose a specialization in which field you want to become a scientist and pursue courses accordingly. “If you want to become a scientist at NASA, then you must choose science, technology, engineering and Mathematics centered education”.

Hope it will be helpful for you :)
