Hello Aspirant,

There is actually no competition between the two categories, both have their own importance.

Salary of a Scientist/ Engineer SC ranges between Rs 56,100 to 1,77,500 and that of a Scientist/ Engineer-SD is Rs 67,700 to 2,08,700.

An astronaut earns around 92,479.

So, range of salary is quite the same, everything else matter on your performance, abilities and experience.

Hope this helps!
