Hello,

To get a good job in NASA, B.sc physics degree is not enough, you must have done M.sc and must be involved in some Ph.d then only you'll be eligible enough for NASA. Therefore you need to work a little bit more harder to get a high quality job in NASA.

You can also go for following courses:

1. B.E. or

2. B.Tech. or

3. M.Sc.
in space technology or aeronautical engineering.

You can also go for IIT JAM. If you do well in your master's degree you might end up with an offer from NASA.

Hope this helps.

All the best!!
