Hi, I have a really big problem, guys. So any help in the form of advice will be really appreciated. Ryt now I'm gettin my undergraduate degree in a medical school. But i really want to work for NASA ( not as a doctor ). So I wanted to know 1.) If it is possible for me to do MS in a physics realted field through GRE. ( although i'm from a medical background ) 2.) And would gettin a phd in physics would be of any help to get a job at NASA.
