RSI internship

I'm currently a freshman in college doing mechanical engineering. I had a couple friend's get this internship as seniors in high school and really liked this position. I was wondering since I'm a freshman and don't have a lot of experience and was wondering if it's really competitive for this specific opportunity. For reference I have a 4.0 (which is my best attribute), I'm involved in 3 clubs, have a job and am doing some student lead research about rockets. The deadline is at the end of February and I do plan to email multiple researchers at ORNL and was wondering if there is anything else I can do to have a better shot and what I have done so far is good and up to par to get the internship. (I live close to ORNL if that has any relevance)
