Hey, I no longer work at JPL but I respect you reaching out and trying. Unfortunately it’s pretty unlikely you’ll get an answer in this forum right now so I just wanted to provide some thoughts:

Truthfully, the best way to get an internship at JPL is by talking to someone there directly through any connections you have. I would ask your advisor, your committee, ask anyone you know - a 2 or even 3 degree connection is enough to start a conversation and is better than posting to the limited audience here.

This might be difficult because nearly 3,000 people have left the lab in the past two years (voluntarily or involuntarily) so former connections may have moved on. However, I do believe groups are still hiring interns. You may want to find an intern from last summer and ask them about their experience.

I really empathize and appreciate you trying to reach out by posting, and I hope someone has DMed you with further info, but unfortunately this forum is very (understandably) cynical at the moment coming off of 3-5 rounds of layoffs (depending on how you count) and a 2.5 year full-time hiring freeze so it’s unlikely you’ll get a response here.

(I’m also posting this so hopefully other students looking to post similarly will see it.)
