I Am Stewart Weinstein. I am a NASA Engineer who worked on various projects such as the Hubble Space Telescope. AMA!
I was talking to some people in /r/nasa and /r/askscience and they said I should do an AMA so here I am. My son told me that great questions are asked so I'm looking forward to the experience. My son will be helping with formatting, so hopefully I won't look stupid. I already showed proof to the mods, but here if you'd like to take a peek, here it is.
The proof is from Servicing mission 3A, but I also have worked on various other aspects of the Hubble.
Once, again, I'm greatly looking forward to your questions.
Edit: I'm going to a movie, but I'll answer any lingering questions when I get back. Thanks for the fantastic questions, and you can keep asking them, I'll still be around!
Edit #2: I'm back and will be answering more questions!
Edit #3: I'm going to go to bed now. Your questions have amazed and astounded me. I appreciate each and every one of you. I will most certainly answer lingering questions in the morning. Thank you so much!
Edit #4: I'm awake and will answer any questions you still have.
Edit #5: This was amazing. I'll still answer questions, if you have them. Thank you so much for all of the questions. Keep looking up, keep dreaming!
