I had a lot of fun watching Dr. Tarter's interview. For me, the most memorable part was particularly when they got into the discussion of trying to detect ET's and Dr. Tarter's experience with that. She mentioned two specific "false positives" when she thought she had detected ET life, but both ended up being duds—one was a distant airport and one was the SOHO space craft. For me, though, the most memorable part was when Dr. Tarter mentioned that for the second false positive, she forgot to inform her distant colleagues in CA that they realized the signal wasn't ET life, and so they stayed up the whole night watching it and waiting, thinking there was still possible life. This was kind of just a funny situation, but it also highlighted to me how exciting those searches must have been for everyone to be willing to stay up for days in anticipation.
One question I would've asked Dr. Tarter is, "Do you think that any signs of organic life elsewhere—even if it's just small bacteria or prokaryotes—are indicative that larger life exists elsewhere?" I'd ask this because it's always kind of unclear to me how to feel about news stories that cover things on the nature of "distant life discovered." For example, I saw an article a while ago that stated that Mars could've potentially had conditions to support microscopic life, but I'm not sure how important discoveries like this would actually be for determining if there is genuinely intelligent life elsewhere.

I also really enjoyed Dr. Tarter's discussion of trying to find ET's. It made me think a lot about the scientific method and the struggles of it from a morale perspective; scientists are constantly trying to make new discoveries, but there is often a long drought between these discoveries. Sometimes, people even work on a project for life just to be later disproven. I think this is a testament to science's remarkableness because people are still willing to pursue science despite so many setbacks. This process, while demanding, is what ultimately drives progress and innovation in our world.
