🟣 Guest: Dr. Mike Rubenstein

📜 Actively Steerable Femtosat Constellations for In-situ Exploration of Saturn’s Rings, Atmosphere, and Magnetosphere https://www.nasa.gov/directorates/stmd/niac/actively-steerable-femtosat-constellations-for-in-situ-exploration-of-saturns-rings-atmosphere-and-magnetosphere/

👉 All 2026 NIAC Selections https://www.nasa.gov/directorates/stmd/niac/niac-studies/niac-2026-selections/

Saturn's rings are dense. Sending one flagship probe through them makes no sense. It'll most probably be lost. But sending a swarm of small cheap probes does. Even if a lot of them won't survive, you're still getting lots of data. This is exactly what this NIAC project is proposing.

00:00 Intro

00:25 [@festerallday] if a civilization isn't detected by SETI did it even exist?

02:20 [@tommix6016] If White Holes were to exist, would they be detectable?

03:49 [@vistotutti6037] Does SETI have access to the Vera Rubin data stream?

06:26 [@setaihedron] So we are going to trust that the most corrupt government in modern history is honest about what it is filtering from the data?

09:00 [@MelindaGreen] How would I prefer the Universe end?

12:37 [@paulwilson1529] Will the Earth become tidally lock to the Sun?
