Brad reconnects with Scarlett Koller, who he first met as an MIT sophomore for Amazon’s original Prime Air intern cohort, back when drone delivery was a “60 Minutes” segment, not a product. She’s since delivered on SpaceX Crew Dragon, NASA Perseverance, and Amazon Kuiper, and now runs Mithril , a deep tech startup reshaping space sensing. They trade stories on why NASA’s shuttle veterans cared so much about a simple handle, why people are harder to engineer than radiation, and how an antenna the size of a volleyball court, controlled to the thickness of a sheet of paper, could keep us from losing low Earth orbit.
