Hosted by Lester Nare and Krishna Choudhary, this episode is a
full-spectrum moonshot: why Artemis II matters, how the mission
actually works (SLS, Orion, translunar injection, free-return
trajectories), and a first-principles teardown of the most common
Apollo “hoax” claims—Van Allen belts, waving flags, shadows, and
“why aren’t there stars?” We also run a quick Rundown of wild
science headlines (ancient cave art, elevation-dependent warming,
dogs and vocabulary, and peptide bonds in deep space), before
coming back to the core question: what it takes to send humans
safely around the Moon—again. Summary Artemis II mission profile —
what “free return” means, why TLI timing matters, and what Orion is
doing in high Earth orbit before the Moon. SLS vs Saturn V — the
engineering and risk trade-offs behind modern human-rated heavy
lift. Apollo myths, explained — radiation belts, camera exposure
physics, and why the “flag,” “shadows,” and “no stars” arguments
don’t survive basic mechanics and optics. Proof Apollo happened —
retroreflectors, orbital imagery, and the reality that the world
was watching. Show Notes NASA Artemis Program NASA Orion Spacecraft
