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.
