	Description:		Devon Island, a polar desert in the High Arctic, is one of the most convincing Mars analogs on Earth. That's why Pascal Lee built his NASA-affiliated research base there. On this episode he returns to discuss his summer field work, Martian volcanoes, and to discuss possible alternatives to NASA's plans for the Artemis lunar base.There's a lot to know, and he brings deep passion—and some controversy—to the conversation! Headlines: Polaris Dawn mission success: The crew completed the first-ever commercial spacewalk, with all four members exposed to the vacuum of space. SpaceX FAA dispute: The company faces potential fines of $630,000 for alleged launch violations, leading to a heated exchange between SpaceX and the FAA. Mars volcano discovery: Researchers found evidence of a 1000-mile wide magma plume under Olympus Mons, raising questions about potential volcanic activity on Mars. Main Topic - Lunar Exploration and Artemis Program: Dr. Pascal Lee's summer research at the Houghton Mars Project Field Station: The team tested drilling equipment for future lunar missions and explored the use of drones for Mars helicopter simulations. Critique of current Artemis program strategy: Dr. Lee argues that focusing on sortie missions to the South Pole is premature and potentially counterproductive. Alternative base location proposal: Clavius Crater is suggested as a more suitable site for a lunar base, offering scientific value and better logistics. Water extraction challenges: Dr. Lee discusses the complexities and uncertainties surrounding water ice extraction at the lunar South Pole. Starship as a water delivery system: The potential for using SpaceX's Starship to deliver large quantities of clean water to the Moon is explored. Importance of establishing a fixed base: Dr. Lee emphasizes the need for a stable infrastructure to support long-term lunar exploration and science. Power concerns for lunar bases: The limitations of solar power are discussed, with nuclear power suggested as a more viable option for long-term operations. International competition considerations: The episode touches on how other countries' lunar ambitions might influence NASA's plans.
