In this age of rapidly advancing AI and robotic technology, do we still need to send humans into space? The argument has long been that people can do things better and faster off-Earth, but the changing face of robotic tech has some feeling otherwise. This week's guest is a returning friend of the show, Dr. Pascal Lee, who has thoughts on how and when robots may perform better--and more safely--than humans in space, and then, of course, Tariq and I worry about how our mechanical masters might take our place in the cosmos. Pascal also reports on his recent experience with the National Academies' report on the human exploration of Mars. Join us!

Headlines:

• NASA Unveils Major Overhaul to Artemis Lunar Program, With Arrtemis II & II Facing Delays and A Shift in the Lunar Landing Timeline.

One of the most exciting missions to ever journey to the outer solar system has the be the Dragonfly multi-rotor helicopter that will head to Saturn's moon Titan in 2028. The car-sized probe will arrive at that strange, frozen world in 2034, descending into the soupy, smoggy atmosphere and then taking flight before it even touches the ground! We spoke with the mission's Principal Investigator, Dr. Elizabeth "Zibi" Turtle, about the mission's origins, current progress, and what to expect in the coming years. She also took us through a narrated tour of the surface of Titan, with its hydrocarbon sand dunes and methane seas. The Dragonfly mission will be an adventure of a lifetime!

Headlines:

• NASA's Artemis II Moon Rocket Aces New Fueling Test
• Boeing Starliner is Rated a "Type A" Mishap and Faces More Launch Delays
• Perseverance Rover Gets Instant Mars GPS-like Functionality

Main Topic: NASA's Dragonfly Mission to Titan

• Dr. Elizabeth Turtle explains Dragonfly's origins and mission concept
• Why Titan is unique and somewhat akin to the primordial Earth, perfect for exploring prebiotic chemistry
• Dragonfly's advanced science suite and autonomous flying capability
• Insights from the Cassini/Huygens missions and how they are shaping Dragonfly
• Navigation, flight strategy, and safety planning for Titan's harsh environment
• Power, heating, and longevity on Titan's freezing surface
• Titan's dune landscape, flying conditions, and analogs to Earth
• Big scientific questions: methane cycle, atmospheric mysteries, and potential surprises
• Mission timeline, lander design, and the innovative "fly-as-you-land" arrival approach

Most people don't think of spaceflight when talking about the United Nations, but the UN, through its Office of Outer Space Affairs, or UNOOSA, has been pivotal in securing agreements on space poilicy and behavioral norms. This week, we speak with Aarti Holla-Maini, the director of UNOOSA, and Dr. Rick Jenet, the executive director of Expanding Frontiers and the National Space Society's representative to the UN, about the importance of this office. It's a wide-ranging discussion of the intersection of international space efforts and the intersection with commercial space as we expand activities into Earth orbit, the moon, and beyond.

Headlines:

• SpaceX Crew-12 Launch Sends New Astronauts to the ISS
• Vast Joins Commercial Flights to the ISS, Prepares for Private Space Stations
• Axiom, Voyager, and Vast Face Off in Commercial LEO Station Race
• International Collaboration Ramps Up for Future of Space Policy

Main Topic: Inside UNOOSA—The United Nations Office for Outer Space Affairs

• Dr. Rick Janet Explains the Role of COPUOS and UNOOSA in Global Space Governance
• Aarti Holla-Maini Shares Her Path to Leading UNOOSA and Her Vision for Its Future
• Distinguishing UNOOSA (the office) from COPUOS (the committee)
• UNOOSA's Expanding Mission: Capacity Building, Disaster Response, Space Law, and Sustainability
• The Importance of Neutral Convening, Capacity Building, and Industry Input
• Growing Need for Space Sustainability, Debris Mitigation, and New Regulatory Focus
• Anticipating Lunar Activity: Resource Use, Transparency, and Non-Appropriation Principle
• Engaging Commercial Space Actors While Maintaining Member State Authority
• Megaconstellations: Building New Norms for Responsible Behavior in Orbit
• Future UNOOSA Goals: Coordinating Space Traffic, Centralizing Satellite Data Access, and Fostering Global Partnerships
