Please review/download Dan’s PDF document which you can find at www.thespaceshow.com/show/18-may-2025/broadcast-4374-dan-adamo. We welcomed Dan Adamo back to the program to discuss his recent work, presented to AIAA, on human spaceflight travel between Earth-Mars waypoints. The PDF of Dan’s presentation is available on the blog page for this episode. We began by reviewing key definitions and terminology before launching into a slide-by-slide discussion. Part 1 concludes with Slide 5. For full context, please open the PDF and follow along. It will also be essential for understanding Part 2 of this discussion, airing next week.In this segment, Dan defined many of the terms and concepts introduced in his presentation on Interplanetary Synodic-Resonant Waypoints. He also drew comparisons to the mature U.S. airline industry, suggesting how its development might parallel a future interplanetary transportation system though no such system exists in any form whatsoever today. Dan emphasized that his work is speculative—an important note to keep in mind, especially during our discussion of mission timelines and travel durations between Earth and Mars.Starship played a major role in the conversation, with some additional references to SLS, Orion, and the Gateway. Although we briefly touched on topics such as the Moon, lunar habitats, and development, the primary focus remained on the Earth-Mars Synodic-Resonant Waypoints.Dan responded to several listener calls and email questions throughout the show. While the subject matter was technical, we made a concerted effort to ensure that Dan explained concepts in accessible, layman’s terms.Dan invited further listener questions, especially from those catching the archived version of the show. He provided instructions for how to contact him directly via email for those preferring that method over blog posting. Throughout the discussion, he highlighted how his proposal could serve as a conceptual roadmap for future interplanetary travel—and he expressed hope that it might one day inform serious Earth-Mars mission planning.Late in the discussion, Dan was asked about waypoints for travel from Earth to Europa in the Jovian system—don’t miss Dan’s fascinating response to that question.Be sure to tune in for Part 2 of this program on 25 May 2025 at 12:00 PM PDT, using your usual method for accessing Space Show episodes.Thank you for listening!Special thanks to our sponsors:Northrup Grumman, American Institute of Aeronautics and Astronautics, Helix Space in Luxembourg, Celestis Memorial Spaceflights, Astrox Corporation, Dr. Haym Benaroya of Rutgers University, The Space Settlement Progress Blog by John Jossy, The Atlantis Project, and Artless EntertainmentOur Toll Free Line for Live Broadcasts: 1-866-687-7223For realtime program participation, email Dr. Space at: [email protected] Space Show is a non-profit 501C3 through its parent, One Giant Leap Foundation, Inc.
