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!

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!

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 is widely accepted that over time, humanity will need to expand its presence into the solar system. What are the challenges? Well, space and our nearby worlds have proved to be a much greater challenge than we had long thought. While the rigors of zero-g have been well researched on the International Space Station, the challenges of living in lower gravity, such as that found on the moon and Mars, has not yet been explored. And human reproduction in space, along with genetic challenges, is a complete unknown. Rice Univeristy professor and researcher Scott Solomon joins us to explore these topics in depth, and to posit possible solutions.

Headlines:

• Artemis 2 Moon Launch Faces More Delays Due to Hydrogen Leaks
• Perseverance Rover on Mars Completes First Fully AI-Driven Journey
• Study Warns of Urgent Need to Research Human Reproduction in Space

Main Topic: Becoming Martian – What It Would Take for Humans to Thrive on Mars

• Biological impacts of space and Martian environments on the human body
• Gaps in research about human reproduction, growth, and development in space and partial gravity
• Ethical, social, and medical challenges of having children beyond Earth
• The complexities of transplanting Earth's ecosystems, microbiomes, and the risk of disruptive species
• Evolutionary changes and the likely divergence of human populations living long-term off-Earth
• Considerations around modifying humans versus modifying extraterrestrial environments
• Infectious disease threats and dwindling biological immunity for space settlers
• Psychological, cultural, and population dynamics for future interplanetary communities

This month marks a bitter annual anniversary for NASA. On February 1, 1967, the crew of Apollo 1 was killed in a horrific fire on the pad in Florida. Years later, as the space shuttle Challenger ascended on February 28, 1986, it was destroyed mid-flight with a loss of seven crewmembers. Finally, on February 1, 2003, the shuttle Columbia was lost during reentry, again with a crew of seven. This episode is a remembrance of these tragic events with Gerry Griffin, former Apollo Flight Director and Director of the Johnson Space Center among his many other roles with NASA and beyond. Gerry brings a personal touch to these events, describing the experiences first-hand and lessons learned. Please join us for this very special episode.

The Outer Space Treaty of 1967, which was intended to regulate activities in space, is hard to enforce and woefully out of date. New nations and private actors are entering the spaceflight arena, and an updated mechanism with a bit more teeth is needed. Our guest, Ely Sandler, a Fellow at the Harvard Kennedy School, has put forward the idea of using COPs—not the kind in uniform, but a Conference of Parties—as a less-formal gathering of spacefaring (and space-ambitious) entities, to discuss future treaties, agreements, and enforcement mechanisms, eventually leading to new treaties. These would be similar to the annual climate COP that has provided useful discourse on climate change. A space COP would address responsibility for and control of orbital assets, land and resource use on the Moon, Mars, and asteroids; and possibly limits to the militarization of space. Join us for a fascinating discussion!

2026 promises to be the most exciting year in the new space age yet! Shining bright is the prospect of an Artemis II launch to send astronauts around the moon for the first time since 1972, as early as February. We've already seen news about a medical incident on the International Space Station that will force a crew to return to Earth early, but NASA says this won't affect the Artemis launch. On other news, NASA's budget seems on track to be passed at near 2025 levels, China is preparing to send a robot to the south lunar pole, SpaceX plans robust tests of Starship this year—and hopefully refinement of their lander for Artemis III, Boeing will fly Starliner again (uncrewed), Mars Sample Return is poised to be scuttled, and all this under the leadership of a new—and apparently quite capable—NASA administrator, Jared Isaacman. Join us for an in-depth look at what's coming in 2026!

Headlines:

• Medical evacuation planned for ISS astronauts due to health concerns
• NASA Chief Jared Isaacman leads first big press conference amid ISS medical incident
• Artemis 2 lunar mission remains on track for February launch
• Orion spacecraft heat shield faces scrutiny ahead of crewed flight
• NASA budget nearly secured—Congress backs full funding for 2026
• Mars Sample Return project faces likely cancellation
• SpaceX Starship gears up for crucial orbital and refueling tests
• Blue Origin's Blue Moon lunar lander launch delayed, competition heats up
• China's lunar, asteroid, and orbital missions ramp up for 2026
• Boeing Starliner and Sierra Space Dream Chaser schedule ISS cargo missions
• New moon landers, asteroid missions, and global crewed capsule tests coming in 2026
• NASA's Roman Space Telescope possibly launching this year

One of our favorite interviews of 2025 was with Dr. Robert Zubrin, founder of the Mars Society and the mind behind Mars Direct, a streamlined approach to reaching the Red Planet with human beings that was later largely adopted by NASA in their mission designs. It's a fascinating story about a man who continually swam upstream against strong currents of the aerospace establishment. His seminal book, "The Case for Mars," has enjoyed multiple reprints and influenced millions. Join us for this encore of an informative and forward-looking episode!
