  • TWiS 197: Inside UNOOSA - The UN and Space

    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.

    • TWiS 196: Becoming Martian! - How Will Human Beings Evolve on Mars?

      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 University professor and researcher Scott Solomon joins us to explore these topics in depth, and to posit possible solutions.

      • TWiS 195: Remembering Apollo 1, Challenger, and Columbia - NASA's Week of Remembrance with Gerry Griffin

        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.

      • TWiS 194: COPs in Space! - Is the Outer Space Treaty Ready for the New Space Race?

        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!

        • TWiS 192: Space, 2026! - What's Coming in Spaceflight This Year

          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!

          • TWiS 191: Mars Throwback - The Pioneering Work of Dr. Robert Zubrin

            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!

          • TWiS 190: Holiday Special 2025 - A Look Back at 2025 in Space!

            It's our annual holiday special for 2025, in which we look back at the past year in space—its ups, its downs, its all-arounds. What a year it's been, and after all the challenges and hullabaloo, we're grateful in a post-Thanksgiving fashion to welcome Jared Isaacman, at last, as the new NASA Administrator. What he will do and how remains largely unknown, but we do believe he has the nation's interests at heart, and the man knows people are watching. But there are a lot of other stories and we've done our best to stuff as many as we can into this virtual Christmas space stocking! Please join us for this year-end roundup!

          • TWiS 189: Privatizing Orbit - The Pioneering Work of Jeffrey Manber

            This week, we talk with our favorite Newspace Buccaneer, Jeffrey Manber. When so many people were touting their private spaceflight dreams in the 1980s, Manber took the next enormous stride and actually made it happen. He formed the Office of Space Commerce within the US Department of Commerce at the invitation of the Reagan administration, forged the first commercial relations with the then-Soviet Union, bridged that into the post-USSR period, and was responsible for the first commercial spaceflight to the then-mothballed Soviet-era Mir space station with a crew that stayed there for 70 days. He then went on to develop a variety of commercial space enterprises, from the first commercial platform to release smallsats from the ISS to initiating the Bishop airlock that became part of the space station. He also started Nanoracks, the first privately developed and standardized satellite deployment mechanism to fly. Finally, he initiated Starlab, the private space station currently under development by Voyager Technologies and a consortium of aerospace companies. Join us for this very special episode with one of the key founders of NewSpace!

            Jared Isaacman, the billionaire entrepreneur, philanthropist, and private astronaut, took on Capitol Hill this week in his second confirmation hearing as President Trump's pick for NASA's next leader. Here's what it could mean, plus: A Russian cosmonaut got kicked off a SpaceX flight for allegedly trying to steal spacecraft secrets, China's 1st reusable rocket Zhuque-3 reached orbit, but crashed and burned (and exploded) during landing, and Russia accidentally wrecked the only launch pad it has for astronauts with Thanksgiving's new ISS crew launch.
