TWiS 173: The Return of the Malik - The Wild Proposals on NASA's Table

If we're ever to make Mars a second home, we have some serious housekeeping to do... as in a total renovation. The Red Planet has little atmosphere, no radiation shielding, and some seriously toxic soil. How can we make it more Earthlike... and should we? Dr. Erika Alden DeBenedictis joins us to discuss how terraforming might work, how it could be done in decades instead of millennia, and the questions surrounding the ethics of changing another planet to suit humanity's needs. We say it's a trailer park of a planet, but the best bet for human expansion. Dr. Rick Jenet is this week's co-host. Join us for the conversation!
 

 
Headlines:

 
 • NASA aims to place a nuclear reactor on the moon by 2030, competing with China's similar plans for the Moon.
 
 • NASA's planned commercial space stations are facing delays. As ISS retirement nears, the U.S. risks losing its foothold in low-Earth orbit within the coming years. 
 
 • SpaceX hits 100 launches in 2025, dominating global orbital launch activity and enabling rapid rocket reuse.
 

Main Topic: High-Speed Terraforming of Mars

 
 • Guest Dr. Erika Alden DeBenedictis shares new, biotech-driven concepts for terraforming Mars much faster than traditional proposals.
 
 • Dr. DeBenedictis shares a modern understanding of Mars' past and present environment, including radiation, toxic perchlorate-laced soil, and thin atmosphere.
 
 • Discussion on the importance and challenges of Mars Sample Return for accurate soil and resource analysis.
 
 • Modern synthetic biology as a tool for creating microbes tailored for Martian soil and future terraforming.
 
 • A step-by-step outline by Dr. DeBenedictis on building a breathable Mars atmosphere via engineered photosynthetic microbes, engineered atmospheric warming, and greenhouse construction.

TWiS 172: Earth on Mars - Terraforming the Red Planet

The United Nations has mediated conflicts since its founding in 1945. That domain of involvement extended into space in 1967 with the Outer Space Treaty. Today, their role is increasingly active with more and more nations entering space and the private sector getting into the game. The US's space-related branches, UNOOSA (the UN Office of Outer Space Affairs) and COPUOUS (UN Committee on the Peaceful Uses of Outer Space), are busy. Many years ago, the National Space Society gained permanent UN observer status, which is much less passive than the name sounds. The organization has addressed the committees on more than one occasion and is working to influence the policy for space flight positively. Dr. Rick Jenet has been instrumental in these efforts and joins us in explaining the landscape of newspace, international space efforts, and the organization's future initiatives.

Headline

 
 • Space Shuttle Discovery Controversy: Rod and Isaac discuss the proposed $85 million move of the Space Shuttle Discovery from the Smithsonian to Houston, plan that faces obstacles from the Smithsonian, which holds the rights to the shuttle.
 

Main Topic: UNOOSA & Dr. Rick Jenet

 
 • The National Space Society's UN Observer Status: Dr. Jenet explains that the NSS gained permanent observer status at the UN in 2001. The NSS uses this privilege to inform delegates by providing research and presentations.
 
 • UNOOSA and COPUOS Explained: Dr. Jenet clarifies that UNOOSA organizes the Committee on Peaceful Uses of Outer Space (COPUOS). While UNOOSA maintains a registry of space objects, COPUOS is the body of 104 member states that develops legal frameworks.
 
 • Outer Space Treaty of 1967: Dr. Jenet talks about the Outer Space Treaty, a global treaty dating back to the Cold War era that governs how state actors behave in space. He that the treaty's language on property ownership is being re-examined due to the rise of commercial space activities.
 
 • Space Traffic Management and Orbital Debris: Dr. Jenet highlights that discussions on space traffic management and orbital debris are in their early stages. These discussions focus on basic tenets like coordination and information sharing.
 
 • Lunar Activities and Resource Utilization: The development of policies for lunar exploration and resource extraction is also an area of new activity. UNOOSA's "Action Team for Lunar Activities Consultation," with co-chairs from Romania and Pakistan, coordinates the future of humanity's return to the moon by aligning different national initiatives.
 
 • The "Regulation Sandbox" Concept: Dr. Jenet discusses the "regulation sandbox" concept, where existing regulations for an area with commercial potential, for example a lunar ice deposit, are set aside for a limited time to allow a new set of rules to be tested. This concept could be applied more boradly to space launch or ISRU.
 
 • Why the Public Should Care: Dr. Jenet emphasizes that the public should care about these efforts because these high-level discussions will lead to international laws governing the behavior of all actors in space, including private companies and entrepreneurs. Early awareness of these frameworks will be less painful for startups later on.

TWiS 171: What's an UNOOSA? - Rick Jenet, the National Space Society, and the UN

Powering spacecraft, especially out in the dark, cold outer solar system, is a huge challenge. There are limits to how large solar panels can be, and they are not very efficient in the weak sunlight beyond Mars. For decades, choice flagship NASA missions have used RTGs--radioisotope thermoelectric generators--to fill this need. From the experiments on the Apollo missions to the Viking Mars landers, Galileo to Jupiter, Cassini to Saturn, and the twin Voyagers, RTGs have provided decades of power for space exploration. From Plutonium to Americium, nuclear elements provide years and years of heat that can be converted into electricity. Dr. Rob O'Brien is the Director of the Center for Space Nuclear Research for the Universities Space Research Association and has specialized in RTGs for decades. It's a fascinating dive into atomic space batteries!

TWiS 170: Atomic Space Batteries! - Dr. Robert O'Brien of USRA

Sixty years ago this week, the Mariner 4 probe sped past Mars, the first to succeed in this then-brash undertaking. The technology was unbelievably primitive, yet effective, sending back 22 low-resolution video frames of the Red Planet. On that day, the wee hours of July 15 at JPL in Pasadena, the Mars of the romantics died. What had long been viewed as a slightly colder, somewhat drier, near-twin of Earth ended up having just a trace of an atmosphere and looked more like the moon--bone dry and pummelled by craters. Rob Manning, JPL's Chief Engineer Emeritus, joins us for this look back at that mission and the first images returned of another planet from space.
