    E1 | Seeking beyond the rocket equation - the prospect of space elevators
    2021/01/31
    This episode has at its core the implications of Tsiolkovsky’s rocket equation, which figures the hard limits of rocket-based payload transportation to Earth’s orbit. Furthermore, rockets are expensive, up to failure, risky and carry too little payload. Making rockets more efficient reminds analogically of Henry Ford’s classic: “If I had asked people what they wanted, they would have said faster horses”. One of the non-rocket approaches to get a fast, cheap, safe and repeatable transport to orbit is the Space Elevator concept which we are going to cover in the episode with our guest, the amazing Josh Bernard-Cooper, a University of St Andrews Physics and Philosophy student, International Space University alumni and Research Assistant at the International Space Elevator Consortium.

    E2 | A Space for Humanity - Ethics and Governance for Living together in the Space Age
    2021/03/09
    In this intense episode we dig into the main issues preventing international and intercultural collaboration here on Earth which will prevent us from becoming a prosperous, inclusive, and peaceful multi-planetary species. In search of solutions, we begin with the power of law and then blast over to the ongoing space race between private actors and developing countries, uncovering who is really in power. Shattering conventional narratives along the way, we explore a supracultural code of space ethics, a way to ensure that space and its benefits for life on Earth remain accessible for all of humanity. Our guest taking us on this journey of discovery is the bleeding-edge scientist Timiebi Aganaba-Jeanty, Professor of Space and Society at the School for the Future of Innovation in Society at the University of Arizona.

    E5 | Space Commerce - The ecstasy of gold
    2021/04/15
    In this episode, we’ll be diving right into the dynamics of the space sector, space commerce, space business, space industry, space market, and the fundamental forces driving their development. It’s a great pleasure to welcome Matthew Weinzierl, an associate Professor in the Business, Government, and the International Economy Unit at Harvard Business School. Matthew has worked for McKinsey & Company, and the US government as an economist on The White House Council of Economic Advisors. While much of Professor Weinzierl’s early research focused on the optimal design of economic policy, in particular taxation, he has recently launched an array of projects focused on the commercialization of the space sector and its economic implications. Matthew, together with his Harvard Business School team, have published multiple case studies just this past year: on Space X and Economies of Scale along with Made in Space and the business of In-Space Manufacturing, all of this along with an article emphatically proclaiming: “The Commercial Space Age is Here” in the Harvard Business Review.

    In this episode, we talk about the rise of Space Marketplaces and how the Satsearch Product Knowledge Graph helps solve problems for marketplace users. We ask, what kind of Acquisition Loops work in the space sector, how does their Experiment Framework look like, and should space marketplaces scale vertically or horizontally? We talk about unit economics, defensibility, and how Satsearch bootstrapped its way forward with the support of the ESA Business Incubation Center. Our guest is Narayan Prasad, co-founder, and COO of Satsearch, a global marketplace for the space industry, incubated by the European Space Agency.

    E8 | The breakthrough of gram scale space crafts
    2021/06/04
    In this episode we will explore the bleeding edge of satellite and satellite constellation miniaturization. These awe inspiring craft commonly known as Chipsats, Wafersats, Sprites, Monarchs, Kicksats, Starchips, or even just “Smart Dust” are facilitating the rapid miniaturization of space craft following an exponential trajectory stipulated by Moore's Law, no doubt enabling new incredible possibilities and discoveries just around the corner. We talk about the unique physics and associated challenges that these low-mass vehicles face in space, how incredible engineering is overcoming them, and how the Breakthrough Starshot project will tackle the very difficult problem of sending a spacecraft interstellar to Proxima b. Our guest today is Professor Zachary Manchester, who studied physics and aerospace engineering at Cornell University earning his BS and PHD respectively. Zac undertook his Postdoc at Harvard and became Assistant Professor at Stanford University, and later at Carnegie Mellon University where he now heads the Robotic Exploration Lab. He received critical acclaim for his Kickstarter.com crowdfunded Kicksat project - deploying an armada of chipsats in LEO and has published together with Mason Peck and Avi Loeb and is member of the Breakthrough Starshot Research team, who are working on an interstellar spacecraft mission to Proxima-b.
