What happens when the traditional path to becoming an astronaut closes before you even get the chance to prove yourself? For Dr. Dirk Raiser, it meant finding another way forward. Dirk is a German experimental physicist, optical-instrumentation specialist, analog astronaut, commercial astronaut candidate, and founder of Razzor Tech, a startup developing spacesuits and mobility systems for astronaut training. In his scientific career, he works with advanced lasers and X-ray instrumentation at European XFEL, helping researchers observe incredibly fast changes in matter. Outside the laboratory, he has commanded an analog mission at LunAres Research Station, supported the Austrian Space Forum’s AMADEE-24 Mars simulation in Armenia, and served as engineering officer during the World’s Biggest Analog mission at MENA in Wadi Rum, Jordan. He is also a father of five whose pursuit of space has grown alongside, rather than in opposition to, his family. In this conversation, Dirk shares how a childhood fascination with rainbows and light led him into experimental physics, why the ESA astronaut selection process became a turning point, and how he began building a second professional path devoted to human spaceflight. We explore the role analog missions play in preparing people for Mars, the enormous amount of work hidden behind every successful simulation, and why the future of space exploration depends on thousands of people whose names may never appear above the credits. We also discuss Razzor Tech’s development of modular analog EVA suits, portable life-support systems, neutral-buoyancy training equipment, and future mobility technologies for the Moon and Mars. Along the way, Dirk reflects on commercial astronaut training, stepping outside his comfort zone, preserving wonder through scientific understanding, balancing ambition with parenthood, and why he would still accept a one-way ticket to Mars. This is a conversation about rejection, reinvention, curiosity, and refusing to believe that there is only one route to the stars. ~ Inside the MENA Analog with Salam Abualhayjaa: https://podcasts.apple.com/us/podcast/inside-the-mena-analog-mission-with-salam-abualhayjaa/id1777937758?i=1000759991093 Inside the World's Biggest Analog with Jas Purewal: https://podcasts.apple.com/us/podcast/inside-the-worlds-biggest-analog-with-jas-purewal/id1777937758?i=1000747831688 ~ A huge thank you to Dirk for taking the time to join me today and share his incredible experiences and perspective. And of course, thank you to Nick Thorburn for the stellar theme music, Ceci Giglio for the incredible graphics, Jero Squartini for the amazing animations, to RDan, Leila, Inka, and Carl for admining the Facebook group, and to my family for supporting this project—even when our conversations somehow end up 25 kilometers below the Martian “sea level.”
