This Week in Space 191

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!
