Buzz Aldrin’s legacy extends far beyond his historic steps on the Moon. As a visionary engineer and space advocate, he pioneered the concept of the Aldrin Cycler, a revolutionary spacecraft trajectory that could enable safe, efficient, and cost-effective missions to Mars and beyond. In this episode, we explore how cycler spacecraft function, their potential to transform interplanetary travel, and why they remain a compelling solution for future space exploration. Join us as we celebrate the contributions of one of spaceflight’s greatest pioneers and examine the technology that could one day carry humanity to the Red Planet and beyond.
