The loss of Dr. Anca Faur at age 66 has touched many particularly because of the warmth of the relationship she shared with her husband, retired astronaut Buzz Aldrin. Their union was brief, yet deeply heartfelt: they married on January 20, 2023, and from the start their bond was described as equal parts personal and professional. When her passing was announced on October 28, 2025, Aldrin called her “the love of my life,” and noted that she “brought joy to everything we did together.” Born in Romania and later educated in the United States, Anca built a distinguished career as a chemical engineer and sustainable technology specialist before joining Aldrin’s enterprise, Buzz Aldrin Ventures LLC, as Executive Vice President. With a Ph.D. in chemical engineering from the University of Pittsburgh, she also served as treasurer of the California Hydrogen Business Council. Marriage to Buzz Aldrin: a partnership that moved bodies and soulsTheir story began at a professional event in December 2017; a few months later, they began dating, and by January 2023 they married in a private ceremony in Los Angeles, coinciding with Aldrin’s 93rd birthday. The announcement on social media spread quickly the official post announcing their wedding reached tens of thousands of reactions within days. What made their marriage resonate with people was less the age difference and more the genuine partnership they presented. Aldrin spoke of how they shared everyday moments meals, planning projects, simply watching the world go by and described Anca as someone with “brains, heart and courage.” She wasn’t just his spouse; she became a key part of his vision. In her role at Buzz Aldrin Ventures she supported his efforts in human space‑flight advocacy, and earlier in her career had worked on hydrogen fuel cell and sustainable tech projects fields that dovetail with Aldrin’s own interest in the future of space travel. In October 2025 the news broke that Anca had died peacefully, with her husband and her son by her side. The tribute from Aldrin simple yet powerful: “I will miss her dearly.” Anca Faur’s story is one of intellect, achievement and heartfelt connection. While her time as Mrs. Aldrin was short, the impact of their shared path was profound. She brought decades of professional accomplishment into a marriage grounded in affection, respect and shared purpose. For Buzz Aldrin, she was more than a companion: she was a teammate in every sense. Her passing leaves a void not just in his life, but in the story of two people who despite different backgrounds and an age gap found genuine joy in each other’s company.
