Close friends reveal that Anca Faur had been fighting a rare and aggressive form of cancer. It was a battle she faced privately before succumbing to the illness. Cancer’s impact on her health was significant, and despite efforts by medical professionals, the disease progressed rapidly. 

Faur’s health had been deteriorating in her final days despite efforts and treatment. The cancer’s progression was rapid, and “even a month ago we were optimistic,” Charles, her close friend, said. However, the specific type of cancer has not been publicly disclosed. “She died peacefully, but there was nothing that could be done about her aggressive cancer,” the friend added. Her passing underlines how even accomplished individuals can face stealthy, serious health battles.

A study published in The Lancet Oncology highlights that aggressive cancers require prompt diagnosis paired with multidisciplinary treatment approaches. The study notes that survival rates improve significantly with early detection and personalised therapies, but aggressive variants often present late and progress fastest.

Who Was Anca Faur?

Anca Faur was not just a spouse to a space legend, but she was a highly accomplished scientist and executive. She held a PhD in chemical engineering from the University of Pittsburgh and served as Executive Vice President of Buzz Aldrin Ventures LLC, as well as treasurer for the California Hydrogen Business Council. 

Aldrin, who became the second person to walk on the Moon during the Apollo 11 mission, once said of her, “When I met Anca, I instantly recognised that here was a woman who is the whole Wizard of Oz package: Brains. Heart. Courage.” They had shared a close bond professionally and personally, and her loss leaves a deep gap in his life and in their shared community of space and science advocacy.
