Buzz Aldrin tied the knot for the fourth time on his 93rd birthday.
The astronaut - who was part of the historic first-ever moon landing mission in 1969, alongside Neil Armstrong and Michael Collins - took to Twitter to share that he and Dr. Anca Faur, 63, had wed in a small private ceremony in Los Angeles.

We were joined in holy matrimony in a small private ceremony in Los Angeles and are as excited as eloping teenagers (sic)."
He also wrote: "Thank you for all of the Happy Birthday wishes and heartfelt goodwill! It means a lot and I hope to continue serving a greater cause for many more revolutions around the sun!!Onward and upward and best wishes to all of you as well!"
Dr Faur has worked at Buzz Aldrin Ventures LLC since 2019 and is currently Executive Vice President.
