Houston, we’ve had a problem: Retired astronaut Buzz Aldrin, 82, has officially divorced his third wife, Lois Driggs Cannon, and will fork over half his fortune as part of their settlement. Besides any heartache, Aldrin’s wife of 23 years must be over the moon: She’ll get half of a $475,000 bank account plus profits from her ex’s businesses, trademarks and stocks, according to reports. Aldrin further agreed to pay Cannon $9,500 a month plus 30 percent of his annual estimated $600,000-plus income. Cannon even keeps a 1988 Mercedes with the license plate “MOONGAL.” We revealed in September that the second man to walk on the moon was dating 30-years-younger Michelle Sucillon, whom Cannon called a “predator.” She added Aldrin was having a “kind of a midlife crisis in old age.”
