Buzz Aldrin is suing his children, who say they are trying to protect the space icon

Two of Buzz Aldrin's children were worried about him. The world-famous astronaut was getting older, showing "increased confusion and memory loss," Andy and Jan Aldrin, his son and daughter, said in a statement. And so they sought to protect him from the "debilitating effects of his worsening condition," they said, seeking a court order that would install them as guardians, able to oversee his finances and fend off outsiders seeking to profit off his name and image.
