The Palm Beach Post reports that former astronaut Donald McMonagle, who once headed the space shuttle Atlantis, has put his riverfront house in Palm City, Fla., in Martin County (north of Palm Beach) for $1.3 million. Read about it here (Palm Beach Post). The paper reports that McMonagle has moved to Arizona, but provides no details on his new digs there. We will dish, however: public records show that on October 11, he paid $1.18 million for a place in Tucson. Also, public records show that in 2000, McMongle paid $500,000 for the place that he’s now selling.
