Ex-astronaut Lisa Nowak forced out of Navy

(CBS/AP) ORLANDO, Fla. - Lisa Nowak, the former astronaut who was banished from NASA after she confronted a romantic rival in a bizarre episode that involved an adult diaper, is being expelled from the Navy, according to officials.

Nowak will retire with an "other than honorable" discharge and her pay grade will be knocked down one rank, Assistant Secretary of Navy Juan Garcia said in a statement to The Associated Press Thursday.

Nowak's conduct "fell well short" of what is expected of Navy officers and she "demonstrated a complete disregard for the well-being of a fellow service member," Garcia said.

Nowak was accused of confronting Colleen Shipman in the parking lot of the Orlando International Airport in February 2007 after driving from Houston. Nowak had diapers in the car, but Nowak disputed that she wore the diapers. Shipman, an Air Force captain, had begun dating Nowak's love interest, former space shuttle pilot Bill Oefelein.

Police say Nowak sprayed pepper spray into Shipman's car. Nowak's attorney says the pepper spray never reached Shipman.

Nowak was sentenced in 2009 to a year of probation in the altercation after pleading guilty to burglary charges.

Since her dismissal from the astronaut corps, Nowak has been working at the Chief of Naval Air Training station in Corpus Christi, Texas. She will be demoted to commander when her retirement takes effect Sept. 1.

The "other than honorable" discharge may affect veterans' benefits for Nowak, who has been in the Navy for 20 years.
