ORLANDO, Fla. -- The trial of a former astronaut accused of attacking a romantic rival has been set for early fall, a spokeswoman for Florida's circuit court said Tuesday.

Trial for Lisa Nowak, 43, will begin Sept. 24 in an Orlando courtroom with Judge Marc Lubert presiding.

Nowak has pleaded not guilty to charges of attempted kidnapping, burglary with assault and battery.

She will have a status hearing June 29 and a pretrial conference July 17.

Nowak's attorney, Donald Lykkebak, had requested more time to evaluate his client's mental health.

Nowak was arrested in February after police said she drove from Houston to Florida -- wearing a diaper so she would not have to stop -- to confront Air Force Capt. Colleen Shipman.

Authorities have said Nowak had an affair with Shipman's boyfriend, Bill Oefelein.

Nowak pepper-sprayed Shipman through a partially lowered car window, an arrest affidavit said.

Nowak's trial had previously been scheduled to begin in July.
