Orlando, Florida (CNN)  -- A former astronaut who was accused of assaulting a romantic rival in the parking lot of the Orlando airport will avoid prison after pleading guilty to lesser charges as part of a plea agreement. Citing Lisa Marie Nowak's lack of a criminal history, Orange County Circuit Judge Marc Lubet sentenced her to a year of probation. She was given credit for the two days she served in the county jail after her arrest. Nowak, 46, must also perform 50 hours of community service and have no contact with the victim in the case, former Air Force Capt. Colleen Shipman.
