A Maryland rocket scientist has been charged with a third count of attempted espionage for allegedly including details on a classified Navy satellite program among the items he’s accused of passing to an undercover FBI agent posing as an Israeli spy.

Stewart Nozette also allegedly told the “spy” that he had been storing classified information in a California safe deposit box since the 1990s, according to court documents filed in the District’s federal court Wednesday. His attorney John Kiyonaga declined to comment.
