The evidence seized from Nowak's car that can now be shown to the jury includes maps to Shipman's house and steamy e-mails printed out from Oefelein's computer, which bolstered the police case that Nowak meant to hurt Shipman.
But the questions now may be: Will Nowak's case still go to trial, and are a plea bargain or reduced charges now possible?
Many of her former colleagues at NASA have told ABC News that they would like the case to go away. The prospect of a sensational trial, with cameras in the court and astronauts under oath testifying about love triangles is not the image the space agency wants to project.
Why Nowak, a highly accomplished Navy pilot, astronaut, mother of three and a woman described by colleagues as a good person, allegedly went to such extremes might remain a mystery if she does not go on trial.
Friends said Nowak is a very private person who just wants to get past this mess and move on with her life.
Both Nowak and Oefelein flew their one and only space shuttle missions in 2006. They were fired as astronauts by NASA in 2007 and are back on assignment with the Navy. They could face court martial charges once the civilian case against Nowak is resolved.
