The navigation system has been fixed and the ship has been rerouted back to the original destination of Osiron. Here's what you learned:
The Navigation Log shows that while the ship was sabotaged, it had been heading to the moon Yetho.
The last message sent on the Communication Console read: "Confirmed. There are survivors from Zena on Yetho. - The Viper"
Tai (the Hacker) changed course to Yetho and sabotaged the navigation system.
