Tracking implant

Tracking implants are a piece of technology created by the Blue aliens Destiny encountered in 2009.

Overview
The main function of the device is by tracking through great distances. They can be implanted inside a human body. In one instance, the device was implented next to the victim's heart, making the procedure to removing it difficult. They can also be easily damaged.

History
In 2009, Nicholas Rush, who was forcefully marooned on a barren planet by Colonel Everett Young, was abducted by the blue aliens. During his capture, he remembered the aliens planting the tracker inside his chest, next to his heart, with the purpose that if he escapes back to Destiny, they would track the ship, since they became interested in it before the Destiny Expedition arrived. Rush revealed this during the civilian mutiny of Destiny. After the military took back control of the ship, with the help of Lieutenant Tamara Johansen and Doctor Brightman, the device was successfully removed from Rush without serious injury. To destroy it, Lieutenant Matthew Scott smashed it with the butt of his sidearm.
