NASA's getting ready to launch a Raven into space.

FOX's Monica Rix explains:

This weekend, NASA will launch a little slice of Westoros into space when a Space-X Falcon 9 rocket carries a "three-eyed" Raven technology module to the international space station.

Once it gets there, Raven will use its sensors to collect information from spacecraft coming and going from the ISS so that ultimately NASA can develop better navigation technology.

Experts say it's crucial for future missions because it could make re-fueling and servicing satellites easier. NASA hopes Raven's running by 2020.
