SpaceX Falcon 9 mission had people on social media split over a passenger on the space flight.
With over 10 million viewers of last Saturday's SpaceX, someone commented saying that a mouse hitched a ride on the shuttle. A video was then uploaded to show what looks like a tiny grey object moving around the engine nozzle of the Falcon 9.
People who watched the footage were split over what the actual object was. Some say it was a mouse, others thought it was a bead of water that condensed on foil.
Check out the video below, what do you think?!
