The U.S. is tracking a small, high-altitude balloon that is drifting across the country but poses no threat to national security, U.S. officials and the military said Friday.

CBS News first reported that the military was tracking the balloon as it traversed the Western U.S. earlier in the day. NORAD, the military command responsible for air defense over the U.S. and Canada, later confirmed it had detected the object and said it was floating between 43,000 and 45,000 feet. Its presence prompted enough concern that the command sent aircraft to investigate.

“The balloon was intercepted by NORAD fighters over Utah, who determined it was not maneuverable and did not present a threat to national security. NORAD will continue to track and monitor the balloon,” NORAD said in a statement. “The FAA also determined the balloon posed no hazard to flight safety.”

One U.S. official told CBS News the balloon was expected to be over Georgia by Friday night. The official said the balloon appeared to be made of Mylar and had a small cube-shaped box, about two feet long on each side, hanging below it. Its origins and purpose remain unknown.

The developments come one year after tensions between the U.S. and China ratcheted to new heights after a Chinese balloon carrying sophisticated spying equipment flew over the continental U.S. for several days.

“The intelligence community’s current assessment is that these three objects were mostly balloons tied to private companies, recreation or research institutions studying weather or conducting other scientific research,” the president said.
