"China's Spy Balloon Program Expands with New Solar-Powered Radar Technology"

A Chinese spy balloon shot down by the US in February carried solar panels that could generate enough electricity to power a type of radar that can generate images at night and through clouds, according to leaked US intelligence documents. The balloon caused an uproar in Washington and damaged US-China ties when it flew over the US in January and February. It was downed off the coast of South Carolina on Feb. 4 by a missile fired from a US Air Force jet.
