In February 2024, a Chinese observation balloon was detected in the skies above the US. Since then, other balloons have been discovered around the world. Their high speed makes them a difficult target for satellites to observe. Researchers have developed a new technique to detect and resolve moving objects in satellite images, such as weather balloons, reconnaissance airships, and unidentified aerial phenomena (UAPs).
