In a recent development, a high-altitude balloon suspected to be of Chinese origin was seen drifting across the US. Although China confirmed the balloon's belonging to the country, it was stated to be used for scientific research purposes. The massive structure, measuring the size of two to three school buses and equipped with surveillance equipment, has drawn concern from the US Defense Department and NASA, who are collaborating to assess the potential impact in case the balloon were to be shot down. China attributed its presence in US airspace to 'force majeure' and has communicated with the US regarding the situation. The balloon's trajectory remains uncertain, as it is at the mercy of the jet stream. Meanwhile, Secretary of State Antony Blinken's planned diplomatic trip to China has been postponed due to the balloon's presence.
