Satellite hit by tiny space particle, suffers damage
European Space Agency's Copernicus Sentinel-1A, a radar imaging satellite launched in 2014, was hit by a millimetre-sized space particle on August 23, the agency confirmed on Wednesday. The impact created a 40-centimetre dent in the satellite's solar panel, causing a sudden small reduction in power. The particle was reportedly traveling at 40,000 kmph at the time of the collision.
