>Nimble Chinese satellite grabs hi-res images of US city in seconds: researchers
>In just 42 seconds, a small Chinese satellite captured images of a large area around a US city that would be sharp enough to identify a military vehicle on the street and tell what type of weapon it might be carrying, say scientists reporting on the breakthrough.
>The image, taken from an altitude of 500 kilometres (310 miles), had a resolution of 50 centimetres per pixel. The performance test over North America and other areas showed that the satellite could take images while its body was twisting at up to 10 degrees per second, a speed not seen on a satellite before.
