US and Russian satellites have accidentally collided orbiting in space over Siberia. This is very first such accident.

American satellite which belongs to US company Iridium has been collided with Russian inactive satellite.

BBC reported that this was first time two man made spacecrafts collided during orbiting around Earth.

NASA reported that impact produced massive clouds of remains of collided satellites.

Scientists are concerned about possible spreading of debris near the ISS station which is orbiting 435 km bellow the course of collision of two satellites.

Washington Post reported that NASA confirmed that there is very small risk within acceptable limits of possible damage that debris could cause to ISS.

The Iridium satellite weighed 1,235 pounds, and the Russian craft nearly a ton.

NASA said that earlier there were four other cases of accidental collision of space objects but those included minor parts of spent rockets or very small satellites.
