The collision between a US and Russian satellite some 500 miles above Siberia has raised concerns about the threat posed by orbital garbage.

A few minutes before 5 a.m. GMT on Wednesday, a US Iridium communications satellite and a defunct Russian military communications satellite smashed into each other, creating at least 600 pieces of debris that each could strike other satellites. It was the first time that two intact orbiting spacecraft have crashed into each other, say officials.
For its part, Iridium, whose network of 66 satellites – make that 65 – provides global coverage for handheld phones, denies that the collision is their fault, and says that any disruption in service will be brief and should be completely remedied by the end of the week.
According to the Voice of America, the official external broadcasting service of the US government, Russian officials say that debris from the collision pose no threat to the International Space Station or its three crewmembers, who are orbiting about 270 miles below the crash. The Pentagon says that it has not yet identified any threats to its own satellites, but added that tracking small objects in space is very difficult.
