Six tonne satellite tumbling to earth
A six tonne satellite has fallen out of orbit and is expected to crash somewhere on Earth, according to Nasa.
Nasa says the risk to life from the Upper Atmosphere Research Satellite (UARS) is just 1 in 3,200.
However, most of the satellite will break or burn up before reaching Earth.
