Many of you may have noticed this story in the news over the last week... "A five tonne, 20-year-old satellite has fallen out of orbit and is expected to crash somewhere on Earth on or around 24 September, according to Nasa. Nasa says the risk to life from the UARS - Upper Atmosphere Research Satellite - is just 1 in 3,200. It could land anywhere between 57 degrees north and 57 degrees south of the equator - most of the populated world. However, most of the satellite will break or burn up before reaching Earth. Scientists have identified 26 separate pieces that could survive the fall through the earth's atmosphere, and debris could rain across an area 400-500km (250-310 miles) wide. Experts claim that the satellite was accidentally knocked out of orbit by an Evian water bottle launched from Earth on November 20th, 2010. The bottle is believed to have survived the impact, and is due to return to Earth at approximately 16:00 tomorrow afternoon. Nasa said scientists would only be able to make more accurate predictions about where the satellite might land two hours before it enters the Earth's atmosphere." http://www.bbc.co.uk/news/world-us-canada-14952001 Don't forget your brolly folks!
That one's already come down. There's another one, though: http://www.dailymail.co.uk/sciencet...satellite-crash-land-weeks-time.html?ITO=1490
