A huge 18-ton chunk of China's Long March space rocket is now set to land in the Pacific - but predictions are changing by the minute as it hurtles towards Earth. The latest estimates project re-entry will take place early on Sunday morning, with most agencies predicting it will emerge between 2am and 4am UK time. The Aerospace Corporation says the rocket will arrive at around 2.11am UTC, with the European Union’s Space Surveillance and Tracking team estimating 2.30am. Space-Track agrees, saying the Long March fragment should arrive within hours. The rocket's path is too unpredictable to pinpoint exactly where it will crash, but recent forecasts have suggested it may fall in the Pacific Ocean.
