About the size of a bus
Damn thing weighs 13,000 lbs and is 35 feet long, 15 feet in diameter.
Chances are that it will fall in an ocean.
Further updates are expected 12, six and two hours before re-entry. The space agency anticipates that 26 potentially hazardous parts, weighing a total of 1170 pounds, could remain intact and hit the Earth. The debris will spread along an estimated 500-mile corridor of the Earth’s surface. Among the parts expected to survive the fiery re-entry are four titanium fuel tanks, four steel flywheel rims and an aluminium structure that alone weighs 348 lbs. Depending on their size and shape, the components will strike at speeds of between 55mph (90km/h) and 240mph (385km/h).
