Another Satellite's Re-entry (ROSAT)

روسات هو قمر صناعي لقياس الأشعة السينية الآتية من بعض الأجرام السماوية. بلغ وزن القمر الصناعي بمعداته 2426 كيلوجرام وهو يعتبر أكبر قمرا صناعيا ألمانيا وزنا، وتكلف نحو 560 مليون مارك ألماني.

ROSAT re-entry

The defunct German Roentgen Satellite (ROSAT) is coming back to planet Earth -
sometime in late October or early November. The X-ray space observatory is less
than half the weight (2.4-tons) of the fallen UARS, but has an orbit that
ranges from latitudes of 53 degrees north and south, putting it in a position
where it can threaten a wide region that stretches from Canada to South
America. And while much of the spacecraft will disintegrate during it’s rapid

ROSAT may not be larger, but this satellite will be one of the most dangerous satellites, giving Earth a 1 in 2000 chance of someone being hit. Anyone hit by this one would certainly not feel good and here is what makes this so dangerous.

ROSAT is Germany's Space Telescope. The satellite scope has mirrors that were designed and built for extreme heat. These mirrors will break, but most of it will be intact when it hits the Earth. The mirrors will act like a giant blade raining many pieces of glass onto a stretch of over 500 km.
UARS was dangerous due to the heavier pieces, but ROSAT will be dangerous because it will be like throwing knives out of an airplane and not knowing where thousands of these knives will land.

ROSAT simply is going to be one to watch over the next month. Recent solar storm activity is lessening the orbit day by day and the Sun will belch x-class flares toward the planet this week. This prompts the conclusion this satellite will come in next month, earlier than the later month forecast
