Rosat Satellite May Crash The Earth

The world was gripped by the Nasa UARS satellite that fell back to Earth last Saturday and now there’s another that’s plummeting back from orbit. In late October or early November a Germany astronomy satellite called ROSAT- will plunge uncontrolled back to Earth. Experts believe that two dozen metal pieces from the bus-sized Nasa satellite fell over a 500-mile span in the Pacific Ocean. It began hitting the water southwest of Christmas Island.

The German ROSAT satellite was launched in 1990, 'died' in 1998 and weighs two and a half tonnes. The German space agency estimates that 30 pieces weighing less than two tons will survive re-entry. Debris may include sharp mirror shards. The German space agency puts the odds of somebody somewhere on Earth being hurt by its satellite at 1-in-2,000 — a slightly higher level of risk than was calculated for the Nasa satellite.Again, it seems certain that information on when or where the satellite might land will be scant.

Equipped with an 84cm mirror, it completed an X-ray survey of the sky, finding more than 150,000 objects. It followed up with targeted observations of interesting objects from galaxies, to neutron stars and even comets. It was switched off in 1999 and I calculate that it is now perhaps three weeks away from re-entry as its orbit decays, though it could survive into November.

NASA Old Satellite Falling On Earth

6 tons, but officials might never be able to pinpoint exactly where a massive NASA satellite plummeted to Earth.NASA space junk scientists think that all — or nearly all — of the dead, 20-year-old satellite safely plunged into the Pacific Ocean. But if their estimates are off, by only five minutes or so, pieces could have fallen on parts of northwestern North America.

NASA space junk scientists said Saturday they believe that all - or nearly all - of the parts of their 20-year-old decommissioned satellite safely plunged into the Pacific Ocean, likely missing land. But if their estimates are off, by only five minutes or so, fiery pieces could have fallen on parts of Northwestern North America.
No injuries or damage were reported on land, which NASA officials said was a good indication the satellite went into the ocean. NASA's earlier calculations had predicted that the former climate research satellite would fall over a 500-mile swath and could include land. Officials said the 35-foot satellite fell sometime between 11:23 p.m. EDT Friday and 1:09 a.m. EDT Saturday.

Top 10 Mysteries of Space

Since the beginning of life, man has looked to the stars with a sense of wonder. Between then and now, many advances have been made in the fields of astronomy, mathematics, and physics in an attempt to explain the things we see above, yet the more we believe we understand, the less we really seem to know. In something as big as the universe, there are bound to be unexplainable phenomena, and things we truly can’t grasp. The universe shows us how small we really are, and in a place so big, is it really plausible to believe that we are alone? And is there any reason someone might not want us to know? This is a list of what I believe to be some of the best mysteries and conspiracy theories of outer space.

10. Simulacrum in Eagle Nebula:


One of the strangest photos that has ever been taken of space is that of the Eagle Nebula. The photo itself is supposed to show the birth of a star from the gaseous clouds. However, when the photo was shown on CNN, hundreds of calls came in from people reporting they could see a face in the cloud. When the color of the photo was adjusted, a large human form seemed to appear within the cloud. Scientist have not been able to explain this phenomena.

09. Where did galaxies come from?

Science has only recently been able to explain where the stars and planets came from. Now, scientists have turned their attention to a much bigger mystery, where did galaxies come from? What is known is that galaxies are not scattered randomly throughout space, rather they are found in clusters, known as “super clusters”. Scientists have two main theories to attempt to explain galaxy formation. First, the gas left over from the big bang clustered together to form galaxies, in which stars and planets were born. Second is that gas from the big bang created stars and planets all over the universe, and they migrated through gravity into galaxies. Neither theory has been universally accepted yet.
