100ft Asteroid to Have Close Encounter With Earth

  100ft Asteroid to Have Close Encounter With Earth The asteroid will pass by Earth on October 12 at an estimated distance of 27,000 miles.The asteroid, named TC4, was discovered in 2012 and scientists have been tracking it ever since—until recently, it was thought TC4 could come within 4,200 miles from Earth’s surface.

FRANKFURT - An asteroid the size of a school bus flew remarkably near Earth on Thursday, providing scientists with an opportunity to test the warning systems that would kick in if a space collision was coming.

Asteroid 2012 TC4 came close -- passing Earth at a distance of only around 44,000 km (27,000 miles), which is nothing in Universe terms.

There was no actual risk of a hit, although the asteroid did come well inside the orbit of the Moon and that of some human-made satellites.

"Basically, we pretended that this is a 'critical' object with a high risk of impacting Earth ... and exercised our communication channels and used telescopes and radar systems for observations," Detlef Koschny of European Space Agency said in a blog post on the agency's website.

Evans banned over failed drug test

  Evans banned over failed drug test Dan Evans has been banned for one year following his positive test for cocaine in April, the International Tennis Federation has announced. Evans has been provisionally suspended since June 26 after failing the test in April at the Barcelona Open.The 27-year-old claimed at an emotional press conference in June he took the illegal substance out of competition and for reasons "completely unrelated to tennis".Following news of the ban, Evans said in a statement: "Following the announcement made from the ITF today I want to thank everyone who has supported me throughout this difficult period.

An asteroid the size of a school bus flew remarkably near Earth on Thursday, providing scientists with an opportunity to test the warning systems that would kick in if a space collision was coming.

The results were mixed.

Koschny said one big radar system in Puerto Rico did not work due to damage from Hurricane Maria but that another U.S. based radar system was used instead.

"This is exactly why we do this exercise – to not be surprised by these things," he said.

Radar images showed the asteroid was about 10 to 12 metres (yards) wide, roughly the size of an asteroid that exploded over Chelyabinsk, Russia in 2013, leaving more than 1,000 people injured by flying glass and debris.

Koschny said the ESA now needed to update its predictions for how close 2012 TC4 will come to Earth on its next flyby, which has so far been forecast for 2079.

First joint France-China satellite to study oceans .
France and China's space agencies unveiled their first joint satellite in Beijing Friday, which will be used to improve forecasting of ocean storms and cyclones .The satellite, named CFOSAT (China-France Oceanography Satellite), is due to be launched next year by China and will primarily be used to study wind and ocean wave patterns."In practical terms, it will be used to improve forecasts of strong storms, cyclones or waves for all coastal activities", Daniele Hauser, a French scientist working on the project, told AFP.
