It isn't ours says the US, Russia and Germany. A mysterious metal ball, two hemispheres welded together, has fallen to earth in Namibia. The "ball" is 35 centimeters wide and cut a groove in the ground on impact 33 centimeters deep and 3.8 meters wide. The hollow sphere is not dangerous - it isn't an explosive devise. There were two recent orbital crises with satellites crashing to the ground: NASA's Upper Atmosphere Research Satellite and Germany's Roentgen Satellite. The mystery object is not part of any of these. The Phobos-Grunt Mars Probe made in Russia will also soon come down. There is the possibility that it could be from a satellite much older, something that has been orbiting for a long time. If this is the case, ownership of the space debris may never be known because no country wants it known that satellite parts can fall at random from the sky. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http:
