A  large US spy satellite has lost power and is 
expected to crash back to Earth in late February or March. The defunct spy apparatus which 
is believed an experimental imagery satellite launched in 2006 and now is de-orbiting has the size of a bus, impending a threat of hitting anywhere on the Earth. As it still contains unfinished highly toxic
 hydrazine fuel, the environmental concerns may be raised after it plunges to the Earth out of control. 
TimesOnline speculated the US government could destroy the unmaneuverable satellite by opting to employ America’s new laser weapons for use against incoming missiles, which 
are now being tested on board a modified Boeing jumbo jet.
