Look up folks..
A large US spy satellite is no longer under control and could leave orbit, thus crashing down on Earth in late February or March. But where it will crash is not known yet.
Experts are saying it will not do much difference to use a missile and blow up the satellite because that would cause debris which will still fall down to Earth.
Moreover, the experts are also worried that US secrets might be exposed if "other" people get access to the satellite when it comes down. The satellite contains beryllium. That's a metal used in defense and aerospace industries because it is light and very resistant to heat.
This is not the first time that an uncontrolled spacecraft is coming back to Earth. In 1979, the 78 ton Skylab, an abandoned space station, fell back to Earth, showering debris into the Indian Ocean and part of western Australia.
Could such "incidents" impact the Earth? What if the materials found on the crafts (some are hazardous, some might be 'contaminated' by other materials from space) mix up in nature, resulting in mutated wildlife? Watch out for Godzilla lol.. :)
