According to NASA, if a giant asteroid was on a collision course with Earth, we’d all be pretty much done for.
The agency just completed a weeklong simulation looking at various scenarios – and concluded that we wouldn’t be able to stop an asteroid using current technology – even with six months of advance notice.
Evacuating the impact area would be our only option – and NASA says governments are “dreadfully unprepared” for such a scenario. However, the agency is working on new technology called DART – Double Asteroid Redirection Test – that could potentially redirect an asteroid’s orbit to prevent a threat to Earth.
There is currently no technology on Earth that could stop a massive asteroid from wiping out Europe, according to a simulations carried out by leading space agencies. The week-long exercise led by Nasa concluded that catastrophe would be unavoidable, even given six months to prepare.
