Humanity Is DOOMED If Asteroid Is On Collision Course With 'Unprepared' Earth, Warns Nasa

A NASA scientist has sent out a startling asteroid warning, stating that Earth is doomed if there is a collision as we are massively unprepared.

Humanity could be done for if Nasa or another space agency detects a space rock hurtling towards us as we have failed to prepare for such a disaster.



While the chances of an asteroid impact are small, experts believe that one could come crashing towards us at any point.

The last catastrophic asteroid event was 65 million years ago, resulting in the extinction of the last dominant species of the planet, the dinosaurs, and some experts say we will be able to do about as much as they did to prevent it – nothing.

Speaking at the annual meeting of American Geophysical Union, Dr Joseph Nuth, a researcher with Nasa’s Goddard Space Flight Center, of a potential asteroid collision: “The biggest problem, basically, is there’s not a hell of a lot we can do about it at the moment.

“But on the other hand they are the extinction-level events, things like dinosaur killers, they’re 50 to 60 million years apart, essentially. You could say, of course, we’re due, but it’s a random course at that point.”

Nasa has made great strides in discovering near-Earth objects that are over one kilometre in size, with 90 per cent now accounted for.

However, that means that there are still 10 per cent of dangerous asteroids that have not been spotted and which could come as a surprise.

But even if scientists did spot them early enough, they would not have sufficient time to prepare to launch a rocket that could knock it of its collision path with Earth.

Dr Nuth highlights Mars’s 2014

Experts had only discovered the asteroid 22 months before it whizzed past Mars, and had that been Earth, there is not much that could have been done to stop it due to the small timeframe.

Dr Nuth said: “If you look at the schedule for high-reliability spacecraft and launching them, it takes five years to launch a spacecraft. We had 22 months of total warning.”
