The fact that the Earth is able to sustain life is nothing short of a miracle (or God’s doing, depending on who you are). Even with our increasingly advanced space exploration technology, no other planet that we have been able to study thus far has just the right conditions to make life possible.

That’s why it’s so important that we take care of our planet and defend it. The furthest that humans have been able to travel is the moon, which isn’t far, and there’s no feasible way of us inhabiting another planet should the Earth be destroyed.

Whilst there’s a number of ways that human life could cease to exist on our pale blue dot, one of the more likely scenarios which could lead to the end of humankind is a collision with an asteroid. After all, it was an asteroid that wiped out the dinosaurs.

But unlike the dinosaurs, we have got technology which allows us to not only detect potential threats to our planet, but predict when they will reek havoc, and NASA has a few plans of action should we face a collision with a giant intergalactic rock.

NASA might be our planet’s top space exploration society, but their plans aren’t as full proof as you’d expect them to be. They’re bizarre, and, trust me, that’s putting it lightly. If you didn’t know better, you’d assume they were plot lines from sci-fi movies!

1. A gravity tractor

If you’re in any way familiar with farming, then you’ll know that your average farm would pretty much cease to function without a good old tractor. They help farmers move things around, plough their fields, and plant their crops. But they could help us out in space too…

It turns out that NASA want to create a similar device to help keep our planet safe. Although we won’t be planting corn in space, a gravity tractor would help defend the Earth by pulling any sizeable asteroids away from our planet.

Gravity tractors would be entirely reliant on the early detection of asteroids, and unfortunately, that’s something we’ve still not got down to a tee. Just this year, NASA failed to noice a passenger aircraft-sized asteroid come extremely close to Earth.
