Our only hope

As I've said many times right here on this here blog, a large asteroid strike on Earth is inevitable, and when/if it hits, most life on Earth, including all human life, is done. It will be something like a 90-96% extinction rate of ALL life on the planet, including bugs and bacteria and slimy stuff swimming in the seas. Consider this danger deeply, for it's very real. Here's but a taste:
And these are just the ones very close, and none of them are very big, and we're missing many, many smaller ones - the 150 meter ones mentioned below, for example. Large enough to cause widespread chaos and death on Earth (though not an extinction event). Asteroids vary greatly in size:
Vesta is bigger than many moons of Jupiter and Saturn, but not the biggest asteroid (that's Ceres, where the Dawn spacecraft is heading as I type). However, asteroids the size of Steins and even smaller are our real threat. Look how tiny! But big enough to kill us all. All it would take is 5-10 mile wide asteroid to do us all in.

And what could we do about it today? Very little if on short notice. If with 20-30 years to prepare, we could probably save ourselves, starting from scratch. But why start from scratch THEN, when we all know the answer TODAY?!
Figuratively, of course. An armada of Asteroids fighters flying around space blasting rock is not very likely.
Sad, I know. Believe me! I'm the best Asteroids Ace you've ever seen. Go ahead and try your skills here.

But no, it won't be people in triangular spaceships that save us from the asteroids, but rather small robotic spacecraft that can attach to and then redirect these Earth impacting asteroids. Imagine 50 small bots flying to then landing on an asteroid on a direct impact course, each using its rocket to steer the asteroid in a different direction. It don't take much in space.

For your regular asteroids. If a Vesta like object were coming at us, better to move off planet. Here's a closeup from Dawn:
"The Snowman".

Once again, people of Earth! Rather than a'fuedin' and a'fightin' with each other, we should instead be building a space infrastructure that 1. Enriches all life on Earth, 2. Protects all life on Earth, and 3. Spreads life from Earth.

We're all Pro-Life, right? Let's get it together, humanity! As we're the only ones here who know better. We cannot count on the other monkeys.
