Should we be prepared?

Tomorrow morning the asteroid Asteroid 2012 DA14 will pass by the earth. At its nearest approach Friday (Feb. 15, Morning of February 16 NZ time), the 150-foot-wide (45 meters) asteroid 2012 DA14 will be just 17,200 miles (27,000 kilometers) from Earth (within the orbits of geosynchronous communications, weather and navigation satellites) — the closest encounter with such a large space rock that researchers have ever known about in advance.

This brief video provides some information.

NASA TV will also run a live commentary of the flyby  February 15 11 a.m. PST (2 p.m. EST) US time – 8 am NZ time.

Should we worry?

Nothing to worry about they tell us!

But here’s what worries me.

This asteroid was only discovered a short time ago (within the last year). The fact that it will pass so close indicates a reasonable chance we could actually be hit by an asteroid that size any time. One capable of destroying a major city.

There are larger asteroids out there. Some large enough to cause world-wide damage – even extinction of life.

Shouldn’t we be doing something about this possibility?

Yes, I know we are busy finding and mapping orbits of near earth objects. But what would we do if we actually found one that was on target for a direct hit? With notice of only a few month?

We should be working hard to develop the spacecraft and techniques capable of diverting such objects. And have them ready, able to do the diversion with very little notice.

I suspect we already have the technology and ideas to produce such craft.

Several years ago I was shocked at the reaction of some US space enthusiasts when the Russians announced they were putting effort into systems for diverting asteroids. They seemed to think the idea was fanciful.

Fortunately, since then the US has announced plans of their own to at least develop the ability to make manned visits to asteroids.

Surely space-faring nations should be working together to urgently develop the ability to divert near earth object? The future of our species may depend on it.
