NASA plans to attempt to redirect a small asteroid by throwing a multimillion dollar spacecraft at it in October of 2022. They will then determine if this is a viable asteroid redirect method.

Truly an exciting time for NASA. It is good to know that they are pushing the boundaries of throwing rocks at things.

About 90-95% of the energy spent in space ventures is spent just trying to get out of the atmosphere.

Sounds more like they're throwing things at rocks. Still probably good to test the concept outside of science fiction, should we manage to detect an earthbound one before it's too late to prevent.

Conversely, I wonder how long it will take for someone to try and weaponize that technique with precision meteor strikes.

Long as their using something that is near the end of it's shelf life, I'm find with them using something that expensive.

Those satellites have to deal with those small asteroids, lost space tools on top of changes in the extremely thin atmosphere they have to travel through because of what the Sun throws at the Earth (makes them use of precious fuel). Most old satellites ether burn up or are told to eject into space, so using one try to move an asteroid is a good use of money.

I rather see that money go to not putting all of our eggs in one basket that way if the earth does get hit at least some part of humanity will survive. This is why I would rather see money the us government spends on the stupid f35 program to putting humans on mars. we could have done it awhile ago had we scrubbed some of our stupid military spending when it doesn't matter in the end if we get hit by a asteroid

We haven't because 'we need to fix the problems here on Earth first!', not because of military spending or anything like that. It's political will and popular support. Even at that, it would probably be best for (numerous) private organizations to go and do it instead.

Getting hit by an asteroid likewise doesn't matter if we're killed by barbarians on Earth.

Sadly I don't see all of our problems getting fixed I don't see that happening which is why we are doomed to become extinct. Even if aliens landed on earth this week once they left we would go back to fighting each other and nothing would changed. Dead is dead at least if we have some official off world colonies some part of humanity would survive even if we nuke each other or get hit by a asteroid. We should be focusing on space exploration and advanced technology and resource development and not stupid military programs.

I see it now, the space station hits the asteroid and it is a big success knocking the asteroid into a different path. But, that causes it to hit an asteroid it would not have hit and redirect it's path. A massive space pool ball reaction occurs culminating in the redirection of a massive asteroid into the path of the earth and wiping out all life.
