I guess in the end, it always boil down to money, or the lack of it.

Creating such systems will not be cheap, as will as the maintenance and the labor for it.

We can simply ignore the threat, of an annual 100ton debris falling on Earth, hoping for the best, or find cheaper but efficient practical ways to deal with it.

Currently, Norad, Nasa and other space observation installations in richer or insecure nations electronically track the globe daily for rocket launches, satellites and high altitude aircrafts. Big rocks can be tracked as well, but unfortunately, it is the 10ton rocks that can level 6 cities at one go that cannot currently be tracked.

Our space rock threat is thus not big rocks, but the small and fast untrackable ones such as those which hit Siberia few days ago.

Perhaps, universities around the world can try to get their science students to come with ideas on how to deal with those small tracks. I am sure out of the many thousands of graduating students, some of them are bound to have a brilliant idea of 2 for some cheap and effective measures.

Anway, its time we look towards space for resources, as at the rate of our consumption, pretty soon resources will be far costly to mine on Earth, and planets/asteroids may be cheaper, the way expensive oil had lead to fracking being a cheaper alternative.

And the best place to look for ideas are from our young, whom are free from funding worries that researchers often have to face, as University fundings comes from both the govt/People and charitable organisations, which can be put to good use rather than to repeat experiments or studies just to get a degree or Phd. At least that would be a direction that has more relavance for mankind.


The DOD spends about 700 billion annually! Thats a hell of a lot of money. And the recent wars added another few trillion to the defecit. If even 100 billion was diverted to nasa or the air force I feel they could do some really "cool stuff".

It is simply a matter of putting things in perspective by using common sense. I get tired of repeating myself but the ptb bankers are an evil bunch. These are the people pulling strings and holding on to the purse strings. All masons too.

I believe that we should separate realities from speculations, so that we can deal with realities better than speculations which are often unsubstantiated or difficult to prove.

And the realities had literally hit home with those small 10 ton rocks in Siberia - we need to watch the skies, not only big rocks, but the small ones as well.

Most major space agencies can deal with big rocks, in terms of tracking them and even diverting them if need be through nudging them off their trajectory for asteriods or robotic crafts landing on larger rocks to detonate them far from Earth.

But most major space agencies cannot track small rocks which can cause considerable damage in population centres, with our current tech. Thus the only way is awareness and warnings for preparedness.

One way is to for every major population centres in our world to individually track the skies, from Tibet to the Samoan islands. It will not cost much. Just 2 CCTV cameras on highest points, and rotating shifts of 2 men to scan the skies 24/7, along with computers to link to major tracking centres for atmospheric changes.

1. Any disturbance upon our magnetosphere can be tracked, even small rocks as they would be travelling at high speeds, and when they hit the atmosphere, they will either burn up or cause a spike in the magnetosphere readings. It may be miniscule, but if our satellites have fine tuning instruments on board, it can show up better on record, as well as even its GPS location.


2. Once the GPS location is confirm, the CCTV cameras scanning the skies near that location will be paused to search in that direction, magnified, for visual confirmation and computerised plotting of eventual trajectory to Earth, all capably done within seconds by the computer.

Should it be plotted to hit the sea, then leave it alone. However, if its trajectory will hit cities, a general alert will be sounded to warn all residents to either get into the strongest parts of the buildings, go into bunkers, get out of cars and stay off streets, Health, Fire and Emergencies services immediately stop whatever they are doing and get ready for action anywhere.

All these must be practised, drilled or in the least published in a handbook for a residents to know what to do when meteorites hit. Citizens will have less than a minute to prepare, for the speed of the crashing meteorite will be extemely fast.

All these, to save precious lives, as our population grows and more moves into modern population centres or creating new population centres such as those in China, Brazil, Russia, etc.

I agree with with you, i did say we need a faster delivery system, and it seems a better idea to make them miss rather than try to completely annihilate them considering you run the risk of fragmenting them. Even better if we could stear them into the Sun, that way they will not hit anything else.

How are you suggesting we change there trajectory once there?

Depends how massive it is and how close it is when you get to it.

If its small enough/far enough you could gravity tractor an object by simply maintaining station close to it. The object and the spacecraft will exert pull on one another. If you use propulsion to maintain a fixed distance you will slowly pull on the object. Thats a pretty elegant solution but its dependent on a lot of things. The farther away you meet the asteroid the smaller the amount of motion you need to give it to trigger a miss.

The other solutions all require interacting with the body directly and i've heard a number of ideas, from attaching electric thrusters to excavating mass from it and throwing it off into space at high velocity.

We need a tool kit since not every option will work best for all asteroids.

Bigger bombs are some way down the list of tech we need to solve this problem. Although its historically always been easier to get money for bigger bombs than science, utility be damned.

What about using scalar interferometers on them, i think Tesla had some ideas maybe even designs regarding those type of devices. He was way ahead of his time. If they have made any progress using his famous missing diaries who knows what they contained or what they have in there arsenal now.

Nature demands that we explore space.

Since we are a part of nature we have only three true goals in life. Meaning that nature doesn't care what we do as long as we:

1. Multiply. Every successful living thing on this planet is designed to spread as far and wide as it can.

2. Eat or be eaten. This drives evolution and renews life in a way that doesn't leave dead and rotting things poisoning the environment.

3. Spread life throughout the universe. This ensures the continuation of life just as mold will spread from one fruit to the next.

If we don't master the exploration of space and start to colonize other planets, we WILL die out from one catastrophe or another. <-- Getting off this planet should be our ONLY goal now.

Indeed that is the only way to guaranty our survival as species but personally I don't have hopes for our species

Nukes just fracture them up and are way to slow to be effective.

Lazers and particle beams don't yet have the power to do much either.

Solar sails, well again way to slow, you would need many months if not years to prepare a mission.

Lets face it we need antimatter capabilities and a faster delivery system to stand any chance against these things.

You detect them early, meet them when they are still distant and nudge them ever so slightly.

We don't have to destroy anything, just make it miss.

A better detection network and a nuclear electric or nuclear thermal propelled spacecraft is what we should be working on. All doable right now if we could be bothered. Which we cant. :-(


We ALREADY HAVE the proper technology but it seems to be focused downwards rather than into space. Look into HEL(High Energy Laser) and GRASER(Gamma Ray Amplification by Stimulated Emission of Radiation) systems which has marginal information available in the public domain. Most of it is CLASSIFIED and cannot get access to.

en.wikipedia.org...

Why fool around with "nudging them around" when you can obliterate them?

We have plenty of alien technology but its either kept in the dark or used against humanity. And lets not forget the star wars program initiated by ronald reagan to destroy soviet nukes inbound towards usa back in the 80s.
