Astroid defense or earths defense system sattlite

Astroid defense or earths defense system sattlite / rail gun sends a coil like ship into astroid.

( it wraps against it ) With diamond drills has rockets on back of coil ship.

Pushes astroid away .

The satlites powered by ion engine

This was my idea that could help nasa dart program and also the military. *

You may have to forgive the hand writing and look at the image yourself.

I think theirs a version of this up there too because of Ronald Reagan from a diffrent design ... ref

So you think Reagan's Star Wars defense system that was for knocking out ICBM's in space, was actually developed and deployed?

If we have that tech in space it needs to be used to zap all the crap left floating in orbit

3 threads in 2 hours, that is more a mystery to me.. how do you do it, how why rush, your two other threads below this one might not get as much attention because you keep making new ones. And where do you get your information from ?

The writing on that paper might as well be in Sumerian cause I can’t read anything on those papers. I’m far from a genius but I find it very hard to believe that a asteroid traveling 70,000 mph can be accurately aimed at by a satellite and successfully drilled. I mean even if somehow you could get a satellite/ship to line up to the point where it would need to drill would be a feat in itself. As for diamond drills , I break diamond bits all the time tapping cast iron and ductile iron water mains. I would hope that there is a laser that could be used instead of a drill. Like I said though, I’m no genius. If this can be done please correct me.

If 16 Psyche is shooting at Earth doing 70,000 mph kiss your ass goodbye and rest easy knowing the world is about to end by a all metal asteroid worth $10,000,000,000,000,000,000. Yes 10000 quadrillion dollars !

All that has to happen is make contact and budge it.
With the distances in space , a mere fraction is enough to change the trajectory tangent a bunch before it gets near Earth .

I would like to cash my share in, in advance if that’s possible Water Boy

You mean satellites, not quite sure what "satlites" are.

Good luck with your design all the same.

Thing with the star wars technologies is that the technology and material science to support such just was not quite their in the 80s, even now we would be hard pushed.

Ummm…you are aware that there have been a number of asteroid and comet rendezvous by spacecraft…right…?

Most recently with the Japanese Hyabusa 2 probe which brought back samples of the asteroid Ryugu…

So it’s not a question of…can it be done…it’s more a question of budgetary constraints…and mission specifics…

I’ve long hypothesized that it will be corporations…not governments…that will mine the asteroids for resources…

Also see…China plans…

It’s interesting that they chose the asteroid Bennu…because I wrote a fictional article in 2012 detailing using tugs and other methods to deflect the orbit of Bennu…and any other errant celestial bodies…

Ummm…attaching rockets to an asteroid in an attempt to deflect it’s orbit is the least effective or economical method…

Large Mylar reflector sails would probably be the least expensive method…focused sunlight lazed onto the right areas would cause off gassing…of course the reflectors would have to be tethered to the asteroid…and perhaps also use the solar wind to tack the asteroid over long periods of time…

What you want to avoid is breaking up the asteroid…so nuking…or slamming tungsten kinetic vehicles into them is probably the least desirable method to use…

Of course using nukes on a asteroid would make sense if it's far enough away. It would also depend on it's size too. Something 50 miles across or larger that is far enough away could possibly be pushed by little Davy Crockett sizes nukes. Or intentionally pulverize it to the point it's just gravel. Put a string of nukes in it's way so the cone of debris goes around the Earth as it passes the spot where they were to collide. Or a Tsar Bomba that could vaporize a circle around 50 to 100 miles in diameter.

In space they don't care about how large the bomb is. It's the delivery system that matters.

Naah, you're not listening to what YouSir is saying. Trying to blow up the asteroid could turn a single threat into innumerable threats. That's a no go. As for Tsar Bomba, you read more into that incident that there. IF, it vaporises a circle 50 to 100 miles how come they've got fragments of the casing on show in the Russian Atomic Weapons museum. It didn't vaporise them did it?

Every situation would be different. Comets could be vaporized. Asteroids would depend if they are balls of loose fragments or a solid chunk of Iron. And the distance is important too. A rock 10 to 20 years away could be blasted to pieces simply because it's orbit would be so deflected the resulting shotgun blast would miss the Earth. And if by chance the Earth passes through the blast zone decades or centuries later the zone would be so large that 99% of it would miss. And most of the chunks so small they would just burn up in the atmosphere.

Your nuke options would vary depending on distance, time, composition of the comet or asteroid, and the level of preparedness you were at when the threat was detected. Small ones could be vaporized. Large ones so deflected their orbit never crosses that of Earth again.

Oh, don't forget that technology is advancing all the time. In a few hundred years who really knows how fast we'll be able to go in space. A interplanetary spaceship may be able to go from the Earth to Mars in a week or even a day. Who knows but by then they just might have a ship they will poke the nose into the rock and just push the rock off course. Or just put a few rocket motors on the rock and push it into a stable earth orbit and then mine it for whatever its carrying.

To a Star Trek level of civilization a large Earth bound asteroid isn't a problem it's a opportunity.

That's not the way to use nukes for an asteroid. You'd detonate it in space one radius away, and in a precise location. You'd probably need to get it in orbit around the asteroid first with precision thrusters and confirm its location.

In space, there is no physical blast as there is no fluid, all the effect is radiation, in particular an immediate pulse of x-rays. If it's an iron-nickel asteroid (the most dangerous kind) that has a strong absorption with the x-rays and will immediately heat up and vaporize a thin layer, which when outgasses will give a force in the other direction back on the asteroid. Since you illuminated only half of the asteroid, there will be a net force.

This is how the pros deal with it: www.llnl.gov...

As has been discussed you don't want to break up the asteroid, just push it.

Even with this, you'd probably need to send a significant number of vaporizers if the asteroid is big enough to matter.

101955 Bennu is 525m in diameter, i.e. 0.52 km, or about 1/3rd of a mile. It is not nickel-iron, i.e. it's the less massive type. It was calculated that one megaton weapon in x-rays would be enough to deflect it off course. The 10 km asteroid that obliterated the dinosaurs would thus take (10/0.5) ^3 = 8000 megatons to deflect, assuming they all work right. With an enormous industrial effort it might now barely be possible to do that mission.

50 km is doom.

More safe and clean is to land an ion engine on the asteroid sufficiently many years ahead and have it thrust for years to deflect the course or numerous controlled kinetic impactors for smaller asteroids.
