@The Owl Lady It's physics, the energy can be calculated by the formula e=0.5×m×v² or in long form energy in Joules = 0.5 × mass in kg × velocity in m/s squared ( roughly 8000m/s if atmospheric effects are ignored) A kg of TNT has an explosive energy of 4MJ (4,000,000J) while a kg in orbit has 32MJ. So 1 ton of rod is roughly equivalent to 8 tons of TNT. Should be enough to take out an HQ but not a city. It takes the more energy to get it to Orbit and moving the orbit for targeting also takes a lot of energy some final corrections can be done.

You forget Jerry Pournelle was first and foremost a scientist and researcher, only writing and reporting later on in his career as a side line. Generally regarded as the smartest person in almost any room, and did a lot of research that was used by the military. Also has his own section in the Smithsonian Museum, and was one of the first people to use desktop publishing, in place of a typewriter, because it made his output so much higher, and revising so much easier. He was always a pleasure to listen to, and his collaborators really miss him.

@patrickscalia5088

Жыл бұрын

I wasn't a fan of the man's politics either. I still don't understand why really smart people who write popular science fiction tend to lean so heavily towards fascism. Having said that, Pournelle directly explored the concept of living in a society in which people explicitly trade away all privacy and many personal freedom rights to live in a closed, gated society with a crime rate somewhere around zero. That novel is _Oath of Fealty_ and is one of many he co-wrote with Larry Niven (who is also a renowned, famous sci fi writer.) I do have to say that the novel doesn't take the easy way out by choosing a side and there's plenty of ambiguity such that a thinking reader's opinion could go either way. It's always a good thing when a novel lets the readers do the thinking for themselves. He and Niven also wrote the first really-good apocalyptic novel about a massive comet impact on earth, and how people cope with the aftermath. Fears of a bolide strike killing everything on Earth seems to be more of a recent thing, becoming a popular meme in fiction and nonfiction only in the past thirty years or so. But their novel, _Lucifer's Hammer_ was published way back in I think 1976 and is a highly entertaining and thought provoking read. Niven and Pournelle also wrote what is one of the five or so best sci fi novels I've ever read (and I've read hundreds.) It's an alien first-contact novel about our encounter with the first intelligent alien species in human history and is utterly brilliant. Not to spoil anything but it has an intricate plot about our naive encounter with a species that is extremely dangerous, if only the characters in the novel will catch on to the grave threat they present. That novel is _The Mote in God's Eye_ and I can't recommend it strongly enough. If you're both a thinker and a reader, the novel will blow you away. Though as a genuine scientist Pournelle might be expected to lean heavily into the hard aspect of hard sci fi, his and Niven's novels also do a fantastic job with character development and even dialogue. Not exactly Hemingway or McCarthy-level brilliance in characters and how they communicate with each other, but still orders of magnitude better than most sci fi which tends to have rote or cliched characters and dialogue. Honestly, most sci fi is all about the aliens and the spaceships and the high-tech stuff, not so much about the human characters which are often so thin that they're stereotypes and mere place-holders for a space where a real character should go. Pournelle and Niven greatly transcend genre in that vital aspect.

In his book "A Step Farther Out", Pournelle discussed the Rods from God concept. His take on it wasn't that it was too expensive to implement, but that it wasn't expensive enough. Lots of money, therefore lots of profits to be made building carrier fleets, and his calculations were that just putting a few of these in orbit would cost less than one carrier fleet, and be far more effective.

@gaemr_o5147

So he thinks that if the rods were more expensive there would be more incentive for all the military contractors to invest in them. Was that the only reason he thought these aren’t being used?

There was a novel back in the 80’s called “David’s Sling” that used a much cheaper concept they nicknamed “flying crowbars”: metal rods with a simple guidance system. Small ones were used to take out tanks. Large ones to destroy missile silos. The story also had a number of “cheap” automated weapons used to overwhelm the enemy with shear numbers. Basically thinking outside the box. The concept of drone swarms is similar to what the author proposed.

Interesting point of fact: Jerry Pournelle was co-author (with Larry Niven) of Footfall, a novel about an alien invasion. A "rods from god" type weapon featured prominently in the early battles, used by aliens against the humans.

If I remember correctly, in Heinlein's "The Moon Is a Harsh Mistress," citizens of the Lunar colony launched giant rocks at the Earth in lieu of their usual shipments of moon-grown grain as a form of protest and rebellion. It was quite effective. Thanks for another great video!

I've always had a fascination with the idea of kinetic bombardment as a way of waging war... that would be the craziest way to wipe a spot from existence without irradiation everything.

Forget rail guns, the standard anti-tank round fired by most tanks is a kinetic energy projectile. They're depleted uranium or tungsten (density counts) darts with a sleeve around them to fill the remaining diameter of the barrel. The genius of the rods from god, whether orbital or just dropped from a great height, is that gravity does all the work. It's a refined version of the penny dropped from the Empire State Building. but with enough mass and a terminal velocity high enough to actually wreck things.

A variant was intended to be launched as a bundle in the general direction of an armored advance, with the guidance systems finding tanks to guide themselves to once they started their long fall. Given the widespread use of drones in recent years, especially rigging simple drones to drop grenades, I'd be surprised if the high-altitude platform version doesn't come up again.

those rocks have to be BIG. If they are small, they shatter / explode in Earth's atmosphere. And if they are big, they will be detected in no time, even by capable amateurs. Well manufactured rods can survive re-entry way better and ca be hidden in any of the many classified satellites. once launched from orbit, they hit fast, leaving very limited time for detection. And even if they are detected, countermeasures are not too easy against those heavy, pointy, crazy-fast metal sticks. If they exist, they are way more efficient than natural space rocks.

Your presentations are good for morale during a slow day at work. Thank you.

Thank you for the nod to Babyon 5, that's the first thing that came to mind when I saw this video announced. J'Kar referred to it while screaming at Molari as "when you bombed our cities with asteroids". I'd also like to point out that if you're going to try to reduce the cost of orbital deployment by saving weight and using something other than tungsten, you're forgetting that the mass of the rods represents their destructive yield. Lighter rods are easier to get to orbit, but will do far less damage on impact. I don't really see getting these to orbit as a problem, so long as you're only trying to haul up one at a time. Reloading it would just occupy Space-X for a month or two. The cost of getting things to orbit is falling through the floor right now, and is only picking up momentum. Deployment and precision could also be a problem. I'd wager if you asked 100 random people how to get a rod in orbit to hit the earth most of them would say something like "well duh, just drop it over the target". Anyone with even a cursory understanding of orbital mechanics will get a good laugh out of that of course, because you have to slow the rod's orbital velocity or it will just stay in orbit. If you want it to de-orbit rapidly, that's a lot of force required. And if it's all being done at or near the platform, then you have the problem of basically a "butterfly effect" where you need insane precision at the starting point to hit a target, since minuscule errors in your orbital burn are wildly magnified by the time you get to the ground. So the rods would absolutely require some sort of guidance. Fins would be fine, but they would have to deal with the intense heat being conducted through the rod. I'd call the precision problem "trivial" in comparison to the de-orbit maneuver though. But the two problems are linked.

Carl Sagan, writing 30 years ago in Pale Blue Dot implored humanity not to develop kinetic impactor weapons. He believed it only a matter of time before somebody decided to weaponise asteroids as their ease of use and availability would be totally irresistible. And it is unsettlingly easy to do: 1: Fly out (robot or human) to one of the billions of near Earth asteroids that best suits your needs (or you at least have the fuel to utilise). 2: Strap a rocket motor or ion drive to it. 3: Do some maths. 4: Wipe whatever city, nation or continent off the map that you don't like. The worst part of the strikes is their stealth. Even if someone gets super lucky and detects the asteroid before impact, it can't be stopped and it would be impossible to know if the strike was a natural impact event or if it was the work of human beings. So long as the perpetrators keep quiet, they will never be accused. Anyone with access to space already has the tech knowhow to make it happen. Jeff Bezos or Elon Musk would be just as capable of it as NASA or CNSA. It's going to be a continual fear for all of us going forward that some nutjob will decide it's time to dinosaur us. At least it will be until we develop some serious star trek s**t to defend against it.

the kinetic projectiles are only expensive if you need to get them into space from earth, refine the materials in space from asteroids or the moon, or even space junk, and you solve that issue, of course the cost of a space refinery is probably at least as expensive initially but it does serve multiple purposes.

@pault151

It takes more energy to lift the projectiles to orbit than what they can deliver on impact. This is only considered because once the projectile is in orbit then you can target things conveniently. The energy needed to redirect an asteroid's orbit is tremendous. Not to mention that we don't have space refineries. Just to get lightweight analysis packages to comets/asteroids takes years with orbits boosted by planetary fly-by paths. Even with the hugely reduced cost of lifting to orbit that re-usable rockets give us, it's still prohibitive to lift heavy equipment out of Earth's gravity well. This will probably only become feasible if industry on the Moon is developed to the point that the hardware and rocket fuel can be built/made there out of local materials refined on the Moon, and if the energy requirements can be satisfied by solar power harvested there including rail guns to boost things to orbit and to manufacture fuel to provide later maneuvering.

Those supplies are used to create Platform 2, which makes even more robotics and drones, more platforms, along with refining materials for other purposes on Earth and abroad. Once you’re in orbit, energy is never an issue since there is always far more solar energy than we could ever possibly capture. Water refined from the Moon is fuel for navigation and return trips, solar sails can be made for outbound trips to save even more. Once the “ball gets rolling”, the potential is staggering.

Although its thermal properties do help, there's an even bigger reason why the designers for Project Thor chose to make the rods out of solid tungsten. It's one of the densest materials you can use; only second to osmium, which is too brittle and too expensive for the job.

It also experiences less atmospheric braking. Being a tungsten rod it has a very low surface area and a huge amount of mass so it "pierces" the atmosphere and doesn't slow down much. Usually you want the opposite. Large surface area for the mass so you have a capsule or spaceplane shape. In this case you want to maintain speed so a high density low surface area on the windward side, so a tungsten rod is the perfect candidate.

The launch platform does that. Just like the third stage of an ICBM. It puts the entire stage on an intersect with the target and releases the warhead or rod in this case then maneuvers again before releasing the next. Each maneuver for the rods would be 50-100 m/s so not a great amount. The rods themselves are completely unpowered, they might have a spin up motor not sure. ICBM warheads have some solid motor jets at the back to spin them up just prior to reentry but that's more important with the irregular density of a nuke. A tungsten rod is probably fine even without spin stabilisation.

It seems that the main reason for using an orbital platform is the surprise that can be attained....except it has been shown that you can't just "drop" something from orbit. It has to slow down to de-orbit which would require a de-orbiting burn of some kind which can be detected. You also might have to wait as much as 90 minutes for the platform to be in the right position before a launch. So not much in the way of a surprise attack is gained by the cost of launching and maintaining the platform.

In that book published in the 1960s, a lunar colony established as a penal institution declared independence from Earthbound governments and used large rocks launched with an electromagnetically-powered catapult off the Moon to drop onto a couple of cities to discourage reprisal from Earth governments. The basic idea is that a big enough rock moving at speeds only attainable outside an atmosphere can shed significant mass during reentry and STILL do enormous damage to a ground target.

I think you're right that a single tungsten pole wouldn't be a WMD, but if you have a satellite in orbit with a dozen of them ready to launch, the weapon system as a whole is inching close to the definition. Additionally there's a provision of the space treaty that reads "States shall be liable for damage caused by their space objects.". Tungsten telephone poles would certainly fall under that category, so theoretically any damage caused would have to be repaid.
