Mass balloons rather fast when you use a lower Isp engine to get closer to that 7.389 mass ratio with a given payload mass (flak bombs used instead of KKV penetrator to avoid making new modules): That face-melting terminal acceleration almost makes the absurd wet mass worth it... Er, not exactly. The e^2 result is for fixed wet mass and Isp. Total Δv is a free parameter. If instead you've fixed Δv, (5 km/s in this case), then kinetic energy is maximized by minimizing mass ratio. That means choosing a high-Isp engine, within the constraint of reasonable acceleration. In general, you can always improve the performance of a rocket by increasing exhaust velocity, provided that doing so doesn't require violating some other constraint (initial acceleration, cost, reliability, etc.). The only possible exception is that, if you have multiple types of engines on board that have separate propellant tanks, it's best to use the low-Isp engines first. They were able to stretch the payload capacity of the space shuttle a little that way, by burning the OMS engines during ascent. So If I set my wet mass to 1000kg, a mass ratio of 7.389 will give me the maximum kinetic energy regardless of what my engine Isp is (though the exact amount of kinetic energy will vary depending on engine performance). But if I set my deltaV, my ultimate kinetic energy will be a function of Isp. Is that right?

If you are building a KKV i dont see a point in using a 50 kg inert rad shield pill as the payload. Part of that weight would be better off as a carbon steel nose cone underneath the anti-thermal armor. It should help negating the whipple shield if the impact is nose on. And still Better yet would be to use most of the extra mass as fuel. Not necessarily. There's a proof floating around somewhere that the mass ratio that maximizes kinetic energy for a given wet mass is e^2. That's approximately 7.389, and it corresponds to Δv equal to twice your engine's exhaust velocity. Though starting from the specified 5 km/s Δv in this thread, more fuel is going to be the answer for most reasonable engines. KKVs kind of suck though, in my experience. The first one makes a small hole through the center of the radiators, and every subsequent missile goes through the same hole. They probably are a good answer to pointy ships that fight nose-on, though, since a KKV has a good chance of coring the ship if it hits from that aspect. Mass balloons rather fast when you use a lower Isp engine to get closer to that 7.389 mass ratio with a given payload mass (flak bombs used instead of KKV penetrator to avoid making new modules): That face-melting terminal acceleration almost makes the absurd wet mass worth it...

I suggest you read the novel On the Beach by Nevil Shute. Not a scientific treatment of the topic, but an excellent treatment of hopelessness and misery in the aftermath of global nuclear war with salted weapons.

The thing is, the intelligent designer can study the result of said billions of years of evolution, and try to improve on it. They can also use vastly accelerated evolution cycles in whatever desired conditions to improve on them (as types of machine learning and design do already), be it through simulation or with fast manufacture. It can also use processes and designs that wouldn't have happened naturally through evolution due to the too great leap in complexity. For example, while there are a tiny handful of organisms actually using metal, none ever used anything resembling ball bearings as far as we know. Same for high-performance materials, most engines, radio communication... So an intelligent designer standing both on the shoulders of giants, of the many many normal-sized people we tend to unfairly forget and of the aforementioned billions of years of evolution can create a vastly more competitive ecological system made to be hostile to humans and human machinery. As for existing life, it can use it, infect it, cohabit with it or exterminate it depending on cases. Some life may adapt well to it even - unless the designer also wanted it to destroy all life, then most (though probably not all) will be destroyed. It doesn't need to turn the entire surface into grey blob anymore than life as we know and love did to claim Earth. About whether stains will fight each-other, this will have to be planned for, and would probably be set to accelerate mutation and adaptation. It may be ultimately unstable and either waste away or become more benign down the road, but if down the road is in a smattering of millennia, it may be good enough anyway. True up to a point. Remember however that by using an ecosystem based approach you're adding complexity (indeed probably more complexity than any individual organism conceivable). The complexity vs replication time dilemma will apply to an ecosystem based approach too: We no longer need to build a swiss-army knife nanobot (an aside: nanobot or nanomachine is probably a misnomer if it's complex enough to self-replicate. I'd expect sizes closer to a bacterium, on the order of one micrometer) but instead we now have to build many different kinds of simple ones at the same time as they cannot function without each other. Think of how long it takes for a rainforest to grow, compared to an algal bloom or other short-term phenomenon involving only a few species of simple organisms. It's still more efficient than trying to do everything with one life form, but the problems that apply to the simple case don't just go away. Another advantage of an ecosystem is that they're usually much harder to destroy than a single kind of organism, which is great for long-term survival of the system as a whole (not so much for species within it, as Homo erectus can attest). It doesn't really add up to taking over the world though, especially since each environment will favour a different ecosystem (an ecology of nanites that only work well above 0 degrees C won't be taking over Siberia). In addition, an ecosystem may be vulnerable to attacks that a simple swarm is not: attacks that disable certain 'keystone' species may compromise the entire system, even if the rest of species in it are largely unaffected by that kind of assault. We also need to go back to those first couple of questions I asked: What is the nanomachine made of, and what does it use for energy? Can it get those two things in sufficient supply to do what you're describing on a timescale that makes it unstoppable? Natural Life has a monopoly on the best raw materials and energy sources (carbon for materials, sunlight and carbon for energy), and while you can use organisms as food you shouldn't expect them to roll over and take it. Taking the 'it eats all life' route also presents us with a handy (if monstrous) way of stopping the plague from spreading: Burn everything bigger than a microbe in a large circle around its current location. No energy = no spread. One final point: The level of complex interaction you're describing basically rules out the idea of the nanobot plague being an accident. We must then ask: Who is smart enough and has the resources to make such a complex nanoweapon, yet crazy enough to want to destroy Earth's ecosystem and stupid enough not to use a more expedient method like programming a horde of simpler nanobots to refine U-235 from the ocean and using it to nuke the entire planet? And if design on this level of complexity is possible, what's to stop someone else who is equally smart designing the perfect countermeasure for the nanoplague, one it simply cannot adapt to overcome? None of this rules out the nanite apocalypse, of course. Instead it makes setting up a believable one much harder, and much more interesting. The aftermath will also be very interesting: Rather than a featureless ball of grey goo we'll have a living, breathing ecology, fighting and competing with both itself and natural organisms for resources. At that point it stops looking like Cthulhu and starts looking like something that, rather than being evil, is simply different: too different for us to live with, but not devoid of its own value. Could make for an interesting setting.

Is that an escape ship for criminals? as the manufactuor of my ship, I hold no responsibility for the actions of those who purchused my ship, they need good karma and luck to make it to orbit anyway, as well as a launch with the planets rotation, on the equador, with a tailwind, no clouds, and a low pressure zone, from a mountin couldn't you delete one or two engines and use the weight savings to improve Delta-V? You'd also avoid the suicidal G-forces.

My original Escape 1 did around 1.5g on liftoff. Silly as it is, could you add my giant 'Exodus' ship to the list? I've revised the engines for higher chamber pressures (using a diamond chamber with maxed thickness) and expansion ratios at the same nozzle exit pressure. Combined with changing the crew module shell material from boron to magnesium I've managed to increase total passenger/crew capacity to 24000 with a cost of 699 Mc. I think that makes it competitive with pttg's Spartan Keel in cost/seat. I also feel I should get a bonus for making a ship that can be recycled as a space station once it reaches orbit . Sorry, but realistically it'd blew up... Structural failure/Magnesium + air + some heat? = spectacular explosion Anyways, THIS IS THE GAME, SO WHO CARES! Added. Magnesium autoignition temperature is 746K. With a sane launch profile I don't see it catching fire. However, as a precaution the interior of the crew modules is subject to a strict no smoking rule.

Updating the cost/person for EVC 40 -> 50 and EVC 100. EVC 50: 73,800 c/seat EVC 100: 62,500 c/seat The seats are free in real game anyways. Btw, I noticed that most people's rocket designs have thrust lower than 1.3 g. This is reasonable if the rocket is actually used in orbit, but those are very inefficient on Earth due to immense gravity loss. PTTG: Spartan Keel -- 1.24 gRandomletters: HVL-N -- 1.13 gArgopeilacos: Earth Escape -- 1.31 gSomeusername6: Escape Ethane -- 1.23 gMmmfriedrice: Escape TSTO -- 1.17 gRandomletters: HVL-C -- 1.13 g/ 1.24 gNerd1000: Escape 1 -- AdmiralObvious: Orbiter -- 1.21 gThe Astronavigator: EVC (all engines on) -- 1.65 g/ 1.91 g/ 1.60 g/ 1.57 g (Note that in real flights, some of these engines are spare engines, or will cut in-flight to reduce the g-load) My original Escape 1 did around 1.5g on liftoff.

Depending on the intelligence behind their creation, I don't see how organic life could ever compete with nanomachine swarms. If a particular organism is competing with the swarm then new nanomachines can be intelligently designed to counter it. I highly doubt that organic evolution can compete with this process. The problem isn't any specific organism. The fundamental problem is that if you build a self-replicating nanomachine you've created a life form. It will therefore be subject to the same rules as organic life, and no amount of intelligent design will fix that. You'll inevitably run into the complexity vs. replication speed problem, the speciation/competition problem, and all the other things that hold natural life back from doing the same 'grey goo' conversion of every available substrate into themselves that we imagine the nanobot swarm doing. An intelligent designer may be incredibly smart. But evolution has had 4 billion years to refine organic life into the ideal grey-goo micromachine that can outcompete all others. It's created life so different from the norm that it's hard to imagine: There are Archea that thrive in boiling water, microbes that gain energy by oxidizing hydrogen gas from volcanic vents, bacteria that can rebuild their entire genome after it's been shredded by enough radiation to destroy hardened electronics. If a single all-consuming organism is feasible, why does earth not have a single, dominant bacterium that's eaten everything else and become the sole species? We've sure as hell had long enough, and selection pressure massively favours the appearance of an organism like that. The answer is that there's no single maxima for fitness. Every trait comes at a cost. Every optimisation for one environment is a disadvantage, possibly a fatal one, in another different environment. Every countermeasure has a counter-countermeasure and evolution is smarter than you: Those counter-countermeasures already exist, waiting in the population at low levels, waiting for a selection pressure... In other words, an intelligent designer can optimise his/her/its grey goo to resist competition from a particular organism, but doing so will almost certainly compromise on some other desirable trait, such as replication speed or even its ability to compete with another, different organism. Evolution won't stop either: you might deploy your countermeasure against Staphylococcus nanobotophaga, only to find that the bacterium already had a plasmid or mutation that acts as a counter-countermeasure present at low levels in the population, and you just made a very strong selection pressure that favours the bacteria carrying that plasmid- they promptly replicate at a slightly slower speed than the originals, eating up your nanomachines in the process.

Seeing as I'm posting challenge ships: Here's Eros's Arrow, my attempt at the 1 kg uranium challenge. This ship is an entry for both the regular challenge and the gold level, as its reactor uses 506g of U-233 dioxide. I'll enter a fleet of 2 ships for regular, and just one ship for gold. Hopefully I haven't accidentally added any uranium somewhere else. Ship export:

necro time! Here's my entry: It can match my 12.6 km/s Delta-V record for Homecoming with 400 m/s to spare. The non-titan materials are all in the reactor, which uses 1500 grams of U-233 dioxide as fuel/control rods and around 500g of Nickel chromium iron in the thermocouple. Mass ratio is very high, around 15.5 IIRC.

That's your main concern with this design? Also, it's probably not as important as you might think: Edit: Fixed
A quite unusual rocket as i never saw rocket with nose like that. BTW did i just saw the phase " titan liner" in your design list? It was a design for the 'Titan Liner!' build challenge that I didn't end up posting.

You forgot the aerodynamic nose nerd1000 . That's your main concern with this design? Also, it's probably not as important as you might think: Edit: Fixed

You people are forgetting that this is a MASS evacuation. Stop thinking small scale and start looking at ECONOMY OF SCALE!CHALLENGE ACCEPTED Given this ship's biblical size, I gave it a rather biblical name to match.

If it's too dumb to work by itself, why even bother with self-replication? You could build your nanobots more efficiently in a centralized factory, then ship them to where they're needed.
