>NASA announces irl impulse thrustersQuite literally the biggest actual happeninghttps://www.youtube.com/watch?v=6XsqSA9tNfY
>>534268423Does it utilize mercury plasma
>>534268514Its quite literally what the near future propulsion ksp mods useForget mars, shit has interstellar applications
Now we can go around the moon in one less day! Who the fuck cares?
cool, now send a satellite to Europa now so that we can create an underwater colony there.Yes there is confirmed 100% water underneath Europa's surface.
>>534268423Oh wow, this truly deserves more taxes, tax me harder government, we need more space bullshit to waste it on
>>534268423Is this the trollface magnet drive?
>>534268423We should make another pioneer craft but with a nuclear power supply that can reach insane speeds
>>534268914Vgh, Evropa
>>534268914underneath 1,000 km of ice hard as granite. Deepest hole ever dug on Earth 12,000 meter.
>>534269041Power one up to half the speed of light and slam that sumbitch into india
>>534269370>underneath 1,000 km of ice hard as granitefugg... you're kidding right :(?
>>534268806The main thing i think is more continuous thrust, which i mean...... it could probably cut a round trip around the moon down to just 2-3 days. A trip to mars would probably be like 1-2 months instead of 6 months. etc.We could probably catch up and exceed the Voyager probes in 1-2 years. Some smarter than me will have to figure out how much thrust a 120kw actually works out to on a typical satellite/rocket.
>>534269409The ocean is also over a 100 km deep. Water might be in a different state of matter at that depth.
>>534269370How many nukes do you think would be able to crack open the ice?
>>534269409Theres parts where the ocean jizzes out
>>534269523yes the vents... probably the first to be explored and probed if we get to the surface.
>>534269487>Water might be in a different state of matter at that depthelaborate? like... bro im retarded, you dont mean D2O (heavy water?) or something like that right?
>>534268423What is with NASA and their never ending quest to pretend making useless shit?
>>534269380Ponder the smell as the vaporized poojeets form clouds and begin to rain down on the rest of the world.
>>534268423it's still gonna be "generation ships" isn't it.
>>534269604>elaborate?we don't exactly have any ultrahydrogenic supermatter to make comparisons with yet
>>534269604under extreme pressures and temperatures water actually takes different crystalline forms some of which are theorized to potentially be stable at normal atmospheric pressure which actually could be disastrous if it was ever produced on earth, but it could possibly be used in untold different technologies in space as superconductors, various other materials sciences, etc.
>>534269604No, not just deuterium. It might be compressed into some kind of super ice, hard as diamond and possibly superconducting.
Just imagine where these will be in 10 years.....
>>534269761kek>>534269794I see, I did not know this. interesting. thanks.>>534269810very interesting. thank you.
>>534269487Iirc it has a name but am retard
>>534269433Retard here, if space doesn't have gravity doesn't that mean objects maintain their inertia? Is there a top speed something can move in space where it's free from drag?
Two-way sex-conditioned spirals are the consummate individuals of all Creation. 'They condition all bodies with the condition of their bodies. They unfold all idea from stillness of Mind-knowing into moving form of Mind-imagining and refold it into the stillness of Mind-knowing. They are the electric workers which fulfill desire of Mind by interweaving threads of light into patterned forms and recording those patterned forms in the still Light which centers every spiral pair, as the axis of a cone centers the cone.>the secret of light, walter russel
>>534269433>We could probably catch up and exceed the Voyager probes in 1-2 years. Some smarter than me will have to figure out how much thrust a 120kw actually works out to on a typical satellite/rocket.wait... if we get enough solar + nuclear power or whatever the fuck. what is stopping us from just thrusting to infinity?>>534269964this is what im wondering but im retarded and not a spacefag
>>534269964>Is there a top speed something can move in space where it's free from drag?299,792,458 meters per second
>>534268423Whenever I look into this stuff I inevitably find that it's already been around for decades.
>>534268423What do these throw out the back? I reckon electricity alone won't make it move.
>>534268914There's aliens there then. Fugg
>>534270046>>534269964speed of light is the limit.anything with mass can travel faster than light.
>>534270129https://store.steampowered.com/app/602960/Barotrauma/
>>534270156can't*
>>53427010915 years. It's planned that way. The guy who patented the compression algorithm for DirectX 3D texture mapping told me this.
>>534270115Same as an ion drive, throw plasma really hard with electro magnets, except instead of being limited to solar panels its a nuclear reactor
>>534270085>>534270156>>534270217reminds me of gamma ray bursts for some reason, thinking about the speed of things. thank you for the info though, sounds obvious in hindsight kek.https://en.wikipedia.org/wiki/Gamma-ray_burst
>>534269964its all in this book
>>534268423Screw you MIT guys I told ya we were gonna invent interstellar travel first! California Uber Alles!
>>534268514Shaddup, Spock
>>534270273Nuclear reactors boil water, they don't make electricity
>>534270273About how much lighter will that plasma fodder be compared to regular fuel tanks?
The earth is flatSun is electric and localNassa prays to the 666
>>534268423>>NASAfake and gay
>>534270525anon, they don't understand steam turbines here
>>534268914With this engine the pilots would only experience 30-45 minutes depending on reverse thrust time, but for us here on Earth the travel time would still be a quick 1.5-2 hours again depending on the reverse thrust time. That being said there's nothing powerful enough on Earth including nuclear that can power it. We would need a fusion reactor.
>>534268423Only useful if they can get you into space from Earth
>>534268423Its not propellantless thrust.
>>534270324what book ? i find this fascinating
>>534269433>It is physically impossible to accelerate a 200-ton mass to 1/4 the speed of light using only 120 kW of power. >The energy required to accelerate 200 tons (200,000 kg) to 0.25 times the speed of light (c) is approximately 5.63 x10^{18} Joules.>At a constant power output of 140 kW ($140,000 Joules/second), it would take approximately 1.4 million years to reach that speed in a vacuum.It would definitely have maneuvering potential, but for actual space exploration, pretty much useless. We aren't getting off this planet, unless there's an evolutionary leap in mechanical physics. Better hurry.
>>534270384jello biafra is the biggest sell out in the history of rock and roll
>>534270525>Nuclear reactors boil water, they don't make electricityexplain the the nuclear thingy on the voyagers then
>>534268423ok nigger see you in 10 years
>>534269409There are cryovolcanoes that go ask the way down, and you can slowly melt the ice to go down. I'm curious especially if what the temp is right below the ice
>>534268423breaking news...
>>534268423>scientists who made that discovery vanishing in 3…2…1… The reptoids would never allow that.
>>534268914Don't make me tap the sign
>>534270875Then you add more engines
>>534270927They boil the water they took with them. Might be a good way to melt a hole in Europa though, I think it worked in Greenland
>>534269370>underneath 1,000 km of iceBased on recent data from NASA’s Juno mission (2022–2026), the ice shell on Jupiter's moon Europa is estimated to be roughly 18 miles (29 kilometers) thick on average.
>>534270650Apparently
>>534269487Deepest I've heard is 13km.That's~ 20000psi.100km is ~150000psi.You don't have to convince me, I'm pretty convinced in how ignorant human society is. I don't even know if we're capable of creating that pressure yet, but the spinning ball called earth and all its voids of molten and solid metal is, and 1000 times more. Life exists on the surface. I'm not saying living things don't exist in that pressure, but nothing that breaths or has a heart beat does.If they do, we're not even a distant fart on their spectrum for reality. Good speed. Don't forget your boosters, retards.
>>534268423>doesn't even drop the hookLemme know when it's something other than Hall effect.
there will be no colonies until people figure out some kind of hibernation. or have generation ships where people live and die and breed travelling for centuries.
>>5342712181 million engines still takes a year because of efficiency issues. For a 20 year trip one way to alpha centuri. And we don't have that kind of time. Evolutionary. Letdown.
>>534268423How is this MPD thruster different from the hall effect thrusters that have been around for decades?
>>534268423It's just better ion thrusters. That's it.
>>534271482>have generation ships where people live and die and breed travelling for centuries.this sounds funny and morbid at the same time. literally no choice or autonomy but to just heckin go to alpha centauri FOR TEH LULZ
>>534271115Will Sharper Image have these thrusters in stock?
PSI will be far lower, it's a moon not a planet.
>>534268423These things produce grams of thrust at most, literally useless for everything except slowly altering orbital trajectories and the like.
>>534269618Getting normies to pressure politicians to give NASA more money for dem programs.
>>534268423Now i can finally go to uranus, onboard the USS Niggers Tongue My Anus
>>534269487Well it's not as if you find units of depth on a phase diagram. Europa's gravity is only 13% as high as Earth so the pressure will be comparable to the lowest point's on Earth oceans.I'm still not entirely convinced there's life there because it's geology is quite different than Earth's (obviously) and cryovolcanism=/= earth volcanism. Lower temperature and more importantly different chemical composition.
>>534271724except we've been using them for all our interplanetary probes for decades. the difference for this ion drive is that its built for a nuclear fission reactor, so much higher energy than previous ion drives that relied on nuclear batteries or solar. and they're planning to scale it up further for more powerful reactors in the future. it basically cuts the costs per pound to mars in half or shortens travel time. previous ion drives were up to 7kw usually less, this one is 120kw.
>>534271482No goy you can't go faster than the speed of light. Jewish physics says you can't.
>>534268423this surely got ACE'D
>>534271558It appears they turned up the voltage to improve mass efficiency in return for reduced power efficiency.
Lol the AI grift is over so now NASA/USGOV wants to go back to 'le heckin' space!' as an excuse for deficit spending
we could have done this decades ago but for political reasons allegedly putting nuclear fission reactors in space was a big no-no, now suddenly it's not a problem at all for no particular reason.
>>534269370>1000km no way, not possible i don't care what nasa trannies say 1000km layer of ice with liquid water underneath is not something that would ever exist unless maybe it was a gigahuge waterball planet the size of a gas giant
>>534272478https://en.wikipedia.org/wiki/Aircraft_Reactor_ExperimentThe US immediately got on to testing nuclear propulsion for aircraft right after WW2 ended.In fact, they even started considering building ALL BIG SHIPS with nuclear reactors.Nuclear was all the hype in the 50's and 60's.Around that time, the original Godzilla movie was released, the first notable anti-nuclear sentiment in popular culture.
>>534271482>generation ships>sol colonies are we talking about colonies for fruit flies or something?
>>534272478fission reactors are ancient technology at this point and i don't think anyone cares/cared.nuclear rockets on the other hand are super cool and super dangerousimagine something powered by a constant nuclear explosions
>>534273239>nuclear rockets areThe orion drive is fundamentally retarded. At no point in design did anyone stop to wonder whether they should go back to being a fucking janitor.
>>534270525Nuclear reactors generate heat, that heat can be turned directly into electricity with a thermoelectric generator
>>534273239nasa had a nuclear thermal propulsion drive fully built and operational in the 60s called nerva. it used nuclear heat to burn hydrogen without need for carrying oxygen tanks. very practical at the time and totally would have worked in space but cancelled for political reasons.>>534273302i don't think he was talking about nuclear pulse propulsion but maybe he was and yes dropping nuclear bombs to blow up behind a pusher plate like project orion was clearly never going to happen. newer designs based on project daedalus using inertial fusion confinement are more practical and ignite pellets of deuterium and tritium behind the ship with a laser and ride that explosion. this is actually the only practical interstellar engine design (aside from laser sails, which would need to be very lightweigh craft with big sails pushed by lasers) that looks feasible in the near future and could travel 6 lightyears in 50 years. or maybe he was talking about a direct fusion drive (these are how star treks impulse drives actually work), where the fuel is deuterium and helium 3 to create a fusion reaction that is used directly for thrust. should be easier to build then a fusion reactor since you're not trying to contain the reaction. pulsar fusion in the uk is working on that for pic related, a nuclear tug that can push payloads like a starship to mars in 45 days instead of 7 months or pluto in 4 years instead of 10.
>>534273566using them to boil water is more efficient thoughbeit
>>534274097He said "explosions." He was definitely talking about the halfwit nuclear surplus retardation.Nerva and nuclear saltwater are the only direct nuclear drives worthy of discussion. Turns out critical mass matters.
>>534274097I would bet any amount of money that this is vaporware.
>>534274285yeah probably. not because it's impossible or a bad idea though but because its the uk, they kind of tend to propose some big space idea every few years to collect funds and then just kind of give up years later despite having built some early stage prototypes. like the skylon single stage to orbit spaceplane that was to use a hybrid jet/rocket engine. or the old british rocket program, or their moon landing plans where they had a cool spacesuit that looked like a medieval suit of armor. flashes of that old british ambition tempered into shutting down by the new british mindset of being sad feminine cunts.
>>534274596
>>534268423Ion drives have been on the drawing board for a while. All it is is a low-energy but constant means of thrust. You don't rocket away super fast, but you also don't need a lot of fuel, and can thus achieve high speeds over a long period of time while saving tremendous amounts of weight. You could do a trip to Mars in maybe two months.
>>534274807they've been in active use for decades not just on the drawing boards. the difference is this new one is 120kw not 2 to 7kw. made possible by a nuclear fission reactor to generate the electricity instead of the usual weaksauce nuclear battery or solar. this could have been built decades ago but wasn't for political reasons around nuclear in space that randomly are no longer a concern to anyone, making me think they never were a concern and it was just an excuse to not spend money on space stuff until competition forced them to. now that we have reusable rockets the cost of access to space is going to be low enough soon that we're dusting off old ambitions to put into space.
the 1960s ambitions for what space travel should be like in the 1970s is finally here in the 2030s!
>>534268423the fucking voyager mission had nuclear batteries in the 1970's that have kept it power until todaythis is bullshit
Oh cool, space: a bunch of nothing and some rocks.
128kw is not really that much, they would achieve speeds comparable to normal fuel thrustersstar trek plasma thrusters in the XXIV century generate around 20k MW
>>534275223.. and with new and improved biomass fuel of billion shit skin locusts to power a rocket all the way to the center of the sun
>>534274596They made a huge investment in the engine tech for the Skylon and then just abandoned the whole thing. Pretty fucking wild when governments invest enormous resources only to quit right before crossing the finish line.
>>534276397there's billions of shit skins to feed and breedstop being greedy
>>534268423That's not even new tech and every thruster is an impulse thruster you mong.
>>534276010yes, nuclear batteries, but that's not a nuclear fission reactor. huge difference in power output.
>>534268423>impulse thrusterskinky
>>534274807Ion thrusters suck ass. They are efficient with regard to reaction mass, but they eat massive amounts of electricity and the force they generate isn't even a stiff breeze. They scale like dog shit. Fine for tiny probes, but actual garbage for anything with real mass.
>>534268423What does this mean in simple words? I'm retarded
>>534269794So basically prions, but for water itself.fuckin whack
>>534268423How does this help me get healthcare and an affordable comfy life?
>>534271115There's an entire youtube channel with a dude who wears way too many rings makes actually kinda decent ionic thrusters.
>>534268634How much do the batteries weigh?What's it's torque?
>>534268423Ion thrusters have been a thing for at least 20 years nigger
>>534272664>In fact, they even started considering building ALL BIG SHIPS with nuclear reactors.We somehow figured out how to perfect it for submarines - but never cargo ships.
>Switch to impulse engines>Ensign, guide us within transporter range
>>534275044So basically Nasa is tired of getting BTFO by Musk's rockets and now are experimenting with things that the government will never give any approval for any private company to play with.
>>534269794This was the plot of a Kurt Vonnegut novel, someone creates a form of ice that works at room temp and it gets loose, "teaching" all the water on Earth to freeze that way, and the characters have a bunch of pointless conversations while they run away from the ice as it spreads to cover the entire Earth and kill everyone.
>>534277470yeah, private space does the rockets better and cheaper than nasa ever could so they need to find something new to do to justify their budget. nobodies going to want to fund another sls once starship is fully operational and getting things into space at 10% or less of the cost.
>>534268423Meh compared to nuclear thermal.
>still believes NASA >still think space is realEmbarrassing
