Rawr900 I'd say that's probably incorrect especially since this is the top comment if you are on desktop you would see it regardless until you fullscreened
I'm disappointed that you didn't use Railguns to fire your Railgun to the moon, and another Railgun to slow it down when your Railgun is about to hit the surface of the Mun so you can use the last Railgun to shoot Kerbin.
Max John here is something iv had for the past 3 days and i already love it heres a link Check this awesome launcher on playstore play.google.com/store/apps/details?id=apptech.scifilauncher
60km is enough precision to "roughly hit a major city". Considering the energy of such a space projectile, it will be more than enough to cause widespread devastation. I deem it a WMD, definitely :)
so I ran some basic numbers based on your kerbal engineer data and your object of 1655kg going 5778m/s on impact of kerbin delivered 286,877,700 Joules of potential energy
I calculated 61 GJ of kinetic energy before impact, (3665kg @ 5773m/s), so a bit over 14 kilotons of TNT. That's a lot of stress on the accelerator (15.2 meganewtons for ~1.3 seconds). That's more force than 2 F-1 rocket engines!
You must have made an error somewhere. The quick estimate is: mass * velocity^2 / (9 km^2/s^2) = TNT equivalent The 14 looks right, but that would be tonnes, not kT.
the problem with that is the moment you shoot it, the station that shot it will be flying in the opposite direction. though at a slower pace due to mass and energy shit that I don't completely understand.
Seems like you could counteract that, somehow. Another mass driver directly opposite the initial one firing in tandem? Have to use something that breaks apart when fired, so you're not just shooting another rod out into the galaxy... Just spitballing.
Also a possibility. I'd initially discarded it due to needing to calculate the exact amount of thrust needed, with the right engines, and accounting for fuel, etc. Just seems simpler to counter the momentum of the shot with an opposite-facing shot.
its like an addiction to me to watch galileo i fell it in my blood wanting more i have watched the series 9 times over and over because lack of videos.. i am just an entity somewhere in space constantly eating time and space destroying worlds,stars entire solars systems... yea i will wait :) whenever scott can post it i will be happy :)
5:00 "There, we shot the Mun." Back in the 60's I had a game called, Shoot The Moon." It had just three moving parts, about fifteen inches long and weighed about a pound, pound and a half. Might still have it tucked away somewhere, and if so, still would be working just fine being made of sturdy wood and steel.
Use the railgun to shoot parts of a space station into orbit. Subsequent shots shoot it at the previous parts. In orbit when aproaching the previous part the station may need some assistance assembling them together. Magnetic connections may be the way forward. (magnetic field emission dynamics in orbit) MFED may be needed for controlled assembly . For parts that are susceptable to damage by the railgun can be implemented using conventional measures. eg: rockets
It's really frustrating, Open Broadcaster seems to do something to the windows audio settings and unless I go into them to reset them after starting OBS then the mic is just super loud. OBS has volume meters and they don's reflect this, it's very annoying.
Except that it used a conventional special gun instead of a magnetic railgun. God, the blast of the shot should be so terrifying that it should be seen and heard from dozens of miles away.
***** Fok if I kno. I use ehh.. "Stock Visual Enhancements", I believe it is called, (basically a variant of EVE) with medium settings and Scatterer (ya can find both on CKAN). With those two mods the game looks pretty much like this.
Nice job! I (tried) to calculate the impact force of your slug. It seems based on the numbers to the left (assuming they describe the projectile) that your slug weighs 3,600 kg and had a speed of around 6,500 m/s at the time of impact. Not exactly sure of the length of your slug, which is important for the impact time, but assuming a length of 1 meter at that speed the impact time ended up being 0.0003sec. With those values, I calculated the impact force to be 152,100,000,000 kg m/s^2 (N); or 0.15 terajoules (0.035 kt TNT). Not bad, roughly four times more powerful than the smallest tactical nuclear bomb ever built in the US. Maybe if you can achieve higher speeds you will get better impact forces, but even if you can achieve 20 km/s, you'll only make 1.45 terajoules, which pales in comparison to the 38,000 TJ yield of the B53 Nuclear bomb. So if you want to do real damage, you're going to need to fire a lot more projectiles, clearly.
Still have big problem with the saturation levels of the mic... :( And big difference of the volumes... You tend to scream regularly in the mic lately... Please think about your Headphone users fans. :)
daikuchar nothing to do with volume. Low frequency sounds are picking up harmonics from the higher frequency sounds causing total chaos to the sound & its quality.
daikuchar there's this nifty new feature with headphones. they come removable from the head AND the technology, so now you can listen aloud instead of whining.
daikuchar you know there is a volume thing on the video or on your computer and you can turn it down and up and it changes the volume like its so cool m8!!!
the mun people have a huge advantage because they are tidally locked and only need one with a huge hinge for inclination changes while kerbin needs multiple stations to be able to constantly fire and also more advanced rockets to get to the far side of the moon
For a 1600kg object with a 3kN ion engine means acceleration would equal 0.193125ms^-2. In 30 mins the space craft's velocity would increase by 347.625ms^-1. Not by very much compared to the initial 5500ms^-1. 6.32% increase in velocity.
You know what would be wierd? Is in 100 or 200 years when we as species collectively agree space is awesome and start building space stations even around Jupiter, that we send some space launch gunk off like the stages Scott sends into the void during the moon landing. Best part is those parts for our hypothetical future survive space long enough to orbit and maybe even reentry of some planet with intelligent life. Like we end up giving stone age equivalent aliens used up rocket boosters
It was about as powerful as the bombs dropped on Japan at the end of WWII. Not super powerful by today's nuclear weapon's standards, but would probably have blown out windows and maybe damaged sensitive equipment at the KSC 60 km away
+Skip6235 As Scott said, the impact was equivalent to about 7 tons of TNT. In comparison, "Little Boy" exploded with the equivalent energy of 15 *kilotons*... So no, it wasn't "about as powerful"...
When did he say that? On the livestream? Because it wasn't in this video. IDK, I did rough calculations for a 3665 kg projectile traveling about 6 km/s and got 17 kilotons. Granted, I could be off by an order of magnitude somewhere, since I did it really quickly. Anyone care to check my work?
shooting a rail gun without a firing solution is like shooting a quarter from 1000 yards away with a revolver while the quarter is moving a couple miles a second
MechJeb's landing autopilot panel will tell you how close your current trajectory is from the landing target. It even takes the atmosphere into account.
Even 58 km off, an object traveling at 6 km a second slamming into the ground would probably cause significant damage to that target. Mass Drivers. Hell yeah.
Revisit this thing with the Hydraulic rams from Breaking Ground, you can adjust your inclination on all 4 landing points to actually aim the LA after landing.
Mr. Manley, It looks like the Driver is upside down. the yellow shock triangle is supposed to have the base and the electric mark in in pointing downwards. Edit: this is at 1:02
This is terrorfyingly possible. Imagine a base on the mood armed with a railgun capable of firing to Earth. You wouldn't have to worry about the projectile losing much vilocity because of space so the only thing you would have to calculate is time
There's a story on fanfiction called talkins fist that is about plant earth vs the empire. In a chapter, earth used its remaining nuclear weapons and a 2 mile long rail gun to shoot down a star destroyer. It was one of the most epic moment I read!
If it was a telephone pole of titanium, the kinetic energy released would be equivalent to a nuclear detonation without the radiation after effects. nice aim BTW Scott, gg
I love the idea of sending this thing to the Mun and shooting back at Kerbin. It reminds me of a book called The Moon is a Harsh Mistress by Robert Heinlein. They were shooting chunks of the moon at Earth though. Perhaps you could try this but instead use a claw as the payload and link it to an asteroid before landing on the Mun. Show Kerbin that the Loonies or in this case Muunies aren't to be taken lightly.
So I clicked on RU-vid and saw this in my recommendations for the first time in a long time and I was like "Scott Manley?" "Oh yeah! I remember that guy. That man was my hero, he is what inspired me to look into astrophysics etc." And thus I clicked on the video to watch an old friend.
13:46 You know, this is probably the most accurate simulation you can get which truly grasps the gargantuan size of our earth and the thinness of our atmosphere. The projectile is going at 6km/s and yet in relation to the earth it isn't very fast. Once in the atmosphere it's over in a second.
Have you read Moon is a Harsh Mistress? This is pretty much how the rebellious Moon fights back against Earth. Metal containers filled with rocks launched from a mass driver.
