4 ly away, 47 years of flight time to get to high speed escape velocity. Oh yeah... sorry Hersen, we kinda developed new spacecraft like, 20 years after you left... we've made friend and cut travel time down to like, a month...
+Jonny Roberts Haha thanks. I'm filming an Eve mission at the moment but my laptop is struggling to run such a large craft at the moment, my game keeps crashing :( May have to hold fire on that project until I upgrade to a proper PC!
Matt Lowne It could be that blood memory limit, not the computer. Can't wait for 64bit, the memory limits so high that you might as well just call it unlimited. Oh and I like your new intro, bless After Effects and timeline keying.
+SSPS I heard...they hurt EACH OTHER! It's probably just a rumor though, they can't be that dumb can they? I'm sure Hersen Kerman will be back in a few millenniums to tell us all about them! It's not like anything bad might happen to him once he gets there...
+GenericSprite I've heard that they even intentionally kill millions of each other using huge exploding things that explode bigger than a whole space center full of rocket fuel! Surely my friend wasn't being honest though, right? Right?
what is scary about this is the final 10 seconds or so. This demonstrates the humongous distances of space quite well. All that velocity, all that fuel, and it still takes 10,000 years to get anywhere! Let's hope we find some spice somewhere...
+ObfuscatingUsername Those huge distances aren't insurmountable. Using a generation ship, it wouldn't matter how long the trip took, so long as it got there. Of course, it's possible to do the whole "just go faster" thing too, but it's not practical in KSP with only stock parts. IRL, we have theories for better rocket engines that would shorten the time to go 4ly down to something like 20 years or less. Examples, most powerful first: Beam-core antimatter rocket engine, Ramscoop augmented plasma core antimatter thermal engine, antimatter-catalyzed fusion rocket engine, fusion plasma rocket engine. Sure we don't have any working examples of these things, but we know that the basic phenomena behind them work. The sun is a fusion reactor, and we can produce tiny quantities of antimatter in particle accelerators. With fusion, the hard part is getting a reaction going at all due to the huge temperatures needed. With antimatter, storage is the hard part, antimatter reacts with ANY normal matter instantly converting both to pure energy (mostly high-energy gamma rays). For an idea of what would be possible if we got those kind of propulsion methods working, you can use the KSP Interstellar Extended mod.
He managed to reach the velocity of "only" 0.034% light speed, and since his ship can't "brake" he has only the ability to fly by another star system in a couple of thousands of years. Yup... distances involved are overwhelming.
That shouldn't be scary. The alternative would be SO MUCH WORSE. We'd be up to our necks in rogue planets, GRBs, supernovae, and stars crashing into us if celestial bodies were too much closer.
I wonder what the average time between something being introduced into the game (stock or mod) and that thing being used in asparagus staging. January 1st 2023: hey guys we added warp drives to ksp January 2nd 2023: *asparagus staged warp rocket to Andromeda in 8 seconds*
you could warp drive asparagus if you have a large warp drive with large energy supply, carrying a smaller warp drive with smaller energy supply. You dump the bigger one once it runs out of power, and then you fire up the smaller one. This way you could double your warp range, and decrease your travel time also.
i never said it wasn't for fun, i never said it wasn't a game, i said it wasn't JUST a game, i've learned more from my 60 odd hours in KSP about astrophysics than i did in school for the whole time i was there. it's impressive to do things in this game due to the knowledge required, that's why it's amazing; it amounts to no real world achievement, but it's still a challenging task.

Simply breathtaking. How did you do the staging during the Ion burn? I.e. did you just set a reminder for when the next staging should happen or did you use a mod to do it automatically?
No reminders no mods, I had to pay attention all the time - since all ion engines draws fuel from all xenon tanks (fuel pipes dont work) I had to block fuel in all tanks exept the active aspargus stage, and when that was ejected unblock the next stage. Also had to constantly angle the solar panels - to much sun exposure and they would produce negative current, too little meant less thrust . However with 4 x time acceleration the burn was "only" 3 hours.
***** Orbiting Kerbin at 17 km/s is impossible. Once you reach that speed you are on an escape trajectory. The 2km/s and 7km/s figure I mentioned is at LKO (Low kerbin orbit) and LEO (Low earth orbit) respectively.
"Strange creatures with very small heads only 4 light years away" Just in case you don't get that, Humans live 4 light years away from Proxima Centaury... So he's basically saying they're going to see us humans from Proxima Centaury... I might be wrong
escaping the suns gravity while overheating reminded me of that scene in Interstellar where the endurance was trying to use the black hole's momentum to get to the last planet...
How to get more delta-V on this cheaply- 1. More efficient engines (like an SSME, or aerospikes. 2. Larger Ion Stage 3. Unmanned Craft 4. Making the overall rocket smaller, and/or expanding the "payload" of the NTR and ION stages, so that the NTR and ION stages do all of the in-space burns, rather than the chemical engines starting them, as in this video....
+Ian Brandon Anderson Where would aerospikes have been better? On the first stage they would have driven the part count up for very little benefit. On all subsequent stages they would have been worse.
“Kerbol” is a fan-made portmanteau of “Kerbal” and “Sol” - the Latin name for the real-life Sun. Before version 0.11, which introduced an object for KSP's parent star and an orbital Map view where it was explicitly named, it was an unnamed directional light source at infinite distance. Fans on the KSP forums invented and popularized the name. According to the wiki
This was hilarious. I love how Hensen was sitting in his little one-Kerbal capsule for 45 years while he waited to complete that long orbit around the sun to get close.
My fastest ever screenshot is 88,888.9 m/s with a tiny sattelite that still had like ~310 liquid fuel and a LV/N and after separation an ion engine with 1400 xenon in it. But I used it to break and lower the orbit around the sun instead of accellerating further. Well, I think you cannot get to ~5,500 km above Kerbol any more without melting. :P
WOW, do you have a craft file available, if so can you please upload it to somewhere we can access it, you've made something amazing here, not just for speed but I didn't recognise half the parts you used! you are either very talented or I have less than 5 hours in kerbal, good luck for future projects!(I doubt you'll need it)
The gravity assist and rocket are both pretty realistic. But even if nasa did find evidence of life, they wouldn't send a manned mission. They would send an unmanned probe to the system. And they wouldn't wait thousands of years. They would try to develop technology that would make the probe get there in a couple of decades or less. Then after that, they would do a multiple hundred person space mission that would take several decades to a few centuries. They would never send 1 person crew to represent humanity. No human has ever gone to space alone since the 1960s.
+Acre ! There is talks about sending very small crafts to Alpha Centuri using lasers to push it to 25% of the speed of light. So it would reach within a century.
The most feasible way of achieving this with current technology is thousands of nano probes with solar sails each propelled by kW lasers on Earth. They'd reach something like 20-30% the speed of light where even a stray hydrogen atom could decimate the craft, hence the need for a swarm.
Very nice! the most impressive thing about this is your patience in my oppinion! :) I'm pretty good at building things that would work if only my patience would be on par with the build quality.
To get to the Sun faster you can use Jool to perform a gravitational assist braking maneuver so that you basically fall into the Sun after passing in front of Jool. This maneuver can be pretty fuel efficient too.
I think the video creator means overheating. If they were directly facing the sun at that close distance they'd absorb more heat (I can't explain why, but I think this is the case) and wouldn't be able to radiate it away quickly enough. The panels were kept at an angle so they could power the ion drives without melting.
Glad you liked it :) Getting the look i wanted and still make it work well as a launcher was surprisingly difficult . It was a nightmare to get rid of the wobbling .
I managed to get to 104km/s with like 15 followed up single-tank stages of xenon for final acceleration and heavy abuse of jool gravity assists, wondering if with the more efficient sundive strategy it would be faster (I did mine in the outer solar system because aiming at a target is easier that way)
Once i wanted to land my SSTO, but it got destroyed and the cockpit bugged out of the planet. Then i moved with the max speed far away from the sun. The number of the speed was so high that i couldnt see it all. Like few quadtrillion m/s. I made some screenshots and clips lol
ive reached speeds which absolutely dwarf this, 1. get an advanced grabbing unit 2. set pivot freely and spin in circles 3. time warp then go back to regular time The game will have a seizure and u will fly out of the solar system at 100x this speed
That was ridiculous. I've been playing for 2 years and just fuckin' figured out that you can click all those neat SAS symbols to the left of the navball. Facepalm
Dude, can I give you a tip? Your titles are way to fast to read. Studied film at uni. The rule they taught us is that if you can read it to yourself quickly 3 times, then that's the right length. Literally couldn't follow this video.
It hit the distant planet at over 100k m/s destroying its atmosphere and everyone on planet. The now devastated race is building a ship now to destroy Kerbin in response. Going to do my own and see what happens. Does their solar system have a limit.
Theoretically you might be able to get better full to dry mass ratios by bringing ore tanks and converting to xenon as you use it. the ratio for xenon tanks is 4 but the ratio for ore tanks is 8.5
Isn't this the same trick they did to create escape velocity from the black hole in Interstellar? Get real close and burn like almighty hell to maximize oberth effect.
the answere on more gravity is moaaar boosters :D , very more boosters, and or probably anti mass if it existst, the mobile production would make hyperlightspeed possible another question would be, if the time would stand still or it can happen only if there is an extreme mass
I think the only problem we have is that we don't have enough technology. To reach that interstellar orbit I'd reccomend the EM Drive (microwave engine). I won't tell you evereything about that, but it's more efficient of engines, that we invented. It's using only ElectricCharge to work, Ion drive also uses it, but Xenon, as well. There are numbers: If we'd test them in zero gravity and drag the Ion Drive will make the speed of, if I renember it well, 0,019c (c - speed of light (~300 000 km/s)). The EM Drive: 2/3c. That's a big number!
