An average ksp player could plot such multiple gravity assist in an afternoon considering the simplified two-body model used by stock ksp.If you consider the multi-body model that would take mouths,not to mention the difficulty to set up fail-safe plans
Love how we're still talking about Voyager almost 50 years later - shows the intelligence (and some luck) of the engineers and team members! Keep trucking Voyager!!
Voyager 2 arrived at Jupiter 1.4 seconds late and only 60km off course! Simply amazing! Till this day, I still watch Voyager 2-related videos. This probe has a special place in my heart.
Fun fact: Voyager 1 was launched almost at the same time as Voyager 2 and was also capable of making the full four-planet tour but it was deliberately directed to take a much closer look at Saturn's moon Titan instead because of the unusual properties of that satellite. (it's the only moon with substantial atmosphere) This trajectory made it impossible for Voyager 1 to continue on to Uranus and Neptune.
The "Grand Tour" was only an option. Voyager's original mission was Jupiter-Saturn-Titan. If V1 failed at Titan, NASA & JPL would send V2 to perform the same Titan rendezvous. It was V1's success @ Titan that allowed V2 to complete The Grand Tour.
The nasa engineer that discovered the alignment is my great uncle, Gary Flandro he just turned 90. I’ve met him several times he’s a cool guy, he told me that they even used some of his hand calculated trajectories in the final launch
The Voyager probes are probably my favorite "space ship". They were launched when I was still quite young...sadly too young to really remember. They've been with me my whole life, and frankly are one of the reasons that I have been fascinated my entire life by space and science in general. Soon my friends will go silent as they continue their eternal journey, and I will miss them terribly.
Even better now. Orion spacecraft have most advanced navigational system as for this day, and that was one of main things to test. Probably more important then whole Artemis program.
Thank you so much! Truly an amazing journey to learn about and I'm so glad you enjoyed my explanation of it all. Cheers and thanks again for the support!
5:35 The Voyager Probe knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the probe from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the probe is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the probe must also know where it was. The Voyager guidance computer scenario works as follows. Because a variation has modified some of the information the probe has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
Honestly, I have a lot of confidence for the starship tests. I feel like all will go pretty well. At worst probably some error that will delay the starship for like half an hour, but nothing too bad. There could also be the possibility of superheavy landing incorrectly, which we’ve seen many times before with the stages of falcon 9.
Starship will only work as an interplanetary transport. It’s too big and will be too heavy to land on mats without slowing down massively along with huuuuuuuuuuuuuuge parachutes since Martian Air is so thin. Honestly the money would be better used to create a mobile space station in an figure 8 orbit between earth and the moon
@@jaythekid4728 "starship will work as an interplanetary transport" uhhh that's what going to mars means? Also it doesn't have to rely on parachutes given how it's already rocket powered. If it can land on earth, it most definitely can land on mars too
@@jaythekid4728 A parachute would need to have around a 350km radius, if entirely reliant on the parachute, whereas the Starship could just land as designed. Did you know that it was designed to be interplanetary? It's not going to find it much more difficult to land on Mars, and slowing down is accomplished in the same way it speeds up at the start of the mission - being precisely the same mechanism. Fuel is the main issue, so it will refuel at StarGas1, StarGas2, and StrGas3. This will give it enough to complete it's one-way mission, to then either get stripped and used for materials, or refueled for a later trip/lifeboat, etc. Or just a place to chill out when the weather's a bit glum.
@@jaythekid4728 How would that even work? You know the moon isn't stationary relative to Earth, right? (I know I sound like an asshole but I'm genuinely curious)
The amount of tech involved is just amazing. It isnt just a piece of metal flung into space, but a complex piece of machinery flying with extreme precision!
I discovered your channel just now, and this video told me everything I need to know about your channel. The way you explained everything was so simple, yet so effective. It’s insane how they figured out complex space science/math back then, can’t wait to see what the future will hold. Relating to starship, I think the flight test will go somewhat smoothly, since they have experience with the falcon boosters. Although, I’m sure some problems will arise, but making mistakes is all part of becoming better!
Thank you so much! I'm so glad that you enjoyed this video and thank you for sharing your predictions as well. Good luck in the giveaway and welcome to the community!
Only by mentioning the 42km/s threshold can I really wrap my head around the brilliance of Voyager 2's travel. It managed to escape that much pull and is still somehow moving at a constant 17km/s
The more I learn about Voyager (and I've been around since the launches!) the more I recognise that this mission is a feat of extreme space engineering genius. For different reasons, clearly, I truly believe it matches Apollo.
What a great video! I am a Ph.D student in Aerospace engineering and gravity assist design is my area of research! You did a great job summing it up into a nice easy to follow video! Also I think the starship launch will go really well but there will be some sort of a failure on reentry
As a kid I'd watch the science channel and be entranced by shows half as thorough as this channel. I can't believe we live in a time where we can watch and learn things like this in an instant, for free, whenever we want
Actually mind blowing the amount of calculations that went into this program, and I'm so glad that it was a success. Hopefully starships first test flight will be as big a success as Voyager 2 was.
In a planet where we lose our deliveries , there also exist such minds which can execute journeys non-comprehendable by the common person . Absolutely magnificent . I just revisited the “Pale Blue Dot” photo , and it shows just how tiny we are
Beautiful graphics and animations in this video, as well is a focus on technical specifics on Voyager 2 that I have not seen in other videos on Voyager. Well done Primal Space!!
I always knew the Voyager mission was special but this video was so well made that I am even more impressed with the voyager mission. The self correcting Gimbal system is absolutely fantastic. Regarding the upcoming Starship tests, I think they will go well since it is a pretty expensive project, could be a few delays to get things right but I can't wait to watch it!
as a kid i was amazed to see voyager 1 and 2 on the school's library encyclopedia as it passes different planets. 30 years have passed and only now have i realized the complex math involved to navigate it, the time constraints on launching the probe on a rare planetary event, not mentioning the limited technology at the time to achieve such an incredible feat. Watching this gives back that amazed feeling i have 30 years ago...
These two spacecraft are eternal. They are indestructible. Electrics that have evolved into state of the art electronics. The batteries and solar panels have also evolved to a better model. One of them learned how to turn itself back on while performing surgery on itself. Now I’ve learned that all the photos are altered by a artist’s imagination none are all natural. The radio equipment must had had several backups so it could keep sending terabytes of information for 50 years. One hell of a Wi-Fi connection.
The distance traveled by the Voyagers seems incredible to us, but it will never be compared to the distances between stars or galaxies, let alone the size of the universe. Thanks for the interesting video.
I keep hoping there will be videos about the Pioneer 10 & 11 missions. Many people don't even know about these spacecraft that were launched five years before the Voyager missions and are also somewhere outside of our solar system.
The accuracy and precision of all systems while working together is insane, one mistake could have turned this mission into failure. just crazy engineering.
I think Starship's first test flight will go smoothly with minor issues. But if it doesn't, it's still a success as that "failure" or "rapid unscheduled disassembly" will provide valuable lessons and insight for SpaceX for the next line of Starships. Overall, an exciting event for Spaceflight. The most powerful rocket of our time taking off.
I think Starship will have a good launch but the landing might be a bit hard. Not a crash but not as smooth as they would expect. Thanks for another awesome video !
The spacecraft knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation.

Awesome video! Super excited for Starship’s first launch, hoping with all my heart that it will go well. Given the amount of time and effort so many people have put into it, the launch should go well. The physics of it are crazy, but I’m so excited to see its wonders of engineering roar to life. Hopefully it can complete what it’s meant to do, and allow humans to travel to the moon, mars, and beyond. Every time I see a photo of Starship it just amazes me at the amazing things humans are capable of, and what our future could be. Go Starship!!!!!
I love the optimism and I'm hoping for the best as well! Thank you for sharing your predictions and so glad you enjoyed the video. Good luck in the giveaway!
Ok I'm facing it. I'm a CS major student and astronomy is one of my minors because of calculus and stuff. But still even thinking of something that complex and precise, it's mind boggling!!!!
It's incredible to me that gravity assists can provide so much extra energy. I'm sure this is discussed abundantly, but this very much appears like a source of endless free energy. I guess it just appears that way because these planets are so massive we don't think about how Voyager changed their orbits by pulling on them. :D
This is by far the best video I have seen on the internet explaining the voyager mission. They are still going strong for the most part. Maybe some day something will find it.
I think the Starship launch will go pretty well. The space enthusiast within me wants to expect a positive outcome and a successful mission but I am little bit skeptical on the landing part tbh. Kudos on amazing work Primal Space 🚀
I really think that the starship mission is going to be a huge success BUT it may be delayed a bit(not a lot like Artemis) either due to minor inconveniences or the weather. Now we just have to wait and watch to see what happens. Got my hopes up for this one🤞
@@primalspace Very informative video btw. I learnt a lot of new things about the Voyager spacecraft especially its navigation part. Thank you so much 😁
I think starship will successfully launch into low earth orbit, but won't go any further. Hopefully it completes the whole trip though. I love your work primal space 🚀🌌
My two mayor concerns about the starship launch are the reliability of the 33 engines in the first stage and the heat shield. Dunno, but seeing how every static fire one or two engines shut down, makes me worried. But they made some big improvements on the heat shield, so Im not as concerned... Thanks for making all these giveaways! Can I ask how you pick the winner?
ABSOLUTELY mindbogglingly astonishing job of those guys back in the 70s at NASA. The step by step precision of their immaculate calculations is a testimony to their utter dedication and unparalleled passion. Makes me proud to be a human, even though on a completely another level. 👏👏👏
The technology back then to accomplish this is basically the same we use today for spacecrafts. We still use gyroscopes, we still use liquid fuel for propulsion and to correct course, we still use the same math and Newton's laws of motion to guide these spacecrafts. We still use the same Plutonium designed powered battery. The only so called "advancement" is faster computing power which is not necessary to do these simple maneveurs. 2021 NASA’s Perseverance rover has a 1997 computer chip brain. Here’s why. It may be old tech, but it's super-reliable.
Not nearly enough is said in the mainstream media about these two amazing spacecraft. The engineering and navigation is just stunning for something designed in the early 70's. I've was just 11 when they launched in 77. To think they are still sending data back 45 years later is mind- blowing. Respect to the engineers of the time.
Personally, I think that during the Starship test flight it will all be OK until a certain moment, maybe a few minutes after launch, when a fatal error will cause it to go off course and crash. Nevertheless, I hope that doesn't happen, even though I think that (or something similar) will
@@primalspace I did a couple calculations, the fastest voyager 2 went was mach 116.6181388! Whats crazy is this is only 1/3rd of the parker solar probe which went around mach 369, Voyager 2 had a top speed of 89477.50001879 mph and the parker solar probe had a top speed of 300,000mph. Insane to think about if you compare it to the speed of light its 0.00132718 or 10thousandths of the speed of light!
@@visione6720 the parker solar probe doesnt technically have a speed. it has an average speed, but because its orbit isnt circular, the speed difference between perihelion and apohelion is quite high
This is the first time I've come across this channel and was trying to bail to home as soon as you said "used giant magnets" before I realized that was as smooth af ad transition 😂
🤣🤣🤣 Sorry to catch you off guard like that! Glad you got some enjoyment out of it though and I hope you enjoyed the video as well. Welcome to the channel!
Love dreaming about Voyager 1 and 2 and imagining their travels. They are one of the only ways for us to try to comprehend the vastness of space. I am always amazed at how empty our solar system is and how tiny all of the planets and comets etc really are compared to the space around the sun, and really, how small our sun and solar system is. I love hearing things like Voyager 1 will not approach the next nearest star for another 40,000 years. Wow, and thats only a scant spec of space within one galaxy.
I completely get where you're coming from. It seems like the more I learn, the more incomprehensible it all becomes. Mind blowing stuff, but I can't get enough! So glad to hear that you share my passion and have been enjoying the videos!
Incredible video on the Voyager. For Starship, I think they will have less than 100% propellant loading and 90% thrust just like the previous static test fire and carry low to no payload and try to achieve orbit. It will all come down to stage separation and second stage engines ignition at that point. So thrilled and can't wait

I keep hoping there will be videos about the Pioneer 10 & 11 missions. Many people don't even know about these spacecraft that were launched five years before the Voyager missions and are also somewhere outside of our solar system.
How the hell did we figure this stuff out 😮
he legit explained it

@@NEKOSAIKOU. no shit
@@vedpatel8365 why are you asking then
The voyager knows where it is. The voyager knows where it is because it knows where it isn't.
Voyager is truly amazing
Absolute props to every single person who worked on it
The accuracy and precision of all systems while working together is insane, one mistake could have turned this mission into failure. just crazy engineering.
You lost me within the first 10 seconds. RIP Pluto.
Dicks out for pluto
I think Starship's first test flight will go smoothly with minor issues.
But if it doesn't, it's still a success as that "failure" or "rapid unscheduled disassembly" will provide valuable lessons and insight for SpaceX for the next line of Starships.
Overall, an exciting event for Spaceflight. The most powerful rocket of our time taking off.
Haha, way to hedge your bet.
@@Hawk7886 Yep
At least they now know a lot of issues lol
I think Starship will have a good launch but the landing might be a bit hard. Not a crash but not as smooth as they would expect. Thanks for another awesome video !
I could definitely see that being the case. Thanks for sharing and so glad you enjoyed the video. Good luck in the giveaway!
i honestly did not expect the sudden sponsorship. Never let them know your next move
Haha sneaky like that 😂
The spacecraft knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the spacecraft from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is.
Awesome video! Super excited for Starship’s first launch, hoping with all my heart that it will go well. Given the amount of time and effort so many people have put into it, the launch should go well. The physics of it are crazy, but I’m so excited to see its wonders of engineering roar to life. Hopefully it can complete what it’s meant to do, and allow humans to travel to the moon, mars, and beyond. Every time I see a photo of Starship it just amazes me at the amazing things humans are capable of, and what our future could be. Go Starship!!!!!
I love the optimism and I'm hoping for the best as well! Thank you for sharing your predictions and so glad you enjoyed the video. Good luck in the giveaway!
I don't care about Neptune I still think of Pluto as the farthest planet!
I think a lot of us still do!
Fascinating stuff on the voyager though. Can you do some more on it? Specifically how, and what it's doing in deep space?
I'll definitely add that to my list of requests. Thank you for the suggestion!
This whole operation was just so badass. The people who did this are heroes of mankind, propelling us forward into the future.
Agreed!
Ok I'm facing it. I'm a CS major student and astronomy is one of my minors because of calculus and stuff. But still even thinking of something that complex and precise, it's mind boggling!!!!
Wat an incredible masterpiece
It's incredible to me that gravity assists can provide so much extra energy. I'm sure this is discussed abundantly, but this very much appears like a source of endless free energy. I guess it just appears that way because these planets are so massive we don't think about how Voyager changed their orbits by pulling on them. :D
20 years journey and he arrived right on time. Just 1.4 secs late. Kudos to those scientists they are the real alpha males
Kudos is right!
I love how voyager 1 was just "Go away", while voyager 2 was "You need to be super precise with 1970s tech"
This is by far the best video I have seen on the internet explaining the voyager mission. They are still going strong for the most part. Maybe some day something will find it.
I think the Starship launch will go pretty well. The space enthusiast within me wants to expect a positive outcome and a successful mission but I am little bit skeptical on the landing part tbh.
Kudos on amazing work Primal Space 🚀
oh well....
Voyager 2 is quite literally the coolest thing done by humanity. I don’t think anything is topping this.

the missile knows where it is by knowing where it isn't
lol
I cant believe i only discovered your channel now, shall start binge watching your videos!
Thank you so much! So glad you're enjoying the content. Means a lot!
I am French and I discovered your channel not long ago. It's really super interesting, I love your videos keep it up.
Thank you so much! So glad you're enjoying the channel!
I really think that the starship mission is going to be a huge success BUT it may be delayed a bit(not a lot like Artemis) either due to minor inconveniences or the weather.
Now we just have to wait and watch to see what happens. Got my hopes up for this one🤞
After these delays I'm really hoping everything goes well! Fingers crossed!
@@primalspace Very informative video btw. I learnt a lot of new things about the Voyager spacecraft especially its navigation part. Thank you so much 😁
I think starship will successfully launch into low earth orbit, but won't go any further. Hopefully it completes the whole trip though. I love your work primal space 🚀🌌
My two mayor concerns about the starship launch are the reliability of the 33 engines in the first stage and the heat shield. Dunno, but seeing how every static fire one or two engines shut down, makes me worried. But they made some big improvements on the heat shield, so Im not as concerned...
Thanks for making all these giveaways! Can I ask how you pick the winner?
They were just testing the engines auto abort mode ..
So it was partially intentional ...
@@nirbhayatiwari5425 and why did they replace some engines after every static fire where some engines didnt fire?
@@astronautnr7 Only one engine was replaced which was shut off prior static fire ...
The engine which was auto aborted was not replaced ...
ABSOLUTELY mindbogglingly astonishing job of those guys back in the 70s at NASA. The step by step precision of their immaculate calculations is a testimony to their utter dedication and unparalleled passion.
Makes me proud to be a human, even though on a completely another level. 👏👏👏
The technology back then to accomplish this is basically the same we use today for spacecrafts. We still use gyroscopes, we still use liquid fuel for propulsion and to correct course, we still use the same math and Newton's laws of motion to guide these spacecrafts. We still use the same Plutonium designed powered battery. The only so called "advancement" is faster computing power which is not necessary to do these simple maneveurs.
2021 NASA’s Perseverance rover has a 1997 computer chip brain. Here’s why. It may be old tech, but it's super-reliable.
Not nearly enough is said in the mainstream media about these two amazing spacecraft. The engineering and navigation is just stunning for something designed in the early 70's. I've was just 11 when they launched in 77. To think they are still sending data back 45 years later is mind- blowing. Respect to the engineers of the time.
Agreed. Absolutely mind-blowing and inspiring as well in many ways!
Personally, I think that during the Starship test flight it will all be OK until a certain moment, maybe a few minutes after launch, when a fatal error will cause it to go off course and crash. Nevertheless, I hope that doesn't happen, even though I think that (or something similar) will
0:02 Pluto receiving no love
I know. It makes me sad too 😢
@@primalspace I did a couple calculations, the fastest voyager 2 went was mach 116.6181388! Whats crazy is this is only 1/3rd of the parker solar probe which went around mach 369, Voyager 2 had a top speed of 89477.50001879 mph and the parker solar probe had a top speed of 300,000mph. Insane to think about if you compare it to the speed of light its 0.00132718 or 10thousandths of the speed of light!
@@visione6720 the parker solar probe doesnt technically have a speed. it has an average speed, but because its orbit isnt circular, the speed difference between perihelion and apohelion is quite high
@@Messier42-handle Jeez if thats the average, i wonder what its top speed was
@@visione6720 top speed at perihelion of orbit is 692000kmh and it gets faster with each time it has a gravity assist with venus
looking at real photographs of space fill me with such a profound sense of dread and awe at the same time.
Same!
This is the first time I've come across this channel and was trying to bail to home as soon as you said "used giant magnets" before I realized that was as smooth af ad transition 😂
🤣🤣🤣 Sorry to catch you off guard like that! Glad you got some enjoyment out of it though and I hope you enjoyed the video as well. Welcome to the channel!
I keep thinking about all that compute power back then was probably less than that of the phone that Im watching on rn
Right? Pretty mind blowing when you think about it.
4:05 - Moment of joy for Flat Earth lovers
Yo. Pluto is still a planet to me.
Love dreaming about Voyager 1 and 2 and imagining their travels. They are one of the only ways for us to try to comprehend the vastness of space. I am always amazed at how empty our solar system is and how tiny all of the planets and comets etc really are compared to the space around the sun, and really, how small our sun and solar system is. I love hearing things like Voyager 1 will not approach the next nearest star for another 40,000 years. Wow, and thats only a scant spec of space within one galaxy.
I completely get where you're coming from. It seems like the more I learn, the more incomprehensible it all becomes. Mind blowing stuff, but I can't get enough! So glad to hear that you share my passion and have been enjoying the videos!
Voyager is example of science unmeasurable by length and width.......
Hat's off to those who make it measurable ....
Agreed. It's all pretty amazing to think and learn about.
Neptune isn't that blue by the way
You been?
1:55 where is mars??
We don’t talk about him…
It's where Venus should be, which is where Mercury should be, which doesn't exist in this diagram 💀
We got rid of him

*Record scratch plus ad starts*
Just kidding
@@bluey-next777😅😅
The amount of precision needed for something like that to be done would be astronomical and somehow we pulled it off!
Pretty mind-blowing when you think about it!
Amazing!!! The people who designed these are geniuses!
💯💯💯
Where the flat earthers at? 😒 😂
Oh they're here haha
Honestly the precision to do this is just so incredibly high.
Pretty mind-blowing to think about!
It’s just amazing how we were able to leave the solar system.
So true. I can't wait to see where we go and what we discover next!
Incredible video on the Voyager. For Starship, I think they will have less than 100% propellant loading and 90% thrust just like the previous static test fire and carry low to no payload and try to achieve orbit. It will all come down to stage separation and second stage engines ignition at that point. So thrilled and can't wait
I had never looked into how positioning and orienting systems work for space probes, and this clear explanation blew my mind. Thank you!
