Routing Cassini through space to Titan - BBC

[xxxchris1891]

O my... If my brain is a star, I had just undergone supernova explosion....

[treemonster123]

i wish i could be an astronaut, but i hate physics too much

[dawebni]

the real reason we go on titan is for the oil & the gas as we've done everywhere else! it's time for the governments to stop lying to people!

[MeesterCrumpet]

@dawebni you fucking moron do you know how expensive it is to launch anything into space? let alone drilling equipment and people to operate them. god some people are truly delusional

[wuzheredontcare]

@dawebni stfu

[BKsMassive]

@dawebni

stfu french prick!

We went there because it's the only planet in our solar system that couple possible support life.

[kojimapie]

@dawebni .....oil only occurs if life was there millions of years ago. Plus if we did somehow manage to mysteriously find oil on Titan it would be fantastic! More oil, more flights into space, more exploration and the fact that life was there to be turned into oil in the first place!

[samharis122]

Hey my uncle helped built Cassini and before him his father and mother and maybe me so shut the fuck up about Americans

[funncubesde]

oh Nasa :D you made my day going better and better :D

[WaiWu]

Respect!

[VeritasTruthEmet]

Please tell me you still thinking 'walking on water' is a miracle after seeing THIS! If this is not a miracle then I don't care what is. I love science, I am in awe!

[elgranqenk]

Titan FTW!

[system0system0]

why cant they make videos of the planets from the ground or near the surfice.

They just make some shity pictures one cares about

[Boy75402]

@system0system0

There are only images from the surfaces of Venus, the Moon, Mars, and Titan. All of them are publicly available.

[sbergman27]

Oh for the day we have drives with enough total energy and specific impulse to just accelerate directly to the destination Star Trek style. Think thorium-based fission power combined with some sort of new high thrust ion propulsion. Beyond our current capability, yes. But not unimaginable.

[videowilliams]

True enough, sbergman27. I never knew Cassini needed that many gravitational slingshots to reach Saturn. Kinda reminds me of the way the old-time sailors had to do it, setting course for certain latitudes to put the best winds behind them, and having to set out at a certain time of year.

[sbergman27]

@videowilliams : We need to work on this. I'm 47, and when I read about missions like EJSM, I wonder if I'll still be alive to see the results. It's scheduled to be launched in about 2020 if all goes well. I'll be 57. It is scheduled to reach the Jupiter system in 2028. I'll be 65. There has to be a better way. And if we stop to do some work on proper propulsion, it may mean I never get to see anything more.in my lifetime. That kills me. But if it's what we need to do, it's what we need to do.

[CanadianCatastrophes]

jupiter is amazing... what a beautiful star system we live in... wonder how the thousands of stars we see at night look close up, and what their planets hold....

[rrfrprProductions]

CASSINI !!!

[ta2joe13]

absolutely amazing

[lejink]

try to imagine the planning it took to do this.. all the math, makes my head hurt just thinking about it.

[xxuncexx]

@lejink and can you believe those retarded americans did that?

[lejink]

@xxuncexx "those retarded americans" come from some of the most prestigious schools in the world. :)

[MusicalFan1701]

During a gravity assist, the velocity of the spacecraft with respect to the planet remains unchanged, but the velocity of the spacecraft with respect to the sun is increased. Cassini flew past Venus in 4/98 & 6/99, Earth in 8/99, and Jupiter in 12/00. The ongoing mission at Saturn has been highly successful.

[lukoshey79]

you must enjoy writing the same statement over and over, do you actually talk to these shamans or is it secondary knowledge. please ask the shamans where the beings of darkness came from before Huygans discovered Titan a few centuries ago.

[illuminatislut]

they say being of darkness are coming from the contraction dimension of Great Attractor. cheers! :p

[ClaudioCao]

cool

[ClaudioCao]

cool

[ClaudioCao]

it's so cool

[godlikeass99]

Cause you need to click on the text not the image

[ClaudioCao]

oh you suck

[farmerbb11]

Well, THIS video was a bust. I expected to hear/see an explanation of HOW the slingshot works. None of that, just that they "did it". A basic understanding of the law of conservation of momentum would say "Yes, if you approach a massive planet, your speed will increase ON THE WAY IN". But on the way out, wouldn't it slow down again the exact same amount ? You can certainly use this to change direction, but how does it accelerate the spacecraft on the way out ??

[blablubb12345]

The planets are not standing still, they travel around the sun. The probe is "carried along" by the planet while passing it. You can see that in this vid. On the other hand, the probe slows down the planet's speed around the sun a tiny bit.

[mR4342]

like gravity pull..i wonder how probe can go back to earth...

[ogicabp4u]

its something called "radial acceleration." You resolve the velocities towards the certre of the arc. The faster your car goes into a corner the more it will tend to be thrown outwards. If the centre of the arc (of that corner) had a piece of string attach itself to your car as you entered the corner and then released it as you come out of the corner it will have the same forward acceleration plus the radial acceleration.

seen the batman movie where the batmobile takes a corner at full speed?

[2canines]

interesting theory but there is a problem. to release the "string" would mean to release the gravity pull from the planet. that's impossible. i think it works like this.

the prob travels to a planet and get stuck in its gravitation and then it can chose in which direction to take off . if done correctly it will have its initial speed + some of speed the planet travels around the sun with

[ogicabp4u]

Indeed you are correct. But Its not a theory..more like a 'laymans explaination'. I couldnt come up with a better one that people might be familiar with. Point being that when the Batman Car swings round the corner it still has some of the velocity from its origional direction but more from its direction it is heading towards now...if you get what I mean? ie with reference to "initial speed + some of speed the planet travels around the sun with" Good point though!

[JMJSkits]

@2canines

I think that it might not completely get pulled in by the planet, because they are rotating, but just pull it around the planet a little and then release the gravity because it didn't get close enough(?) idk if i am right, you are probably correct

[xxxREDOXxxx]

do they have the need for speed carbon? kkkkk!

[BritneySpearsRox]

at around 1:14, is that actual, genuine video footage of jupiter? looks damn cool.

[tweet01uk]

the point i was trying to make is instead of spending billions on a space program all that money could have fed, clothed, housed people, gone into medicines for 3rd world countries, gone into technology development to stop or at least to decrease the increase of global warming gone into task forces government agencies etc to at least decrease the war in terror the list is endless the governments of the world need to look at home before looking into space

[link99912]

Yeeaaaa... I think universal understandance is more important then drug adicts and people who will probably attack us withen the next 200 years. Or maybe that's just me... See, the point is, the US makes... Well 14 trillion a year, spending a few billion isn't exactly terrible... As a matter of fact, we're spending a comofortable 10billion a month in Iraq.

[GOAQ]

"Spread life" is your message. We just look further. Some humans are quite clever. Just remove religion!

[dano9181]

Imagine if more people cared about space programs like this one. I think the world would be a better place. We gotta start looking at the big picture of life, and stop worrying about the small problems we have

[tweet01uk]

we need to concentrate on the problems of our own planet before we venture out into space the hundreds of billions of dollars/pounds other currencies spent on space programs around the world could have solved world hunger, stopped global warming (developing other technologies to decrease this problem etc), the war on terror, just 3 examples where monies need to be put into and 3 very serious examples too, the list is almost endless of all the problems facing our own planet

[dano9181]

the war on terror is an endless war and no one will win it, the war on world hunger is growing because its designed like that. we could have solved it decades ago but its manufactured like that for a reason. theres reasons why those people don't get fed and its not natural. and we are starting to become overpopulated too, thats another problem. by having less children around the world you can solve many problems like transportation, disease, food shortages, over filled schools, pollution,war,etc

[OkurkaBinLadin]

2 tweet01uk: Nonsense man. Those "problems" you listed either won´t be ever solved or other "problems" will arise.

If this mindset would be prevalent - humanity would still be stuck to Africa only. Hunting with spears, revering the power of fire and solving their "problems".

It´s ambitions of great minds, that are driving this civilizations. Not morons, that will need all resources for themselves just to keep afloat.

[GOAQ]

With respect, no respectable scientist is going to listen to someone who can't use full-stops/periods.<-- I understand your concerns, however religious warmongers slow the process. Space exploration is actually very cheap and a lot more fruitful than you may realize.

Religion and politics cause world hunger and global warming... not space exploration. War on terror saves your arse so you can comment...It would be nice to perfect life, but just incase...Spread life - increase the odds.

[tweet01uk]

if your all for the space program then why hasnt there been any new shuttles built in over 2 to 3 decades? why have we not gone to the moon again since the 60s or even landed on Mars? spread life increase the odds you say, common sense suggests to me then that we would try to look forward to colonise or even gain resources, of which we are running out of from orbiting bodies closest to us e.g. the Moon Mars etc we're only properly discovering Mars now well over 30 years after landing on the moon

[GOAQ]

The shuttle had a shelf life and missions to accomplish. They've done that and now we have new space craft on the way. The moon race was just that, a race. Political. We will be back there quite soon and using the cheapest safest way too. We will use the resources there too. But it's not as easy as just putting someone up there. There's a lot of ground work. We ARE talking space travel here! It IS rocket science. I wish it all moved faster but as i say religion and politics get in the way!

[calichic77]

aww! tats awsome "the slingshot" part =]

[Christobal777]

Finally Cassini-Huygens actually landed on Titan =)

[Christobal777]

7)carbon dating is designed to date things that are considered VERY old....it is not used for accuracy within 1-2 years (IE it has a 30 year leeway) it is simply used to identify around what time-FRAME something existed. (there are other processes to find the age of things less than 100 y.o.a.)

8) you are defeating the purpose of the "carbon dater" by asking him the age of something you already know and he most likely uses more than just carbon dating.

enjoy, and fear not of learning-its good4u

[Christobal777]

(2 refers to a satellite)

3)gravity is not a magnetic force, it's a force with variables of mass and distance

4)You do not breath only oxygen; a small percentage of air is oxygen, your body simply utilizes oxygen more.

5)Science does not say the universe is never ending; it simply states it is expanding

6)Carbon dating uses a specific isotope of carbon; to properly date something you must separate organic from inorganic through processes. (IE cant be done out of a lab) it's designed to estimate

[Christobal777]

|HarryCaray3000

Using a spectrometer you can effectively find the difference in energy levels of electrons by the photons they emit from one level to the next, these take the form of very specific wavelengths of colors that, when combined with a few select others, easily point to a single specific element. (you dont need samples) This technique is commonly taught in freshman college chemistry

2)Your comparing something 5600 light years away to something we orbited with a few miles above.

[HarryCaray3000]

I buried a cat in my yard near a tree 12 feet down. the reason i buried it 12 feet down was to perform an experiment to prove carbon dating wrong. i found the cat dead in the street at my house. my family planned for a pool for the next summer so they allowed me to do this. 11 months later the cat had been dug up during the excavation so i called a "carbon dater" who came out and looked for other crap dating to civil war time and told me the cat had been buried sometime in the 50s or 60s. ??????

[TheKazos]

Mate,

sftu,

Your obviously religious and thus closed to any other views and theory's. So please, go away and force your crap on someone else, someone who believes in an unproven ideal that only seems to lead to wars and suffering.

LOL i hads a serious moment ^^

Thank you.

[boltwared]

agreed what a fool, science has proven religion to be bogus shit.

[gynxor]

You paid just to have dead cat 'dated' and obviously hired the wrong people to do it. But you posted it on youtube and yet no major news organization spare fox news picked up your astounding discovery!

Guess all science is wrong and we must believe in what you post because you have so much more credibility than everyone else.

[HarryCaray3000]

i am sick of scientists trying to prove what they are saying when it is nothing but an intelligently put assumption. we found certain gases and forced and gave them our own names like gravity and nitrogen and oxygen etc. these are all theories. do we really know that a huge magnetic force is holding us to earths surface? or that the air we breathe is a gas called oxygen? or that the universe is "never ending"? or carbon dating?

[HarryCaray3000]

in 1998 scientists found a planet in a solar system 5600 light years away. they determined it to be the size of 300 earths and a gaseous planet much like jupiter. in 2006 the same scientists took another look and now decided that is planet is only the size of 19 earths and is a giant planet but is similar to mars. they dont know that nitrogen and methane are on this "titan" because we didnt land on it and take samples. the only thing that can be determined is that it exists.

[Deeciple]

Its interesting to think of the level of technological progression since the last century.

What we have is more people, more education / communication, which causes our knowledge to grow exponentially.

However advanced and complex future tech's require more and more research and I think we will start to slow down, until predominantely we are refining what we already have.

[markpacker]

Just remember that in the mid eighteen hundreds people wanted to shut down the patenting office since they assumed they had invented everything. Then suddenly steam technology emerged, and we've been booming since then. There's no telling what we may discover, and everything could take off again within just a few years.

[hullud666]

i want go Titan :D

[Frederik7318]

remember to bring a jacket, a warm one... and maybe a gassmask

[labrys71]

Well, technically Titan isn't a planet it's a moon of a planet.

[clintrocks69]

amazing

[bmwq7]

Thats alot of crap , try searching for " The Lucifer Project" and the youll all see what happends when casini hits jupiter , is never ment to go all the way to Titan , is ment to hit Jupiter so set it all in flames becomming our second sun ....have fun

[Ketzer22]

that's honestly the most retarded thing i've ever heard.

[lautann]

Your a retard. There are soo many things wrong with what you just wrote.

[FilmPA]

I wonder what it would be like to FUCK on Titan

[stensoft]

What the hell, you're mixing „2010: Odyssey Two" with reality. And you didn't realize that Casini is too small to ignite nuclear fusion on Jupiter.

[badguy66626]

hey go back to 2nd grade

[fatuesque]

The germans developed ufos back in the 40's...why arent they being used ?

Tesla developed free energy in the early part of last century,why sint that being used ?

People are being held back by governments and politicians.

[TracyMcSpacy]

cool

[fatuesque]

The human race is pretty pathetic,Using "sling shot" techniques in space because we dont have the technology to do things properly.

Do you think alien civilisations "sling shot" ?

NO

[csf969]

Your statement is limited in its viewpoint. All things must take time and be learned, and we must, as we always have, take small steps that will lead to bigger ones - enough steps make a staircase, buddy. We're not even close to where we COULD be, but think of how far we've come in only the last century. 100 years ago space travel wasn't even a reasonable concept.

[fatuesque]

I still say that we shouldnt bother using sling shot techniques and that we should focus on developing technologies that do things how we want to do them.

If we could go there direct then we would so it seems a waste of time for the worlds greatest minds to be focusing on techniques which are not ideal.

[johan28]

You mean project orion, dating back to the 50's and 60's?

[aeonflux67]

fatuesque...look at it this way 1904 or close the Wright Bros took off in that crappy little aircraft and went about 300m. Less than 100 years later and you are complaining that a space craft is using Jupiter to sling shot itself out of the Solar system. Dude...get some patience. Its called progress.

[budbadbig]

very cool video

[Jupiteroid]

Interesting...

[elongated1]

Wait is that my salad? i left it on jupiter

[hunjosdad1]

Right, none of that has anything to do with Saturn and the Cassini mission, take that BS somewhere else.

[LucabratZ80]

I wish I could be around in a few hundred years to see how the human race uses what we learned. Just think of the what we could do with all the resources in the solar system. How we could sculpt all these worlds without the fear of an ecological disaster.

They are all ours if we could all just work together.

[iv89]

wtf has this got to with aids?

[derekmb0000]

Lawl at mwalshy666 that is, cool video! =D.

[RonanG]

God bless the BBC! No one does it quite like they do. Long may they be free from the cold callous hands of politicians and privateers.

RonanG

[Gwygon]

nice done^^

[Norg1]

space exploration is very important to us to get off the Hell hole of a Rock called earth if we dont colonize the galaxy we will prob all die

[BeefInjection69]

Who cares about africa? If they didnt have so much sex there would be enough food for everybody and not as many people would have aids. Makes sense to me.

[dougie88is]

good on u Mwasahy666.

the millions of dollars spent by Bush and the US on the "War OF Terror" could have been spent to save the worlds people.

Who really gives a flying fuck about how far into space we can probe when 1500 South Africans are diagnosed with HIV per day. Is space exploration really so important that we let ppl starve and die on our planet to fund it?

Cool graphics tho ;)

Sponsor a child.

[JoeysTheMan54]

People in south africa should not have sex randomly or do anything else that could spread the disease. Obvioulsy by now they know the risks and the ways of it being spread. If they could think logically in the least they would stop the spread by eliminating the risks.

[mileswrite]

Actually the majority of people in rural Africa probably know aids as something like 'the death' or 'the sickness' and probably have no clear idea on how it happens, like London residents during the spread of cholera. These cultures are as much held back by traditional practices and tribal religious policies,

[mileswrite]

as they are carelessness; it's not so much random fucking like in europe or the US (where aids is being spread almost as fast) it's arranged marriages, men claiming ownership of women, gang rape - by soldiers from all around the world, also, not just africans... etc

[JoeysTheMan54]

Hmm, very good point. I say we should just quarantine everyone with aids on their own island. Then we wouldnt have to worry about it anymore.

[ImCool98]

yes it is important, what if we find something to help cure dieseases we cant cure yet. what if we find what we need from other planets?

[bucko60]

always blaming bush. those africans shouldn't have children if they can't take care of them.

[dragonwitgun]

if we could get to titan than just go to mars to save money

[rpgsftw]

....?

[CloudtheNxssEffa]

Mwashy666, If it was not for the principle of engaging in experimenting and or exploring, you would still be twiddling you thumbs and picking your butt. The US contributes the most out of any country towards philanthropy. Maybe some countries should grow up, get their acts together and stop relying always on the US to take care of everything. People will never attempt to reform themselves if they constantly expect someone to do it for them.

[Zodiaccaidoz]

American veterans have to eat out of dumpsters while we spend billions on space exploration we can't afford or to let Israel continue being the arse of the ME.

Then again, veterans aren't fighting for our proudernshit freedom anymore, so who cares about them?

Good on you, mwalshy666.

[RhinoRT]

mwalshy666 what a poor excuse for a human,I almost feel sorry for idiots like him/her/it whatever....if it were not for our service men and women idiots like him wouldnt be allowed to speak their mind (or lack of I should say)

[petecinc76]

mwaslshy you brainwashed liberal rag!! Go live in France you waste of space pantywaste!!

[dimthelight]

Ending poverty, and exploring the universe. That is what we need to do. cool video.

[mwalshy666]

you tit all this money spent on all this you could have fed the world. but i suppose its better than the ammount of money we spend on murdering innocent people using highly trained hitmen and terrorists(aka army navy ect)

[derekmb0000]

lawl.

[JoeysTheMan54]

The army and navy dont murder innocents. They are designed to protect freedom. That same army and navy gave you the ability to sit there freely and bash on people. So how about you show some respect for those who fought and died so you could freely sit your fat ass down and make comments like that.

[gcmuffinman]

Haha, I agree Supa. Cheers mate. And this video is badass.

[supatones]

stupidity is the most plentiful element in the universe

[Taolbi]

con't

there is a bigger picture to everything. i agree with you on the subject of money but we have to keep an open mind to any possibility

--------------------

This is in reply to

culturaldissident's post

[GmodPlusWoW]

Cont'd. Magnetic fields will be needed to contain the star, and high-yield solar panels will absorb the unfiltered, pure light energy emmiting from the star, converting it into massive amounts of electrical energy. However, if you used a HUGE diamond (3 kilometres in diameter), you could place it in orbit around a cold planet, like Mars or Europa, and make that planet habitable.

[BFGUITAR]

What the heck are you talking about? Id like to see how valid your facts are... link me up.

[GmodPlusWoW]

Just look up the science all over the internets, you'll find it. But not b4 I patent my process.

[sajeda123]

you stink dummy

[chadgra]

Nice idea but the energy needed to maintain a magnetic field strong enough to hold together a bomb would be immeasurable. E=MC>2 also When a hydrogen bomb is just this equation on a molecular level; imagine it with something 3 meters reaching critical mass. If that is even possible.

[GmodPlusWoW]

I know how to create a small self-sustaning fusion reactor. Just create a large diamond (roughly 3 metres in diameter), by extracting the carbon out of coal, and use nuclear energy beams (intense beams of gamma radiation made by exciting nuclear waste with electrons) to force the crystal into reaching critical mass. The diamond will then start to fuse nuclei together, creating a carbon star.

[Monocerios]

i agree mate so bad

[culturaldissident]

I have an idea! instead of spending BILLIONS on exploring Titan and the possible parallel of how life might have begun on Earth why don't we take care of life here on earth like the millions of children who go to bed hungry every night . Hmmm? I think a billion could go a long way to feed humans rather that the inhuman Trolls at NASA I guess it is pretty easy to spend money that doesn't belong to you.

[moffster]

i have an idea instead of complaining about nasa why do YOU go do something about poverty. idiot

[godlikeangel]

well only a little bit of that money might belong to you, and some people don't want to help those starving kids so don't bitch

[Taolbi]

some people's jobs are to help those in need and create a better life for people who are not as fortunate as you and i

and other people dedicated their lives to learning the sciences, and using their knowlege to explore space, that will hopefully someday bring about inhabitable places, new substances that have less effect on the environment or ultimately save the human race.

[baldingeagle666]

Explain to me that you know what the Cassini-Huygens mission research was for, and specify how many BILLIONS were put aside for the Titan exploration part of the mission.

Let's all stay cooped up and pretend stars and dreams don't exist, and make up some saga about what is up there like in the ancient times.

Troll.
