"The comet will be moving 40 times faster than a speeding bullet". I will now attempt to walk down the street while hurtling around the sun at 108,000 km/h - the speed of Earth around the sun. Sometimes NASA exaggerates difficulty by referring to velocity relative to a third object rather than relative velocity between the two objects. This project is very impressive already - no need to exaggerate. The probe has already matched the comet's orbit around the sun.
I have followed this project for a while. It is fantastically difficult to land the probe but Rosetta has already achieved the very difficult because orbiting this comet was far more difficult than orbiting, say Mars or Venus. Comets may hold a key to the evolution of the earth, so landing and taking samples is extremely significant. The last Mars lander was very impressive with the landing sequence that, at first seemed impossible and bizarre. This one is also far out but highly inspiring. I have read the comments below and have to admit that dumbing this great presentation down with imperial units and speeding bullets diminishes a little but hats off to the goals and science behind Rosetta and my best hope for success.
The comet is obviously gonna have very little gravity of which to attract and hold the lander in place. Hence why it has ice harpoons on it to hold it in place (but it looks like those ice harpoons have rocks to stab). So ive heard it likened to trying to keep yourself from floating off into space when doing repairs on the ISS. However the ISS has handles all over it. Rosetta doesn't.
Isaiah Phillip thats exactly what it would do ! but I guess they think we are to stupid to know that. These main stream scientist are really starting to disgust me
Rriddddicolously bombastic voiceover. Thanks NASA. Also, skip to 3:11 to see the animation answering to video title. ScienceCasts: How to Land on a Comet
Ridiculously difficult: Hitting the exaust port of the Death Star with a proton torpedo while evading turbo laser towers and tie fighters. Though it's another story with the force as ally...
It doesn't look like it was easy because the lander had a few clinches but history has been made. Let's just hope that the lander is secure and the science instruments work.
Having done a few hundred landing in the game Kerbal Space Program on various bodies, YIKES! This looks nuts, to land on a spinning object without a sufficient gravity field to maintain a relative position. Edit: mkay my bad, enough gravity to maintain a relative position on the plane of rotation. Slightly less scary, but still impressive.
porque nunca hay estrellas porque siempre tienen que estar donde hay mucha luz porque no se ve el escombro que saca el cometa nuca se ve nada de eso que mal desepcionan =(
NASA has never landed on Venus, that was the Soviet Union. And the landing on Titan was on a joint mission with the European Space Agency. We have pictures but no videos.
Salamihawk It's...complicated. And right now even tho it would provide a treasure trove of information on our planet past and future (of sorts) it doesn't pay off now, at this moment i mean.
As usual the narrator makes the mistake of stating the velocity of the comet (40 times faster than a speeding bullet) as if that makes any difference to the difficulty of the task. The lander is gravitationally bound to the comet, they are moving together at 40 times a bullet's speed.
A well done firecracker/rocket ... ;) can do this; 1$, 1€... Now I'm serious: I really hope they can do it! And that the data will be collected perfectly!! (Sorry, my english is not perfect this afternoon, usually it is..)
FonVegen Better yet step 1 find a comet & build cheap fake lander step 2 launch rocket with fake lander into outerspace step 3 fake dramatic landing to distract people step 4 cash out billions of dollars meant for actual comet landing that never happened step 5 much bigger profit shhhhhhhhhhhh
I don't think it's so much a problem of probability more like...calculated risk. I think. You have to take in to consideration the wealth of knowledge of both agencies, computer simulations and the fact that this mission is pretty much the equivalent of finding the Americas without a map or prior knowledge of where you should go. IMO.
***** . They have already done this dozens of times before, if you watched the entire 4 minutes of video. The Russians did it on Venus in 1966- Hello! We've had the technology for over a half century. When you have millions (billions?) of dollars to play [and well invested for human endeavors like this- not by Wall Street idiots] and with the worlds top notch scientists to help, you can do so much more than just waste time watching fantasy reality TV or making bad Wall Street Investments. I'll go out on a limb here because I am an astronomy teacher and I'm very excited about this for my students- it may be the most ground breaking mission ever in human history. They may discover something wonderful just beneath the surface. I'll let you guess what. . .
Mark Seibold If this feat is as difficult as it is said, every attempt should be humbly considered as a total new challenge. What Id like to really understand is what exactly means difficult once they have all the simulations and data support for the needed velocity, etc. I only imagine that it is the whole synchronization process and the capacity to adapting to variables. I hope they find water, organic compounds, etc or who knows.
Mark Seibold We've never ever ever fucking landed on a spinning comet before, get your shit straight. Try to actually pay attention to the video where it says why this is different than landing on say mars for example.
Is NASA/ESA preparing us for a failure? This mission has been on a month long delay, and now seems to be the most serendipitious thing to do. The orbiter can go around for a while, but the lander is doomed. Such a waste of taxpayers money...
Robert King robert,landed more then once on venus" russia soft landed,took photos each time but didn't have long because the atmosphere supposedly destroyed the craft's systems of communications fast. what's unforgivable is all the expense,time and effort they had camera's set up ONLY to take downward pictures towards the lander legs,no wide angle or outward across the land scape? WHY? should had ,5, or 6 camera's at keast' they are the least expense of the missions
monolyth421 Thy Baffled maze of cosmology! Churyumov-Gerasimenko Golf Master #14. "We landed Philae into a cave ". How convenient, first the engines went...the Big Boys can barely afford the truth about cosmos? ...Mimivirus created Thus, Thus made them, and Them shall un-Do Him...hehe was that deep or what :)
Well, why not? It is a terrific thought to imagine the problems or even the standard mission process. And bullets are the most commonly known fast moving objects that are there for comparison. So I think in this case it is not really wrong to use those examples. To make one thing clear: I am not American and I dislike their gun ownership laws. A lot. As well as their attitude to terrorism. But we shouldn't overdramatise it in this case.
Roger Keulen Well, thinking about the costs for the mission, and the embarassment that will definitely follow should the mission fail (And, of course, lead to further financial cuts and losses), everyone involved in the mission and/or simply interested in the outcome will probably be rather nervous until touchdown.
But what has that to do with terror and the speed of a bullet. It's a just American bullshit. Atleast try to explain how it's done, but that isn't intresting. Terror and bullet's are intresting apparently not science. The maximum speed wil be 3 feet a second. And it will have a ballistic trajectory, that's science talk for: _We don't have engines !_
Roger Keulen First of all, I know what a ballistic trajectory is. Next: What else can you compare the speed of a comet to? This is meant for public information, and not everyone here can imagine the speeds, distances and obstacles that wait in outer space. And "terror" is not only defined by "terrorism", but can also describe a state of intense fear and nervousness. Which will be present during the descent, no matter whether it can be controlled. I, as stated some comments ago, dislike the American policies just as much as you seem to, but I don't think there is a better (or easier) way of describing this mission to the average person, who admittedly, is not incredibly intelligent (and I am including myself here, since I know that there are almost infinitely many things that I do not know or understand, and lots of things I do and think are not correct and mere assumptions...).
already ?The last , as a result , still cite world maker casts a spell the earth is a person , Christ , Islam , Jew , as a result , cite a god is killing next , Obama and EU , still take an oath of a witness with a god stays , ? unexpected seek world maker meet ? , the world will have been calm.

It's technically not an exaggeration. Just a clever way to fool people who don't really know too much about space travel.

Good luck!
The comet is obviously gonna have very little gravity of which to attract and hold the lander in place.

So ive heard it likened to trying to keep yourself from floating off into space when doing repairs on the ISS. However the ISS has handles all over it. Rosetta doesn't.
I feel like launching the harpoons will just cause the probe launch upwards like a pogo stick.

ScienceCasts: How to Land on a Comet
I happen to find it a ridiculously well found perspective to enter the subject.
Then follow @ESA_Rosetta(beautiful daily pictures),@philae2014(for the lander itself), #CometLanding or plainly: #67P. These are on Twitter of course.
Hardly bombastic compared to how loud and obnoxious you have to be to get the attention of the masses.
Amazing thanks

Ridiculously difficult: Hitting the exaust port of the Death Star with a proton torpedo while evading turbo laser towers and tie fighters.
Though it's another story with the force as ally...
Well, at least it's bigger than Womp Rat.
aserta
True that!
I sincerely hope that it goes according to plan -- i don't think I'll be around for another attempt.
hope this goes well and the information comes home to earth it might help in the futuer
Good luck to this space mission !!!
Let's not forget about the numerous landings back on Earth those are just as difficult.
OH whew! And here I was going to launch my ship toward the sun for the gravitational whip, good thing this video set me straight!
I hope they accounted for strong Electrical discharge as landing occurs.
Good Luck !!!
i wonder how fast the comet is rotating?
Lo importante, no es posarse sobre un cometa, lo que importa es posarse y despegar con muestras de la superficie del Cometa y traerlas analizar
It doesn't look like it was easy because the lander had a few clinches but history has been made. Let's just hope that the lander is secure and the science instruments work.
does this work in KSP ?
Let's try regardless!
RoronoaZoroSensei See Scott Manley's video on Philae ^^
He tried it!
Having done a few hundred landing in the game Kerbal Space Program on various bodies, YIKES! This looks nuts, to land on a spinning object without a sufficient gravity field to maintain a relative position. Edit: mkay my bad, enough gravity to maintain a relative position on the plane of rotation. Slightly less scary, but still impressive.
mmmm and I have a vision now, I'm seeing the future ... breaking news!! comet is a rocky body, no ice has been found.
One black diamond? Two black diamonds? No, we're going TEN FREAKING BLACK DIAMONDS!!
Well, I think its an improvement that they are not talking about landing on a dirty snownall now.
Claudia Alexander = Storm from Xmen?
Philae Island back together with Agilkia , in space ! wonder when buildings will form.
Better contact Commander Shepard! :D
.. or recall Bruce Willis ...
AV Rescue
Nah, he a douche nowadays.
porque nunca hay estrellas porque siempre tienen que estar donde hay mucha luz porque no se ve el escombro que saca el cometa nuca se ve nada de eso que mal
desepcionan =(
venus and titan?? didnt know that..does nasa has landing pics or videos?
NASA has never landed on Venus, that was the Soviet Union. And the landing on Titan was on a joint mission with the European Space Agency. We have pictures but no videos.
We definitely need to go back to Venus and get some good photos. That must be amazing.
Salamihawk it rains acid there and the thickness of the atmosspehere makes it really hard to land. :(
On a note to that where are the pictures of siding spring passing Mars?!
Salamihawk It's...complicated. And right now even tho it would provide a treasure trove of information on our planet past and future (of sorts) it doesn't pay off now, at this moment i mean.

lol "mile wide knobs" hehe its funny because im british
Usually americans would say something other than knob, but I'm sure most of us would still get this not so funny joke.
It is like shooting a bullet at a bullet while riding a horse blind folded.
A well done firecracker/rocket ... ;) can do this; 1$, 1€...
Now I'm serious: I really hope they can do it!
And that the data will be collected perfectly!!
(Sorry, my english is not perfect this afternoon, usually it is..)
How difficult is it to launch an Antares rocket into orbit Nasa?
Great vid, although I still don't know how to land on a comet.
Step 1: Find a comet.
Step 2: Fly to that comet.
Step 3: Throw yourself onto the surface and apply harpoons to stay there.
Step 4: ???
Step 5: Profit.
FonVegen
Better yet
step 1 find a comet & build cheap fake lander
step 2 launch rocket with fake lander into outerspace
step 3 fake dramatic landing to distract people
step 4 cash out billions of dollars meant for actual comet landing that never happened
step 5 much bigger profit shhhhhhhhhhhh
***** I somehow have the weird thought that you really do not like me... I don't know where that comes from.
FonVegen
no, I agree with you, I was putting my spin on what you said ! you and I are on the same page here.
Aren't you glad it's not manned mission !
This is tripping me out
So ridiculously difficult that probability becomes bullshit.
I don't think it's so much a problem of probability more like...calculated risk. I think. You have to take in to consideration the wealth of knowledge of both agencies, computer simulations and the fact that this mission is pretty much the equivalent of finding the Americas without a map or prior knowledge of where you should go.

Yup looks like bs doesn't it? This is what people think when they don't understand science and math. It just looks magical!
I dont want to close my eyes...

Meters of dust? So what happened to the ice? Not a dirty snowball after all? EU FTW!
Is NASA/ESA preparing us for a failure? This mission has been on a month long delay, and now seems to be the most serendipitious thing to do. The orbiter can go around for a while, but the lander is doomed. Such a waste of taxpayers money...
Waste? How is this a waste?
Well screw you too!
NASA is not involved, at all.
i have a feeling its going to fail.
We have landed on Venus? I didnt know that!
Yip the Russians landed on Venus and took pictures
NicosMind Awesome! Just googled the pictures right now.
NicosMind
Wasn't the longest mission duration on Venus measured in seconds?
Joe Seph No the Russian lander stayed function with its coolants for nearly an hour before overheating.
Robert King robert,landed more then once on venus" russia soft landed,took photos each time but didn't have long because the atmosphere supposedly destroyed the craft's systems of communications fast. what's unforgivable is all the expense,time and effort they had camera's set up ONLY to take downward pictures towards the lander legs,no wide angle or outward across the land scape? WHY? should had ,5, or 6 camera's at keast' they are the least expense of the missions
"Seven hours of terror"? No. Maybe 6 hours and 58 minutes of yawning with a two minute ass-clencher at the end. Cool though.
Who figures this stuff out? Technology is getting way ahead of normal intelligence.

Typical American way to discribe spaceflight with 'Terror' and 'Bullets'.

To make one thing clear: I am not American and I dislike their gun ownership laws. A lot. As well as their attitude to terrorism. But we shouldn't overdramatise it in this case.
FonVegen There is almost no gravity nor a engine. Where does the terror come from. The metal spring ?
Roger Keulen Well, thinking about the costs for the mission, and the embarassment that will definitely follow should the mission fail (And, of course, lead to further financial cuts and losses), everyone involved in the mission and/or simply interested in the outcome will probably be rather nervous until touchdown.
