i was deeply obessed with this video and mars rovers as a kid, rediscovered this video a few yrs ago and every once in a while I return to watch it and heal my inner child.
Those are people who worked hard their entire life because they WANT TO KNOW whats out there in our universe, they just DONT WANT TO STAY with the doubt.. people who decided not to party or play video games and instead they studied to learn more and more. Proud of those people
This video is very nostalgic for me. When I was a kid I used to stay up late to watch NASA launch rockets and exploring NASA website. Scoping the ISS. Man, how I loved space exploration as a kid.
Fundamentals of Electric Circuits 5th edition brought me here too. Actually, this is my 1st semester of Engineering . By the start with something like this is really inspiring.
WALL-E (promoted with an interpunct as WALL•E) is a 2008 computer-animated science fiction film produced by Pixar Animation Studios and directed by Andrew Stanton. The story follows a robot named WALL-E, who is designed to clean up a waste-covered Earth far in the future. And the image's of the surface are of Earth's sea bed, so are the Moon and Mars!
What a superb video! Shows how everything works from launch to exploring the surface better than anything i've ever seen. All that and it looks stunning too!
What are the rovers made out of? How do they survive 4000 F temperatures when they reach the thermosphere when things like steel would melt at 2500 F??? Why is nothing melting up there??
+79Sarwar Inside the aeroshell it only reaches about room temperature at peak heating. The reason the aeroshell doesn't burn up is because of the use of ablative materials in the heat shield. They used cork, aluminum honeycomb material, and silica--among other things in the construction of the heat shield. Ablative heat shields are intended to "ablate" or melt away gradually. As pieces melt away, they take the heat away with them, and new material is exposed and heated, and the process is repeated until the heat shield is expended. Enough ablative material is added to the shield to account for the amount which will be lost on reentry, and it protects the actual aeroshell structure behind it.
@AzizRaeesi Q1- it runs randomly Q2- it runs off solar energy look at the panels Q3-radio signals the photos take two hours to reach earth it isn't quick plus the samples it takes are examined by the rover and the collected info is sent back to nasa
Black Hole Sun... damn that's a good ol' song! Great animation, I'd sure like to have the software and the skill to use it that Maas dood has to make this stuff.
@AzizRaeesi 1. The rover has low and high gain antenna which can send a signal that is captured by the Deep Space Network, an array of large antennas and communication around the earth. There's also an orbiter around Mars which can relay the signal. Distance is not an issue. 2. It has a battery which is charged by power from solar panels. Eventually the battery will end it's life cycle. 3. The same way commands are sent to it.
Top notch digital work even at 2010 standards. So realistic that some viewers thought it fake only because they questioned who was holding the camera. Apart from that they'd assume it's for real. It blurs the line between real and unreal. Great soundtrack too. The rover foreshadows Wall-e, a lonely robot on a lonely planet.
Phoenix Probe on The North Pole of Mars has landed. I find it interesting when I do the analizis of what Phoenix stands for.... A phoenix is a mythical bird with beautiful gold and red plumage. At the end of its life-cycle the phoenix builds itself a nest of cinnamon twigs that it then ignites; both nest and bird burn fiercely and are reduced to ashes, from which a new, young phoenix arises. The new phoenix is destined to live, usually, as long as the old one. continuation.....
Awesome graphics and nice choice of song. Planets and space are so interesting...with this rapid rise in technology who know how long before we will actually catch new life out there.
@AzizRaeesi Just to add to pjwerck's comment. I don't think it sends a cctv stream as such but a series of low resolution stills from the navigation camera. From these the controllers decide the next move. The main high resolution cameras record large numbers of hi-res photographs and simple thumbnails of these are sent to earth. The controllers then select the most interesting and instruct the rover to transmit the full images. This ensures that the available data link is efficiently used.
@wilalb1 "that is now on mars?" Correct. Actually two Mars Exploration Rovers (MER): Spirit & Opportunity. 7+ Years now! Spirit is 'asleep' and in unlikely to awake as wheel failure left it unable to reach an angle to charge last winter. Opportunity continues on a long journey to a huge crater--Endeavor. You can read more on the web or even fly around Mars in Google Earth to track their adventures. A larger (car-sized) rover -the Mars Science Lab "Curiosity"- is scheduled to launch in November!
We had a school assembly with some ppl from the NASA Pheonix project (The Video is about that) The assembly had the same video. The Rover is Landing At About May 25th
Really powerful radio antennas. The rover actually conveys data to a satellite in orbit around Mars. The satellite amplifies the signal and resends back it to earth. Since there is no insulation in space, there is little trouble in transmitting the signal.
@ferdlmm A day on Mars is called a "sol" and it is 24h 37m 22.663s. That is why the rovers can do some extra work, they have this bonus of 37 minutes! :)
{when the atmospheric pressure is too low, liquid water cannot survive on surface too long, water can sometimes melt on the parts of Mars when the atmospheric pressure is unusually high, at least 680 Pa, and there are temperatures between 0-10 degress. Celsius, but this is rare, because the usual temperature is -50 Celsius and about -89 in the night}).
the scientific progress we have made to achieve this, and the amount of resources it took to get something so small to mars so we could learn; its just a clear insight into human nature... ...plus the rover is kinda cute =)
@junkers1337 I think it's a little more complicated than that. If you're traveling faster than light... how are you gonna stop in a second and how are you gonna make sure you don't crash and where are you gonna get enough fuel. There is a lot more to it than just making a faster engine. But yeah that would be an awesome first step
@1andrewman1 I heard a car would'nt start on the moon was'nt sure about mars. We could always build roads on mars. An s-10 pickup truck would only weigh 1700bls on mars
@capdasejb It is controlled by radio signals being relayed through the Mars Orbiter satellite to the Rover's computer. Next day's (actually next sol's) driving instructions are given well in advance.
@maxceedo I believe you misunderstood me when I talked about traveling into the future. Basically, your freezing time for yourself, but allowing the rest of the world to go on, so when your unfrozen your in the future. Nothing travels faster than light, so one light year to a planet, and one light year back, is just 2 years for you, but hundreds of years for those on Earth.
That was such a sweet video! It cleared up some things, I always did wonder how the legs unfolded, shame she doesn't look at her pancam callibration target in the video tho!
This is a computer simulation of two real rovers, that landed on mars just like the video shows, in 2004. They're still functional on Mars today, moving about and taking pictures and samples of stuff. The new thing that just landed is not a rover, it just sits there trying to check for water. It also use another way to land, with rockets not airbags like in the video.
It must be sad doing the same thing over and over for decades in a deserted place that has no life forms at all. Please bring back Rover when Man step foot on Mars. I just shed a tear TwT
@Bdiddly1 i love to inform you that you are wrong so i will. Mars does have an atmosphere, but as i mentioned before it has no oxygen therefore it is very, very thin being composed of nitrogen, carbon dioxide (maybe hydrogen not sure).
The Computer Graphics in this video are AWESOME! It really gives you a sense of the AstroPhysics that took place in all this Project of NASA to MARS. Absoluttly Fantastic is This Space Exploration by NASA! Thanks for posting this well put together video "smvans7"!!!
From what I've read, it's actually very close. I know the multiple stages was accurate, as well as the airbags before landing. It's very close, and amazing.
well they might not survey because the images got back to earth quicker than movements were sent back. It took something like 10mintues for the radio signal got to mars to control rover. So the only safe way of doing is to move the machine very VERY slowly
We can't send astronauts because mars is about the same size as the earth. It would be impossible for us to get off again. To account for all the weight for the crew's living quarters, and the return rocket plus fuel, the rocket that lifts off of earth would have to be 5 (probably 10) times larger then what we used for the rover. Plus, how would you go about landing a full sized rocket on mars? How would you launch it without a tower? So many things, it's not easy for nasa to send people.
Mars has an atmosphere, mostly Carbon Dioxide if I remember correctly. A parachute would not be as effective on mars due the density of the air, but it is still one of the best methods for re-entry.
@EmmeJayKay Yeah, Six long years! the rover has been rolling for that long, all because it rolls so freakin sloooow! A drawback because it depended on the Sun for it's power. But, time cannot justify the rover's durability and off-road capability when it drives that slow.
Earth and Mars have to be at the right positions in their orbit for this method to work, and the launch window only comes around once every 25 months. This method uses a relatively small amount of fuel. How long does it take to get to Mars using this method? About 214 days. (for manned flights)
@Yaaacar Mars is cold because it is farther from the Sun. Distance from the sun in million km: Mercury- 58, Venus- 108, Earth- 150, Mars- 227, Jupiter- 773, Saturn- 1418. Sunlight intensity is proportional to distance squared, so 1 m2 on Mars gets 150 * 150 / 227 * 227 = 0,44 of solar energy on Earth. That is less than half!
