And so as Asian Americans, maybe we gravitate more towards Asian Americans because we get the traditions that they're observing or the food that they're eating. Rover with her friends, going to the mall.
That would be a coup if we can get that in a couple of years. Rover navigation-- this is just showing one of the Atacama from this past season. I believe it might have been the same run you saw it trundling uphill.
finances are not a question uh so if you so if you're the government then uh they'll put those on satellites and Mars rovers and stuff like that and that's where they they can get um 30 to 40% efficiency on on the panel uh which but they'll be paying you know 100 times more than what the consumers are uh but
So astatine, in its most stable form, has a half-life of eight hours, which means that all of the energy emitted by the plutonium powering the Curiosity Rover over the course of the next century, if it keeps running, is being limited by our lump of astatine in an afternoon. This is why no one has ever collected enough of a sample of astatine to really look at it, because any sample large enough to see with a naked eye
yeah there it is that's a tempo Rover then tell him that his on night are over s I'm so
It wasn't just Sean Parker and the radicals and the Metallica folks upset about that. Because Rove is trying to make a case that we're going to pick and choose winners in these states, so that they're
So I have another slide here that gives you just a very simple breakdown of what that looks like. Each Rover is working when it's-- starts a work day at the same time. But the scientists have to change their work day 40 minutes every day forward.
In that process, did you come out with a favorite? The Rover receives its commands at 10:00 AM every morning, Mars time.
You execute the orange stuff. The rovers, even though one is much larger than the other, they're both rolling along at 10 meters per day on average.
Usually we don't fight each other too much. The rover itself will carry four instruments, maybe a fifth, maybe three. We will see this.
Mars in August of 2012 uh it's a one tonon nuclear powered uh Rover still cranking does great work very slow from August 2012 to just a few days ago it has driven n nine miles
fiscal 15 the year mark would be in uh end of September and This Is Us driving around the Rover at um NASA Johnson in Houston and uh it gives you real sense of scale there um some of the steering possibilities you see the solar aray in
So make you guys hungry. Our Rovers are there.
We flew it twice on Endeavour, and it was just a lot of fun. Lunar Rover to explore for volatiles at the poles.
consumer oriented America so there there he is here's another person I think you all remember with one of his top trusted aides Karl Rove supposedly trained with him but so here's your other toys now you all know him he has a place around here so hope you're taking notes of which governor signed the first wide stage and
But all of the prior rovers-- for example, if just focus on Mars, all of the previous missions, the goal was first to see, can we send a rover to Mars? Check. Did water used to exist on Mars?
And that technology was not-- it existed at the time of Curiosity, but it wasn't made so that it could be small enough in a nice compact form factor and placed onto the rover. It's really interesting. A lot of the things that fly have been in existence for quite a while.
The Perseverance Rover, I think, all of you've just been tracking and heard about, and I showed you in the third slide is this rover,
So landing rovers on Mars has been actually very challenging.
It's a rendering of one of the robots by Dan Maas, who made a very nice animation of the journey that the Rover took from launch to landing and then roving across Mars. The right image is one actually taken by Opportunity Rover, which was the second of the two rovers, and this is an example--
The slides don't continue, so I'll just continue with the description. There were two rovers. Each of them were set to work when sunlight was shining in their location.
Each of them were set to work when sunlight was shining in their location. So with two rovers on opposite sides, in a days period, always one would be working. The science team at Jet Propulsion Laboratory was self-divided into two groups, each one dedicated to one of the rovers.
your work day ends, but you could climb a staircase and be on the other side of Mars and suddenly working with scientists who are working with the other Rover, who they've now shown up for their shift. And in this enclosed space, it very quickly-- you lose track of time.
Yes. So it seems, then, NASA made this choice at some point that we're going to run this mission based on the time that the rovers are seeing, which is Mars time, as opposed to the time that the actual scientists are seeing, which is Earth Pasadena time. What went into that decision?
And though you will have human physical energy after the sun is down, you don't have that resource to help you see, just to put it simply. With the rovers being solar powered, it wasn't technically necessary that they only work during the day when the sun is up, but it would increase the chance of their longevity.
Curiosity-- the Mars Rover.
Because our rovers on Mars-- so let me tell you how fast Curiosity runs.
I got the Range Rover.
It landed a little rover called Sojourner that was about the size of a baby.
the wheels of the rover.
We've had rovers rolling around at least one of them.
It's not just that the Rover is a machine. It's that the Rover carries with it a lot of human hopes and ambitions. And I think you kind of communicate that, as well, what we're were hoping and dreaming to explore on the surface of Mars.
In that process, did you come out with a favorite? that the Rover has, so it can take the broadest views.
In that process, did you come out with a favorite? And so the Rover executes its one sol's worth of commands.
They have a rover, but they don't have a plane.
Folks we have a Rover on Mars, right now, looking for life.
And now we have rovers.
The MSL Curiosity Rover is studying these sediments, which were deposited in that lake environment, searching for possible chemical signatures of habitability,
All of our orbiters also do secondary jobs that include relaying communications from the rover. So if the rover had to talk directly back to Earth, that's a very challenging communication link. It's a lot easier for the rover to squirt information up to an orbiter, which then can transmit the information back to Earth, something that we call comm relay-- communication
And that actually contains two major elements. One is another rover to go out, and pick up those samples, and return them to the MAV, the Mars Ascent Vehicle, which is the rocket that flies on that mission. So that mission carries a fetch rover and carries the MAV rocket.
You execute the orange stuff. The first rover could touch down on the Martian surface and collect samples by drilling into rocks and then stashing the samples in sealed tubes.
You execute the orange stuff. This follow-on rover would go fetch the samples, load them into a container, and bring it back to a lander
However, if you're looking for life, this complicates things. The current Curiosity rover is not sterilized to the levels that would be necessary to send it into what we call a coast special region. A special region is a place where maybe, just maybe, life could exist under some conditions
So this is it sitting in the Atacama as it was after nightmares of getting it through Chilean customs. Included in this rover, we have three different robotic subsystems. There's the K-REX2 rover and its own autonomous navigation.
since you're looking uphill, it's not quite as obvious. But the rover is going and finding its own way around the boulders and obstacles in its path. We have the arm that, again, from MDA Aerospace-- we're not usually always scratching
I believe it might have been the same run you saw it trundling uphill. Just the rover both does image processing for navigation. It has a lidar mounted on it as well.
So we found some nice ways in which we can fault or break the drill while it's on the rover so we can then look at how does being on a suspension or minute movements in the rover platform affect compared to a lander platform or something that's more stable. So those were all very useful for us.
chances to get off now this is the resource prospector uh surface segment we call it that means it's the Rover and the payload system together because it can move in all directions it can crab walk we immediately get on the sun to be power positive and then we can move in any direction of course at that point one of the big benefits of having the uh
illustrate uh some of the work that we've done so what you're seeing here is the krex Rover at Nasa am Research Center out in the Rover scape and we've got the neutron spectrometer right up here in the front that's the one that you saw in the video and then a Gamay Source out in the front on this piscus that sits out front
Banks um now revolving a little bit further very pretty uh suspension drive system we built five of these four of them for the Rover and then one for testing uh including the driver boards um uh these are the 1G Wheels uh which would look a little different and we've already evolved them since this point
