133mhz processor in the rover

4GB storage, the onion was half there :p

Transistors has to be "hardened" against radiation so that they don't switch everytime a particle hits it. Those processors and memory have to be developed differently than consumers electronics, for example they can't use smaller processes such as 22nm. Finally as the other post over me stated, power and temperature requirement also effects it.

Actually I think it's a matter of protection from radiation, movement, etc. The electronics aren't so small and therefore less likely to suffer damage from radiation.

It's this. Also, these processors are time-proven for reliability and the lower complexity makes their behavior more predictable.

Also, what they have there is what's required. No one's playing Crysis 3 on Curiosity's computer.

It'll probably last a couple of decades, always on, on another planet.

When they say your IPhone wouldn't survive the trip, the radiation and temp changes must be significant. Plus they hit 11G on entry. It's a couple of heavy duty computers you're not going to get at Best Buy.
 
3.88 fps looking down from the skycrane dropping, thrusting to a save level then preparing the rover, its only like 10 seconds worth but it was cool to see.

They published that a couple of days ago - here you go.

I'm confused. Diablohead is mentioning Skycrane footage, which is why I got excited. Wasn't Skycrane the hovering craft, that lowered the rover to the ground?

The footage in that link is just from the bottom of the rover. Not from the Skycrane.

Power is also a factor. The nuclear generator only produces about 500 watts and in 10 years it will only be about 70% of that.

It was the same video, the rocket platform didn't have a camera.

My mistake if it's a cam on the bottom of the rover, it just looks like it's from the skycrane.
 
I missed the conference, but it looks like they named the landing site Yellowknife.
Yellowknife is the name of 51st Quadrangle of the Landing Ellipse, not the landing site (according to MSL team). Via the telephone, a reporter asked a series of questions about the choice and specific usage of this name. Her questions couldn't be answered directly by the panel, eventually someone from the audience responded; and then later, the head of [the landing site team?] explained the Earth-Mars connection.

Yellowknife has some of the oldest geology in N America. To get there, one can fly, drive, or take a boat; then, one gets into a bush-plane and flies into the wilderness for a month(s) long geological survey of the rocks. This was hinted as paralleling the endeavor on Mars, bridging geological activities on Mars. Gale Crater has some very old rocks that are exposed to help determine if the planet was likely more hospitable to life than today.

And the lady was all like "well did somebody talk to the representatives of Yellowknife about it or you guys just decided to do it!?" implying that HEY IT'S NAMED AFTER US WE MUST HAVE A SAYING IN IT.

You know, stupid people.

Will they be releasing pictures/videos or having any news conferences over the weekend? Or will all new info dry up until Monday?

Dry-up for 4 days or so. Next news conference on Monday? If so, they will be reviewing the prelinary data, showcasing the teams, reiterating explanations, and explaining software update.

I see, that's why I was wondering if there was a way to cheat and get around the signal delay using something besides radio signals. I thought it was remote controlled at points. I see that any of the 10 fps 720p that comes out, even live is still delayed.

You can get it down from 13 minutes, but 3 minutes is the limit when earth and mars are closest together.

I was just poking around on the MSL JPL website and it doesn't show any press conferences scheduled after today...I have enjoyed the conferences and hope they don't completely stop
 
Space Law, one of the newest branches of the Law. The UN has documents on various space treaties and committees that are set-up to monitor and discuss space-exploration/exploitation. It is much like International Law, it is only as good as participants allow it to be.

Looking at International Business Law, it is clear that these regulations can strengthen confidence and ensure exchange. The best places, in the US, for Space Law are (arguably) George Washington University, Georgetown, and American University. Search around those places for published information and upcoming events. Being in DC they get some of the best speakers and lecturers. Tuition will cost you a couple hundred thousand dollars, so it is not a poor man's pursuit. It should be reiterated that the business-side of enacting policies will ikely be the most influential.
.
Nah, I'm already paying for one JD aleady! Yeah, I have seen some of the general things and the UNs Outer Space Law area and it is pretty neat, never knew the US filed a notice because Curoisty has "nuclear material" (it's next to nothing, but it's a report that gets filed). I guess what I mean is the nitty gritty things to emerge after colonization or even a base. Is someone born there a natural born US citizen, is it considered federal land, how is it governed, things like that. I mean what is the law if a Russian had gone nuts on Mir and stabbed a US or say third country Astrounat, things like that. I know it's speculative to the extreme, but I get a really dorky high at the thought of these issues. Still I like some of the resources from check that source. I wish I still had JSTOR access and could read old issues of the Space Law Journal.

That's pretty impressive,

Not with the speed of light being a brick wall. You'd need to find a way to fold space-time to cheat.
Eh, I don't want the demon raping sado creatures just for trying to shave off some time.

Good point to be made. I will argue that it is not a "major reworking of physics" that would be required but rather a more complete understanding of the Universe. Does this mean Unified Field Theory, a new branch of particle physics, or a tweaking of current formula? I have no idea. In the watered-down sense, quantum physics didn't completely invalidate Newtonian Physics, it just helped define the parameters of the application. So,I do agree there is a giant unknown gorilla in the room, but I don't think it will effect the nature of Physics Laws currently proven, beyond establishing limitations. Who knows? A Unified Field Theory very well could change Physics, but at that point one might ask if it is a stand-alone brand-spanking-new science or one that fills in the gaps.

I think the Unified Field Theory makes the most sense.

When you consider the expansion of objects within space, as well as space itself, and how light, distance, and time are all interconnected, it really is like a field with different parameters being different manifestations of the field. The shape of space changes due to gravity. The distance between objects also impacts the strength of their gravitational effects, as do their masses, as do their energies, and so on. As space has expanded, so too have the concepts of time, distance, speed, spin, charge, etc.
 
No problem, information dissemination is the name of the game. Knowledge will die if it is not shared. ...anyway, regarding the JSTOR access: check with nearby Depository Libraries. Some will have the subscription, with limited access, and others will not. If you don't know of any disgruntled faculty that you could butter-up and get access, there might be communitiy colleges with criminal justice classes that would grant access but that is money spent. Search around, maybe a former classmate is part of a firm that doesn't mind semi-open-access, in the spirit of academic pursuits. Space Law, fuck yeah!
or is it: fuck no?

It all boggles my mind, and is so beautifully; elegant, brutal, and complex.

Scientist Discovers Plate Tectonics On Mars

I had just posted that on the previous page lol.

Also: Anyone notice that there seem to be very, very few uses of the number e in nature (by which I mean in physics, chemistry, astronomy, astrophysics), even though it pops up everywhere change and quantity relate to each other proportionally?

My conjecture is that a lot of the holes in our understanding of the universe will involve e... Like we're looking at at a partial differential equation and we're completely blind to one part of the equation, as we've fixed it as a constant (that being specifically how the past and present and future affect each other, because we're limited to looking and moving in only one direction).

I mean, Pi/tau pop up all over the place, but when you think about it, e would be pretty hard to see without a clear vision of past, present, and future all at once, unless you make a blind guess based on a conjecture/hunch and turn out to be right.

Hell, maybe e and pi fought it out and e lost. Could explain why there seems to be a hidden or rare (but under our current understanding, should be as common) flipside to what is "normal" in our universe (ie: antiparticles. Also the elusive dark matter and dark energy, etc). It's like there's half a universe that we know is there, but can't see, because we're not omnipotent and omnipresent. Also could explain why we see pi show up so much but not e. Our perspective limits us to directly observing pi-biased information, or e "disappeared" from nature along with the anti-particles.

I'm kind of just rambling nonsense conjecture, though I do have a decent base of understanding of chemistry, physics, math, and astronomy at the collegiate level, but nothing at the doctoral or post doctoral level. IE: I did take organic chemisty, I did progress beyond basic calc into linear algebra and diff eqs, and I was exposed to group theory through cryptography, and I did learn physics beyond your basic newtonian laws, going into the work of Gauss and Maxwell and a bit beyond them...

what's this yellowknife stuff you're talking about?

As mentioned, they named part of the landing ellipse Yellowknife. However, the reason we were mentioning it in the thread was because some woman from Canadian News called in asking about the name during the Q/A session clearly trying to get a cute soundbyte for her news program about how awesome a name Yellowknife was. She did some really annoying stuff.

First, she was stupidly asking the wrong people. This was a panel for the EDL team, not the science team who coined the name. Never the less, she kept asking trying to get an answer. The JPL rep at the podium tried to find a science team member in the back of the room. She got up and answered some but then the woman from Canada just kept asking questions. "Was it because we have ancient rocks here in Yellowknife?" Stupid fluff questions like that.

Furthermore, when hosting this kind of event you're only supposed to ask one, maybe two questions at a time but this news woman just kept going like it was an interview making all the other reporters wait. Finally, the JPL rep at the podium cut her off and told her she can call the PR office for more information about the name.

At the end of the conference, the head scientist at the back of the room answered the question again as a good gesture. Still, that woman news reporter was annoying and holding up the conference and taking away from the landing team's moment to shine by totally going off topic. It was frustrating to watch.

I think even though Einstein found quantum physics preposterous, he probably had the same underlying intuition as I do about the universe when he became so obsessed with a grand unifying theory and came up with the idea of a "Universal Constant." probably looked at it a lot like quantum physicists now view string theory ("Wait, now you're breaking this shit down even further? No, now you're just splitting things up and fumbling around with the numbers to a point where they make no sense and can say anything you want them to, let's try to put together the pieces we already have").

It's just that we can't tell if our jigsaw puzzle is a clock or a door until we find some of the pieces that we've misplaced.

You know I think my law school allows alumi the ability to use the library for research. Hmm that means going back to Newark...I'll keep searching for options.

Sorry! I did search the thread for tectonics, but my fingers must must have gone awry and I didn't find your post. :/

Its ok, I didn't elaborate much and more people saw your post, which means more people were informed :)

Sorry if old, but...they are downloading new software to you know, drive the thing lol

http://www.nasa.gov/mission_pages/msl/news/msl20120810.html

PASADENA, Calif. -- NASA's Mars rover Curiosity will spend its first weekend on Mars transitioning to software better suited for tasks ahead, such as driving and using its strong robotic arm.

The rover's "brain transplant," which will occur during a series of steps Aug. 10 through Aug. 13, will install a new version of software on both of the rover's redundant main computers. This software for Mars surface operations was uploaded to the rover's memory during the Mars Science Laboratory spacecraft's flight from Earth.

"We designed the mission from the start to be able to upgrade the software as needed for different phases of the mission," said Ben Cichy of NASA's Jet Propulsion Laboratory in Pasadena, Calif., chief software engineer for the Mars Science Laboratory mission. "The flight software version Curiosity currently is using was really focused on landing the vehicle. It includes many capabilities we just don't need any more. It gives us basic capabilities for operating the rover on the surface, but we have planned all along to switch over after landing to a version of flight software that is really optimized for surface operations."

A key capability in the new version is image processing to check for obstacles. This allows for longer drives by giving the rover more autonomy to identify and avoid potential hazards and drive along a safe path the rover identifies for itself. Other new capabilities facilitate use of the tools at the end of the rover's robotic arm.

Magnetosphere, imo. That radiation is a bitch.

magnetosphere would likely come from increased mass (heats core, creates convection).

also, there are other ways we could get around that with engineering.

but there's no way around a lack of mass

NASA has started a rather ambitious project: to provide open-source everything. The main site is located at http://open.nasa.gov. From here, there is access to data, code and applications, among other things. This is a great launching point for anyone interested in space science and NASA work. In this article, I look at what kind of code is being made available that you might want to explore.

...

When you're ready to go and launch your own satellite, you can download and use the Core Flight Executive (cFE). This software is used as the basis for flight data systems and instrumentation. It is written in C and based on OSAL (Operating System Abstraction Layer). It has an executive, along with time and event services. You can track your satellite with the ODTBX (Orbit Determination Toolbox). The ODTBX package handles orbit determination analysis and early mission analysis. It's available as both MATLAB code and Java.

...

The open-source project at NASA doesn't cover only code. NASA has been releasing data as well. The Kepler Project is looking for exo-planets. As I mentioned previously, you can download data from the Solar Dynamics Observatory. You can work on climate data by checking out information from the Tropical Rainfall Measuring Mission. You can look up tons of data from the various moon missions, from Apollo on up. There also is data from the various planetary missions. Climate data and measurements of Earth are available too.
