Steven Squyres: The Mars Exploration Rover Mission

[ForexReviewsCentral]

This is the truth....

lies



[0lafsky]

It is amazing project, and the unexpected lifecycle of the rovers gives huge credit to all the scientists and engineers working on this project, the whole team and humanity. Brilliant.

It feels like an age of exploration is just around the corner, my spirit rising at this thought.

Humanity sits on the perch almost ready to fly, to see, to touch, to experience and understand explore all those things and places around us, but we are stuck in old fears, unfinished quarrels and ROI calculations.

[0lafsky]

Great Stuff, 1 thing:

There are evidences backed by empirical tests in laboratories that prove stratification in sedimentary rock formations in flowing water environments occurs simultaneously, thus each observed strata in the formation can not be used separately to define the age of the formation as sum of estimated times it takes for individual strata to form as solid rock layer. Then in B/W scenario time is measured in length of formation and not height of and numbers of layers.

fascinating.

[audreyfischer]

Clearly evident is the dedicated, focused passion of a skilled remarkable team.

[flowewritharoma]

awesome lecture! thank you for uploading this video! I have liked it!

[KarbineKyle]

Great Lecture! Thanks A LOT for the upload! I really enjoyed it! I LOVE ASTRONOMY! I ALWAYS HAVE! Mars is a very beautiful and mysterious planet, and I hope we set foot on the Red Planet soon! =)

[TheSpaceShit]

call it good

[jmyjms86]

like i said eventually earth will be mars. we are traveling away from the sun like every other planet. and yes venus will be optimal for life.

[toob247]

@jmyjms86 we get closer to the sun every year do to gravity , the universe is expanding not the solar system.

[bondurango]

NASA now admits there's water under the ice caps on Mars. But since the ice caps contract, they can't explain how water melts at temperatures that never go below freezing. John McCain calls NASA an acronym for "Never A Straight Answer". Guys like Squyres (a geologist, not an engineer) are hired & promoted because they don't question the integrity of the equipment used on these projects. He's the kind of academic idiot NASA manipulates as part of their 60 yr. old, dog & pony show.

[jmyjms86]

OF COURSE THERE USE TO BE WATER AND LIFE ON EARTH!! PLANETS ARE SLOWLY MOVING AWAY FROM THE SUN AND EVERY PLANET IN EVERY GALAXY IS SLOWLY MOVING AWAY FROM THEIR SUN. AT ONE POINT EARTH WAS TOO CLOSE TO THE SUN, AND AT ONE POINT MARS WAS AT THE PERFECT DISTANCE FROM THE SUN TO MAINTAIN LIFE. MILLIONS, BILLIONS OF YEARS AGO? YES. BUT ONCE. BILLION YEARS, MILLION YEARS FROM NOW...WE WILL BE MARS..

[iborrada]

@jmyjms86 then we''ll fuck off to Venus, by then it should be quite nice! :-)

[jmyjms86]

@iborrada I believe we're not far away from the discovery to travel the speed of light. we already invented the vesmir this year. capable of travel ten times the now fastest speed. it all has to do with making a craft vibrate at such high frequency that it becomes energy matter instead of mass. meaning we will be making mass weightless..and able to travel at higher speeds without the pushing back effect of inertia

[davidchenard]

No water?  Freezing temperatures? What about those rover tracks? You can't compact dry or frozen soil. That ground clearly contains moisture in liquid form. What a load of crap.

[cavac]

@davidchenard Of course you can compact dry soil if it is in the form of sand.

This isn't beach sand that has been eroded by water and contains tiny round pebbles. The kind of sand on mars and the moon is primarily eroded from rocks by wind and is make out of quite sharp fragments that kling to each other (so it's more like volcanic ash).

Under pressure this particles break loose from each other and settle in a tighter pattern (e.g. they are compacting).

[davidchenard]

@cavac No you can't. Neither soil nor sand can be compacted when dry or frozen. That is a simple fact. Ask any farmer or gardener or construction worker.

Your second claim is wrong too according to NASA. The sand is believed to move slowly in Martian winds due to little atmosphere. Ice, gravity and water in the past provided the erosion of rock into sand.

And that nonsense about the sharp fragmented sand forming from wind erosion is laughable. You made it up. Where do you get your info?

[NGYT40]

Amazing!!!!

[soypirata1]

Hey is this real

[Thetonytheman]

wtf, this is 1 hour 7 minutes and 6 seconds??????

[POPPETT1000]

Steve is great. I love that fact that we are still searching for life. Smart man.

[zapfanzapfan]

Sorry, five years ago, the video was uploaded three years ago. Designed for 90 days and lasting more than 6 years... Fantastic :-)

[zapfanzapfan]

Fantastic project and a very good presentation. This was three years ago and the rovers are still working although one is stationary, and Steve´s wife is by now quite tired of them and wondering how much longer they will last...

[wilmers16]

Millions of people here on EARTH are starving to death and try hard to get on with their lives yet spending millions of dollars and going millions of miles just to find LIFE...where the true meaning of LIFE is here on EARTH.

[seaninboise]

@wilmers16 just because there will always be a poor class, doesnt mean we should limit our research of the cosmos... if we operated like that we would never make any progress because there will always be that bottom percentile of humanity

[DansFishChannel]

@wilmers16 thats the whole point. Once they find a place that can support life they can send all those starving people over their with a bunch of crops, seeds, and tools. Nasa is no fool.

[DansFishChannel]

@wilmers16 just kiddin but your comment is rediculous. The current sysytem is responsible for all that suffering. Spending more money is not the answer its fixing the system that the current money is distributed. And finding the origins of life is extremly important and its not necesarrily exposing itself on earth.

[NWM11Bravo]

why is it that the scientists at nasa are the only ones who seem clueless about the reality of ET craft and their visitation? i think being a left brain oriented skeptical robot is a must to get into the space program. even when a being appears right behind a space walker he is clueless.

[sbergman27]

Nice that they used the very reliable Delta II's I'd hate to have seen these wonderful probes delivered straight to the bottom of the ocean like the Orbital Sciences "Taurus" usually seems to do.

[polarspirit]

9:16. Big sized dick.

[Clarknipolo]

stupid....video and nasa stupid , conquisted Mars europe russia u.r.r.s and e.s.a ente space aereonautics italy conquisted from Mars.....

[sirjulez2004]

i wonder what compression he used for this video. an hour long and good quality.

[sys738]

excellent presentation!i took his class last semester and it was awesome.

[conjcsisepuede]

nice and amazing!

[jcstevens91]

o i see i see

[smartyjones2004]

Excellent presentation by Dr. Squyres. It was very intriguing throughout the entire presentation. Thanks for posting the video CalTech.

[davidchenard]

What about the unfrozen water in the surface soil? Any farmer or gardener can tell you soil compaction requires moisture. Since dry soil can not be compacted, the rover tracks clearly indicate there is moisture in the soil. This is not dry soil, and it is not permafrost. This is a clear indication of water. How can the temperature be below zero while the dark distintly compressed Rover tracks could only result from a high soil moisture content?

[davidchenard]

Why name hills on Mars after the Columbia space shuttle? Has anything else been named after other space shuttles?

[sbergman27]

@davidchenard: Perhaps you missed it, but less than a year previous to the discovery of the hills, we lost Shuttle Columbia upon reentry and 7 astronauts died.

With that in mind, I hardly see that the naming of the hills required any further justification.

[Starter61]

Excellent presentation, thank you very much !

[suhas1717]

great, isn't it??

[you2tube22]

Forza MER!
