Mars rover drill collects rock sample

A space-age jack of all trades, NASA's Curiosity rover recorded a first by using its drill to collect a sample from a Martian rock.

The rover sent images of the hole in sedimentary bedrock to Earth on Saturday, NASA said in a statement.

NASA said the rover will analyze the rock powder sample.

The flat rock is believed to hold evidence of wet environments that disappeared long ago, officials said.

Curiosity used a drill attached to the end of its robotic arm. It's the first time any robot has drilled such a sample on the Red Planet.

"The most advanced planetary robot ever designed now is a fully operating analytical laboratory on Mars," said John Grunsfeld, NASA associate administrator for the agency's Science Mission Directorate. "This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August, another proud day for America."

In its first two months on Mars, Curiosity stumbled upon an area where it appears that water once flowed in a vigorous stream. Scientists said the rover spotted rock outcrops that seem to have formed in the presence of water, with rounded gravels that may have been transported by water.

    Exploration and profound new discoveries meet ancient knowlegde and science. Just what the comments sattle for, an agreement or disagreement and even a challenge to previous discoveries. My take is the light that shows the dream and the dream that inspires the mind. A lot still can be discovered, and the technology we see now! its just a portion of what is yet to come, so I'd be worried about what is on my dinner plate tonight and hope that I later when I dream, I travel like a star in the galaxy and take a sight of the earth from space. That wont cost a shekel of coin nor a sacrifice to archive hence it comes to men not by chance or self-will but because of creation which led to CURIOSITY going to MARS to probe what is known but yet to be proved. Oh! and HE said to me, do not make for me anymore BOOKS, the rich will fall.

    I think it may have been an oversight that NASA drilled a hole instead of taking a core sample. (Reason: There may have been evidence that the drill "tore up" that a "core sample" would have preserved ...assuming that particular spot may have held the remains of something which may have lived there eons ago. Altogether, I am always awestruck to see the surface of an alien planet in every-increasing detail as cameras get better and better, and science does likewise. I believe that the money is well-spent and justified in its spending. After all, Curiousity is doing the work of several Astronauts. Therewith, there are no astronauts on Mars risking their lives, (freezing by night, cooking by day), etc. I ponder if the works of Nicola Tesla could be employed on Mars to simulate a magnetic field? (There is a saying that if it can be conceived, then it has already been done, or can be done). Given that Mars would need a molten core to create a magnetic field that would eventually encompass 'it' in whole ...heating the core of a planet is not beyond our technology to do, and the sun would supply all the needed energy to invoke (heat up and melt rock) a molten core, which must still exist but has cooled too much, due to planetary mass, to retain the cores required heat. Or, what could have happened (cataclysmicly), to have caused a loss (into space you say?) of liquids (water?). There is little evidence of water ever having been present. There's a lot of CO2 though, and at "ancient temperatures" it could have easily "flowed like water" (at not-so-extreme temperatures). It seems the drilling would reveal more trapped CO2 'traces' if Curiousity does indeed sit in an ancient river bed.
    And, will you Bible thumpers just shut up? Your rants have nothing in the least to do with the topic of this article. You are an irritant at best when you present yourselves in such ways. Now run along and rant about that, and beat up your wife and children, due to getting "chewed out" from half-way a world away.
    Thanks NASA! We'll be there (Mars) before we know it. In spirit if nothing else. Now, why not Venus? (It spins backwards but still has a magnetic field and temperatures just as forbidding as Mars has (leaning to the hotter end of the temperature gauge). Cheers.
    I think we will discover that whatever caused the planet, which is now the asteroid belt, to be reduced to a circle of rocks may well have wiped out Mars along with it, eons ago, and that with enough exploration we'll find it was something that makes nukes look mild. (The asteroid belt may well have been the outer-crust of Mars, blown off (sort of).

Is there unrighteousness with God? God forbid.

    So if water once flowed and there was a likelihood of life on Mars, could we help it re-populate? Or is whatever caused it to dry up now irreversible such as an unfavorable time period? In other words, could it again hold life? Pretty bad radiation from what I've heard. Is that what happen... did it lose it's ozone layer and the radiation killed everything? So how do you make an ozone layer? Fascinating stuff!

    • addison

      The reason Mars died is that she lost her molten core. Mars is smaller than earth thus the core volume to surface area ratio is much greater which means it cooled much faster. Once she lost this, then she lost her magnectic field strong enough to divert the solar winds and protect her atmosphere. And without vulcanism, and techtonics, the replenishment of the atmosphere also stopped. When the atmospheric pressure decreased evaporation increased and eventually all surface water disappeared and was lost to space. We could artifically recover the atmosphere and also using ice asteroids replenish the water, but without creating a strong magnetic field it would be a constant battle to protect living things against the radiation and atmspheric loss.

      Patience... This is a two Earth year (1 Martian year) mission, and could very well go far beyond that if all the MSL's systems remain a-okay. Curiosity is a *very* expensive piece of hardware they cannot repair it if a part breaks. Consequently, the engineers and scientists are extremely cautious and methodical when operating it.

      Also keep in mind that the scientific teams behind each experiment on Curiosity want as much time as possible to use their particular 'baby', so time has to be parceled out carefully.

    • ATS

      Haha, nice! But, if I remember correctly, it takes roughly 15 minutes for the Rover's transmissions to reach Earth which means the scientists here at home aren't getting the images "real-time". They basically have to create a map with the delayed images and navigate from there. Hurrying along would not bode will for the Rover or the mission.

        Also, no mention of bacteria and viruses, which, one would think, would be quite an important message for humanity. No mention of marsupials, or penguins, and no mention of.... well anything that people in the middle east, at the time, would not have known about. One could almost conclude that perhaps, just perhaps, the book is a product of less than divine sources.

      A koala bear, if it were to basically run all day, can travel maybe ~20 miles. It only eats eucalyptus leaves. Eucalyptus leaves on grow in Australia. Even if there were a land bridge for it to have crossed, it would have needed to travel 8000 miles to get to the Ark and then it would have needed to travel 8000 miles back. which would have taken 800 days plus 30 days (and nights) away from its food source. Now I believe in God and I believe that created by a superior being is as logically tenable of a position on the origin of the universe as any other, but there is no way the creation account in The Bible is literal, and the sooner we believers get over that the better we are going to be able to effectively serve the rest of humanity.

      Noah went to Antarctica via a huge fish. Then brought back the penguins in the belly of the fish and the fish spit them off onto the shore. Noah had to wash the penguins off all the while the little buggers were pecking at him. Noah lost his index finger over the whole thing. He also had what we call PTSD from riding in the fishes belly with the penguins pecking at him the whole time.

      • JPO

        You don't have a clue about basic scientific principles or about the details of the Martian atmosphere. Gravity is what makes stuff come down. Air resistance can slow a moving object, e.g. your golf ball. Unless the ball is hit fast enough to escape the gravitational pull of the Moon or Mars as the case may be it will come down. How fast it goes initially depends on its mass and how much energy it is given by its impact with the golf club. Scientific illiteracy prevails in America today.

    Geez, can't we just enjoy robots on Mars for five seconds? Why is that not amazing? Can you drill a hole on Mars? Me neither. But I love that we get to see it. Smile people. It's not that bad down here.

      We were drilling for heavy metals on Mercury when, as a child I watched a golfball hit on the Moon on TV. Did it ever land without air to slow it down?

        Yes, it's called gravity moron. Gravity is what makes you ball come to the ground not atmospheric drag. Get an education.

        This is what happens when your politically-selected (elected?) school district chooses to teach creationism over science – you don't have a clue about how the physical world actually works. Using your understanding, you could be put in a vacuum chamber here on Earth, get you to hit a golf ball, and it would never come back down. But of course, you never got any education in the sciences, so how could you know better?

        It's one thing if you believe in conspiracy theories (like the Moon landing being a hoax), but at least think through the stupid statements you continue to make. Use a search engine on your computer and learn about gravity, air resistance, mass and weight, velocity, momentum.

    Obviously, God created Mars to be a pleasant red dot in the sky for humans. He would have no reason to put water there, so there has never been any water on Mars. Uranus, Neptune, and Pluto don't exist because they're not mentioned in the Bible.

      The Bible is merely a selective collection of old writings. Try the faith given to mankind without studying or listening to BS revelations by BSers. Pagan...the true faith of the HUMAN. You will be enlightened and enjoy a much more relaxed life.

    If they hit oil Exxon Mobile will have a rig up and running in ten years. The pipeline however will take a bit longer.

      You're right, I didn't think of that, NASA is destroying some of the last pristine wilderness on Mars. We should have a ban on the use of skycranes to land any kind of payload on Mars. That would effectively prevent any future attempts at Mars exploration while appearing to be just a commonsense precaution.

    Wow! This is just so worth it. Unfortunately we are better at exploring dead planets than we are at keeping this fabulous planet alive.
