September 10, 2012 Curiosity Rover 'Sniffs' Martian Air for Signs of Methane --Will It Prove to Have a Biological Source?

 

           Original

 

"The loss of Mars' atmosphere has been an ongoing mystery," Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington, said.One theory is that Mars lost its magnetic field, without which it was defenseless against the brutal onslaught of solar radiation which stripped anything not nailed down (like air) off the planet. Now, Nasa's Curiosity rover has measured the Red Planet's atmospheric composition by sucking the air into its big "Sample Analysis at Mars" (Sam) instrument to reveal the concentration of different gases.The Sam analysis is ongoing but NASA says carbon dioxide will dominate as it has in the past by the Viking probes in the 1970s and the Phoenix lander in 2008.

Of paramount interest will be whether a signal for methane, which has recently been observed by satellite and by Earth telescopes, has been detected by Curiosity.Methane has a short-life span and its persistence suggests a replenishing source of some kind - either biological or geochemical. It is hoped SAM can shed light on the issue.

The results from this first test could be announced next week, said Curiosity deputy principal scientist Joy Crisp, but she cautioned that it would be some time before definitive statements could be made about the status of methane on Mars.

"When Sam is at its best it can measure various parts per trillion of methane, and the expected amounts based on measurements taken from orbit around Mars and from Earth telescopes should be in the 10 to a few 10s of parts per billion," she told reporters."But it's so early in the use of Sam, which is a complicated instrument, and we have to sort through the data."

Planetary scientists have long been puzzling over what could be producing methane gas detected in Mars thin atmosphere. Methane molecules are easily blown apart by ultraviolet light from the Sun, so any methane around must have been released recently. The presence of methane has triggered a hot debate in the Mars science community: is it a sign of microbial life or geology? Perhaps the Curiosity Mission will give us the answer.

September 07, 2012 Image of the Day: Tracks of Human Technology on Mars --Curiosity Begins Its Journey!

"No cities. No seas. No forests and no battlegrounds. No prairies. No nations. No histories and no legends. No memories. Just features, features and names. Argyre and Hellas and Isidis. Olympus and Alba and Pavonis. Schiaparelli and Antoniadi, Kasei and Nirgal. Beautiful double-rimmed Lowell. Names from one world projected onto maps of another."

Mars is a microcosm -a spiritual jumping off place in our exploration of the Universe. The white spaces -the unmapped, unexplored, unknown white spaces of the map of Planet Earth are no more. Our 21st Century explorers look to our Solar System and beyond for the challenge of the unexplored, the unknown.

Mars, Oliver Morton tells us in "Mapping Mars: Science, Imagination, and the Birth of a World,"  "is continuous, seamless and sealess. Its great mountains stand alone; there are no sweeping ranges, no Rockies or Alps or Andes. The rivers are long gone. There are no continents and there are no oceans, and thus there are no shores. Given patience,, provisions, and a pressure suit you could walk from any point on the planet to any other. No edges guide the eye or frame the scene. Nowhere says: Start Here."

Unitl now, tracks from the first drives of NASA's Curiosity rover are visible in the image aboive captured by the High-Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The rover is seen where the tracks end. The image's color has been enhanced to show the surface details better.

The two marks seen near the site where the rover landed formed when reddish surface dust was blown away by the rover's descent stage, revealing darker basaltic sands underneath. Similarly, the tracks appear darker where the rover's wheels disturbed the top layer of dust. *Observing the tracks over time will provide information on how the surface changes as dust is deposited and eroded.

August 28, 2012 First Recorded Human Voice from Earth to Another Planet and Back --NASA Mars' Curiosity Mission

 

                      Curiosity-NASA

In historic spoken words radioed to the rover on Mars and back to NASA's Deep Space Network (DSN) on Earth, NASA Administrator Charles Bolden noted the difficulty of landing a rover on Mars, congratulated NASA employees and the agency's commercial and government partners on the successful landing of Curiosity earlier this month, and said curiosity is what drives humans to explore. 

"With this voice, another small step is taken in extending human presence beyond Earth, and the experience of exploring remote worlds is brought a little closer to us all," said Dave Lavery, NASA Curiosity program executive. "As Curiosity continues its mission, we hope these words will be an inspiration to someone alive today who will become the first to stand upon the surface of Mars. And like the great Neil Armstrong, they will speak aloud of that next giant leap in human exploration."

"The knowledge we hope to gain from our observation and analysis of Gale Crater will tell us much about the possibility of life on Mars as well as the past and future possibilities for our own planet. Curiosity will bring benefits to Earth and inspire a new generation of scientists and explorers, as it prepares the way for a human mission in the not too distant future," Bolden said in the recorded message.

The telephoto images beamed back to Earth show a scene of eroded knobs and gulches on a mountainside, with geological layering clearly exposed. The new views were taken by the 100-millimeter telephoto lens and the 34-milllimeter wide angle lens of the Mast Camera (Mastcam) instrument. Mastcam has photographed the lower slope of the nearby mountain called Mount Sharp.

"This is an area on Mount Sharp where Curiosity will go," said Mastcam principal investigator Michael Malin, of Malin Space Science Systems in San Diego. "Those layers are our ultimate objective. The dark dune field is between us and those layers. In front of the dark sand you see redder sand, with a different composition suggested by its different color. The rocks in the foreground show diversity -- some rounded, some angular, with different histories. This is a very rich geological site to look at and eventually to drive through."

A drive early Monday placed Curiosity directly over a patch where one of the spacecraft's landing engines scoured away a few inches of gravelly soil and exposed underlying rock. Researchers plan to use a neutron-shooting instrument on the rover to check for water molecules bound into minerals at this partially excavated target. *During the news conference, the rover team reported the results of a test on Curiosity's Sample Analysis at Mars (SAM) instrument, which can measure the composition of samples of atmosphere, powdered rock or soil. The amount of air from Earth's atmosphere remaining in the instrument after Curiosity's launch was more than expected, so a difference in pressure on either side of tiny pumps led SAM operators to stop pumping out the remaining Earth air as a precaution. The pumps subsequently worked, and a chemical analysis was completed on a sample of Earth air.

"As a test of the instrument, the results are beautiful confirmation of the sensitivities for identifying the gases present," said SAM principal investigator Paul Mahaffy of NASA's Goddard Space Flight Center in Greenbelt, Md. "We're happy with this test and we're looking forward to the next run in a few days when we can get Mars data."

Curiosity already is returning more data from the Martian surface than have all of NASA's earlier rovers combined.

"We have an international network of telecommunications relay orbiters bringing data back from Curiosity," said JPL's Chad Edwards, chief telecommunications engineer for NASA's Mars Exploration Program. "Curiosity is boosting its data return by using a new capability for adjusting its transmission rate."

Curiosity is 3 weeks into a two-year prime mission on Mars. It will use 10 science instruments to assess whether the selected study area ever has offered environmental conditions favorable for microbial life.

Wouldn't it be better to play this sound on mars itself with loudspeakers, record it with a microphone and send it back to earth, so we could listen the way it sounded on mars? It would also be the first human words uttered on a different planet.

I like that idea. Hope NASA gets it.

I have a better idea. How about we stop all the cheap publicity stunts and get on with expanding our presence in the solar system and knowledge of the universe?

Why is Mars part of the "Deep Space Network"?

Posted by:Robert |August 29, 2012 at 05:54 AM

"small step" and "giant leap". Sound familiar? zzzzzzzzzzzz...

Posted by:Robert |August 29, 2012 at 05:56 AM

Nick
The acoustics would be studied just like any picture for any kinds of anomalys and I am sure would raise new questions and answer some old ones. Or not but its more positive data towards martian environments for when we do go there. And yea, cheap publicity stunt maybe but its still something more solid than "expanding our presence in the solar system and knowledge of the universe" which we are doing more of daily. Really no way to say that without sounding like a smartass i guess.

Are we gonna do the "small step" "giant leap" thing everything man lands on something? lol I hope that's not our motto

Posted by:ihumanity |August 31, 2012 at 08:05 PM

How about this for a first step motto? As the first astronaut steps on whichever planet, moon or unnatural spot for humans to be, he says to all the native life from amoebas and up "Get the hell off of my planet!!".

August 20, 2012 Mars Rover Curiosity Flexes Its Robotic Arm Today

 

          Pia15692-640

 

Curiosity's seven-foot-long (2.1-meter) arm shown above maneuvers a turret of tools including a camera, a drill, a spectrometer, a scoop and mechanisms for sieving and portioning samples of powdered rock and soil.

"We have had to sit tight for the first two weeks since landing, while other parts of the rover were checked out, so to see the arm extended in these images is a huge moment for us," said Matt Robinson of NASA's Jet Propulsion Laboratory, lead engineer for Curiosity's robotic arm testing and operations. "The arm is how we are going to get samples into the laboratory instruments and how we place other instruments onto surface targets."

Weeks of testing and calibrating arm movements are ahead before the arm delivers a first sample of Martian soil to instruments inside the rover. Monday's maneuver checked motors and joints by unstowing the arm for the first time, extending it forward using all five joints, then stowing it again in preparation for the rover's first drive.

"It worked just as we planned," said JPL's Louise Jandura, sample system chief engineer for Curiosity. "From telemetry and from the images received this morning, we can confirm that the arm went to the positions we commanded it to go to."

"We'll start using our sampling system in the weeks ahead, and we're getting ready to try our first drive later this week," said Mars Science Laboratory Deputy Project Manager Richard Cook of JPL.

We know what is on the surface, ROCKS. But, what lies under the dust?

Maybe Curiosity should blast away the dust, to see what is there. And
do it every 3 meters or so. They could pass right over a valuable find
and not even know it. Or is there some limitation of laser usage?

I say dig down at least a 500 millimeters or so, just to see. Maybe,
it will yield something interesting?

2 billion dollars and we cant even get a color photo?

Thanks for this post! You always share the most valuable information. I really appreciate it.Especially "Curiosity's seven-foot-long (2.1-meter) arm shown above maneuvers a turret of tools including a camera, a drill, a spectrometer, a scoop and mechanisms for sieving and portioning samples of powdered rock and soil.

Curiosity's successful landing has really proven to be a big leap for the whole planet. It's the first real exploration of Mars that we have been able to do.

Posted by:Android Application Development |August 21, 2012 at 04:12 AM

the naked truth is scientists can only use the rover 1 minute/day, the rest of the time it`s the army`s use. Editor's Note: This is so absurd, it's almost funny!

August 23, 2012 Mar's Curiosity Mission Gale Crater Landing Site Named in Honor of Ray Bradbury

 

          Curiositytracks_616

 

NASA’s Jet Propulsion Laboratory announced yesterday that it has dubbed the landing site of the Mars rover Curiosity “Bradbury Landing” in honor of sci-fi author Ray Bradbury, who's most popular work was The Martian Chronicles, which portrayed a human invasion of Mars.. It was the Curiosity science team that chose to honor Bradbury, who passed away back in June, and the announcement coincided with what would have been Bradbury’s 92nd birthday.

“This was not a difficult choice for the science team,” said Michael Meyer, NASA program scientist for Curiosity. Bradbury "inspired our curiosity and opened our minds to the possibility of life on Mars."*Bradbury attended Jet Propulsion Laboratory and Caltech events throughout his life, and this week’s announcement was commemorated by the agency with a video of Bradbury reading his poem “If Only We Had Taller Been” at a symposium just before the Mariner 9 orbiter reached Mars in 1971.

and no one deserves it more. I'll bet that at least half of the scientists who made that Mars mission possible were inspired as children (maybe later) by Bradbury's 'The Martian Chronicles'. And I would suggest that we they search for evidence of life there, they might take another look at the Chronicles to remind them that we may not see what is there.

August 18, 2012 'Curiosity' Fires Up Its Laser Beam on 1st Mars Target (Weekend Feature)

 

                            Chemcam2


The Mars Science Laboratory Curiosity rover ChemCam team have received the first photos from the instrument’s remote micro imager. The successful capture of ChemCam’s first 10 photos sets the stage for the first test bursts of the instrument’s rock-zapping laser in the near future.

When ChemCam fires its extremely powerful laser pulse, it briefly focuses the energy of a million light bulbs onto an area the size of a pinhead. The laser blast vaporizes a small amount of its target up to seven meters (23 feet) away.

The resultant flash of glowing plasma is viewed by the system’s 4.3-inch aperture telescope, which sends the light down an optical fiber to a spectrometer located in the body of the rover. There the colors of the light from the flash are recorded, enabling scientists to determine the elemental composition of the vaporized material. ChemCam also has a high-resolution camera that provides close-up images of an analyzed location. It can image a human hair from seven feet away. The ChemCam system is designed to capture as many as 14,000 observations throughout the mission.

 

“The successful delivery of these photos means we can begin efforts in earnest for the first images of Mars rocks by the ChemCam instrument and the first use of the instrument’s laser,” said Los Alamos National Laboratory planetary scientist Roger Wiens, Principal Investigator of the ChemCam Team. “We anticipate these next steps over the weekend.”

The next tasks for ChemCam—the inaugural laser burst and spectral reading—will help scientists determine the integrity of the ChemCam system and the pointing capability of the rover’s mast, which supports ChemCam’s laser and telescope.

Scientists and engineers from NASA’s Curiosity rover mission have selected ChemCam’s first target, a three-inch rock designated N-165 located near the rover.* “Rock N-165 looks like your typical Mars rock, about three inches (seven centimeters) wide and it's about 10 feet away,” Wiens said. “We are going to hit it with 14 milliJoules of energy 30 times in 10 seconds. It is not only going to be an excellent test of our system, but it should be pretty cool too.”

The ChemCam system is one of 10 instruments mounted on the MSL mission’s Curiosity rover—a six-wheeled mobile laboratory that will roam more than 12 miles of the planet’s surface during the course of one Martian year (98 Earth weeks).

The laser, telescope, and camera were provided by the French space agency, CNES, while the spectrometers, electronics, and software were built at Los Alamos National Laboratory, which leads the investigation. The spectrometers were developed with the aid of Ocean Optics, Incorporated, and Jet Propulsion Laboratory assisted with various aspects of development.

Great, our first weapon on Mars... let it be noted; the nanoMartian objected, but was vaporized.

Posted by:dr burke |August 18, 2012 at 06:00 PM

yes dr burke, and thus is the course of nature on practically all scales and in all beings. Don't get it twisted this universe is creation via destruction, and we aren't going to be changing that anytime soon. People are too damn sentimental, they don't comprehend the harsh reality of the universe. As humanity we are nothing, and using our intellect we can learn and our ability to record information we can gather that knowledge together to progress on and on. Any little thing we learn by vaporizing nano-martians is something that progresses our species. Is it "humane"? No, but it is what makes us human. We have exploited the environment in countless ways to achieve what we have, moral or not it's simply what we are, and without doing it, we would be extinct, do not doubt that. Curiosity is the human condition, the human mission. We will dig somethings insides out to find out about it, and not hesitate to go kill a bunch more and eat them if they are safe and taste good (-=

Posted by:Justin |August 18, 2012 at 11:54 PM

It doesnt say how much damage the laser can/did do. Was the 3 inch rock completely vaporized? was there a 2 foot crater made? was the area damaged the size of a coin? I see no reference claiming the rock was vaporized. "The laser blast vaporizes a small amount of its target up to seven meters (23 feet) away." is as close as any reference gets.
And I agree with Justin. If we found a forest there, we would start cutting it down for firewood and shelter our first day there and start testing its fruit and leaves to use as food. Any critters hiding in them would be tested also.

and YES, I know there is no air there for fire, trees ect ect.....

Well, Justin, that is the bleak picture of humanity with which we have justified all kinds of misdeeds....as if we had no choice but to be thoughtless, selfish, and greedy...as if our current version of progress, where millions live in fear, poverty and violence while some who have everything still want more...as if a reasonable definition of development and progress is trashing and destroying whatever we live on, or whoever/whatever lives on land that want. You don't think that human beings can live full, productive lives and continue to evolve in a world where compassion, humaneness, cooperation and moderation are the norm? Clearly, we can live in different worlds even though we inhabit the same planet.

August 22, 2012 NASA's Mars' 'Curiosity Mission' Live Today -- Weather & Water Search Update

 

          1345254375082_1345254375082_r

 

NASA will hold a televised news conference at 11:30 a.m. PDT (2:30 p.m. EDT) today Wednesday, Aug. 22, at the Jet Propulsion Laboratory in Pasadena, Calif., to update on the progress of its Curiosity rover mission focusing on weather and the search for signs of water.

"Curiosity has begun shooting neutrons into the ground," said Igor Mitrofanov of Space Research Institute, Moscow, principal investigator for this instrument, called the Dynamic Albedo of Neutrons, or DAN. "We measure the amount of hydrogen in the soil by observing how the neutrons are scattered, and hydrogen on Mars is an indicator of water."

The most likely hydrogen to be found in shallow ground of Gale Crater, near the Martian equator, is in hydrated minerals. These are minerals with water molecules, or related ions, bound into the crystalline structure of rocks. They can tenaciously retain water from a wetter past after all free water has gone.

The news conference will be broadcast live on NASA TV and online at: http://www.nasa.gov/ntv and http://www.ustream.tv/nasajpl.

This full-resolution image below shows part of the deck of NASA's Curiosity rover taken from one of the rover's Navigation cameras looking toward the back left of the rover.

On the left of this image, part of the rover's power supply is visible. To the right of the power supply can be seen the pointy low-gain antenna and side of the paddle-shaped high-gain antenna for communications directly to Earth. The rim of Gale Crater is the lighter colored band across the horizon. The effects of the descent stage's rocket engines blasting the ground can be seen on the right side of the image, next to the rover.

NASA's Mars rover Curiosity has been investigating the Martian weather around it and the soil beneath it, as its controllers prepare for the car-size vehicle's first drive on Mars.

The rover's weather station, provided by Spain, checks air temperature, ground temperature, air pressure, wind and other variables every hour at the landing site in Gale Crater. On a typical Martian day, or "sol," based on measurements so far in the two-week old mission, air temperatures swing from 28 degrees to minus 103 degrees Fahrenheit (minus 2 to minus 75 Celsius). Ground temperatures change even more between afternoon and pre-dawn morning, from 37 degrees to minus 132 degrees Fahrenheit (3 to minus 91 Celsius).

"We will learn about changes from day to day and season to season," said Javier Gómez-Elvira of the Centro de Astrobiología, Madrid, Spain, principal investigator for the suite of weather sensors called the Rover Environmental Monitoring Station (REMS).

Within a week or so, daily Mars weather reports from Curiosity will become available at: http://cab.inta-csic.es/rems/marsweather.html or http://bit.ly/RzQe6p.

One of the two sets of REMS wind sensors is not providing data. "One possibility is that pebbles lofted during the landing hit the delicate circuit boards on one of the two REMS booms," said Curiosity Deputy Project Scientist Ashwin Vasavada of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We will have to be more clever about using the remaining wind sensor to get wind speed and direction."

An instrument provided by Russia is checking for water bound into minerals in the top three feet (one meter) of soil beneath the rover. It employs a technology that is used in oil prospecting on Earth, but had never before been sent to another planet.

Curiosity will soon have a different patch of ground beneath it. Today, the six-wheeled rover wiggled its four corner wheels side to side for the first time on Mars, as a test of the steering actuators on those wheels. This was critical preparation for Curiosity's first drive on Mars.

"Late tonight, we plan to send Curiosity the commands for doing our first drive tomorrow," said Curiosity Mission Manager Michael Watkins of JPL.

That link to Gale Crater takes you to somewhere on Earth. Here is a correct Goolge Maps link for Mars http://www.google.com/mars/#lat=-11.523087&lon=-52.03125&zoom=2&q=Gale
