The official answer from NASA/JPL is that the Curiosity Mission is designed to find evidence of the conditions for past life on Mars in rocks and soil - e.g., water and chemical compounds necessary for life. Any evidence of current life on Mars is outside the mission parameters of the Curiosity mission. This in itself is noteworthy given evidence that the 1976 Viking Mission conducted tests for life on Mars and the original results were positive, and then deemed inconclusive. The ensuing controversy has not abated with new scientific analysis upholding the original positive results that life was found on Mars.. Also, Dr Thomas Van Flandern former Chief Astronomer for the United States Naval Observatory released his own research findings about photos from the Mars Global Surveyor spacecraft that there was current vegetation on Mars in the form of shrubs, and trees. In an April 5, 2001 Press Conference at the National Press Club, Washington DC., he presented his evidence of vegetation on Mars ...
NASA's Mars Reconnaissance Orbiter suffers glitch, swaps computers, radio transponder, enters safe mode, say Jet Propulsion Laboratory officials
The other buttons make the planets move faster or slower, move backwards, or stop. The date in this simulation is shown above the buttons.. The telescope view in the upper left corner shows how big Mars looks from Earth through a telescope at a given time. The view only shows the size of Mars as viewed from Earth. It does not show how Mars changes in other ways over time, such as Mars spinning on its axis or the changing seasons on Mars.. Beneath the telescope view is a readout of the distance between Earth and Mars. Each time Earth passes close to Mars the event is called an opposition. Notice how the size of Mars as seen through the telescope is not the same at every opposition. The orbit of Mars is not a circle; it is more of an oval in shape. Because an opposition can happen when Mars is at different points in its orbit, the distance at opposition changes, and so does the size of Mars as viewed from Earth. During the opposition in August 2003, Earth and Mars were closer together than ...
PASADENA, CALIF. -- Less than a year since beginning the prime science phase of its mission, NASAs Mars Reconnaissance Orbiter has passed a mission-success milestone for the amount of data returned.. The data-volume target of 26 terabytes, which was surpassed this week, is equivalent to about 5,000 CD-ROMs full and exceeds the total from all other current and past Mars missions combined.. The biggest shares of the data come from two of the orbiters six science instruments: the High Resolution Imaging Science Experiment and the Compact Reconnaissance Imaging Spectrometer for Mars. The high-resolution cameras team of investigators, based at the University of Arizona, Tucson, today released 143 color images. The images reveal features as small as a desk. They are valuable to researchers studying possible landing sites for NASAs Mars Science Laboratory, a mission launching in 2009 to deploy a long-distance rover carrying sophisticated science instruments on Mars.. The camera team is also ...

Gusev Crater is an impact crater on Mars that looks as though a lake may have once filled it in the distant past. One of the two Mars Exploration Rovers (MER) will explore Gusev Crater beginning in January 2004.. Gusev Crater is about 145 km (90 miles) wide and covers an area roughly the size of the state of Connecticut. It is located at 14.6 South latitude and 175.3 East longitude, along the boundary between Mars southern highlands and its lowland northern plains. The crater is about 3,000 km (1,900 miles) southeast of the volcano Elysium Mons. Scientists believe the Gusev Crater was formed by the impact of an asteroid three to four billion years ago.. A valley named Maadim Vallis, which is connected to the south side of the crater, looks like it may have been a river channel that poured water into the crater in the past, forming a large lake. If the crater was indeed a lake, scientists expect it to contain layers of sediments as much as 915 meters (3,000 feet) thick that flowed in with the ...
NASAs Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiositys arm delivered to an analytical laboratory inside the rover.. NASAs Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiositys arm delivered to an analytical laboratory inside the rover.. Detection of the substances during this early phase of the mission demonstrates the laboratorys capability to analyze diverse soil and rock samples over the next two years. Scientists also have been verifying the capabilities of the rovers instruments.. Curiosity is the first Mars rover able to scoop soil into analytical ...
By ALICIA CHANG LOS ANGELES - New photographs from space suggest that water occasionally flows on the frigid surface of Mars, raising the tantalizing possibility that the Red Planet is hospitable to life, scientists reported Wednesday. The new images, taken by NASAs Mars Global Surveyor before it lost contact with Earth, do not actually show flowing water. Rather, they show changes in craters that provide the strongest evidence yet that water coursed through them as recently as several years ago, and is perhaps doing so even now. This is a squirting gun for water on Mars, said Kenneth Edgett, a scientist at San Diego-based Malin Space Science Systems, which operates a camera on the Global Surveyor. The news excited scientists who hunt for extraterrestrial life. If the finding is confirmed, they say, all the ingredients favorable for life on Mars are in place: liquid water and a stable heat source. In all of its Mars exploration missions, NASA has pursued a follow the water strategy to ...
Rover Tracks and Dust Devils on Mars As Seen From Orbit\n\n\The high-resolution camera on NASAs Mars Reconnaissance Orbiter has returned a dramatic oblique view of the Martian crater that a rover explored for two years. The new view of Victoria Crater shows layers on steep crater walls, difficult to see from straight overhead, plus wheel tracks left by NASAs Mars Exploration Rover Opportunity between September 2005 and August 2007. The orbiters High Resolution Imaging Science Experiment camera shot it at an angle comparable to looking at landscape from an airplane window. Some of the cameras earlier, less angled images of Victoria Crater aided the rover team in choosing safe routes for Opportunity and contributed to joint scientific studies.\ ...

This figure shows average temperature structure in the martian northern polar regions in six Mars Years as measured by Mars Climate Sounder on Mars Reconnaissance Orbiter and the Thermal Emission Spectrometer on Mars Global Surveyor. (Mars Year 1 started in 1956; Mars Year 25 started in June 2000; Mars Year 31 started in September 2011.) The profiles cover the atmosphere from the surface up to about 75 kilometers altitude. The profiles are from the aphelion season, when Mars is farthest from the Sun. This coincides with late northern spring (about three weeks before the start of summer). These night-time averages each cover 25 days of observations.
New calculations indicate favorable conditions for small quantities of brine to form during some nights throughout the year on Mars. The possibility for liquid brines on Mars has wider implications for habitability and geological water-related processes.. Martian weather and soil conditions that NASAs Curiosity rover has measured, together with a type of salt found in Martian soil, could put liquid brine in the soil at night.. Perchlorate identified in Martian soil by the Curiosity mission, and previously by NASAs Phoenix Mars Lander mission, has properties of absorbing water vapor from the atmosphere and lowering the freezing temperature of water. This has been proposed for years as a mechanism for possible existence of transient liquid brines at higher latitudes on modern Mars, despite the Red Planets cold and dry conditions.. New calculations were based on more than a full Mars year of temperature and humidity measurements by Curiosity. They indicate that conditions at the rovers ...
A day after an engine anomaly slowed its progress, Indias Mars Orbiter successfully raised its orbit to an apogee above 118,000 km (73,000 mi.) on Nov. 12.. The countrys first Mars orbiter suffered a setback on Nov. 11 as attempts were made to raise the spacecrafts orbit around Earth to built momentum for its trip to Mars. A minor problem with the liquid fuel thruster caused the 1,350-kg (3,000-lb.) vehicle to fall short of the mark.. The fourth supplementary orbit-raising maneuver of Mars Orbiter Spacecraft, starting at 05:03 local time, with a burn time of 303.8 seconds has been successfully completed, Indian Space Research Organization (ISRO) spokesman Deviprasad Karnik says. The observed change in apogee is from 78,276 km to 118,642 km.. The velocity added to the Mars Orbiter was 124.9 meters per second. Everything is normal, Karnik tells Aviation Week.. The Mars Orbiter Mission (MOM) was boosted by a Polar Satellite Launch Vehicle (PSLV-C25) from the Sriharikota spaceport in south ...
The High Resolution Imaging Science Experiment (HiRISE) camera on NASAs Mars Reconnaissance Orbiter caught this view of NASAs Mars Exploration Rover Opportunity on Feb. 14, 2014.
With its solar panels their cleanest in years, NASAs decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of a water-related mineral.. Orbital observations of the site by another NASA spacecraft, Mars Reconnaissance Orbiter, found a spectrum with the signature of aluminum bound to oxygen and hydrogen. Researchers regard that signature as a marker for a mineral called montmorillonite, which is in a class of clay minerals called smectites. Montmorillonite forms when basalt is altered under wet and slightly acidic conditions. The exposure of it extends about 800 feet (about 240 meters) north to south on the western rim of Endeavour Crater, as mapped by the orbiters Compact Reconnaissance Imaging Spectrometer for Mars (CRISM).. Its like a mineral beacon visible from orbit saying, Come check this out, said Opportunity Principal Investigator Steve Squyres, of Cornell University, Ithaca, New York.. Some of the ...
similar, temperature-driven winds arise as sublimation of frost covering sun-facing slopes and dark sandy surfaces deep within the polar region creates intense slope winds away from the higher-standing layered deposits and permanent cap. The roughly circular, polar orbit of the Mars Global Surveyor (MGS) spacecraft affords a view not unlike that seen by low Earth-orbiting environmental satellites. Mars is roughly 6800 km (4226 mi) in diameter, and a 370 km (230 mi) average altitude gives a diameter to altitude ratio for MGS of 18.4:1. For comparison, the SeaStar spacecraft in Earth orbit follows a very similar orbit: its the diameter to altitude ratio is 17.5:1 (12,760 km or 7,928 mi diameter relative to a 705 km or 438 mi altitude). Each spacecraft covers the entire planet in 12 orbits.. In this figure, we compare a recent dust storm on Mars with one that occurred earlier this year on Earth. The top image shows a martian north polar dust storm observed on 29 August 2000. This image is part of ...
I scrolled through the posts before pasting and copying the text below, which I read in an article pertaining initially to Titan (and posted in the Huygens Probe to Titan thread by me a few days ago). The relation to Mars is in the 3rd paragraph:. Although Titans underlying surface is thought to be water ice, the complex chemistry in the upper atmosphere might have resulted in the icy surface being at least partly covered in liquid ethane and methane and solid hydrocarbons. One class of the solid hydrocarbons, often referred to as Titan tholins (from the Greek word, muddy), was artificially created in a laboratory by a team led by the late Cornell astronomer Carl Sagan.. When scientists analyze the building blocks of tholins by burning them (pyrolysis), splitting up the tholins using plasma, scientists find a rich array of biomolecular building blocks such as pyrroles, pyrazines, pyridines and pyrimidines.. All of these molecules have played an important role in the evolution of terrestrial ...
The Curiosity Mars rover is in the prime of its robotic life, approaching dramatic layered deposits on the slopes of Mt. Sharp. But even as the four and a half year-old mission reaches the features it was initially sent to investigate, scientists and engineers are feverishly planning for the next rover mission, Mars 2020.. 2020 is shaping up to be a busy year on the Mars exploration calendar: in addition to the NASA rover, the European Space Agency and China have missions slotted for the favorable launch window. But where to go? Making the decision is a complex process, as teams of scientists and engineers develop navigational software, optimize the payload, and establish the geologic context of potential landing sites.. The importance of site selection is magnified by the role of Mars 2020 as the first step in a sample return mission - a longtime grail of Mars scientists. In its current configuration, the rover can collect about 30 canisters of soil, air, or rock particles. A future, ...
The huge successes of the two Viking Landers, the Pathfinder Lander with Sojourner, the Mars Exploration Rovers, Spirit and Opportunity, and the Phoenix Lander have opened a new era in the exploration of Mars. The Viking Landers could not determine if life is present or ever was present on Mars, but did uncover clues that Mars had a warmer, wetter past. The Sojourner Rover proved that driving a wheeled vehicle on Mars was possible and found that the geological chemistry varied the more it roamed. The Opportunity Rover confirmed that Mars did indeed have water and in many places there were shallow pools or perhaps seas in its past. Where there was water, there may have been life or may still be. Sedimentary rocks on Earth leave a record of past life and only certain environments and types of deposits provide good places for fossil preservation. The challenge is to determine life from non-life as any life on Mars could potentially have a different chemistry, structure, and characteristics than on ...
ABSTRACT. Two Miniature Thermal Emission Spectrometers (Mini-TES) operated successfully onboard the two Mars Exploration Rovers (MER) on the Martian surface, one at Gusev crater and the other at Meridiani Planum. Designed to provide remotely sensed information on the bulk mineralogy of surface materials, the Mini-TES instruments served to guide the rovers to targets of interest and extrapolate the observations made by the rovers mechanical-arm-mounted instruments. The Mini-TES on the Spirit rover in Gusev crater observed a flat plain covered by rocks with an olivine-rich ((Mg,Fe)2SiO4) mineralogy and a soil-like unit mantled by airfall dust occurring between the rocks. The dust is a spectral match to dust observed at Meridiani Planum and across the globe. The soil is basaltic in composition, dominated by plagioclase (NaAlSi3O8-CaAl2Si2O8), pyroxene (Ca(Mg,Fe)Si2O6-(Mg,Fe)SiO3), and olivine that probably was produced in part from the breakdown of local rocks. Approximately 2.5 km from the Spirit ...
Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planets surface. Yet, the ancient sun was about one-third less warm and climate modelers struggle to produce scenarios that get the surface of Mars warm enough for keeping water unfrozen.. A leading theory is to have a thicker carbon-dioxide atmosphere forming a greenhouse-gas blanket, helping to warm the surface of ancient Mars. However, according to a new analysis of data from NASAs Mars rover Curiosity, Mars had far too little carbon dioxide about 3.5 billion years ago to provide enough greenhouse-effect warming to thaw water ice.. The same Martian bedrock in which Curiosity found sediments from an ancient lake where microbes could have thrived is the source of the evidence adding to the quandary about how such a lake could have existed. Curiosity detected no carbonate minerals in the samples of the bedrock it analyzed. The new analysis concludes that the ...
Mars Pathfinder - USA Lander & Surface Rover - 264 kg (lander), 10.5 kg (rover) - (December 4, 1996 - September 27, 1997) Mars Pathfinder arrived at Mars on July 4, 1997 and impacted the surface at 16:57 UT (12:57 PM EDT) at a velocity of about 18 m/s (40 mph). It bounced about 15 meters (50 feet) into the air, bouncing another 15 times and rolling before coming to rest approximately 2.5 minutes after impact and about 1 km from the initial impact site. The landing site was in the Ares Vallis region is at 19.33 N, 33.55 W and was named the Sagan Memorial Station. A six-wheel rover, named Sojourner, rolled onto the Martian surface on July 6 at about 05:40 UT. Mars Pathfinder returned 2.6 billion bits of information, including more than 16,000 images from the lander and 550 images from the rover, as well as more than 15 chemical analyses of rocks and extensive data on winds and other weather factors. The last successful data transmission was on September 27, 1997, the 83rd day of the mission since ...
NASA and Arizona State University?s Mars Education Program is offering students nationwide the opportunity to be involved in authentic Mars research by participating in the Mars Student Imaging Project (MSIP). Teams of students in grades 5 through college sophomore level will have the opportunity to work with scientists, mission planners and educators on the THEMIS team at ASU?s Mars Space Flight Facility, to image a site on Mars using the THEMIS visible wavelength camera onboard the Mars Odyssey spacecraft which is currently orbiting Mars every 2 hours ...
Follow along on a tour of the landing scene of NASAs Curiosity rover in this video made up of images from two NASA orbiters. The movie begins with a global image from NASAs Mars Global Surveyor, then switches to views from the High Resolution Imaging Science Experiment (HiRISE) on NASAs Mars Reconnaissance Orbiter. As we zoom closer and closer into Gale Crater, the components of Curiositys landing system come into view: The heat shield was the first piece to hit the ground, followed by the back shell attached to the parachute, then the rover itself touched down, and finally, after cables were cut, the sky crane flew away to the northwest and crashed.

Thousands of meteors per hour would have been visible - truly astounding to the human eye. Thats Nick Schneiders description of what you and I would have seen standing on Mars during Comet Siding Springs close flyby last month. It would have been really mind-blowing, he added. Schneider is instrument lead for MAVENs Imaging Ultraviolet Spectrograph (IUVS).. He and a group of scientists who work as lead investigators for instruments on the MAVEN and Mars Reconnaissance Orbiter (MRO) spacecraft shared the latest results from the comet flyby during a media teleconference earlier today. There were many surprises. Would we expect anything less from a comet?. Heres a summary of the results:. A very dusty ice ball - The comets dust tail and the amount of dust in its coma were much larger than expected, prompting Jim Green, director of NASAs Planetary Science Division in Washington, to remark: It makes me very happy we hid them (the spacecraft) on the backside of Mars. That really saved ...
Prior to Mars Reconnaissance Orbiter data, images of Mars showed no direct evidence for dune and ripple motion. This was consistent with climate models and lander measurements indicating that winds of sufficient intensity to mobilize sand were rare in the low-density atmosphere. We show that many sand ripples and dunes across Mars exhibit movement of as much as a few meters per year, demonstrating that Martian sand migrates under current conditions in diverse areas of the planet. Most motion is probably driven by wind gusts that are not resolved in global circulation models. A past climate with a thicker atmosphere is only required to move large ripples that contain coarse grains. ...
Pillinger was the principal investigator for the Beagle 2 Mars lander project, part of European Space Agencys (ESA) 2003 Mars Express mission. Initially considered a failure, it has since come to light that the space craft did successfully touch down on the surface of Mars. The UK Space Agency on 16 January 2015 indicated that Beagle 2 had indeed reached the surface of Mars on 25 December 2003, but had failed to deploy fully.[17] Images taken by the HiRISE camera on NASAs Mars Reconnaissance Orbiter (MRO) identified clear evidence for the lander and convincing evidence for key entry and descent components on the surface of Mars within the expected landing area of Isidis Planitia (an impact basin close to the equator). Recent research into photographs taken of the landing site by a Mars orbiter suggest that as many as three of the four solar panels may have been successfully opened. The reason why the lander failed to communicate back to Earth has not yet been determined. When the lander was ...
View more images The south polar layered deposits of Mars cover an area bigger than Texas. The amount of water they contain has been estimated before, but never with the level of confidence this radar makes possible, said Jeffrey Plaut of NASAs Jet Propulsion Laboratory, Pasadena Calif. Plaut is co-principal investigator for the radar and lead author of a new report on these findings published in the March 15 online edition of the journal Science. The instrument, named the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS), also is mapping the thickness of similar layered deposits at the north pole of Mars. Our radar is doing its job extremely well, said Giovanni Picardi, a professor at the University of Rome La Sapienza, and principal investigator for the instrument. MARSIS is showing itself to be a very powerful tool to probe underneath the Martian surface, and its showing how our teams goals, such as probing the polar layered deposits, are being successfully ...
The Mars Exploration Rover Opportunity strolled out of her winter haven this May to continue the expedition around Endeavour Crater, roving into yet another Martian spring.
Odyssey was launched April 7 from Cape Canaveral Air Force Station, Florida. Other than our Moon, Mars has attracted more spacecraft exploration attempts than any other object in the solar system, and no other planet has proved as daunting to success. Of the 30 missions sent to Mars by three countries over 40 years, less than one-third have been successful. The spacecraft, ground system and flight team are ready for Mars orbit insertion, said Matthew Landano, Odyssey project manager at NASAs Jet Propulsion Laboratory, Pasadena, California. We uplinked the sequence of commands that control the orbit insertion on October 15. Now we will closely monitor the spacecrafts progress as it approaches Mars and executes the orbit insertion burn.. ...
To many NASA observers, it may seem self evident that the Mars Rovers are a shining icon of our engineering prowess that all of humanity can be proud of, in the same way as we are proud of the achievements of Neil Armstrong and Buzz Aldrin. But scientifically and technically, what is the main aim of these missions? I would argue that the chief objective of the NASA Mars Exploration Program is to open human hearts to the Martian frontier and focus the efforts of our best and brightest minds on the goal of exploring the nearest inhabitable planet in our Universe.. For example, SpaceX was founded in 2002, in the midst of the excitement of the 2003 MER missions, Spirit and Opportunity. If these rovers had been cancelled or failed to launch, would Elon Musk and his 1,800 employees, some of the nations best and brightest, be around today working on spacecraft and launch vehicles that could one day take us to Mars?. A second example is relevant: if the Mars Exploration program is discontinued or ...
SHARAD is a subsurface sounding radar aboard NASAs Mars Reconnaissance Orbiter, capable of detecting dielectric discontinuities in the subsurface caused by compositional and/or structural changes. Echoes coming from the surface contain information on geometric properties at metre scale and on the permittivity of the upper layers of the Martian crust. A model has been developed to estimate the effect of surface roughness on echo power, depending on statistical parameters such as RMS height and topothesy. Such model is based on the assumption that topography can be characterized as a self-affine fractal, and its use allows the estimation of the dielectric properties of the first few metres of the Martian soil. A permittivity map of the surface of Mars is obtained, covering several large regions across the planet surface. The most significant correspondence with geology is observed at the dichotomy boundary, with high dielectric constant on the highlands side (7 to over 10) and lower on the lowlands side
The surface of the planet Mars appears reddish from a distance because of rusty dust suspended in the atmosphere. From closeup, it looks more of a butterscotch, and other common surface colors include golden, brown, tan, and greenish, depending on minerals. The apparent colour of the Martian surface enabled humans to distinguish it from other planets early in human history and motivated them to weave fables of war in association with Mars. One of its earliest recorded names, Har decher, literally meant Red One in Egyptian. Its color may have also contributed to a malignant association in Indian astrology, as it was given the names Angaraka and Lohitanga, both reflecting the distinctively red color of Mars as seen by the naked eye. Modern robotic explorers have shown that not only the surfaces, but also the skies above may appear red under sunlit conditions on Mars. Modern observations indicate that Marss redness is skin deep. The Martian surface looks reddish primarily because of a ubiquitous ...
By mimicking those conditions, we got the microbes to repeat that behavior in the laboratory, Fisk added.. The microbes were collected from a lava tube near Newberry Crater in Oregons Cascades Mountains, at an elevation of about 5,000 feet. They were within the ice on rocks some 100 feet inside the lava tube, in a low-oxygen, near-freezing environment. Scientists, including Fisk, have said that the subsurface of Mars could have similar conditions and harbor bacteria.. In fact, Fisk has examined a meteorite originating from Mars that contained tracks - which could indicate consumption by microbes - though no living material was discovered. Similar tracks were found on the rocks from the Newberry Crater lava tube, he said.. Conditions in the lava tube are not as harsh as on Mars, Fisk said. On Mars, temperatures rarely get to the freezing point, oxygen levels are lower and at the surface, liquid water is not present. But water is hypothesized to be present in the warmer subsurface of Mars. ...
Comet C/2013 A1 Siding Spring will make a close flyby of Mars on Oct. 19, 2014. At a distance of only 87,000 miles - about 1/3 the distance between the Earth and moon - its a near miss of the Red Planet. Find out how NASAs Mars orbiters will evade dust from the comet. Transcript:. (Music). Don Yeomans:. This is going to be an opportunity to observe a brand new comet and we noted immediately that its going to make a very close approach to Mars on Oct. 19th.. Zurek:. When we first heard about the comet and that it was coming very close to Mars, we had so little tracking information that there was a possibility it could hit Mars.. Lock:. The accuracy of the trajectory started to improve and we realized it wasnt going to hit Mars but still might provide a threat to our spacecraft there.. (Music). Zurek:. This is a first time visitor from the outer solar system, from the Ort Cloud. Thats coming in close to where we can see it and close enough that its actually encountering Mars.. Lock:. Comets ...
A few things need to be pointed out here. Going to Mars is not easy. Between now and the 2020 election, there is exactly one launch window - Dec 2019. They occur about every 26 months. It takes 6 months to transit to Mars, so a landing in May 2020 or so.. Now, it needs to be noted that we dont have a rated manned spacecraft to get to the ISS. We might have one by June or so. But that craft cant keep a human alive for the 6 month journey to Mars. Whats more, we dont have a human rated launcher that can get that craft to Mars. The SLS is the vehicle we expect to fill that role, which might be ready for a first launch in June 2020. But lets be serious here - its years late, and will be years more late. Further, Keeping a human alive for the trip to Mars requires a quantity of radiation shielding and life support that even it wont be able to lift a craft from Earth to Mars. Itll need to be done in 2 steps - put it in earth orbit, outfit it, then send it to Mars. Well need about 10t of mass ...
Astronomers use new craters on Mars to see beneath the dust blanket and determine the underlying rock compositions and textures.. Mars is a dynamic planet. HiRISE has witnessed many surface changes over the past ten years, including hundreds of new craters formed by ongoing impacts. Most of these impacts are likely caused by asteroids that have strayed into collision courses with Mars. The planets much thinner atmosphere compared to Earth makes small asteroids less likely to burn up prior to hitting the Martian surface.. This new crater, which formed explosively at the point of impact, has a diameter of roughly 8 meters (about 25 feet), but its surrounding blast zone and ejecta extend over a kilometer (about one mile) beyond the crater itself. The materials exposed nearest the crater have distinctive yellowish and lighter grey appearances, while more distant ejected materials range from dark brown to bright bluish in an enhanced-color view. These varied materials may have originated from ...
NASAs Mars Curiosity has debuted the first recorded human voice that traveled from Earth to another planet and back.. In spoken words radioed to the rover on Mars and back to NASAs Deep Space Network (DSN) on Earth, NASA Administrator Charles Bolden noted the difficulty of landing a rover on Mars, congratulated NASA employees and the agencys commercial and government partners on the successful landing of Curiosity earlier this month, and said curiosity is what drives humans to explore.. 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 voice playback was released along with new telephoto camera views of the varied Martian landscape ...
Amino acids are excellent biomarkers in the search for life on Mars because they are essential for biology as we know it and they are robust enough to survive for billions of years in the cold and dry Martian environment. However, amino acids and other organic compounds on Mars are exposed to the ionizing radiation from space and from the decay of radionuclides. This process and its role in the preservation of organic compounds has not been adequately addressed in the past. Based on measured radiolysis constants of amino acids and radiation dose estimates for Mars we show that the detection of an amino acid signature derived from an early Martian biosphere is not limited by its radiolytic decomposition as long as the amino acids are shielded adequately from space radiation. This indicates clearly the need to access the Martian subsurface in the search for molecular traces of an extinct Martian biosphere. (c) 2006 Elsevier B.V. All rights reserved.. ...
David Shiga writes, NASAs silent Mars Global Surveyor (MGS) spacecraft is likely lost forever. The space agency attempted to take a picture of the 10-year-old spacecraft using the newer Mars Reconnaissance Orbiter, but did not detect it, either because its orbit has shifted since last contact, or ...
25 January 2007 Rather than having had its air knocked out into space, Mars might just be holding its breath. New findings suggests the missing atmosphere of Mars might be locked up in hidden reservoirs on the planet, rather than having been chafed away by billions of years worth of solar winds as previously thought. Combining two years of observations by the European Space Agencys Mars Express spacecraft, researchers determined that Mars is currently losing only about 20 grams of air per second into space. Extrapolating this measurement back over 3.5 billion years, they estimate that only a small fraction, 0.2 to 4 millibars, of carbon dioxide and a few centimeters of water could have been lost to solar winds during that time frame. (A bar is a unit for measuring pressure; Earths atmospheric pressure is about 1 bar.) Missing Greenhouse According to the warm and wet early Mars model, liquid water once flowed on the red planets surface. Evidence from channels and gullies recently spotted on ...
Only in the past couple of decades has the extent to which life on Earth has colonized, evolved and thrived in a variety of deep ecosystems become evident. For example, recently a thermophilic anaerobic member of the genus Bacillus was obtained from a depth of about 2,700 metres below the surface in Virginia. If Earth is any guide, the question of life on Mars will remain very open until we have at least explored all the areas on Mars equivalent to those on Earth where life has been found. ...
On July 30, 1976, the LR returned its initial results from Mars. Amazingly, they were positive. As the experiment progressed, a total of four positive results, supported by five varied controls, streamed down from the twin Viking spacecraft landed some 4,000 miles apart. The data curves signaled the detection of microbial respiration on the Red Planet. The curves from Mars were similar to those produced by LR tests of soils on Earth. It seemed we had answered that ultimate question. When the Viking Molecular Analysis Experiment failed to detect organic matter, the essence of life, however, NASA concluded that the LR had found a substance mimicking life, but not life. Inexplicably, over the 43 years since Viking, none of NASAs subsequent Mars landers has carried a life detection instrument to follow up on these exciting results. Instead the agency launched a series of missions to Mars to determine whether there was ever a habitat suitable for life and, if so, eventually to bring samples to Earth ...

Trace amounts of glycine, serine, and alanine were detected in the carbonate component of the martian meteorite ALH84001 by high-performance liquid chromatography. The detected amino acids were not uniformly distributed in the carbonate component and ranged in concentration from 0.1 to 7 parts per million. Although the detected alanine consists primarily of the L enantiomer, low concentrations (|0.1 parts per million) of endogenous D-alanine may be present in the ALH84001 carbonates. The amino acids present in this sample of ALH84001 appear to be terrestrial in origin and similar to those in Allan Hills ice, although the possibility cannot be ruled out that minute amounts of some amino acids such as D-alanine are preserved in the meteorite.
The risk that Mars may be contaminated by microorganisms transported from Earth on spacecraft will depend on four key factors: (i) survival of viable microorganisms during transit from Earth launch to Mars landing, (ii) dispersal of viable microorganisms away from landed or crashed vehicles, (iii) long-term survival of dispersed microbes on Mars, and (iv) the ability of dispersed microorganisms to undergo replicative growth in the Mars surface environment (50). Significant literature supports the conclusion that viable microorganisms have survived launch and transport to Mars (44, 47, 53). Dispersal mechanisms of viable microbes away from landed or crashed spacecraft on Mars have not been adequately studied and remain significant black boxes in any Mars microbial survival and proliferation model. Long-term survival on Mars is unlikely if microbes are directly exposed to solar UV irradiation (11, 37, 47, 49, 50) but likely if the microbes are protected from UV irradiation by thin dust layers or ...
A dune in the northern polar region of Mars shows significant changes between two images taken on June 25, 2008 and May 21, 2010 by NASAs Mars Reconnaissance Orbiter. This motion includes landslides and sand advancing at the dune front (upper left); changes in the position of the rest of the dune boundary relative to the fixed, underlying terrain; and changes in the position of ripples on the dune surface. This is one of several sites where the orbiter has observed shifting sand dunes and ripples. Previously, scientists thought sand on Mars was mostly immobile. It took the missions High Resolution Imaging Science Experiment (HiRISE) to take sharp enough images to finally see the movement. While dust is easily blown around the Red Planet, its thin atmosphere means that strong winds are required to move grains of sand. The Mars Reconnaissance Orbiter is managed by NASAs Jet Propulsion Laboratory for NASAs Science Mission Directorate in Washington. The University of Arizonas Lunar and Planetary
According to one version of the panspermia theory, life on Earth could originally have arrived here by way of meteorites from Mars, where conditions early in the history of the solar system are thought to have been more favorable for the creation of life from nonliving ingredients. The only problem has been how a meteorite could get blasted off of Mars without frying any microbial life hitching a ride.. But new research on the celebrated Martian meteorite ALH84001 shows that the rock never got hotter than 105 degrees Fahrenheit during its journey from the Red Planet to Earth, even during the impact that ejected it from Mars, or while plunging through Earths atmosphere before landing on Antarctic ice thousands of years ago.. In the October 27 issue of the journal Science, Caltech graduate student Benjamin Weiss, undergraduate student Francis Macdonald, geobiology professor Joseph Kirschvink, and their collaborators at Vanderbilt and McGill universities explain results they obtained when ...

This cross-section view of underground layers near Mars south pole is a radargram based on data from the Shallow Subsurface Radar (SHARAD) instrument on NASAs Mars Reconnaissance Orbiter. Researchers interpret the zone that is nearly free of radio-wave reflections (hence dark in the radargram) to be composed of frozen carbon dioxide, or dry ice.. The newly found deposit of dry ice contains enough carbon dioxide to dramatically increase the total amount of atmosphere on Mars when the frozen carbon dioxide vaporizes, as climate models suggest it does at times when the planets tilt increases. Mars current atmosphere is about 95 percent carbon dioxide, and this deposit contains up to about 80 percent as much carbon dioxide as the atmosphere does.. This cross section covers a transect about 330 kilometers (205 miles) long in a region from about 86 degrees to 87 degrees south latitude and 280 degrees to 10 degrees east longitude. The vertical dimension of the graphic is time delay of the radar ...

Morphological Biosignatures and the Search for Life on Mars Determining the location of potential paleobiological repositories on Mars requires an understanding of the martian surface in terms of elemental abundances and mineralogy. This variety of hematite on Earth forms only in the presence of large amounts of water, and typically at elevated (hydrothermal) temperatures (Christensen et al., 2000). http://geology.asu.edu/jfarmer/pubs/pdfs/morpho.pdf It is this common association of microbes and iron deposition on earth that has spurred hopes that robot crafts exploring the hematite anomaly of Mars Meridiani Planum might find evidence for ancient life. The hematite deposits of Meridiani Planum [7], regardless of their exact origin, are considered to be a favorable host for microorganisms that might have been associated with their formation [8]. http://www.lpi.usra.edu/meetings/lpsc2004/pdf/1369.pdf The Stromatolites of Stella Maris, Bahamas http://www.theflyingcircus.com/stella_maris.html ...

Ice sheet elevation changes have been measured by repeat airborne laser altimetery in Greenland since 1991. The Airborne Topographic Mapper (ATM) system, which has been mounted in a NASA P-3 aircraft, includes a scanning laser altimeter, INS and differential GPS. During the post-processing the measured data are converted into measurements of ice sheet elevation relative to the Earth ellipsoid (Krabill et aI., 1995). Since laser scanner data sets are composed of a huge amount of points, obtaining the swath contour and locating overlapping areas between different swaths in an efficient way is not a simple task. To make this task more feasible a thinned data set called ICESS has been created from the laser data collected over the Greenland ice sheet (Martin, 1997). Since the surface is reasonably smooth, the laser swath was modeled as a series of planes, each characterized by a center elevation, a north-south slope, and an east-west slope. However, for many applications such as mapping the rough ...
The National Aeronautics and Space Administration (NASA) Mars 2020 Perseverance rover mission is on its way to the Red Planet to search for signs of ancient life and collect samples to send back to Earth, and technologies from three Department of Energy (DOE) national labs will help it get there..

NWA 2737, a Martian meteorite from the Chassignite subclass, contains minute amounts (0.010 ± 0.005 vol%) of metal-saturated Fe-Ni sulfides. These latter bear evidence of the strong shock effects documented by abundant Fe nanoparticles and planar defects in Northwest Africa (NWA) 2737 olivine. A Ni-poor troilite (Fe/S = 1.0 ± 0.01), sometimes Cr-bearing (up to 1 wt%), coexists with micrometer-sized taenite/tetrataenite-type native Ni-Fe alloys (Ni/Fe = 1) and Fe-Os-Ir-(Ru) alloys a few hundreds of nanometers across. The troilite has exsolved flame-like pentlandite (Fe/Fe + Ni = 0.5-0.6). Chalcopyrite is almost lacking, and no pyrite has been found. As a hot desert find, NWA 2737 shows astonishingly fresh sulfides. The composition of troilite coexisting with Ni-Fe alloys is completely at odds with Chassigny and Nahkla sulfides (pyrite + metal-deficient monoclinic-type pyrrhotite). It indicates strongly reducing crystallization conditions (close to IW), several log units below the fO2 conditions ...

What makes carbon-based organic compounds especially interesting to scientists is that life is made of them and produces them. So one source of the organics in Martian samples could be biology, Eigenbrode said. But she said there were other potential sources that might be more plausible.. Organics, for instance, can be formed through non-biological geothermal and hydrothermal processes on Earth, and presumably on Mars too. In addition, both meteorites and interstellar dust are known to contain organic compounds, and they rain down on Mars as they do on Earth.. Eigenbrode said the organics being detected could be coming from any one source, or from all of them.. Asked at the workshop what concentrations of organics were found, she replied with a grin that more light will be shed on the question at next weeks American Geophysical Union meeting.. The detection of a growing variety of organics on Mars adds to the conclusion already reached by the Curiosity team - that Mars was once much wetter, ...
We present an analysis of two concentrically-fractured depressions on Mars, one in northern Hellas and the second in Galaxias Fossae. Volumetric measurements indicate that ∼2.4 km3 and ∼0.2 km3 of material was removed in order to form the North Hellas and Galaxias depressions. The removed material is inferred to be predominantly water ice. Calorimetric estimates suggest that up to ∼103-105 m3 of magma would have been required to melt/sublimate such a volume of ice under an ice/magma interaction scenario. This process would lead to subsidence and cracking of the surface, which could produce the observed concentric fracture (crevasse-like) morphology. While the Galaxias Fossae landform morphology is consistent with an impact origin, the large volume of removed material in North Hellas is less consistent with an impact origin and is interpreted to have resulted from volcanic melting of ice. The possibility of liquid water formation during or subsequent to volcanism or an impact could generate ...
Figure: The RAD Instrument.. The Radiation Assessment Detector (RAD) is an investigation to detect and analyze the most biologically hazardous energetic particle radiation on the Martian surface as part of the Mars Science Laboratory (MSL) mission. It has made the first-ever direct radiation measurements on the surface of Mars, detecting galactic cosmic rays, solar energetic particles, secondary neutrons, and other secondary particles created both in the atmosphere and in the Martian regolith. The radiation environment on Mars is a key life-limiting factor that directly affects habitability and the ability to sustain life, and poses a challenge for future human explorers on the red planet. Thus, RAD measurements help planning for future human exploration and give us a direct measure of what levels of radiation to expect when we send astronauts to Mars in the future..

A proxy filed last week said that if Wrigley backs out of the $23 biillion deal, it now would have to pay Mars $690 million. On the other hand, if Mars pulls out it must pay $1 billion to Wrigley.. Mars raised its per share bid after Wrigley said the initial offer of $76 per share was too low. On April 17, Mars raised the bid to $77 per share, but later made a final offer of $80 per share. Wrigley accepted and a merger agreement was announced April 28.. Reports said that a recent meeting between Wrigley chairman, William Wrigley Jr., Mars president, Paul S. Michaels, and Mars chief financial officer, Olivier C. Goudet, went smoothly.. Michaels and Goudet also said that this was a friendly proposal to be discussed on an exclusive basis and that Mars would withdraw its proposal if the board of directors of the company was not interested in pursuing the combination or if the company wanted to conduct any type of auction process, the statement said.. Other details of the change include Mars plans ...

We measured maps of atmospheric water (H2O) and its deuterated form (HDO) across the martian globe, showing strong isotopic anomalies and a significant high deuterium/hydrogen (D/H) enrichment indicative of great water loss. The maps sample the evolution of sublimation from the north polar cap, revealing that the released water has a representative D/H value enriched by a factor of about 7 relative to Earths ocean [Vienna standard mean ocean water (VSMOW)]. Certain basins and orographic depressions show even higher enrichment, whereas high-altitude regions show much lower values (1 to 3 VSMOW). Our atmospheric maps indicate that water ice in the polar reservoirs is enriched in deuterium to at least 8 VSMOW, which would mean that early Mars (4.5 billion years ago) had a global equivalent water layer at least 137 meters deep.. ...
MVL, Ph.D. Candidate. ABSTRACT. Discoveries during an investigation of the solid oxide electrolysis cells for the Mars Oxygen ISRU Experiment As humankind expands its footprint in the solar system, it is increasingly important to make use of Earth independent resources to make these missions economically feasible and sustainable. In-Situ Resource Utilization (ISRU), the science of using resources at a destination to support exploration missions, unlocks potential destinations by significantly reducing the amount of resources that need to be launched from Earth. Carbon dioxide is an example of an in-situ resource that comprises nearly 96% of the Martian atmosphere and can be used as a source of oxygen for propellant and life support systems. The Mars Oxygen ISRU Experiment (MOXIE) is a payload being developed for NASAs upcoming Mars 2020 rover. MOXIE will produce oxygen at a rate of 10 grams per hour from the Martian atmosphere using solid oxide electrolysis (SOXE). MOXIE is a 0.5% scale of an ...
Astronauts on missions to deep space such as Mars may face severe medical emergencies like heart attacks, say experts who suggest that the crew must prepare to deal with potentially fatal illnesses or injuries. Experts at the Euroanaesthesia Congress in Geneva discussed the unusual and challenging problem of how to perform emergency medical procedures during space missions. Space exploration missions to the Moon and Mars are planned in the coming years. During these long duration flights, the estimated risk of severe medical and surgical events, as well as the risk of loss of crew life are significant, said Matthieu Komorowski, from the Charing Cross Hospital in the UK.. In the event of a crew member suffering from an illness or injury, they may have to be treated by personnel with little formal medical training and without the equipment that would be available in a comparable situation on Earth. In the worst-case scenario, non-medical personnel may have to care for an injured or ill ...

The depth to which solar radiation can penetrate through ice is an important factor in understanding surface‐atmosphere interactions for icy planetary surfaces. Mars hosts both water and carbon dioxide ice on the surface and in the subsurface. At high latitudes during autumn and winter carbon dioxide condenses to form the seasonal polar cap. This has been both modelled and observed to, in part, occur as snowfall. As snow accumulates, the thermal properties of the surface are changed, whether the underlying surface was rocky, regolith or a solid ice sheet. This results in a change (usually increase) in albedo, affecting the proportion of the incident solar energy reflected, or transmitted below the surface of the snow layer. The depth to which light can penetrate through this layer is an important parameter in heat transfer models for the Martian surface, and is often quantified using the e‐folding scale. We present the first measurements of the e‐folding scale in pure carbon dioxide snow ...
