Russia and the United States have been sending spacecraft to Mars since 1960! Some of the coolest missions were Mariner 4, 6, 7, & 9, Mars 2, 3, 4, 5, & 6, the Viking missions, and the Mars Global Surveyor mission. You may remember the Mars Pathfinder lander and rover that landed on Mars in 1997. The rover bumped into rocks named Scooby Doo, Shark, Pooh Bear and Chimp!. In April 2001, the 2001 Mars Odyssey was launched. It got to Mars in October 2001. The European Space Agency sent the Mars Express mission to the Red Planet. It reached Mars on Christmas day in 2003. Mars Express also had a small lander called the Beagle 2. NASA launched two Mars Exploration Rovers in June and July of 2003. They have been driving around on Mars since January 2004. Mars Reconnaissance Orbiter is another satellite that is mapping Mars from orbit. It was launched in August 2005 and made it to Mars in March 2006.. The Phoenix Mars Lander was launched in August 2007. It will land near the North Pole of Mars in May ...

A photo of what looks like a squirrel or rat on Mars first released in September 2012 suddenly became a hot topic after Fox News covered the story on May 29. Fox was quickly followed by Discovery News, International Business Times and other major news outlets. It appears that the mainstream news is interested in raising the possibility that the Curiosity Rover is capturing images of life on Mars, even though the coverage is slanted towards dismissing such a possibility. In the meantime NASA has remained silent on photographic evidence of animals on Mars from its own Mars rover instruments. According to NASA, Mars atmosphere is 95% carbon dioxide with only a trace amount of oxygen 0.13% - not enough to sustain animal life on Mars. If Mars atmosphere is inhospitable to life what is the Curiosity Rover photographing on Mars - rocks that look like animals, animal life that has somehow adapted to live in the Martian atmosphere, or Earth animals released in secret NASA experiments on Mars?. The ...

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 Mars Odyssey was launched April 7, 2001, from Florida. After a six-month, 285 million-mile journey, the Odyssey arrived at Mars on October 24, 2001. The Odyssey is in its aerobraking phase right now. After about 3 months of aerobraking, the final science orbit should be achieved and the real science of the mission will start! The Odyssey is carrying a gamma ray spectrometer (GRS). The GRS onboard the Mars Odyssey will help detect the presence of water on the surface of Mars. The GRS will also measure the abundance and distribution of about 20 elements of the periodic table, including silicon, oxygen, iron, magnesium, potassium, aluminum, calcium, sulfur, and carbon at the surface of Mars. Other instruments onboard the Odyssey include the Thermal Emission Imaging System (THEMIS) and the Mars Radiation Environment Experiment (MARIE). MARIE will investigate the amount of radiation present at and around Mars. This would be important information to know if humans were to colonize Mars. THEMIS is ...

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 ...

Remember during the government shutdown when it looked as though a NASA Mars mission would be delayed? Launch preparations continued because delaying the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft - which could have pushed its window back by years - would cause imminent risk to life or property, administrator Charles Bolden told Universe Today in November.. Both NASAs Mars Reconnaissance Orbiter and Mars Odyssey currently provide a vital data link to send huge streams of information from the rovers on the surface, Opportunity and Curiosity. (And the Mars 2020 rover is coming up in a few years, too.) While both orbiters are working well, they are both well over their design lifetimes. MAVEN is now on its way to Mars and should get there in September.. MAVENs mission, however, is only designed to last for a year. While it could last longer, NASA is already thinking ahead for satellite backups - especially for the 2020s. And that could include commercial participation, according ...

An impact crater on Mars has a floor filled with huge blocks of chaotic terrain. THEMIS found the crater contains a thick stack of sediments deposited underwater.. Aram Chaos is an ancient impact crater near the martian equator, close to Ares Vallis. About 280 kilometers (175 miles) across, Aram lies in a region called Margaritifer Terra, where many water-carved channels show that floods poured out of the highlands onto the northern lowlands ages ago.. The Thermal Emission Imaging System (THEMIS) on the Mars Odyssey orbiter mapped the distribution of sediments in Aram Chaos. These sediments include gray crystalline hematite, first found in Aram by the Thermal Emission Spectrometer (TES) on the Mars Global Surveyor spacecraft.. Hematite is an iron-oxide mineral that can precipitate when ground water circulates through iron-rich rocks, whether at normal temperatures or in hot springs.. The floor of Aram contains huge blocks of collapsed, or chaotic, terrain that formed when water or ice was ...

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.\ ...

COVER Morning shadows darken Gusev crater, landing site of the Spirit rover, in this computer-assisted rendering of the ancient martian surface, based on topographic data from the Mars Orbiter Laser Altimeter onboard the Mars Global Surveyor. Discoveries by Spirit, its companion rover Opportunity, and the Surveyor spacecraft confirmed that some areas of Mars were once covered by shallow water and thus could have supported life.

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 ...

New data from THEMIS is helping scientists choose a landing site for the Mars Science Laboratory (MSL), NASAs next-generation rover spacecraft, due for launch in fall 2011.. MSLs mission is to assess whether Mars ever was, or is still today, an environment able to support microbial life. To put it another way, the rovers mission is to determine the planets habitability. MSL will study Martian soil and rock samples and analyze them for organic compounds, the chemical building blocks for life.. At a workshop in fall 2009, scientists chose 4 sites (PDF) as possible landing site locations. Since then, several additional sites have been proposed and after further study, one or more may be added to the four already identified. Scientists are collecting data on these sites to evaluate both their scientific merit and engineering feasibility. NASA will chose the final landing site in spring 2011.. The site-support work at Arizona State Universitys Mars Space Flight Facility seeks to improve our ...

The common feature is the acquisition of three (two spatial and one spectral) dimensional hyperspectral images that allow the mapping of chemical, physical and structural properties. Constant technological improvements promote the acquisition of dramatically expending spectro-image collections. In the field of space exploration for instance, a new generation of imaging spectrometers is emerging with an additional angular dimension for a better characterization of planetary materials and separation of atmospheric versus surface signals. The OMEGA (Observatoire pour la Minéralogie, lEau, les Glaces et lActivité) instrument on the Mars Express orbiter was a precursor since it performs punctual EPF (emission-phase function) observations. The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) on the Mars Reconnaissance Orbiter (MRO) is the first sensor to acquire systematically hyperspectral multi-angle (HMA) data from deep space. These new instruments will again accentuate the size ...

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. ...

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 ...

Mars Rover Beginning To Hate Mars http://www.theonion.com/articles/mars-ro...mars,2072/ PASADENA, CA-NASA Jet Propulsion Laboratory scientists overseeing the ongoing Mars Exploration Rover Mission sai

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 ...

Using a climate model adapted to the special conditions on Mars, researchers believe they can reliably predict snowstorms on Mars far in advance, helping future missions choose better routes that avoid heavy snowfall.. Snowstorms lashing down at the northern hemisphere of Mars during the icy cold winters may be predicted several weeks in advance, say researchers from the Tohoku University in Sendai (Japan) and the Max Planck Institute for Solar System Research (MPS) in Katlenburg-Lindau (Germany) in their newest publication. For the first time, the scientists calculations show a connection between these snowfalls and a special Martian weather phenomenon: fluctuations of pressure, temperature, wind speeds, and directions that in the northern hemisphere propagate in a wave-like manner and occur very regularly. For missions to the red planet exploring this region with rovers, such weather forecasts would offer the possibility of choosing a route that avoids heavy snow storms.. The Martian polar ...

NASAs Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars orbit at 7:24 p.m. PDT (10:24 p.m. EDT) Sunday, Sept. 21, where it now will prepare to study the Red Planets upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.. As the first orbiter dedicated to studying Mars upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet, said NASA Administrator Charles Bolden. It also will better inform a future mission to send humans to the Red Planet in the 2030s.. After a 10-month journey, confirmation of successful orbit insertion was received from MAVEN data observed at the Lockheed Martin operations center in Littleton, Colorado, as well as from tracking data monitored at NASAs Jet Propulsion ...

On Earth, carbon sequestration in geologic units plays an important role in the carbon cycle, scrubbing CO2 from the atmosphere for long-term storage. While carbonate is identified in low abundances within the dust and soils of Mars, at ,1 wt% in select meteorites, and in limited outcrops, no massive carbonate rock reservoir on Mars has been identified to date. Here, we investigate the largest exposed carbonate-bearing rock unit, the Nili Fossae plains, combining spectral, thermophysical, and morphological analyses to evaluate the timing and carbon sequestration potential of rocks on Mars. We find that the olivine-enriched (∼20%-25%) basalts have been altered, by low-temperature in situ carbonation processes, to at most ∼20% Fe-Mg carbonate, thus limiting carbon sequestration in the Nili Fossae region to ∼0.25-12 mbar of CO2 during the late Noachian-early Hesperian, before or concurrent with valley network formation. While this is large compared to modern-day CO2 reservoirs, the lack of ...

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.. Humanitys most sophisticated rover launched July 30 with the Ingenuity Mars Helicopter at 7:50 a.m. EDT on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.. With the launch of Perseverance, we begin another historic mission of exploration, said NASA Administrator Jim Bridenstine. This amazing explorers journey has already required the very best from all of us to get it to launch through these challenging times.

As a mission, as an agency, and as a country, we will persevere.. The ...

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 ...

Nakhla Meteorite Fragment, 1911. Thirty-four meteorites thought to have originated from Mars have been cataloged from around the world, including the Nakhla meteorite.. On June 28, 1911, the Nakhla meteorite fell to Earth at approximately 9 a.m. in the Nakhla region of Alexandria, Egypt. Many people witnessed its explosion in the upper atmosphere before the meteorite dropped in about 40 pieces totaling 22 pounds; the fragments were buried in the ground up to a meter deep.. In August 1911, the Smithsonian received two samples of Nakhla; in 1962, it received the 480-gram piece of the meteorite shown in this photograph. By the 1970s, the Smithsonian had acquired a total of 650 grams of Nakhlas fragments.. Nakhlites, Martian meteorites named for Nakhla, are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago. Their crystallization ages, compared to a crater-count chronology of different regions on Mars, suggest the Nakhlites formed on the large ...

When NASA designed the Mars rover Curiosity as part of their Mars Science Laboratory mission it was created to be able to go anywhere that its mission required it to in the harshest environment that they had ever designed a vehicle for. When Curiosity landed on August 6th, 2012 it was supposed to complete its mission in just two short two years. However, as with many of the space vehicles that NASA designs, it turns out that Curiosity was the little rover that could and has continued to go about its mission to this day, almost four years later. NASA has even extended Curiositys mission indefinitely, and it will continue to collect vital environmental information for the eventual manned mission to Mars that NASA has planned for 2020.. Part of what made the car-sized rover such a durable and long-lasting piece of technology was the basic design of Curiosity itself. The rover has six wheels, each independently powered and maneuverable, allowing it to roll over even the most uneven or rocky ...

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona). Vertical exaggeration is 1.5 ...

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.. The RAD instrument combines charged- and neutral-particle detection capability over a wide dynamic range in a compact, low-mass, ...

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 ...
