    Dr. Danielle N. Lee, who writes for the Scientific American blog network and calls herself "the Urban Scientist," believes that the push to visit Mars and eventually inhabit it is "white colonialism." Dr. Lee expressed her concerns in both the Scientific American blog and on Twitter. Writing in Scientific American in an article titled, "When discussing Humanity’s next move to space, the language we use matters," Dr. Lee discusses Elon Musk's push to inhabit Mars some day. She is very critical of Musk, saying that his language is not inclusive enough to either women and minorities. "Diversity, Inclusion, Access and...

    At 8.45 on the morning of 15 April 136 BC, Babylon was plunged into darkness when the Moon passed in front of the Sun. An astrologer, who recorded the details in cuneiform characters on a clay tablet, wrote: "At 24 degrees after sunrise-a solar eclipse. When it began on the southwest side, Venus, Mercury and the normal stars were visible. Jupiter and Mars, which were in their period of disappearance, became visible. The Sun threw off the shadow from southwest to northeast." If present-day astronomers use a computer to run the movements of the Earth, Moon and Sun backwards...

    Six years from now a machine that makes oxygen will be in operation on Mars. The small oxygen device will be sent to the Red Planet with the NASA Mars 2020 mission. "We're going to build a small instrument that will generate oxygen on Mars. It will be the prototype of a much larger 'factory' that will provide astronauts with oxygen at some point in the future," says Morten Bo Madsen, the head of the Mars group at the Niels Bohr Institute at the University of Copenhagen. The project is known at NASA as MOXIE (Mars OXygen In Situ resource...

    Billionaire biz baron Elon Musk has revealed a few more details about why SpaceX's latest attempt to land a rocket in one piece at sea had failed. The Register reported on the drama as it unfolded on Tuesday. Once again, Falcon 9 successfully launched the capsule payload to 'nauts on the International Space Station, only for the rocket to hit the "just read the instructions" deck hard on its shaky return to Earth.

    As the midsummer Sun beats down on the southern mountains of Mars, bringing daytime temperatures soaring up to a balmy 25ºC (77ºF), some of their slopes become darkened with long, rusty stains that may be the result of water seeping out from just below the surface. The image above, captured by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Feb. 20, shows mountain peaks within the 150-km (93-mile) -wide Hale Crater. Made from data acquired in visible and near infrared wavelengths the long stains are very evident, running down steep slopes below the rocky cliffs. These dark lines, called...
  • Ice on Mars: Mars has belts of glaciers consisting of frozen water

    Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the ground, but radar measurements show that underneath the dust there are glaciers composed of frozen water. New studies have now calculated the size of the glaciers and thus the amount of water in the glaciers.

    Radar images previously revealed thousands of buried glacier-like formations in the planet’s northern and southern hemispheres. That data has now been incorporated into computer models of ice flow to determine the glaciers’ size and hence how much water they contain. “We have looked at radar measurements spanning 10 years back in time to see how thick the ice is and how it behaves. A glacier is, after all, a big chunk of ice and it flows and gets a form that tells us something about how soft it is. We then compared this with how glaciers on Earth behave and...

    Despite a declaration from President Barack Obama that the moon is not a planned destination for American astronauts, senior NASA engineers have quietly begun reconsidering using it as a staging point for an eventual mission to Mars.William Gerstenmaier, the chief of human exploration for NASA, does not see the president's plan of a direct, 900-day mission to the red planet as achievable. Instead, Gerstenmaier believes large amounts of ice at the lunar poles may provide an important reservoir of oxygen and hydrogen fuel to propel rockets and spaceships across the 40 million miles of space to Mars."If propellant was available...

    Currently studying the “Pahrump Hills” region at the base of Mount Sharp in the center of Gale Crater, this new view snapped by Curiosity on March 18 shows a work site Curiosity’s mission scientists call “Garden City.” This area is interesting as it shows two-tone mineral veins protruding from the surrounding rock. The tough mineral veins were formed in Mars’ ancient wet past and they are sticking out of the rock up to 6 centimeters (2.5 inches) high. This means that the veins formed within the rock and the softer surrounding bedrock has since eroded away. When comparing the geology...

    Mars Atmosphere and Volatile EvolutioN Mission (MAVEN) of the National Aeronautics and Space Administration (NASA) has uncovered two new mysteries in the atmosphere of Mars. The probe, which has been orbiting the Red Planet since last year has noticed a weird high-altitude dust cloud and an aurora show in the atmosphere of the planet. According to reports, the dazzling aurora light show was much lower in the Martian atmosphere than scientists anticipated. In addition, scientists do not know about the origin of the dust cloud. According to the space agency, the dust cloud had extended from about 150 kilometers to...

    Explanation: It was late in the northern martian spring when the HiRISE camera onboard the Mars Reconnaissance Orbiter spied this local denizen. Tracking across the flat, dust-covered Amazonis Planitia in 2012, the core of this whirling dust devil is about 140 meters in diameter. Lofting dust into the thin martian atmosphere, its plume reaches about 20 kilometers above the surface. Common to this region of Mars, dust devils occur as the surface is heated by the Sun, generating warm, rising air currents that begin to rotate. Tangential wind speeds of up to 110 kilometers per hour are reported for dust...

    Explanation: It is not every day that such an interesting cloud photobombs your image. The original plan was to photograph a rare angular conjunction of Mars and Venus that occurred a week and a half ago, with the added bonus of a crescent Moon and the International Space Station (ISS) both passing nearby. Unfortunately, on Madeira Island, Portugal, this event was clouded out. During the next day, however, a spectacular lenticular cloud appeared before sunset, so the industrious astrophotographer quickly formulated a new plan. A close look at the resulting image reveals the Moon visible toward the left of the...

    Like Earth, the interior of Mars has undergone a process known as differentiation. This is where a planet, due to its physical or chemical compositions, forms into layers, with denser materials concentrated at the center and less dense materials closer to the surface. In Mars’ case, this translates to a core that is between 1700 and 1850 km (1050 – 1150 mi) in radius and composed primarily of iron, nickel and sulfur. This core is surrounded by a silicate mantle that clearly experienced tectonic and volcanic activity in the past, but which now appears to be dormant. Besides silicon and...

    Explanation: What is creating unusual plumes on Mars? No one is sure. Noted and confirmed by a global contingent of amateur astronomers on photos of the red planet in March 2012, possibly similar plumes have now been found on archived images as far back as 1997. Since the plumes reach 200 kilometers up, they seem too high to be related to wind-blown surface dust. Since one plume lasted for eleven days, it seemed too long lasting to be related to aurora. Amateur astronomers will surely continue to monitor the terminator and edge regions of Mars for new high plumes, and...

    A mysterious haze high above Mars has left scientists scratching their heads. The vast plume was initially spotted by amateur astronomers in 2012, and appeared twice before vanishing. Scientists have now analysed the images and say that say the formation, stretching for more than 1,000km, is larger than any seen before. Writing in the journal Nature, the researchers believe the plume could be a large cloud or an exceptionally bright aurora. However, they are unsure how these could have formed in the thin upper reaches of the Martian atmosphere. Continue reading the main story “ Start Quote To begin with,...

    Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet. On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet. The plumes were seen rising to altitudes of over 250 km above the same region of Mars on both occasions. By comparison, similar features seen in the past have not exceeded 100 km. "At about 250 km, the division between the atmosphere and outer space is very thin, so the reported plumes are extremely unexpected," says Agustin Sanchez-Lavega of...

    Images taken by Europe's Mars Express spacecraft show a crater on the Red Planet that looks like a "happy face". Crater Galle contains parallel gullies on its southern rim, a possible sign of liquid water running on Mars' surface. Its interior has also been shaped by the action of wind and shows signs of "dust devil" tracks, which have removed the bright surface coating of dust. A US space agency (Nasa) orbiter has also sent back its first colour image after arriving at Mars on 11 March. The "face" in the European images was first pointed out in photos taken...

    Explanation: What caused these Martian rocks to be layered? The leading hypothesis is an ancient Martian lake that kept evaporating and refilling over 10 million years -- but has now remained dry and empty of water for billions of years. The featured image, taken last November by the robotic Curiosity rover, shows one-meter wide Whale Rock which is part of the Pahrump Hills outcrop at the base of Mount Sharp. Also evident in the image is cross-bedding -- rock with angled layers -- which were likely facilitated by waves of sand. Curiosity continues to find many layered rocks like this...

    NASA's Curiosity rover has been busy with its drill again, and analysis of the second sample of Martian rock is already turning up some unexpected conditions back when the red planet supported liquid water. Curiosity put its low-percussion-level drill into play for the first time last week, carving a chunk out of a site known as "Mojave 2" at the base of Mount Sharp, and feeding it in powder form into its Chemistry and Mineralogy (CheMin) instrument. Turns out, even though the analysis isn't finished yet, there are already signs of a surprising amount of jarosite, to a degree that...

    One of the main challenges NASA engineers face is the very low density of the Martian atmosphere. To be able to lift off in such a thin atmosphere, the blades of the Mars Helicopter have to spin much faster than here on Earth, a report by Discovery News explains. Even operating only a few minutes a day, NASA says the solar-powered helicopter could enormously accelerate the pace of scientific discovery on the planet. Some envision swarms of these inexpensively built, automated drones zipping daily over the Martian landscape, collecting geological and atmospheric data over a large area. Given the fast...

    Scientists have revealed the full technical details of their discovery of vast reservoirs of ice beneath the Martian surface. So much ice has been found in the polar regions that if it were to melt it would deluge the planet. The ice may stretch far underground to regions where it is warm, raising the possibility of warm caverns of meltwater in which scientists hesitantly speculate conditions could be suitable for life. But they caution that we may never know until we have rock and ice samples returned to Earth by an unmanned probe for analysis. Third time lucky William Boynton,...

    While asteroids residing in the inner solar system will pass quickly through such small fields, trans-Neptunian objects (TNOs) orbit the Sun much more slowly. For example, Pluto, at an approximate distance of 40 A.U. from the Sun, along with the object Eris, presently the largest of the TNOs, has an apparent motion of about 27 arc seconds per day – although for a half year, the Earth’s orbital motion slows and retrogrades Pluto’s apparent motion. The 27 arc seconds is approximately 1/60th the width of a full Moon. So, from one night to the next, TNOs can travel as much...

    Such an inflatable heat shield could help a spacecraft reach the high-altitude southern plains of Mars and other areas that would otherwise be inaccessible with existing technology. The experts note that rockets alone can't be used to land a large craft on Mars as can be done on the moon.... Parachutes also won't work for a large spacecraft needed to send humans to Mars, they add. Hence the inflatable rings, known as the Hypersonic Inflatable Aerodynamic Decelerator, which would be filled with nitrogen and covered with a thermal blanket. Once deployed for landing, the rings would sit atop the spacecraft,...

    Usually, all telemetry data is stored in the flash memory, so that when the rover powers down during the Martian night or reboots, the data remains stored — like when you turn off your digital camera, the photos remain saved to the camera’s flash card. Any data stored in the rover’s RAM, however, is lost as it shuts down. Flash memory may be great for storing data when the rover’s electronics are powered down, “but flash memory has a limitation on how many times you can read and write to it,” Callas told Discovery News. “It ‘wears out’ with use.”

    The premise of a ballistic capture: Instead of shooting for the location Mars will be in its orbit where the spacecraft will meet it, as is conventionally done with Hohmann transfers, a spacecraft is casually lobbed into a Mars-like orbit so that it flies ahead of the planet. Although launch and cruise costs remain the same, the big burn to slow down and hit the Martian bull's-eye—as in the Hohmann scenario—is done away with. For ballistic capture, the spacecraft cruises a bit slower than Mars itself as the planet runs its orbital lap around the sun. Mars eventually creeps up...

    Explanation: What's creating methane on Mars? Recent measurements from the robotic Curiosity rover currently rolling across Mars indicate a surprising 10-fold increase in atmospheric methane between measurements only months apart. Life is a major producer of methane on Earth, and so speculation is rampant that some sort of life -- possibly microbial life -- is creating methane beneath the surface of Mars. Other possibilities do exist, though, with a leading model being the sudden release of methane produced by the mixing of specific soil chemicals with underground water. Proposed origins of Martian methane are depicted in the featured illustration. The...

The findings made by Tomohiro and the international research team help to account for this. “The total inventory of “observable” current surface water (that mostly occurs as polar ice, ~10E6 km3) is more than one order magnitude smaller than the estimated volume of ancient surface water (~10E7 to 10E8 km3) that is thought to have covered the northern lowlands,” said Tomohiro. “The lack of water at the surface today was problematic for advocates of...

    Unexplained methane spikes suggest bacteria is living on the red planet Nasa scientists in California have revealed evidence for life on Mars They say methane spikes on the planet could be produced by bacteria And, at the moment, there is no better explanation for the spikes The signs were spotted briefly occurring by one of Curiosity's instruments Life is the chief producer of methane on Earth, although there are many non-biological processes that can also generate the gas But no such process could be ruled out during tests - suggesting there may be bacteria living on or under the surface...

    NASA's picture-perfect Orion launch to Mars was all the rage last week. Praise was heaped upon key NASA contractors Boeing (NYSE: BA ) and Lockheed Martin (NYSE: LMT ) -- and deservedly so. Between Orion's success, and the companies' announcement that their United Launch Alliance joint venture will develope a "next-generation liquid oxygen/hydrocarbon first stage" rocket to power launches to near-Earth orbit, Boeing and Lockheed are on a hot streak. But amid all the hullaballoo at ULA, you might have forgotten there's another space launch company that is building even more innovative products. Its name is SpaceX. It goes up,...

    Asteroid sourced hydrogen and oxygen will literally and figuratively fuel expansion of the space economy by providing a locally sourced fuel resource that will change how industry operates in space. While existing satellites cannot be refueled directly today, space tugs fueled by asteroids that are currently being developed, will maneuver Geostationary satellites into their assigned orbit. Thus, keeping them operating and generating revenue far beyond their current life expectancy. Water from asteroids can also be used for a plethora of other applications beyond fuels in space. It can be consumed, used as a radiation shield for humans during deep space...

    The textured area, located in the Athabasca region of Mars, measures in at around 1.2 miles wide, and is plopped right in the middle of a landscape of smooth lava flows. Considering the lava flow landscape, NASA scientists theorize that volcanoes played a part in the creation of the wart, offering up the possibility that lava flowed beneath a mound of ice and pushed it up — the unique texture being created when the ice melted.

    If the new space race was like the movies, this week would be The Empires Strikes Back. On Friday, after a weather delay, Nasa launched a very cool space capsule, in what at first blush looked like another Apollo mission. It rose on a massive rocket spewing superheated exhaust like some creature from a Peter Jackson movie. All went well just now – and given the expertise of engineers performing what was essentially an update of a 1970s Apollo mission, that much was expected: a four-seat capsule called Orion will detach any minute now, and soar around the Earth twice,...

    [I love the idea of going to Mars. We humans are explorers and pioneers. But if government does this, it will be just too costly, like the Apollo Moon program. Elon Musk of the private SpaceX company already has put rockets into space and he wants to send settlers to Mars, including himself. So since governments have screwed up this planet, how about reserving Mars for free people?!] Breaking: NASA is sending humans to Mars NASA has announced that a test launch of their Orion space capsule will take place on Thursday, in the first step of a mission that...

    A meteorite from Mars that landed on Earth in 2011 contains a carbon compound that is biological in origin. (snip) "We cannot and do not want to entirely exclude the possibility that organic carbon within Tissint may be of abiotic origin," Lin wrote, meaning the carbon maybe physical in origin rather than organic -- devoid of life.7 "It could be possible that the organic carbon originated from impacts of carbonaceous chondrite meteorites. However, it is not easy to conceive bywhich processes chondritic carbon could have been selectively extracted from the impacting carbonaceous chondrites, selectively removed from the soil and later...

    If you're planning to go to the 2014 Annual Fall Meeting of the American Physical Society in Illinois this Saturday, you might be in for a bit of a surprise with the final talk of the day. Because that's when plasma physicist Dr John Brandenburg will present his theory that an ancient civilisation on Mars was wiped out by a nuclear attack from another alien race. In his bizarre theory, Dr Brandenburg says ancient Martians known as Cydonians and Utopians were massacred in the attack - and evidence of the genocide can still be seen today. Back in 2011 the...

    For many space-faring nations, ambitions for Mars run broad and deep. Now, add China to the list of countries with Mars in their sights. News reports from China disclosed that country is considering a future Mars rover mission, with a potential 2020 launch date. Additionally came other hints that China may be looking to develop a next-generation heavy-lift launch system. This new project, while early in development, reveals how Chinese aspirations are growing rapidly. Human space flight successes have been followed by recent lunar mission successes of the Yutu lunar rover and the Chang’e-5 T1 test of a sample return...
