    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,...

    Britain's Beagle 2 lander has finally been spotted, 12 years after it went missing while trying to land on the surface of Mars History books will need to be rewritten after scientists announced today that Beagle 2 has been finally been found on Mars, 12 years after it vanished without trace. The beleaguered spacecraft, which has become a byword for mission failure, was spotted by scientists operating the HiRise camera on NASA’s Mars Reconnaissance Orbiter (MRO). It was discovered just 5km from its original touchdown site in the Isidis Planitia basin. And it appears that just one faulty motor was...

    Time to stop remarking about how unearthly cold it is outside because on Thursday, Mars was actually warmer than many parts of the U.S. The daytime high in the red planet's Gale Crater, as recorded by NASA's curiosity Rover, was 17.6 degrees F - a whopping 11 degrees warmer than the 6-degree high in Green Bay, Wisconsin. Temperatures in fourteen states from Washington to Maine reported temperatures colder than Mars, as a brutal blast of Arctic air sweeps the country.

    This isn’t the first time spacecraft have detected new craters on Mars. In fact, the largest new crater discovered was half the length of a football field. And so far, researchers have turned up more than 400 new craters on the surface of Mars. The Mars Context Camera has completely imaged the entire surface of Mars at least once during its 7-year mission. And with multiple passes, planetary scientists are starting to build up a picture of how the dynamic the surface of Mars can really be.
  • The Dark Energy Survey Begins to Reveal Previously Unknown Trans-Neptunian Objects

    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...
  • NASA studies inflatable heat shield for Mars landing

    01/03/2015 4:22:37 PM PST · by BenLurkin · 13 replies
    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,...
  • Mars Rover Opportunity Suffers Worrying Bouts of 'Amnesia'

    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...

    Basically, there is a gap between what is thought to have existed in the past, and what is observed today in the form of water ice. 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...

    NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill. "This temporary increase in methane -- sharply up and then back down -- tells us there must be some relatively localized source," said Sushil Atreya of the University of Michigan, Ann Arbor, a member of the Curiosity rover science team. "There are many possible sources, biological or non-biological, such as interaction of water and rock."

    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,...

    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...
