Mars : (1) the Roman god of war (2) the planet fourth in order from the sun and conspicuous for its red color — Webster See also Oxford, OneLook, Free Dictionary, Wiktionary, InfoPlease, Word Reference, Urban Dictionary
Mars is the fourth planet from the Sun in the Solar System. Named after the Roman god of war, Mars, it is often described as the “Red Planet” as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. — Wikipedia

"I would doubt many people in Rockford know Ingersoll is manufacturing these components," Mike Reese, director of sales for Ingersoll Machine Tools, told VOA. But "these" aren't just any components
- Preparations Continue Before Driving into 'Perseverance Valley' May 28, 2017 7:45 amPasadena CA (JPL) May 26, 2017 Opportunity is at the top of Perseverance Valley on the rim of Endeavour crater. The plan before proceeding down the valley is to survey the valley from the top and to perform a walk-about survey above the spillway. On Sol 4733 (May 17, 2017), the robotic arm was used to point the Microscopic Imager (MI) up at the sky for some long overdue sky flat calibration images, and in support
- Schiaparelli landing investigation completed May 28, 2017 7:45 amParis (ESA) May 25, 2017 The inquiry into the crash-landing of the ExoMars Schiaparelli module has concluded that conflicting information in the onboard computer caused the descent sequence to end prematurely. The Schiaparelli entry, descent and landing demonstrator module separated from its mothership, the Trace Gas Orbiter, as planned on 16 October last year, and coasted towards Mars for three days. Much o
- NASA Scientist Parlays Experience to Build Ocean Worlds Instrument May 28, 2017 7:45 amGreenbelt MD (SPX) May 24, 2017 An instrument originally developed to search for organic molecules on Mars is being repurposed to potentially hunt for life on a handful of moons in the outer solar system that appear to host oceans, geysers and vents of ice volcanoes. Will Brinckerhoff, a NASA scientist at the Goddard Space Flight Center in Greenbelt, Maryland, helped build a mass spectrometer for the European Space Agenc
- History of Titan's Landscape Resembles Mars's, not Earth's May 28, 2017 7:45 amBoston MA (SPX) May 19, 2017 The environment on Titan, Saturn's largest moon, may seem surprisingly familiar: Clouds condense and rain down on the surface, feeding rivers that flow into oceans and lakes. Outside of Earth, Titan is the only other planetary body in the solar system with actively flowing rivers, though they're fed by liquid methane instead of water. Long ago, Mars also hosted rivers, which scoured valleys acro
- HI-SEAS Mission V Mars simulation marks midway point May 28, 2017 7:45 amHonolulu HI (SPX) May 22, 2017 After four months of living in a Mars-like environment, the six HI-SEAS Mission V crewmembers have hit the halfway mark. They have learned to deal with challenges such as a 20-minute communications delay, gearing up in hazmat suits to explore the geologic features of the landing site and cooking with dehydrated food. "The midpoint is an interesting time in the mission," observed crewmember
- Scientists describe origins of topographic relief on Titan May 28, 2017 7:45 amNew York NY (SPX) May 19, 2017 Fluid erosion has carved river networks in at least three bodies in our solar system in the form of water on Earth and Mars and liquid hydrocarbons on Titan. A new report in Science examines the global drainage patterns of these worlds to shed light on their geologic past. Titan's landscapes look similar to Earth's in many ways. But is this similarity only superficial? Scientists from CUNY
- Deciphering the fluid floorplan of a planet May 28, 2017 7:45 amWashington DC (SPX) May 19, 2017 An assessment of ancient drainage systems on Earth, Mars and Titan provides new insights into the topography-generating mechanisms on planetary bodies. The results illustrate the diverse geological processes affecting these bodies and their river networks. The movement of liquids such as water across a planetary surface forms rivers, signatures of which can be seen even long after the liqu
- Mars Rover Opportunity Begins Study of Valley's Origin May 28, 2017 7:45 amPasadena CA (JPL) May 16, 2017 NASA's Mars Exploration Rover Opportunity has reached the main destination of its current two-year extended mission - an ancient fluid-carved valley incised on the inner slope of a vast crater's rim. As the rover approached the upper end of "Perseverance Valley" in early May, images from its cameras began showing parts of the area in greater resolution than what can be seen in images taken
- How hard did it rain on Mars May 28, 2017 7:45 amWashington DC (SPX) May 17, 2017 Heavy rain on Mars reshaped the planet's impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect o
- Ancient Mars impacts created tornado-like winds that scoured surface May 28, 2017 7:45 amProvidence RI (SPX) May 12, 2017 In looking at NASA images of Mars a few years ago, Brown University geologist Peter Schultz noticed sets of strange bright streaks emanating from a few large-impact craters on the planet's surface. The streaks are odd in that they extend much farther from the craters than normal ejecta patterns, and they are only visible in thermal infrared images taken during the Martian night. Using geol
- Opportunity Reaches 'Perseverance Valley' May 28, 2017 7:45 amPasadena CA (JPL) May 12, 2017 Opportunity has arrived at the top of "Perseverance Valley" on the rim of Endeavour Crater. The next step on Sol 4720 (May 4, 2017), was a short approach of 39 feet (12 meters) to the northern end of the "spillway" that overtops into Perseverance. From this vantage point, the rover has been engaged in multiple-sol collection of extensive Panoramic Camera (Pancam) panoramas all around the r
- Seasonal Flows in Valles Marineris May 28, 2017 7:45 amPasadena CA (JPL) May 08, 2017 Recurring slope lineae (RSL) are seasonal flows on warm slopes, and are especially common in central and eastern Valles Marineris, as seen in this observation by NASA's Mars Reconnaissance Orbiter (MRO). This image covers a large area full of interesting features, but the enhanced color closeup highlight some of the RSL. Here, the RSL are active on east-facing slopes, extending from boulde
- NASA Rover Curiosity Samples Active Linear Dune on Mars May 28, 2017 7:45 amPasadena CA (JPL) May 05, 2017 As it drives uphill from a band of rippled sand dunes, NASA's Curiosity Mars rover is toting a fistful of dark sand for onboard analysis that will complete the rover's investigation of those dunes. From early February to early April, the rover examined four sites near a linear dune for comparison with what it found in late 2015 and early 2016 during its investigation of crescent-shaped dun
