oxia planum

The dust coverage is very low in this area and the surface is generally smooth. The region was chosen to include extensive, layered exposures rich in iron and magnesium phyllosilicates. The mission will be dispatched from Earth aboard a Russian Proton rocket, and the European-made rover will descend to the red planet in an entry pod under development led by Russia’s NPO Lavochkin. The fine sediments should also be ideal for the ExoMars drill – it aims to get to 2 metres depth. Follow Stephen Clark on Twitter: @StephenClark1. In October 2015, Oxia Planum was identified as one of the most compatible sites with the mission requirements – at that time with a 2018 launch date in mind – with a second option to be selected from Aram Dorsum and Mawrth Vallis. The rover will arrive at Mars in 2019 at the end of the red planet’s global dust storm season. NASA remains a junior partner, supplying navigation and tracking support, components for one of the rover’s chief organic analyzers, and radios for data relay. "With ExoMars we are on a quest to find biosignatures. Like Mawrth Vallis, the main scientific concern for this site relates to the lack of precise information regarding the geologic context and origin of the clay-bearing unit. First time offenders who are new to the site will be warned. Your email address is used only to let the recipient know who sent the email. They lie just north of the equator, with several hundred kilometres between them, in an area of the planet with many channels cutting through from the southern highlands to the northern lowlands. Thank you for taking your time to send in your valued opinion to Science X editors. There are few large impact craters in this region, but various outflow channels dissect the area as they converge toward Chryse Planitia. And wonder what I am. The clay outcrops spotted in Oxia were only revealed in the last few hundred million years, scientists said, as the top geologic layer eroded away. Observations from orbit show that the region exhibits layers of clay-rich minerals that were formed in wet conditions some four billion years ago, likely in a large body of standing water. A period of volcanic activity may have covered early clays and other aqueous deposits, offering preservation for biosignatures against the planet’s harsh radiation and oxidation environment, and have been exposed by erosion only within the last few hundred million years. The suite of mapping instruments aboard satellites in orbit around Mars has informed scientists about what awaits the rover at Oxia, but more detailed data is coming. Number of known asteroids reaches 1 million, Science X Daily and the Weekly Email Newsletter are free features that allow you to receive your favorite sci-tech news updates in your email inbox. I welcome all opinions, even those that strongly criticize my commentary. These probably represent the south-western expansion of the clay-rich deposits around Mawrth Vallis. But the schedule is very tight to have the rover ready for its launch window in May 2018, so scientists also identified potential landing sites if the mission’s launch is delayed to 2020, when Earth and Mars are aligned again to make the journey possible. The journey’s what I am. ESA ExoMars 2020 project scientist Remote identification with the Mars Express and Mars Reconnaissance Orbiter Infrared spectrometers shows the presence of clays and other minerals giving clues to its aqueous history. I must go out and find my home. As such, they preserve a rich record of geological history from the planet’s wetter past, billions of years ago. The test campaign for preparing the rover for Mars is in full swing. Oxia Planum contains one of the largest exposures of rocks on Mars that are around 3.9 billion years old and clay-rich, indicating that water once played a role here. The region is characterised by ancient highland cratered terrains that become increasingly eroded towards the highland-lowland boundary. The robot rover that Europe and Russia will send to Mars in 2020 will be targeted at a near-equatorial site on the Red Planet known as Oxia Planum. Neither your address nor the recipient's address will be used for any other purpose. It will relay its data to Earth through the Trace Gas Orbiter. The Oxia Palus quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. Mob: +31 6 27 65 87 70Email: jorge.vago@esa.int, Francois Spoto or, by European Space Agency. Oxia Planum is a plain located on Mars (near 18°16′30″N 335°22′05″E / 18.275°N 335.368°E ) that has been chosen as a preferred landing location for the ExoMars rover, with an elevation more than 3000 metres below the Martian mean. Medical Xpress covers all medical research advances and health news, Tech Xplore covers the latest engineering, electronics and technology advances, Science X Network offers the most comprehensive sci-tech news coverage on the web. The ExoMars Landing Site Selection Working Group has recommended Oxia Planum as the landing site for the ESA-Roscosmos rover and surface science platform that will launch to the Red Planet in 2020. A riveting new science fiction book by Robert Zimmerman that captures the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. The clay-rich rocks date to a time when Mars was habitable, and scientists suggest the overlying volcanic deposits could have preserved any biomarkers from ancient life from the destructive effects of radiation and oxidation. The ExoMars Landing Site Selection Working Group has recommended Oxia Planum as the landing site for the ESA-Roscosmos rover and surface science platform that will launch to the Red Planet in 2020. Recommendation for the Narrowing of ExoMars 2018 Landing Sites, Four candidate landing sites for ExoMars 2018, ExoMars 2018: landing site search to narrow, Landing site recommended for ExoMars 2018, Proposed landing sites for ExoMars 2018 mission. After that, I will ban you. Get weekly and/or daily updates delivered to your inbox. The site sits in an area of valley systems with the exposed rocks exhibiting different compositions, indicating a variety of deposition and wetting environments. Single, sinuous, deep valleys, hundreds of kilometres long, are present within and around the ellipse. Oxia Planum is at a boundary where many channels emptied into the lower plains, and those plains exhibit layers of clay-rich minerals that were … Since life as we know it on Earth requires liquid water, locations like these include many prime targets to search for clues that may help reveal the presence of past life on Mars. “Compared with landing site selection for previous missions, which relied primarily on the morphology of candidate sites alone, we are today in a much better position to understand the mineralogy of the various sites,” Vago said in a statement. Some lava material has resisted erosion until today, so the underlying materials may only have been exposed recently, initially protecting them from space radiation and later making them accessible to the rover and its analytical tools.

Then, the 120 x 19 km landing ellipses should not contain features that could endanger the landing, the deployment of the surface platform ramps for the rover to exit, and the subsequent driving of the rover.
