Opportunity Rover Sidelined

cheap canada goose uk The Opportunity rover recently surpassed the five year mark on Mars. And what did she get as a birthday present? A thorough canada goose jacket outlet uk zapping by a charged particle, perhaps a cosmic ray, which has sidelined the rover for the past canada goose uk site several days. stood down for a few sols as a result of a PMA (Panoramic Mast Assembly) error, said Scott Maxwell, one of the rover drivers for canada goose outlet in vancouver the two Mars Exploration Rovers, canada goose sale uk Opportunity and Spirit. turned out to be due to an SEU (Single Event Upset), as reported by the on board motor controller. An SEU happens when a charged particle whizzes through a transistor on the rover and flips a bit somewhere inside. the motor controllers can detect and report these events, so that the rover can safely stop, Maxwell told Universe Today. have good reason to hope that Opportunity PMA is undamaged and that she be back on the road shortly. The PMA is the canada goose outlet online store rover and head; it is the mast that holds the Panoramic Cameras, the Navigation Cameras and the Mini Thermal Emission Spectrometer. It would be canada goose vest outlet a critical canada goose victoria parka outlet blow to the mission to lose any or all of these instruments.

Canada Goose Online No images from the Pancams or Navcams have been downloaded buy canada goose uk to Earth for the past four days, since sol 1787 (today is sol 1791 for Opportunity.) Opportunity has been traversing quite quickly on her way to Endeavour Crater, about 12 kilometers (7 miles) away. That distance would match the total distance Opportunity traveled from 2004 canada goose outlet mall to mid 2008. Even at the 100 meter plus pace each sol, which canada goose outlet vancouver was able to do back in canada goose outlet hong kong December, the journey could take two years. canada goose parka mens Canada Goose Online

canadian goose jacket terrain canada goose outlet parka Opportunity is passing through is good driving terrain, said Maxwell, not quite a parking lot, but nothing she can handle. With the help of our satellite navigation canada goose outlet 80 off system (that is, the beautiful high resolution orbital images we get from MRO), we expect to continue making good time through this dune field canada goose outlet uk fake on the way to Endeavour. keep you posted on Opportunity status. canadian goose jacket

Spirit resumed canada goose outlet seattle driving Saturday, albeit just a short drive, after engineers performed diagnostic tests to determine the cause of behavior by the rover last week. On Spirit Sol 1800, the rover did not save information into its non volatile flash memory, so the information was lost when the rover next canada goose outlet trillium parka black powered down. She also seemed to be disoriented, and was not able to locate the sun canada goose outlet uk correctly.

Canada Goose sale may not find any data that will explain what happened on Sol 1800, but there no evidence that whatever happened then has recurred on subsequent sols, said Jacob Matijevic of the rover engineering team at NASA Jet Propulsion Laboratory, Pasadena. One possibility is that a cosmic ray hit could have temporarily put Spirit temporarily into a mode that disables use of the flash memory. Canada Goose sale

canada goose black friday sale Spirit drove only about 30 centimeters (1 foot) Saturday, during the 1,806th Martian sol. The rover team had commanded a longer drive, but Spirit canada goose outlet niagara falls stopped short after its right front wheel, which no longer turns, struck a partially buried rock. The rover drivers prepared commands Monday for the next drive in a slightly different direction to get around that rock. canada goose black friday sale

buy canada goose jacket Spirit drove down off canada goose coats uk Home Plate on Jan. 6, 2009.

The earlier discovery was interpreted as evidence canada goose outlet authentic left by a hot spring or steam vent environment. Examination with Spirit alpha particle X ray spectrometer confirmed silica at Stapledon. This indicates that the environment that deposited the silica was not limited to the location found earlier. buy canada goose jacket

Canada Goose Jackets Forgive my ignorance, but would this propensity to be bombarded by charged particles effect the development of microbial life on Mars? Does it only cause real harm to electronic equipment? I mean, if they can bullseye our rovers like this, would that mean they can, at least from time to time, rain down on the planet and neutralize vulnerable cells? Would it effect the chances of life on Mars at all? Is it a well established limitation for the current consideration of life on such planets with weak magnetic fields? Should I add another question mark? Canada Goose Jackets

Canada Goose online Tim, there are different feeds that talked of this issue. I would think microbial life would be have to buried canada goose outlet website legit deep in the ground of Mars. Your are correct when saying about raining down on canada goose outlet paypal our atmosphere.

Cromosomes can be damaged,destroyed but again, much research is required. You have probably heard when the Sun is erupting, there canada goose outlet toronto address is no spacewall allowed as charged particles canada goose outlet sale from the Sun can probably destroy enough cromosomes and vastly shorten lifespans of exposed humans in space. These UHECR,. the Sun canada goose outlet store quebec is not capable of producing them, perhaps not even a of the mill type 2 supernova but a supermassive star 50 100 times the Suns mass that collapses into a black hole most likely the cause of the gamma ray burst detected by gamma ray detector satillites and then rapidly notify the astronomers to see the visible light and use other orbiting types of other detectors. There are other incredibly violent events occuring in our universe that is capable of producing UHECR. canada goose factory outlet vancouver Our Earths atmosphere protects humans from the damaging effects of cosmic rays, but canada goose outlet store near me eventually, some will hit surface humans. An interesting article or series of articles has a theory that about.1% or 6,000,000 humans die yearly from cancer who had no history of cancer in their family nor in a cancerous canada goose outlet uk sale area or food. these are the canada goose jacket outlet very mysterious cancer cases with no Canada Goose online

Please read other feed having to do with LHC and others. My career ended as a Network Administrator, there are others on these feeds who are far more knowledgable about physics, space medicine, others in the professional science spectrum which is beyond my knowledge. buy canada goose jacket cheap

cheap Canada Goose In answer to your questions yes on all counts really; absolutely. There are microbes on Earth that are extremely hardy and resist radiation canada goose outlet store montreal damage well, but these are very few and far between. They are a sub category of the so called extremophiles canada goose outlet florida microbes that can take an absolute beating from various environments that would be toxic to most other life. An example of a different type of extremophile would be the bacteria that thrive around the thermal vents of the mid oceanic ridges they routinely deal with temperatures of greater than 400 deg. C, under extreme pressure, and deriving their energy from chemicals such as sulfides that are extremely toxic to almost all other life. cheap Canada Goose

Canada Goose Outlet Such microbes are rare, but the point is that It can be done, which would mean that it is possible maybe for life to deal with intense radiation blasts, but any life that evolved on the surface of Mars would have to adapt to such high doses or perish. Canada Goose Outlet
