Curiosity Rover Archives
canada goose uk outlet Ever since it landed on the Red Planet in 2012, the Curiosity rover has showed no signs of slowing down! For the past six years, it has ventured across the Gale Crater, scaled Mount Sharp, and taken numerous drill samples. And in the process, it has found evidence that liquid water (and possibly even life) once existed on the Martian surface. canada goose uk outlet
Canada Goose Jackets It has also taken many breathtaking pictures that have catalogued its progress. Last month (on Aug. 9th), the rover took another 360 degree panoramic photo of its location. Though they can begin quite suddenly, these storms typically stay contained to a local area and last only about a few weeks. canada goose outlet reviews However, on occasion, Martian dust storms can grow to become global phenomena, covering the entire planet.

canada goose clearance sale One such storm began back in May, starting in the Arabia Terra region canada goose outlet and then spreading to become a planet wide dust canada goose outlet store uk storm within a canada goose outlet parka matter of weeks. This storm caused the skies over the Perseverance Valley, where the canada goose outlet online uk Opportunity rover is stationed, to become darkened, forcing the rover into hibernation mode. And while no word has been heard from the rover, NASA recently indicated that the dust storm will dissipate in a matter of weeks. canada goose clearance sale
uk canada goose The update was posted by NASA Mars Exploration Program, which oversees operations for the Opportunity and Curiosity rovers, as well as NASA three Mars orbiters (Mars Odyssey, MRO, and MAVEN) and the Insight lander (which will land on Mars in 109 days). According to NASA, the storm is beginning to end, though it may be weeks or canada goose outlet months before the skies are clear enough for Opportunity to exit its hibernation mode. uk canada goose

cheap canada goose uk As noted, dust storms occur on Mars when the southern hemisphere experiences summer, which coincides with the planet being closer to the Sun in its elliptical orbit. Due to increased temperatures, dust particles are lifted higher into the atmosphere, creating more wind. The resulting wind kicks up yet more dust, creating a feedback loop that NASA scientists are still trying to understand. cheap canada goose uk
Since the southern polar region is pointed towards the Sun in the summer, carbon dioxide frozen in the polar cap evaporates. This has the effect of thickening the atmosphere and increasing the surface pressure, which enhances the process by helping suspend dust particles in the air. In some cases, the dust clouds can reach up to 60 km (40 mi) or canada goose outlet canada more in elevation.
Planet wide dust storms are a relatively rare occurrence on Mars, taking place every three to four Martian years (the equivalent of approximately 6 to 8 Earth years). Such storms have been viewed many times in the past by missions like Mariner 9 (1971), Viking I (1971) and the Mars Global canada goose black friday sale Surveyor (2001). In 2007, a similar storm took place that darkened the skies over where Opportunity was stationed which led to two weeks of minimal operations and no communications.
Canada Goose Outlet While smaller and less intense the storm that took place back in canada goose outlet shop 2007, the current storm intensified canada goose outlet uk sale to the point where it led to a level of atmospheric opacity that is much worse than the 2007 storm. In effect, the amount of dust in the atmosphere created a state of perpetual night over the rover’s location in Perseverance Valley, which forced canada goose outlet jackets the rover goose outlet canada science team to canada goose outlet toronto factory suspend operations.

This is due to the fact that Opportunity unlike the Curiosity rover, which runs on nuclear powered canada goose outlet store battery relies on solar panels to keep its batteries charged. canada goose outlet online But beyond suspending operations, the prolonged dust storm also means that the rover might not be to keep its energy intensive survival heaters running which protect its batteries from the extreme cold of Mars’ atmosphere.
Canada Goose sale Luckily, NASA scientists who have been observing the global event indicated that, as of last Monday (July 23rd), more dust was falling out of the planet thin air than was being raised into it. This means that the global weather event has reached its decay phase, where dust raising events either become confined to smaller areas or stop altogether. The Curiosity rover also noted a decline in dust above its position in the Gale Crater on the other side of the planet. Canada Goose sale
uk canada goose outlet This is certainly good new for the Opportunity rover, though scientists expect that it will still be a few weeks or months before its solar panels can draw power again and communications can be reestablished. The last time communications took place with the rover was on June 10th, but if there one thing the Opportunity rover is known for, it endurance! uk canada goose outlet
When the rover first landed on Mars on January 25th, 2004, its mission was only expected to last ninety Martian days (sols), which is the equivalent of about 92.5 Earth days. However, as of the writing of this article, the rover has endured for 14 years and 195 days, effectively exceeding its operational lifespan 55 times over. So if any rover can survive this enduring dust storm, its Opportunity!
In the meantime, multiple NASA missions are actively monitoring the storm in support of canada goose outlet uk Opportunity and to learn more about the mechanics of Martian storms. By learning more about what causes these storms, and how smaller ones can merge to form global events, future robotic missions, crewed missions and (quite possibly) Martian colonists will be better prepared to deal with them.
canada goose clearance The weather patterns on Mars are rather fascinating, owing to their particular similarities and differences with those of Earth. For one, the Red Planet experiences dust storms that are not dissimilar to storms that happen regularly here on Earth. Due to the lower atmospheric pressure, these storms are much less powerful than hurricanes on Earth, but can grow so large that they cover half the planet. canada goose clearance
Recently, the ESA Mars Express orbiter captured images of the towering cloud front of a dust storm located close to Mars northern polar region. This storm, which began in April 2018, took place in the region known as Utopia Planitia, close to the ice cap at the Martian North Pole. It is one of several that have been observed on Mars in recent months, one which is the most severe to take place in years.
Canada Goose Online The images (shown above and below) were created using data acquired by the Mars Express High Resolution Stereo Camera (HRSC). The camera system is operated canada goose outlet sale by the German Aerospace Center (DLR), and managed to capture images of this storm canada goose jacket outlet front which would prove to be the harbinger of the Martian storm season on April 3rd, 2018, during its 18,039th orbit of Mars.
