At first glance, Mars appears very different from Earth, but if you take a closer look, you'll discover that the Red Planet isn't all that different from our own.</p><h2>North Pole</h2><p>Our first stop, the North Pole. This ice cap is bigger than Texas, and is mostly covered in water ice and solid carbon dioxide, aka dry ice. Heading south, we'll visit Kasei Valles. It's a vast system of chasms five times longer and 10 times wider than the Grand Canyon, and scientists think it formed in a similar way. Billions of years ago, Mars was warmer, and covered with liquid water, which likely carved out valleys like this one.</p><h2>Mawrth Vallis</h2><p>Mawrth Vallis is another valley close by, but it looks very different from our previous spot, thanks to its multicolored layers of clay. These deposits probably formed over millennia as Mars shifted towards a colder, drier climate, and they could provide clues to the history of liquid water and possible ancient life on Mars.</p><h2>Bacquerel Crater</h2><p>The next stop is another place that may have been teeming with life long ago, Bacquerel Crater. It's filled with rocks made of sulfate similar to ones on Earth that form after water evaporates, which has led scientists to suspect that this crater may once have been a massive lake over 160 kilometers wide.</p><h2>Iani Chaos</h2><p>Next stop, Iani Chaos. Now, this is one type of terrain you won't find anywhere on Earth. It's a maze of rugged cliffs and pillar-like hills called mesas that extend for 200 kilometers, and since there is nothing like it on Earth, scientists aren't exactly sure how these unique features formed. Its larger neighbor, Hydraotes Chaos, probably formed in a similar mysterious way. It stretches 350 kilometers, the same distance as New York City to Boston.</p><h2>Valles Marineris</h2><p>West of Hydraotes, we find one Mars's greatest attractions, Valles Marineris. It's the largest canyon in the solar system, running the length of New York to Los Angeles, and plunging four times as deep as the Grand Canyon.</p><h2>Hebes Chasma</h2><p>Following the canyon's main channel north, we reach Hebes Chasma. It's tiny compared to Valles Marineris, but it's worth the trek for a glimpse of the chasma's prominent mesa.</p><h2>Olympus Mons</h2><p>And no trip to Mars would be complete without a visit to Olympus Mons, the tallest volcano in the solar system. It covers a region the size of Arizona. It's three times as tall as Mount Everest, and can comfortably fit all the volcanoes in Hawaii.</p><h2>Promethei Planum</h2><p>Moving south, we'll see Promethei Planum. It's a plane near the South Pole, covered in a sheet of ice nearly one and a half times as thick as the East Antarctic Ice Sheet.</p><h2>Rabe Crater</h2><p>Next, we'll swing around to Rabe Crater. It's covered in giant sand dunes 150 to 200 meters high, almost as tall as the Golden Gate Bridge.</p><h2>Neukum Crater</h2><p>Nearing the end of our tour is one of the oldest regions of Mars that dates back to at least 3.9 billion years ago, Neukum Crater. Scientists think this crater formed from a powerful impact early in Mars's history. In fact, you can still see pockmarks left by the crash.</p><h2>Galle Crater</h2><p>The last crater on our tour is formally named Galle Crater, but many call it Happy Face Crater for obvious reasons.</p><h2>South Pole</h2><p>Finally, we've reached our last stop, the South Pole. In 2018, scientists found evidence of a liquid lake beneath the ice, which could be filled with saltwater.</p><p>But while that's a promising discovery, we still have much to learn about this fascinating world, like whether life once existed in those ancient lakes, or if it still exists today, possibly somewhere underground. But perhaps the biggest question of all, could human life survive here? Maybe in the future, you won't have to imagine your Martian vacation.</p><p><em>Video credit: <a href="http://www.esa.int/ESA">ESA</a>/<a href="https://www.youtube.com/watch?v=uoblCdedNNM">Freie Universitat Berlin Planetary Sciences and Remote Sensing</a>/<a href="https://creativecommons.org/licenses/by-sa/3.0/igo/">CC BY-SA 3.0 IGO</a></em></p>

Okubo had seen thin layers of sediment in the basin that had piled up, one atop another, over about 500 million years.</p><p>Such layers form when groundwater gurgles to the surface, forming a shallow pool - and a potentially habitable oasis, says Okubo. Over time, grit blows into the water, which responds by pushing more upward to form another pool. More grit then blows in.

<keyword id="6360409" type="General" weightage="80" keywordseo="nasa" source="Orion">NASA</keyword>'s <keyword id="6474108" type="General" weightage="100" keywordseo="insight" source="Orion">InSight</keyword> lander has enabled scientists to measure the biggest quakes everwitnessed on Mars.<br /><br />On September 18, NASA's InSight lander celebrated its 1,000th Martian day, or sol, by measuring one of the biggest, longest-lasting marsquakes the mission has ever detected. The temblor is estimated to be of 4.2-magnitude and shook for nearly an hour-and-a-half, NASA said in a statement.<br /><br />This is the third major quake InSight has detected in a month: On August 25, the mission's seismometer detected two quakes of magnitudes 4.2 and 4.1.<br /><br />The previous record holder, which InSight measured in 2019, clocked in at magnitude 3.7 -- about five times less powerful than a 4.2-magnitude quake.<br /><br />Before NASA's InSight spacecraft touched down on Mars in 2018, the rovers and orbiters studying the <keyword id="6385434" type="General" weightage="20" keywordseo="red-planet" source="Orion">Red Planet</keyword> concentrated on its surface.<br /><br />The stationary lander's seismometer has changed that, revealing details about the planet's deep interior for the first time.<br /><br />The mission aims to study seismic waves to learn more about Mars' interior.<br /><br />While the teams are studying the September 18 quake, scientists have made some analysis of the August 25 quakes. According to them, the 4.2 magnitude event occurred about 8,500 kilometres from InSight. It's the most distant quake the lander has detected so far, NASA said.<br /><br />They also determined that the shaking occurred too far from where InSight had detected almost all of its previous large quakes -- <keyword id="12164988" type="General" weightage="20" keywordseo="cerberus-fossae" source="Orion">Cerberus Fossae</keyword> -- a region roughly 1,609 kilometres away where lava may have flowed within the last few million years.<br /><br />The scientists are working to pinpoint the source and which direction the seismic waves travelled.<br /><br />"One especially intriguing possibility is <keyword id="3478542" type="General" weightage="20" keywordseo="valles-marineris" source="Orion">Valles Marineris</keyword>, the epically long canyon system that scars the Martian equator. The approximate center of that canyon system is 9,700 kilometres from InSight,"NASA said.<br /><br />Further, the team also found that the August 25 quakes were different from each other. The magnitude 4.2 quake was dominated by slow, low-frequency vibrations, while fast, high-frequency vibrations characterised the magnitude 4.1 quake. The magnitude 4.1 quake was also much closer to the lander -- only about 925 kilometres away.<br /><br />"Despite their differences, the two August quakes do have something in common other than being big: Both occurred during the day, the windiest -- and, to a seismometer, noisiest -- time on Mars," NASA said.<br /><br />InSight's seismometer usually finds marsquakes at night, when the planet cools off and winds are low. But the signals from these quakes were large enough to rise above any noise caused by wind, the US space agency noted.<br /><br /><strong>SEE ALSO:<br /><a target="_blank" class="c-link c-message_attachment__title_link" href="https://www.businessinsider.in/business/ecommerce/news/amazon-diwali-sale-starts-from-october-4/articleshow/86475984.cms">Amazon Great Indian Festival: month-long festive sale kicks off from October 4 onwards</a><br /></strong><a target="_blank" class="c-link c-message_attachment__title_link" href="https://www.businessinsider.in/stock-market/news/aditya-birla-sun-life-amc-ipo-to-open-on-september-29-with-price-band-695-712-per-share/articleshow/86475370.cms"><strong>Aditya Birla Sun Life AMC’s ₹2768 crore IPO will open on September 29</strong></a>

It's unlikely Mars-bound spaceships could carry enough water, oxygen, and hydrogen for the entire journey there and back, so they would likely need to mine it on Mars.</p><div type="image" title="wavy sheet of ice on mars view from space" height="810" width="1080" msid="92557475" hostid="261" sizebytes="25322"></div><p>The Zhurong rover traveled nearly 2 kilometers (1.2 miles) before going into hibernation to save its energy through Mars's hyper-cold winter, according to state media.
