New Study Finds That Lava Carved The Giant Valleys Of Mars
2014-05-13 07:17:31

April Flowers for redOrbit.com - Your Universe Online In 1877, Giovanni Schiaparelli of Italy first described what he called "canali" on the surface of Mars. These straight landforms on the Martian equatorial region form a conspicuous net-like system of deep gorges called the Noctis Labyrinthus, which is clearly visible. Noctis Labyrinthus leads into the even larger Valles Marineris canyon, which is 2500 miles long,  125 miles wide and 4 miles deep. Together, these two systems would span...

ESA Beautiful streamlined islands and narrow gorges were carved by fast-flowing water pounding through a small, plateau region near the southeastern margin of the vast Vallis Marineris canyon system. Images captured on 7 December 2013 by ESA’s Mars Express show the central portion of Osuga Valles, which has a total length of 164 km. It is some 170 km south of Eos Chaos, which lies in the far eastern section of Valles Marineris. Osuga Valles is an outflow channel that emanates from...

Mars Express Shows Of The Red Planet's Flood History
2013-06-06 13:39:33

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency (ESA) said that a new image taken by its Mars Express orbiter shows off flood events that took place on the Red Planet. The flooding events that took place at Kasei Valles carved out an impressive channel system on Mars that stretches nearly 580,000 square miles. The mosaic taken by Mars Express comprises of 67 images taken with the spacecraft's high-resolution stereo camera. Kasei Valles is one of...

3-D Image Of Buried Mars Flood Channels

April Flowers for redOrbit.com - Your Universe Online For the first time ever, new maps of the subsurface of Mars show buried channels below the surface of the planet. These channels suggest evidence of flooding on a planet that has been considered by scientists to be cold and dry for the last 2.5 billion years. The young channels are located in Elysium Planitia, an expanse of plains along the equator. This region is also the youngest volcanic region on Mars. Understanding the scale and...

Mars Express Orbiter Snaps Image Of River-Like Formation On Surface Below
2013-01-18 16:04:26

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Mars Express has offered up a high-resolution photo of a river-like structure on Mars. The spacecraft used its high-resolution stereo camera last year to snap an image of Reull Vallis on the Red Planet. Reull Vallis is a river-like structure believed to have formed when running water flowed in the distant martian past. The ancient river bed cuts a steep-sided channel through the Promethei...

Image 1 - 'Honeycombs' And Hexacopters Help Tell Story Of Mars
2012-02-18 06:22:14

In a rough-and-tumble wonderland of plunging canyons and towering buttes, some of the still-raw bluffs are lined with soaring, six-sided stone columns so orderly and trim, they could almost pass as relics of a colossal temple. The secret of how these columns, packed in edge to edge, formed en masse from a sea of molten rock is encrypted in details as tiny as the cracks running across their faces. To add to this mystery's allure, decoding it might do more than reveal the life story of some...

Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. The research, by a team from Imperial College London and University College London (UCL), suggests that during the Hesperian Epoch, approximately 3 billion years ago, Mars had lakes made of melted ice, each around 20km wide, along parts...

The Mars Express High Resolution Stereo Camera imaged a region close to Ma'adim Vallis, one of the largest canyons on Mars, finding craters, lava flows and tectonic features.After Valles Marineris, Ma'adim Vallis is one of the largest canyons on Mars. The region, lying south-east of Ma'adim Vallis, was imaged on 24 December 2008. The pictures are centered at about 29°S and 182°E and have a ground resolution of 15 m/pixel. Ma'adim Vallis is located between the volcanic region of...

When Mars was still young, more than four billion years ago, a large asteroid sailed out of the sky and slammed into an area known today as western Arabia Terra. The object hit hard enough that it blasted a basin at least 280 kilometers (175 miles) wide. The basin is now named Aram Chaos. As many millions of years passed, into this yawning bowl drifted sediments of many kinds - wind-blown dust, sand, and volcanic ash. The Martian climate was wetter then, so the crater-filling debris became...
