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
2013-03-08 05:54:03

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...

WASHINGTON, March 7, 2013 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has provided images allowing scientists for the first time to create a 3-D reconstruction of ancient water channels below the Martian surface. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) The spacecraft took numerous images during the past few years that showed channels attributed to catastrophic flooding in the last 500 million years. Mars during this period had been considered...

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

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...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) aboard ESA's Mars Express spacecraft, show a large depression called Iani Chaos and the upper reaches of a large outflow channel called Ares Vallis. Image strips were taken in October 2004, during three orbits from a 350-kilometre altitude, with a resolution of 15 metres per pixel. The strips have then been matched to a mosaic that covers an area from 17.5º western longitude to 3º...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the outlet channel of the Uzboi Vallis system into Crater Holden on Mars. The HRSC obtained these images during orbit 511 with a ground resolution of approximately 45 metres per pixel. The scenes show the region of Noachis Terra, over an area centred at about 26º South and 325º East. The valley of Uzboi Vallis begins in the region of Argyre...
