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...

Chaos Causes Beauty

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...

Scars Of Mars Early History

ESA Ripped apart by tectonic forces, Hebes Chasma and its neighboring network of canyons bear the scars of the Red Planet’s early history. ESA’s Mars Express has flown over this region of Mars on numerous occasions, but this new eight-image mosaic reveals Hebes Chasma in full and in greater detail than ever. Hebes Chasma is an enclosed, almost 8 km-deep trough stretching 315 km in an east–west direction and 125 km from north to south at its widest point. It sits about 300 km...

Fly Through Valles Marineris On Mars

ESA [ Watch The Video Fly-through movie of Hebes Chasma ] Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning color movie from ESA's Mars Express. Valles Marineris is not just the largest canyon on Mars, but at 4000 km long, 200 km wide and 10 km deep it is the largest in the entire Solar System. The movie focuses on an enclosed 8 km-deep trough in the northern most part of Valles Marineris, called Hebes Chasma. The movie glides over impact...

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...

Underground Explosions Responsible For Pits Inside Twin Craters On Mars
2013-04-11 11:32:25

ESA Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA´s Mars Express on 4 January. The ℠twin´ craters are in the Thaumasia Planum region, a large plateau that lies immediately to the south of Valles Marineris, the largest canyon in the Solar System. The northernmost (right) large crater in this scene was officially given the name Arima in early 2012, but the southernmost...

Mars Express And HRSCview Turns Everyone Into Explorers
2013-03-25 19:03:05

Lee Rannals for redOrbit.com — Your Universe Online Our planet has been mapped out and explored for the most part, but there are plenty of other planets out there waiting to be discovered, and the European Space Agency's (ESA) Mars Express has provided the means to do so. Mars Express has spent the last ten years snapping images of the Red Planet, and a web interface featuring an archive of these images offers up the chance to explore any region on Mars through the eyes of the...

Surface Features of Mars

Alan McStravick for redOrbit.com - Your Universe Online Scientists will never know who first looked to the heavens and noticed the pale pink, barely visible orb that graces our early morning skies. We do know the Greeks named the red planet Ares in honor of their god of war. It wasn´t until the Romans came on the scene and renamed this celestial sphere for their own god of war, however, that we came to know our heavenly neighbor as Mars. Over the years, Mars has received a lot of...

Ancient Mars Caverns May Have Captured Flood Water
2012-12-05 16:24:33

Lee Rannals for redOrbit.com — Your Universe Online Researchers have found evidence that ancient caverns on Mars may have captured enormous flood waters some 2 billion years ago. Planetary Science Institute researchers studied the terminal regions of the Hebrus Valles, which is an outflow channel that extends about 155 miles downstream from two zones of surface collapse. The Martian outflow channels are made up of some of the largest known channels in the solar system....
