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...

Idaho, Mars Canyons Share Similarities: Carved By Massive Megafloods
2014-01-17 09:15:38

redOrbit Staff & Wire Reports - Your Universe Online The shared geological features found in U-shaped bedrock canyons both in south-central Idaho and on the surface of Mars are likely the result of massive floods, according to research appearing in the journal Proceedings of the National Academy of Sciences (PNAS). California Institute of Technology (Caltech) geology professor Michael P. Lamb and his colleagues explain that while there have been other explanations for the formation...

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...

King Of Canyons - Mars Valles Marineris

April Flowers for redOrbit.com - Your Universe Online One of the most awe-inspiring sights on the planet Earth is the Grand Canyon. The Colorado River has cut through 2 billion years of geologic history, carving out a canyon that is 277 miles long and up to 18 miles wide. However, next to Valles Marineris on Mars, the Grand Canyon is a mere scratch in the ground. Valles Marineris stretches over 4000 kilometers in length and is 200 kilometers wide, with a maximum depth of 10 kilometers....

Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars"”a chasm larger than the Grand Canyon and a series of spiral troughs"”solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars. In a pair of papers to be published in the journal Nature on May 27, Jack Holt and Isaac Smith of The University of Texas at Austin's Institute for Geophysics and their colleagues describe how they used radar...

The U.S. space agency says its Mars Reconnaissance Orbiter has found evidence that liquid water remained on Mars far longer than previously theorized. The National Aeronautics and Space Administration spacecraft has observed hydrated silica, or opal, spread across large regions of Mars. That, scientists said, suggests liquid water was on the planet's surface as recently as 2 billion years ago. "This is an exciting discovery because it extends the time range for liquid water on Mars, and...

NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars. This discovery suggests that liquid water remained on the planet's surface a billion years later than scientists believed, and it played an important role in shaping the planet's surface and possibly hosting life. Researchers examining data from the orbiter's Compact Reconnaissance Imaging Spectrometer for Mars have found evidence of hydrated silica, commonly known as opal. The...

Parts of ancient Mars may have been wet for a billion years longer than scientists previously thought, a new study of images of the red planet's surface suggests. Along with Earth and the other inner planets of our solar system, Mars formed about 4.5 billion years ago. Scientists have long known that flowing water formed many of the features seen on Mars today, but previous studies suggested that water runoff from precipitation had ceased after the first billion years of Mars'...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show Coprates Chasma, a major trough in the Valles Marineris canyon system. The HRSC obtained these images during orbit 449 with a ground resolution of approximately 48 metres per pixel. The scenes show the region containing the sections of Coprates Chasma and Coprates Catena, over an area centred at about 13.5º South and 300º East, roughly in...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
