Lava Floods Mars Ancient Plains
2014-03-06 09:30:21

ESA Two distinct volcanic eruptions have flooded this area of Daedalia Planum with lava, flowing around an elevated fragment of ancient terrain. The images were acquired by ESA’s Mars Express on 28 November 2013 towards the eastern boundary of the gigantic Tharsis Montes volcanic region, where the largest volcanoes on Mars are found. The lava flows seen in this image come from Arsia Mons, the southernmost volcano in the Tharsis complex, which lies around 1000 km to the northwest of...

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...

King Of Canyons - Mars Valles Marineris
2012-10-23 05:13:19

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....

Image 1 - Mars Express Helps Map History Of Martian Volcanic History
2012-04-27 04:03:23

Lee Rannals for RedOrbit.com Mars Express has helped to unveil volcanic history of the Red Planet, providing more insight as to what lies underneath our celestial neighbor. The spacecraft has been floating above Mars, mapping out the planet, for five years, during which it has helped researchers find that lava grew denser over time, and that the thickness of the planet's rigid outer layers varies across the Tharsis region. The measurements were taken while Mars Express was orbiting...

Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars. These results were presented on March 4, 2010 at the 41st Lunar and Planetary Science Conference by Jacob Bleacher at NASA's Goddard Space Flight Center, Greenbelt, Md. Whether channels on Mars were formed by water or by lava has been debated for years, and the outcome is thought to influence the likelihood...

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...

Picture a ball. It's an ordinary ball in every way except that it is roughly 4,300 miles in diameter and is moving through the cold of space some 35 million miles from Earth, and hurtling around the sun in just less than two Earth years. This is Mars. After a first glance at the Martian surface, one may quickly notice two striking global-scale features. The first is the three-mile elevation difference between the northern lowlands and southern highlands, known as the Crustal Dichotomy, which...

The High Resolution Stereo Camera on board ESA's Mars Express imaged the Eumenides Dorsum mountains on the Red Planet. Eumenides Dorsum lies at approximately 2° south and 206° east. The images, taken on 26 December 2007, have a ground resolution of about 13 m/pixel. They cover an area of about 12 000 square km. The mountains are located to the west of the Tharsis Region, and form part of the Medusae-Fossae Region, which is most likely covered by a blanket of volcanic ash. The region...

Olympus Mons -- Olympus Mons is the tallest mountain in the solar system, at 25 km. Located on Mars, and officially called by its Latin name Olympus Mons. It is named for the mountain on Earth. Olympus Mons is an apparently extinct shield volcano, the result of highly fluid magma flowing out of volcanic vents over a long period of time, and is much wider than it is tall; the average slope of Olympus Mons' flanks is very gradual. The Hawaiian islands are an example of similar shield...
