A digital terrain model of Valles Marineris. (ESA/DLR/FU Berlin (G. Neukum), CC BY-SA 3.0 IGO) ---------------------------------------------------------------------------- A vast system of canyons that dramatically scars the face of Mars could be harboring reserves of hidden water. An unusually high quantity of hydrogen has been detected in the heart of the 4,000 kilometers (2,485 miles) of canyons known as Valles Marineris, nicknamed the Grand Canyon of Mars. We know this thanks to new data from the ESA-Roscosmos ExoMars Trace Gas Orbiter's FREND instrument. The finding suggests that, at depths up to a meter (three feet) below the surface, the soil in the...

About 87 million miles (140 million kilometers) above the Grand Canyon, an even larger, grander abyss cuts through the gut of the Red Planet. Known as Valles Marineris, this system of deep, vast canyons runs more than 2,500 miles (4,000 km) along the Martian equator, spanning nearly a quarter of the planet's circumference. This gash in the bedrock of Mars is nearly 10 times as long as Earth's Grand Canyon and three times deeper, making it the single largest canyon in the solar system — and, according to ongoing research from the University of Arizona (UA) in Tucson, one of...

Explanation: As telescopes around planet Earth watch, Mars is growing brighter in night skies, approaching its 2020 opposition on October 13. Mars looks like it's watching too in this view of the Red Planet from September 22. Mars' disk is already near its maximum apparent size for earthbound telescopes, less than 1/80th the apparent diameter of a Full Moon. The seasonally shrinking south polar cap is at the bottom and hazy northern clouds are at the top. A circular, dark albedo feature, Solis Lacus (Lake of the Sun), is just below and left of disk center. Surrounded by a light...

The Mars Reconnaissance Orbiter (MRO) delivers once again! Using its advanced imaging instrument, the High Resolution Imaging Experiment (HiRISE) camera, the orbiter captured a breathtaking image (shown below) of the plains north of Juventae Chasma. This region constitutes the southwestern part of Valles Marineris, the gigantic canyon system that runs along the Martian equator. The image was originally taken in July of 2007 by the HiRISE camera and showcases three distinct types of terrain. In the top half of the image, this includes plains with craters and sinuous ridge features. These features are of particular interest since they could be...

Researchers from the US Smithsonian Institution and King’s College London argue for preserving seven-eighths of the solar system as official 'space wildernesses.' This regulation would protect planets, moons and other bodies from unchecked mining and other types of industrial exploitation. But its core aim would be to ensure that humankind's expansion into our star system is undertaken manageably to avoid a future where all the resources are gone. … It will be challenging to decide which aspects of our star system should be protected from the space mining industry, the researchers wrote in their paper. However, areas that might merit...

"Meridani Planum is located on the equator due east of the giant canyons of Valles Marineris. It is a subsection region inside Arabia Terra, the largest of the transition zones between the lower elevation vast plains of the northern hemisphere and the higher elevation crater southern highlands."

Explanation: Mars will look good in Earth's skies over the next few days -- but not this good. To get a view this amazing, a spacecraft had to actually visit the red planet. Running across the image center, though, is one the largest canyons in the Solar System. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris...
