High-Silica “Halos” Indicate Mars Was Quite Wet in the Past

NASA JPL May 30, 2017 Pale “halos” around fractures in bedrock analyzed by NASA’s Curiosity Mars rover contain copious silica, indicating that ancient Mars had liquid water for a long time. “The concentration of silica is very high at the centerlines of these halos,” said Jens Frydenvang, a rover-team scientist at Los Alamos National Laboratory in New Mexico, and the ...

New Theory Can Predict Global Dust Storms on Mars

NASA October 5, 2016 This graphic indicates a similarity between 2016 (dark blue line) and five past years in which Mars has experienced global dust storms (orange lines and band), compared to years with no global dust storm (blue-green lines and band). The horizontal scale is time-of-year on Mars. ______________________________________ Global dust storms on Mars could soon become more predictable ... Read More »

Gullies on Mars Probably Not Formed by Water

NASA JPL July 29, 2016 New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal more details about Mars’ recent geologic processes. Scientists use the term “gully” for features ... Read More »

Glass Deposits Detected on Mars

NASA JPL June 8, 2015 NASA’s Mars Reconnaissance Orbiter (MRO) has detected deposits of glass within impact craters on Mars. Though formed in the searing heat of a violent impact, such deposits might provide a delicate window into the possibility of past life on the Red Planet. During the past few years, research has shown evidence about past life has ... Read More »

Possible Supervolcano Caldera on Mars

ESA May 21, 2015 At first glance, the region covered by this latest Mars Express image release appears to be pockmarked with impact craters. But the largest structure among them may hold a rather explosive secret: it could be remains of an ancient supervolcano. The images presented here were taken by the high-resolution stereo camera on ESA’s Mars Express on ... Read More »

What is Causing the Mysterious Martian Plumes?

ESA February 16, 2015 Plumes seen reaching high above the surface of Mars are causing a stir among scientists studying the atmosphere on the Red Planet. On two separate occasions in March and April 2012, amateur astronomers reported definite plume-like features developing on the planet. The plumes were seen rising to altitudes of over 250 km above the same region ... Read More »

Mars Spacecraft Prepares for Orbit Insertion

NASA JPL September 17, 2014 NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles (711 million kilometers). Flight Controllers at Lockheed Martin Space Systems in Littleton, Colorado, will be responsible for the health and safety of the spacecraft throughout the process. ... Read More »

Curiosity Rover Finds Large Iron Meteorite on Mars

NASA July 15, 2014 This rock encountered by NASA’s Curiosity Mars rover is an iron meteorite called “Lebanon,” similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity.  Lebanon is about 2 yards or 2 meters wide (left to right, from this angle). The smaller piece in the foreground is ... Read More »

Mars Slammed by Big Meteor Impact

NASA JPL May 22, 2014 Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA’s Mars Reconnaissance Orbiter. The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in ... Read More »
