The article presents a study which examines the fresh meteorite crater across the planet mars for signs of frozen water. Researchers found out that the impact of metallic and stony objects show traces of subsurface ice. Researchers presumed that atmospheric water vapor gradually pass into high-latitude Martian soil and frozen between soil particles forming into a half-soil and a half-ice mixture.

The article reports that an impact crater buried under ice on Mars has returned to view. The feature appears as a lone hill rising out of an eroding slope. Shane Byrne of the Lunar and Planetary Laboratory at the University of Arizona believes the mound is a result of ice underneath eroding slower than the surroundings. The mound was discovered by the U.S. National Aeronautics and Space Administration's (NASA) Mars Reconnaissance Orbiter.

The article discusses three studies that have reinforced scientists' hypothesis that the difference in Mars' northern and southern terrain was caused by a large asteroid. One study used cartography to reveal a possible asteroid collision site, and two other studies used computer simulations to reveal a hypothesized impact crater. The need for future analysis of Martian rock samples is also mentioned.

The article reports on findings by the U.S. National Aeronautics and Space Administration's Mars Exploration Rover, Spirit. Spirit found silica near a plateau in the Gusev Crater on the planet Mars. The mini-thermal emission spectrometer on the rover found that the soil contains 90% amorphous silica. Silica, on Earth, is dissolved in rocks by hot water and then precipitated out near the surface when cooler water rises and this shows that there must have been water on Mars.

The article announces that a Martian crater has been named after Charles F. "Chick" Capen by International Astronomical Union. The article states that Capen is a Lowell Observatory astronomer who mentored a generation of Mars observers. According to the article, the 45-mile crater on Mars is near Sinus Meridiani at 6.6° north, 345.7° west.

This article focuses on Nicholson's Crater located at the southern edge of Mars' Amazonis Planitia. Large impact craters always have mountainous peaks at their centers. At the center of the 62-mile wide Nicholson's Crater, a 2.2-mile-high mountain rises nearly to the crater's rim. But there's something odd about Nicholson's central mountain. It forms the apex of a bulge that nearly spans the crater and covers much of its floor.

The article offers information on a virtual reality story on the Mars Gale crater by the newspaper "Los Angeles Times."

The article presents information on the National Aeronautics and Space Administration's (NASA) of the U.S. whose rover landed inside Gale Crater on Mars with fully equipped chemistry laboratories. It informs that the landing was flawless and stunning and the information about its first movement, arm unfurlings, atmospheric sniffings and dirt scoopings has been received by NASA.

The article reports on two studies regarding the climate characteristics of planet Mars which indicate that Mars was once wet. It notes that Mars has compositional features altered by liquid water in the exposed walls of its crater. Minerals formed from those dissolved species after millennia of weathering processes which could be matched to minerals found on Mars are also examined.
