Mars' Moons Vs. Earth’s Moon
2013-02-18 09:19:35

Rayshell Clapper for redOrbit.com — Your Universe Online Earth has one moon, and it is considerably larger than Pluto. In fact, the relative size of Earth´s moon is quite massive compared to the moons of other planets. We have a fascination with our moon on many levels. But what if Earth had two moons as Mars does? According to NASA, unlike Earth´s moon, Mars moons are two of the smallest in the entire solar system. Mars moons also have proper names: Phobos and...

Iapetus Ice Avalanches Explain Landslides Elsewhere

Lee Rannals for redOrbit.com - Your Universe Online Researchers from Washington University in St. Louis, Missouri have found that giant ice avalanches on Saturn's moon Iapetus could provide clues to slippage in other places in the Solar System. Kelsi Singer, graduate student in Earth and planetary sciences in Arts & Sciences at the university, says that landslides take place everywhere in the Solar System, but Iapetus has more giant landslides than any celestial body in our...

Lee Rannals for redOrbit.com The European Space Agency's Mars Express has found evidence that underground water used to exist during the first billion years of Mars' existence. ESA's Mars Express and NASA's Mars Reconnaissance Orbiter zoomed in on craters in part of the region of the ancient southern highlands called Tyrrhena Terra. Scientists were able to identify 175 sites bearing minerals formed in the presence of water by focusing in on the chemistry of rocks embedded in the...

Lee Rannals for redOrbit.com Researchers from the University of Colorado in Boulder have cataloged over 635,000 Martian craters. The research team just recently finished up counting, outlining and cataloging the 635,000 impact craters on Mars that are roughly a half-mile in diameter. “This database is a giant tool that will be helpful in scores of future Mars studies ranging from age-dating and erosion to planetary habitability and to other applications we have not even thought...

Written on the moon's weary face are the damages it has endured for the past 4-1/2 billion years. From impact craters to the dark plains of maria left behind by volcanic eruptions, the scars are all that remain to tell the tale of what happened to the moon. But they only hint at the processes that once acted"”and act today"”to shape the surface.To get more insight into those processes, Meg Rosenburg and her colleagues at the California Institute of Technology, Pasadena, Calif. put...

A digital terrain model generated from a stereo pair of images provides this synthesized, oblique view of a portion of the wall terraces of Mojave Crater in the Xanthe Terra region of Mars. This view, in which the vertical dimension is exaggerated three-fold compared with horizontal dimensions, shows the ponding of material backed up behind massive wall-terrace blocks of bedrock. Hundreds of impact craters on Mars have similarly ponded features with pitted surfaces. These "pitted ponds" are...

Deforestation in the Democratic Republic of the Congo has unveiled what could be one of the largest impact craters discovered over the past 10 years, according to a noted Italian scientist. University of Padova scholar Giovanni Monegato, who presented his findings during the recent Lunar and Planetary Science Conference in Texas, was one of the researchers who spotted the 30-mile ring using satellite imagery. He states that the geologic feature, located near the Unia River, became...

The High Resolution Stereo Camera on ESA's Mars Express orbiter has obtained images of Hephaestus Fossae, a region on Mars dotted with craters and channel systems. Hephaestus Fossae lies at about 21° North and 126° East on the Red Planet. Named after the Greek god of fire, it extends for more than 600 km on the western flank of Elysium Mons in the Utopia Planitia region. Obtained on 28 December 2007, the images have a ground resolution of about 16 m/pixel. They show that the region...

As the fragments of shattered comet 73P/Schwassmann Wachmann 3 glide harmlessly past Earth this month in full view of backyard telescopes, onlookers can't help but wonder, what if a comet like that didn't miss, but actually hit our planet? For the answer to that question, we look to the Sahara desert. In a remote windswept area named Aorounga, in Chad, there are three craters in a row, each about 10 km in diameter. "We believe this is a 'crater chain' formed by the impact of a fragmented...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...
