Lawrence LeBlond for redOrbit.com - Your Universe Online Evidence that the surface of the Red Planet had a watery past is being challenged by scientists after studies of rock samples from an old atom bomb test site in the Pacific. The new finding suggests that Mars was not as warm and wet as many scientists have predicted. A team of scientists from Caltech have made the theory after their research of rock formations on Mururoa Atoll in French Polynesia. They found these formations...

What locations would you go see if you had a chance to visit the surface of Mars? This is the question that researchers have been pondering for several years and now the landing sites have been narrowed down to four choices from an original list of 60 sites, according to several sources. After a two-year delay, the next robotic rover to roam the surface of Mars is set to launch in November, The rover Curiosity, part of the Mars Science Laboratory Program, is the size of a small car and will...

Clay deposits found in one of the oldest riverbed-like channels on Mars shows some unusual signatures that may shed light on the history of water -- and possibly life -- on the red planet. Observations made by an instrument onboard NASA's Mars Reconnaissance Orbiter (MRO), currently circling the planet, already have shown substantial clay deposits that formed about 4 billion years ago in two regions of Mars, Mawrth Vallis and Nili Fossae, that indicate that water was more...

WASHINGTON -- Two studies based on data from NASA's Mars Reconnaissance Orbiter have revealed that the Red Planet once hosted vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life. One study, published in the July 17 issue of Nature, shows that vast regions of the ancient highlands of Mars, which cover about half the planet, contain clay minerals, which can form only in the presence of water. Volcanic lavas buried the clay-rich regions...

During its first week of observations from low orbit, NASA's newest Mars spacecraft is already revealing new clues about both recent and ancient environments on the red planet. Scientists hope the Mars Reconnaissance Orbiter will answer questions about the history and distribution of Mars' water by combining data from the orbiter's high-resolution camera, imaging spectrometer, context camera, ground-penetrating radar, atmospheric sounder, global color camera, radio and accelerometers....

ESA -- Substantial quantities of liquid water must have been stably present in the early history of Mars. The findings of OMEGA, on board ESA's Mars Express, have implications on the climatic history of the planet and the question of its 'habitability' at some point in its history. These conclusions were drawn thanks to data on Martian surface minerals obtained by OMEGA (Observatoire pour la Mineralogy, l'Eau, les Glaces et l'Activit©), the visible and infrared mapping spectrometer on...
