"We knew there was ice below the surface at high latitudes of Mars, but we find that it extends far closer to the equator than you would think, based on Mars' climate today," said Shane...
Earth Sciences |Opportunity’s two-year exploration of Victoria Crater – a half-mile wide and 250 feet deep – yielded a treasury of information about the planet’s geologic history and supported previous findings indic...
Physics and Astronomy |What is less known is how much water occupied the red planet and what happened to it during its geological march to the present. Mostly, evidence has pointed to a period when clay-rich minerals were f...
Physics and Astronomy |The STONE-6 experiment tested whether sedimentary rock samples could withstand the extreme conditions during a descent though the Earth’s atmosphere where temperatures reached at least 1700 degrees Ce...
Physics and Astronomy |About four billion years ago, there were lakes on Mars which may have been fed by short-lived rivers that were, in turn, fed by precipitation. These lakes filled craters that were formed by the impact...
Physics and Astronomy |Dr Gerhard Schmidt from the University of Mainz, Germany, has calculated that about 160 metallic asteroids of about 20 kilometres in diameter would be sufficient to provide the concentrations of these...
Physics and Astronomy |One of the proposed explanations--a massive asteroid impact--now has strong support from computer simulations carried out by two groups of researchers. Planetary scientists at the University of Califo...
