Read moreWindy, Wet and Wild: Victoria Crater Unveils More of Mars’ Geologic Past
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 | Read moreLife on Mars? Brown-led research team says elusive mineral bolsters chances
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...

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 | Read moreEvidence for rain on Mars?
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 | Read moreMeteorites from inner Solar System match up to Earth's plantinum standard
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 | Read moreEvidence of massive asteroid impact on Mars supported by computer simulations
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...
Physics and Astronomy | Read moreLaser fluorescence could find life on Mars
The researchers' proposed instrumentation could operate on any Mars lander or rover, they say, such as the current Phoenix mission or NASA's Mars Science Laboratory scheduled for launch in 2...
