Curiosity findings from Yellowknife Bay sharpen CO2 paradox of ancient Mars climate
Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet’s surface. Yet, the ancient sun was about one-third less warm and climate modelers struggle to produce scenarios … Continue reading

Mars had lakes & streams long after early wet era
Lakes and snowmelt-fed streams on Mars formed much later than previously thought possible, according to new findings using data primarily from NASA’s Mars Reconnaissance Orbiter. The recently discovered lakes and streams appeared roughly a billion years after a well-documented, earlier … Continue reading

Evaporating lakes made veins in Mars rocks
Mineral veins found in Mars’s Gale Crater were formed by the evaporation of ancient Martian lakes, a new study has shown. [The study was published in the journal Meteoritics & Planetary Science.] The research, by Mars Science Laboratory Participating Scientists … Continue reading
HiRISE: Einstein and Mars
In February 1917, Albert Einstein wrote in a letter: “It is a pity that we do not live on Mars and just observe man’s nasty antics by telescope.” We do have a telescope at Mars, but we use it to … Continue reading
Rise and fall of Martian lakes
There is a wealth of evidence, collected over the past few decades, suggesting liquid water was abundant in the early history of Mars. However, the size, evolution, and duration of standing bodies of water such as lakes on Mars’ surface … Continue reading

Lakes in Noctis Labyrinthus: ancient habitable environments?
Groundwater circulation beneath a massive tectonic rift zone located along the flanks of some the Solar System’s largest volcanic plateaus resulted in the formation more than 3 billion years ago of some the deepest basins on Mars, according to a … Continue reading
Free access to Gale Crater lakes Science papers
Two of the papers published in Science (October 9, 2015) relating to the discovery of ancient lakes in Gale Crater have been posted online, with the full texts available without charge. The papers are titled: “Deposition, exhumation, and paleoclimate of … Continue reading

Ancient lakes indicate wet paleoclimate at Gale
A new study from the team behind NASA’s Mars Science Laboratory/Curiosity has confirmed that Mars was once, billions of years ago, capable of storing water in lakes over an extended period of time. Using data from the Curiosity rover, the … Continue reading

Did lake-effect storms make Martian snowbelts?
Numerous places on Mars show erosion by precipitation, whether as rainfall or runoff from melting snow. The precipitation could have come from a thicker atmosphere or a temporary boost in atmospheric temperature and density following a large impact. Both scenarios … Continue reading
