mars (8)Mars had oxygen-rich atmosphere 4,000 million years ago
Oxford, UK (SPX) Jun 21, 2013 – Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4000 million years ago – well before the rise of atmospheric oxygen on Earth 2500m years ago. Scientists from Oxford University investigated the compositions of Martian meteorites found on Earth and data from NASA’s ‘Spirit’ rover that examined surface rocks in t … more

Mars Water-Ice Clouds Are Key to Odd Thermal Rhythm
Pasadena CA (JPL) Jun 14, 2013 – Researchers using NASA’s Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice. “We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight,” said Armin Kleinboehl of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., who is the lead author of … more

UH Astrobiologists Find Martian Clay Contains Chemical Implicated in the Origin of Life
Manoa HI (SPX) Jun 13, 2013 – Researchers from the University of Hawaii at Manoa NASA Astrobiology Institute (UHNAI) have discovered high concentrations of boron in a Martian meteorite. When present in its oxidized form (borate), boron may have played a key role in the formation of RNA, one of the building blocks for life. The work was published on June 6 in PLOS One. The Antarctic Search for Meteorites team found the … more

Aging Mars rover makes new water discoveries
Washington (AFP) June 7, 2013 – Scientists on Friday called NASA’s Opportunity rover gimpy and arthritic, but hailed its new discoveries about early water on Mars made almost 10 years after it was launched toward the Red Planet. The unmanned solar-powered vehicle has just analyzed what may be its oldest rock ever, known as Esperance 6. It contains evidence that potentially life-supporting water once flowed in abundance, le … more

The floodwaters of Mars
Paris (ESA) Jun 07, 2013 – Dramatic flood events carved this impressive channel system on Mars covering 1.55 million square kilometres, shown here in a stunning new mosaic from ESA’s Mars Express. The mosaic, which features the spectacular Kasei Valles, comprises 67 images taken with the spacecraft’s high-resolution stereo camera and is released during the week of the 10th anniversary of the spacecraft’s launch to t … more
