  • A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life
  • This water could be some of the oldest on the planet and may even contain life
  • the similarity between the rocks that trapped it and those on Mars raises the hope that comparable life-sustaining water could lie buried beneath the red planet's surface
  • ...13 more annotations...
  • Researchers
  • analysed water pouring out of boreholes from a mine 2.4 kilometres beneath Ontario, Canada
  • found that the water is rich in dissolved gases like hydrogen, methane and different forms – called isotopes – of noble gases such as helium, neon, argon and xenon
  • there is as much hydrogen in the water as around hydrothermal vents in the deep ocean, many of which teem with microscopic life
  • The hydrogen and methane come from the interaction between the rock and water, as well as natural radioactive elements in the rock reacting with the water
  • These gases could provide energy for microbes that may not have been exposed to the sun for billions of years.
  • The crystalline rocks surrounding the water are thought to be around 2.7 billion years old. But no-one thought the water could be the same age, until now
  • Using ground-breaking techniques
  • researchers show that the fluid is at least 1.5 billion years old, but could be significantly older.
  • interconnected fluid system in the deep Canadian crystalline basement that is billions of years old, and capable of supporting life
  • Before this finding, the only water of this age was found trapped in tiny bubbles in rock and is incapable of supporting life
  • the water found in the Canadian mine pours from the rock at a rate of nearly two litres per minute
  • don't yet know if the underground system in Canada sustains life

  • The team operating NASA's Curiosity Mars rover has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.
  • "Cumberland," lies about nine feet (2.75 meters) west of the rock where Curiosity's drill first touched Martian stone in February
  • Both rocks are flat, with pale veins and a bumpy surface. They are embedded in a layer of rock on the floor of a shallow depression called "Yellowknife Bay.
  • ...6 more annotations...
  • This second drilling is intended to confirm results from the first drilling, which indicated the chemistry of the first powdered sample from John Klein was much less oxidizing than that of a soil sample the rover scooped up before it began drilling.
  • Cumberland and John Klein are very similar, Cumberland appears to have more of the erosion-resistant granules that cause the surface bumps
  • concretions, or clumps of minerals, which formed when water soaked the rock long ago
  • Mission engineers
  • recently finished upgrading Curiosity's operating software following a four-week break
  • rover continued monitoring the Martian atmosphere during the break, but the team did not send any new commands

  • Developed by researchers at the Korea Advanced Institute of Science and Technology, the camera creates a heatmap-like view of machinery (or anything else
  • 30 digital microphones and a high-res camera pick up on what's making noise, and an image shows the different levels of noise, organized by a color gradient
  • Blue means a little noise, while red is the most extreme level.
  • ...1 more annotation...
  • not the first sound camera, but at about 4 pounds, it's one of the most portable
