  • Two new NASA missions
  • will try to discover what transformed Mars
  • There are signs that in the distant past, billions of years ago, Mars was a much more inviting place. Martian terrain is carved with channels that resemble dry riverbeds
  • ...3 more annotations...
  • The Mars Science Laboratory (MSL) mission features Curiosity, the largest and most advanced rover ever sent to the Red Planet
  • The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, scheduled to launch in late 2013, will orbit Mars and is devoted to understanding the Red Planet's upper atmosphere
  • help determine what caused the Martian atmosphere—and water— to be lost to space, making the climate increasingly inhospitable for life.

  • Amoeba-Sized Insect Is Missing Some Pieces
  • microscopic analysis of the fairy wasp (Megaphragma mymaripenne
  • 200 micrometers in length is one of the world's smallest animals
  • ...3 more annotations...
  • shown compared to a paramecium and amoeba above
  • When the scientist compared the neurons of adult and pupae fairy wasps, he discovered that more than 95% of adult neurons lack a nucleus
  • suggest that while a complete set of neurons is needed to grow, far less are required to live

  • A 70-million-year-old nest of the dinosaur Protoceratops andrewsi has been found with evidence that 15 juveniles were once inside it
  • finding multiple juveniles in the same dino nest is quite rare
  • analyzed the dinosaur remains along with the nest, which measured about 2.3 feet in diameter and was round and bowl-shaped
  • ...6 more annotations...
  • found at Djadochta Formation, Tugrikinshire, Mongolia,
  • researchers conclude that the 15 dinosaurs all show juvenile characteristics
  • At least 10 of the 15 fossil sets are complete
  • nest further implies that parental care was provided.
  • Mongolia was, at the time, a place with a variety of theropod dinosaurs, some of whom likely ate babies such as these
  • The most obvious of these, found in the same deposits, is the (in)famous Velociraptor

  • An instrument on NASA's Mars rover Curiosity can check for any water that might be bound into shallow underground minerals along the rover's path.
  • The Dynamic Albedo of Neutrons instrument, or DAN, will scout for underground clues to a depth of about 20 inches (50 centimeters).
  • Russian Federal Space Agency contributed it to NASA as part of a broad collaboration
  • ...7 more annotations...
  • In active mode, it is sensitive enough to detect water content as low as one-tenth of one percent in the ground beneath the rover.
  • With pulses lasting about one microsecond and repeated as frequently as 10 times per second
  • The generator will be able to emit a total of about 10 million pulses during the mission, with about 10 million neutrons at each pulse.
  • DAN can tell us how the shallow subsurface may differ from what the rover sees at the surface. None of our other instruments have the ability to do this
  • will provide the ability to detect hydrated minerals or water ice in the shallow subsurface
  • will also provide a ground-truth calibration for the measurements that the gamma-ray and neutron detectors on Odyssey have made and continue to make
  • enhancing the value of that global data set

  • must liftoff by Dec. 18 at the latest, when the launch window to Mars closes for another 26 months
  • is by far the most advanced robotic emissary sent to the surface of another celestial body
  • MSL will operate for a minimum of one Martian year, equivalent to 687 days on earth.
  • ...4 more annotations...
  • Curiosity’s purpose is to search for evidence of habitats that could ever have supported microbial life on Mars
  • determine whether the ingredients of life exist on Mars today in the form of organic molecules
  • The nuclear power source will significantly enhance the driving range, scientific capability and working lifetime of the six wheeled rover compared to other solar powered landed surface explorers
  • The science payload weighs ten times more than any prior Mars rover mission.
