  • might
  • During the first 12 weeks after Curiosity landed
  • researchers analyzed data from more than 20 atmospheric events with at least one characteristic of a whirlwind recorded
  • ...10 more annotations...
  • can include a brief dip in air pressure, a change in wind direction, a change in wind speed, a rise in air temperature or a dip in ultraviolet light reaching the rover
  • Two of the events included all five characteristics.
  • dust-devil tracks and shadows have been seen from orbit, but those visual clues have not been seen in Gale Crater
  • possibility is that vortex whirlwinds arise at Gale without lifting as much dust as they do elsewhere
  • The rover is just north of a mountain called Mount Sharp
  • air movement up and down the mountain's slope governed wind direction, dominant winds generally would be north-south
  • east-west winds appear to predominate. The rim of Gale Crater may be a factor
  • If we don't see a change in wind patterns as Curiosity heads up the slope of Mount Sharp—that would be a surprise."
  • may be seeing more of the wind blowing along the depression in between the two slopes, rather than up and down the slope of Mount Sharp
  • The atmosphere provides a level of shielding, and so charged-particle radiation is less when the atmosphere is thicker. Overall, Mars' atmosphere reduces the radiation dose compared to what we saw during the flight to Mars

shared by Mars Base on 15 Nov 12 - No Cached
  • NASA is marking two milestones in the search for planets like Earth; the successful completion of the Kepler Space Telescope's three-and-a-half-year prime mission and the beginning of an extended mission that could last as long as four years.
  • identify more than 2,300 planet candidates and confirm more than 100 planets
  • hundreds of Earth-size planet candidates have been found
  • ...14 more annotations...
  • Highlights from the prime mission
  • confirmed the discovery of the first planetary system with more than one planet transiting the same star
  • the discovery of the first unquestionably rocky planet outside the solar system
  • 1.4 times the size of Earth
  • confirmed the existence of a world with a double sunset
  • discoveries of six additional worlds orbiting double stars further demonstrated planets can form and persist in the environs of a double-star system
  • first planet in a habitable zone
  • December 2011
  • September 2011
  • February 2012
  • transiting planet candidates
  • total of 2,321
  • Recently
  • The joint effort of amateur astronomers and scientists led to the first reported case of a planet orbiting a double star

  • pictures haven't turned up any dust devils.
  • With Thanksgiving coming up we've been preparing a few days worth of commands to send up to the rover to keep it busy while people here take some much needed time off
