  • 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

  • While

  • The spacecraft remained in communications at all scheduled communication windows on Wednesday, but it did not send recorded data, only current status information.
  • status information revealed that the computer had not switched to the usual daily "sleep" mode when planned
  • Diagnostic work in a testing simulation at JPL indicates the situation involved corrupted memory at an A-side memory location used for addressing memory files
  • Scientific investigations by the rover were suspended Wednesday
  • Resumption of science investigations is anticipated within several days

  • The rover team chose a similar rock, "Cumberland," as the second drilling target to provide a check for the findings at John Klein
  • Scientists are analyzing laboratory-instrument results from portions of the Cumberland sample
  • One new capability being used is to drive away while still holding rock powder in Curiosity's sample-handling device to supply additional material to instruments later if desired by the science team
  • For the drill
  • at Cumberland, steps that each took a day or more at John Klein could be combined into a single day's sequence of commands
  • used the experience and lessons from our first drilling campaign, as well as new cached sample capabilities, to do the second drill
  • far more efficiently
  • In addition,
  • increased use of the rover's autonomous self-protection. This allowed more activities to be strung together before the ground team had to check in on the rover
  • The science team has chosen three targets for brief observations before Curiosity leaves the Glenelg area: the boundary between bedrock areas of mudstone and sandstone, a layered outcrop called "Shaler" and a pitted outcrop called "Point Lake."
  • Shaler might be a river deposit. Point Lake might be volcanic or sedimentary. A closer look at them could give us better understanding of how the rocks we sampled with the drill fit into the history of how the environment changed

  • ...11 more annotations...
  • the team now drives the rover with added precautions, thoroughly checks the condition of Curiosity's wheels frequently, and is evaluating routes and driving methods that could avoid some wheel damage
  • A dune about 3 feet (1 meter) high spans the gap between two scarps that might be a gateway to a southwestward route over relatively smooth ground
  • The team is using images from the rover to assess whether to cross the dune
  • Other routes have also been evaluated for getting Curiosity from the rover's current location to a candidate drilling site
  • That site lies about half a mile (800 meters) away by straight line, but considerably farther by any of the driving routes assessed
  • This area is appealing because we can see terrain units unlike any that Curiosity has visited so far.
  • To prepare for destinations farther ahead, engineers are using a test rover at JPL to check the rover's ability to tolerate slight slippage on slopes while using its drill
  • With the drill bit in a rock, tests simulating slips of up to about 2 inches (5 centimeters) have not caused damage
  • Other testing at JPL is evaluating possible driving techniques that might help reduce the rate of wheel punctures, such as driving backwards or using four-wheel drive instead of six-wheel drive.
  • Some of the wheel damage may result from the force of rear wheels pushing middle or front wheels against sharp rocks, rather than simply the weight of the rover driving over the rocks

  • This removes previous uncertainty about the ratio in the Martian atmosphere from 1976 measurements from NASA's Viking project and from small volumes of argon extracted from Martian meteorites
  • The ratio is much lower than the solar system's original ratio, as estimated from argon-isotope measurements of the sun and Jupiter
