　　The robots, each weighing 150 kilograms, can cover 100 meters per day．They are designed to be able to examine the mineral content(矿物质)of the soil, and their special camera will take pictures of the lands and hills．Although they will be under control from Earth, the robots, are able to move more freely compared to those sent up before them．

     LOS ANGELES-Once in a blue moon there is one on New Year's Eve.Revelers (狂欢者) ringing in
2010 will be treated to a socalled blue moon.According to popular definition, a blue moon is the second
full moon in a month.But don't expect it to be blue-the name has nothing to do with the color of our
closest space neighbor.
     A full moon occurred on Dec.2,2009.It will appear again on Thursday in time for the New Year's
countdown.
     "If you're in Times Square, you'll see the full moon right above you.It's going to be that brilliant, " said
Jack Horkheimer, director of the Miami Space Transit Planetarium and host of a weekly astronomy TV
show.
      The New Year's Eve blue moon will be visible in the United States, Canada, Europe, South America
and Africa.For partygoers in Australia and Asia, the full moon does not show up until New Year's Day,
making January a blue moon month for them.
     However, the eastern hemisphere can celebrate with a partial lunar eclipse (月偏蚀) on New Year's
Eve when part of the moon enters the Earth's shadow.The eclipse will not be visible in the Americas.
      A full moon occurs every 29.5 days, and most years have 12 ones.On average, an extra full moon in
a month-a blue moon-occurs every 2.5 years.The last time there was a blue moon was in May 2007.
New Year's Eve blue moons are rarer, occurring every 19 years.The last time was in 1990.
     Blue moons have no astronomical significance, said Greg  Laughlin, an astronomer at the University
of California, Santa Cruz."' Blue moon' is just a name in the same sense as 'a hunter's moon'  or 'a
harvest moon', "  Laughlin said in  an email.
     The popular definition of blue moon came about after a writer for, Sky & Telescope magazine in
1946 misinterpreted (误解) the Maine Farmer's Almanac (历书) and labeled a blue moon as the
second full moon in a month.In fact, the almanac defined a blue moon as the third full moon in a season
with four full moons, not the usual three.Though Sky & Telescope corrected the mistake decades later,
the definition caught_on.
