Space News



 Hello Troops,
We set our clocks back to Standard Time early this morning.  The nights are getting longer and longer as the Earth revolves around the Sun to the Winter Solstice on December 21.  

You can see where the Earth is now on the graphic above as we inch our way closer and closer to the first day of Winter. 
Our days are growing shorter because of the Earth's tilt of 23.4 degrees. 


In this picture you see that the Earth's tilt in the Winter means less sunlight on the Northern Hemisphere.  Our days are shorter because of it and temperatures drop.


Those people living in the Southern Hemisphere move into the summer in December.  You see that the Earth's tilt gives them more direct sunlight and longer days.  


Curiosity Rover finds no methane on Mars.  
A Bad Sign for Life.



NASA's Mars rover Curiosity has detected no methane in its first analyses of the Martian atmosphere — news that will doubtless disappoint those who hope to find life on the Red Planet.
Living organisms produce more than 90 percent of the methane found in Earth's atmosphere, so scientists are keen to see if Curiosity picks up any of the gas in Mars' air. But the 1-ton rover has come up empty in the first atmospheric measurements taken with itsSample Analysis at Mars instrument, or SAM, researchers announced today (Nov. 2).



Like a tourist who snaps a photo of himself in front of the Eiffel Tower, NASA's Mars rover Curiosity has stretched out its arm and captured a high-resolution self-portrait in spectacular surroundings.
The 1-ton Curiosity rover took 55 hi-res pictures with its Mars Hand Lens Imager camera, or MAHLI, on Oct. 31. Mission scientists then stitched the images together to create a full-color mosaic of Curiosity and its Gale Crater landing site.
