Happy Valentine's Day from Mars

Greetings to all of you fine students on this, the 14th day of February. Coming to you all the way from planet Mars is a special Valentine's Greeting. These "craters" are not really craters at all, but clear evidence of intelligent Martians who inhabit the red planet and only want the earthlings to know how much they are loved. So, they have sent us a special message of love ... from over 50 million kilometers away.

 

Happy Valentine's Day
