dirty space news: mars edition

nope, this is not a mistaken face on mars.   this is definitely high-resolution, exciting dirty space news! i'm posting this in honor of curiosity's landing on mars this week, even though the image below was taken by NASA's mars odyssey satellite that is orbiting around the red planet!

when a chunk of rock falls to the surface of a planet, it is called a meteorite and its impact produces a crater.  if that chunk of rock happens to split into two pieces right before it hits the ground, it creates two blast regions that overlap with a wall between.   the impact causes an ejection of material to shoot out... and i think that's all i need to say about that.


thanks to phil plait for showing me this marssack ;)
