I was looking over the newest batch of Curiosity Rover photos on the NASA site and found something in the sky that NASA over looked. At first I thought it was a meteor, then I realised the darker end was the front and the lighter end was its tail, so this object was coming from the Mars surface! 

Also it appears that the object dropped off part of itself. If you look at the screenshot above, you will notice a small black dot below it. The UFO dropped off a small exploration orb and it was caught on NASA camera. I now understand why NASA didn't want to report this to the public.
