Long UFO seen on Mars by Curiosity rover

Curiosity Rover has again photographed a luminous and white UFO near or above the fourth from the Sun, that is to say Mars.  Is Scott C. Waring who discovered this new proof on the website of the NASA, on May 21, 2014.

Scott C. Waring reports:

I was looking through todays Mars rover photos and found an object in the distance. This object matches the description of the UFO seen by the same rover on April 28, 2014 and on May 4, 2014. The end of the object is glowing due to the angle of the sunlight and the long body is lighter in color. When you add contrast and lighting you can see its detail of the body better. I have messaged NASA about this UFO in the two earlier sightings (April 28) and (May 4), however NASA refuses to answer. SCW
