The robot "Curiosity" photographed the same UFO with a tail for the second time in the sky of the Red Planet
The UFO is visible in a picture taken with one of NASA's Mars Science Laboratory Curiosity cameras - the one on the back of the body called the Rear Hazcam and equipped with a wide-angle lens. A UFO is visible on the horizon slightly to the right. Its outlines are vague, but a certain cone is clearly visible, resembling either a rocket exhaust, or a contrail.
May UFO is larger
The cone is directed downward. Therefore, it is possible that the object takes off due to jet thrust.
The picture was taken on May 21, 2014 (636 Martian day) at 15:27 hours 34 seconds. But the exact same UFO was already in the frame. Filming with a Front Hazcam mounted on the front of the case, Curiosity captured it on January 5, 2014 (504 Martian days) at 2326 hours 37 seconds. The object also seems to take off. But at a different angle and in the other direction.
January UFO

January UFO larger
Is the subject in the May picture the same as in the January one? Or are they just similar, like one of our Proton rocket to another? In the latter case, it is possible that someone regularly launches something into the Martian sky. But not earthlings - that's for sure.
Both UFO images are posted on the official NASA website, January - here, May - here.
One can, of course, assume that UFOs are some kind of defect. But in the pictures taken with the same cameras on other days, there is nothing like this.
