Un OVNI photographié par Curiosity ?

An amazing video has been posted to YouTube of the strangest object ever captured by a NASA rover as it photographed its environment, showing what looks like a spacecraft flying past, high in the sky, and leaving a distinctive vapor trail jetting from its tail.

What is it?



The video, posted by prolific UFO hunter Streetcap1 on Friday, has surprisingly few views. Perhaps it's because the channel has a dubious reputation for source material, with critics saying SC1 often fakes images for more channel views and subscriptions.

But, this time, there can be no doubt about the authenticity, unless NASA itself is in the UFO hoaxing business.

The image was published by the space agency recently and the UFO can be clearly seen trailing skywards in the right hand, upper corner.



In the original, the unidentified flying object doesn't look like much, being relatively smaller than the foreground photographed by the rover.

But, enlargement of the object reveals a spherical top cone, a rounded center mass and what looks like some kind of propellant ejecting from its tail.

Does Mars have its own space program?

If not, then what is this thing?
