This dark object was discovered in Sol 644 by Streetcap1 of Youtube. I looked for other images of the mountain area, but none were of this exact location. The black UFO was not in any other photos. The photo label says Navcam: Right B
Although the black UFO could be a alien drone, it does look like a flying black beetle. Its shape resembles a black cicada, which on Earth has transparent wings.
This black object looks like its flying and not sitting on the mountain. The mountain is blurred and faded, there are no such black objects anywhere on that mountain as seen in other photos of Sol 644. It had to have flown past as the rover was taking a photo. So here we are again, looking at a biological life form flying past the rover. Don't expect NASA to talk about it, they never do. If they did, every country in the world would be sending probes to Mars to explore for possible alien contact...and that could jeopardize Americas position as a world power. The two Russia did send, were destroyed...by the US of course. SCW
