I think the riddle maybe solved then
But star for you OP, more people/digger/observers like you are much needed of we're ever to find a smoking gun
What do you mean "nice catch"? The images were posted by NASA on the public website where all the other rover images are posted, and news articles
about the Phobos captures were posted on the usual places (Red Planet Report etc) too. Don't make out like this is some secret pic that someone has
Posting a picture that you think looks a bit funny without taking a few minutes to ascertain what it is does not constitute "research" in my book.
Anyway now let's do some DENYING IGNORANCE...
Here is what you should have seen from the approximate location of Curiosity at 4:52:15 on 2014-04-28 (obviously the Stellarium landscape doesn't show
the hill in front of the rover)
And here is the image captured at that time:
Four minutes later at 4:56:09:
And the Curiosity image:
How about the latest series of images from sol 619? (Sorry the GIF comes out so huge!)
It's a rising moon, and again, looking at Stellarium we see Phobos rising in the west at just the right time:
Time of first image in series:
And last image in series:
Conclusion: Both "cylinders" are just Phobos, captured by the rover as it set and rose respectively.
Why does it appear as a streak? Because the exposure length is very long: two minutes for the Sol 613 images and more like three minutes for the Sol
619 ones. Phobos's angular diameter as seen from Mars is about 0.1-0.2 degrees (it varies), and in two minutes it travels about 1 degree across the
sky. So the length of the image should be very approximately 5 to 10 times its width, and a little more for the sol 619 images. Looks about right to
