A nice collection of clouds photographed by Curiosity, so much for the barren planet, in this nice article from NASA: https://www.nasa.gov/feature/jpl/nasa-s-curiosity-rover-captures-shining-clouds-on-mars This post has been automatically translated. See the original post here.

At 15:55:30 LMST the Rear Left Hazcam recorded again an incredible Martian rainbow extended from side to side.If in the photo of Sol 43 it was vaguely questionable the possibility of a reflection of sunlight entering in a grazing way between the camera lenses (see https://www.facebook.com/PianetaMarte.MdM/photos/3810030972413401), in this case this possibility is categorically excluded!As you can see from the direction of the shadows, here the sunlight comes from behind the camera, thus totally excluding the possibility that it could have illuminated the lens of the camera itself that here instead were in shadow!So, if it is definitely not a reflection of the Sun between the lenses, what generates these rainbows on Mars?What is special in this crater to generate recurrent rainbows, never observed before by other rovers and landers?The original image has undergone noise reduction due to compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.

With propellers that are supposed to be spinning at fantastic speeds to compensate for the rarefaction of the tenuous Martian atmosphere, how is it possible to take photos where the propellers themselves appear as sharp as if they were stationary?

Your browser does not support HTML video. I translate from the source cited below:“NASA’s Martian helicopter Ingenuity took these images during its fourth flight, on April 30, 2021, using its navigation camera. The camera, which tracks surface features beneath the helicopter, takes images at a speed where the helicopter’s blades appear locked in place, despite making 21 full rotations between each image. In flight, the blades spin at 2537 rpm (revolutions per minute). The images are aligned entirely using Ingenuity’s on-board position tracking system highlighting the stability and accuracy of the navigation algorithm.” Clearly, I’m preparing a tasty follow-up!

Your browser does not support HTML video. Ingenuity’s shadow is too sharp and the blades appear to us as if they were still or as if the photo had been taken with an exposure time too short compared to the possibilities of the camera that made it.What is actually behind this photo?
