The clouds were so faint that NASA employed special imaging techniques to spot them.
"Martian clouds are very faint in the atmosphere, so special imaging techniques are needed to see them," JPL said in the blog post."Multiple images are taken to be able to get a clear, static background. That allows anything else moving within the image — like clouds or shadows — to become visible after subtracting this static background from each individual image."The clouds were captured in two eight-frame movies captured Dec.
Curiosity used its navigation camera twice to examine the clouds from two different perspectives, JPL said. Two views allows scientists to calculate the clouds' speed and height, JPL said, which in turn provides clues about their composition.
