Using the navigation cameras on its mast, NASA's Curiosity Mars rover took these images of clouds just after sunset on March 28, 2021, the 3,072nd so, or Martian day, of the mission. These noctilucent, or twilight clouds, are made of water ice; ice crystals reflect the setting sun, allowing the detail in each cloud to be seen more easily.
