Team members working with NASA’s Curiosity Mars rover created this “postcard” by commanding the rover to take images at two times of day on Nov. 18, 2025, spanning periods that occurred on both the 4,722nd and 4,723rd Martian days, or sols, of the mission.

The panoramas were captured at 4:15 p.m. on Sol 4,722 and 8:20 a.m. on Sol 4,723 (both at local Mars time), then merged together. Color was later added for an artistic interpretation of the scene with blue representing the morning panorama and yellow representing the afternoon one. The resulting “postcard” is similar to ones the rover took in June 2023 and November 2021. Adding color to these kinds of merged images helps different details stand out in the landscape.
