Caption:

This sunset on Mars was captured by NASA's Perseverance Mars rover using its Mastcam-Z camera system on Nov. 9, 2021, the 257th Martian day, or sol, of the mission.

Martian sunsets typically stand out for their distinctive blue color . Fine dust in the atmosphere permits blue light to penetrate the atmosphere more efficiently than colors with longer wavelengths. But this sunset looks different: less dust in the atmosphere resulted in a more muted color than average. The color has been calibrated and white-balanced to remove camera artifacts.

Background Info:

The Mastcam-Z investigation is led and operated by Arizona State University in Tempe, working in collaboration with Malin Space Science Systems in San Diego, California, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Neils Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets.

A key objective for Perseverance's mission on Mars is astrobiology , including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA's Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
