Mars mission captures Red Planet like we’ve never seen it before.

NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission acquired "stunning views" of Mars in two ultraviolet images taken at different points along our neighboring planet’s orbit around the Sun.

By viewing the planet in ultraviolet wavelengths, scientists say they can gain insight into the Martian atmosphere and view surface features in remarkable ways.

MAVEN’s Imaging Ultraviolet Spectrograph (IUVS) instrument obtained these global views of Mars in 2022 and 2023 when the planet was near opposite ends of its elliptical orbit.

The IUVS instrument measures wavelengths between 110 and 340 nanometers, outside the visible spectrum.

To make these wavelengths visible to the human eye and easier to interpret, the images are rendered with the varying brightness levels of three ultraviolet wavelength ranges represented as red, green, and blue.

In this color scheme, atmospheric ozone appears purple, while clouds and hazes appear white or blue.

The surface can appear tan or green, depending on how the images have been optimized to increase contrast and show detail.

The first image was taken in July 2022 during the southern hemisphere’s summer season, which occurs when Mars passes closest to the Sun.
