NASA has shared stunning views of Mars in ultraviolet wavelengths. The images of the red planet were taken by an instrument on its MAVEN spacecraft, which launched in November 2013.
Four volunteers will live in NASA's Mars habitat for one year, helping the space center collect data for its first manned mission to the neighboring planet.Mars in stunning ultraviolet wavelengthsThe MAVEN spacecraft used its imaging ultraviolet spectrograph instrument to capture the remarkable views of the red planet in 2022 and this year, when Mars was near opposite ends of its elliptical orbit around the sun.
The instrument measures wavelengths between 110 and 340 nanometers, which is outside the visible spectrum. In order to make the wavelengths visible to the human eye, images are rendered with varying brightness levels of three ultraviolet wavelength ranges. They are represented as red, green and blue.Using these colors, the atmospheric ozone appears purple and white clouds appear white or blue.The first image was taken in July 2022, during the southern hemisphere’s summer season. That occurs when
