MAVEN probe captures incredible ultraviolet images of Mars
Miscellaneous / / June 23, 2023
NASA MAVEN spacecraft stripped off Mars in the ultraviolet. This was done thanks to the Imaging Ultraviolet Spectrograph (IUVS) camera mounted on the probe.
The footage was taken in July 2022 and January 2023. One photo captured the summer season in the southern hemisphere, and the second - the northern hemisphere.
The IUVS camera is capable of detecting wavelengths between 110 and 340 nanometers outside of the visible spectrum. In order for the human eye to see them, the images must be reproduced at different brightness levels in the three ultraviolet wavelengths—red, green, and blue.
With this optimization, atmospheric ozone turns purple, while clouds and haze turn white or blue. The surface becomes yellowish-brown or green (depending on the contrast setting and the level of detail).
MAVEN launched in November 2013. The spacecraft entered Mars orbit in September 2014. Since then, he has been exploring the planet's upper atmosphere and ionosphere, as well as its interaction with the Sun and solar wind. With this probe, scientists want to better study the process of destruction of the Martian atmosphere.
