NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft captured two captivating ultraviolet images of Mars, providing unique insights into its atmosphere, seasonal changes, and surface details.
The images were taken at different points in Mars' orbit around the Sun, revealing new information about the planet's climate history and potential habitability.
MAVEN Spacecraft Takes Ultraviolet Pictures of Mars
New ultraviolet images of Mars reveal psychedelic hues and unique atmospheric features. As per Mashable, the Martian ozone appears in vibrant colors like Kool-aid Purplesaurus Rex, while clouds and hazes resemble cappuccino foam or antifreeze blue when rendered in UV wavelengths.
The red surface, caused by oxidized iron, appears more like khaki or verde marble. As per NASA's Mars Exploration website, the images were captured by MAVEN at different points in Mars' orbit around the sun.
In the first image, taken in July 2022 during the southern hemisphere's summer, the Argyre Basin shows a pinkish hue due to atmospheric haze, while Valles Marineris appears tan with clouds. The southern polar ice cap is seen shrinking from the warmer weather.
During Mars' summer, the southern polar ice caps shrink due to warmer temperatures, leading to the release of carbon dioxide and a thicker atmosphere. According to Space.com, MAVEN has observed increased hydrogen loss during this season. This loss is believed to be caused by dust storms pushing water vapor to higher altitudes.
The second image was taken on January 2023 and highlights the seasonal changes, with the northern polar region appearing white with clouds. Valles Marineris and craters retain their tan colors. NASA notes the buildup and destruction of ozone during the northern winter and spring seasons.
These images provide valuable insights into Mars' atmosphere, seasonal variations, and surface details. MAVEN's observations contribute to understanding the planet's climate history and its potential habitability.

Scientists Gain New Insight from the UV Images of Mars
The study of Mars' atmosphere through the MAVEN mission's Ultraviolet Spectrograph provides valuable scientific information rather than mere visual appeal. As Mashable reported, this instrument measures wavelengths of light that are invisible to the human eye, allowing astronomers to analyze the loss of volatiles, such as water and carbon dioxide, from the Martian atmosphere.
These volatile molecules were released into the atmosphere from Mars' interior and crust through volcanic plumes. By studying these processes, scientists gain insights into Mars' climate history, including its past liquid water and potential habitability.
The MAVEN mission, which marks its 10-year anniversary in the fall of this year, has been orbiting Mars since September 2014. Initially planned to last for two years, the mission has exceeded expectations and continues to operate with enough fuel to last until 2030.
The long duration of the mission has allowed for a comprehensive study of Mars, providing a deeper understanding of its atmospheric dynamics and evolution over time.
The information gathered through MAVEN's observations contributes to our knowledge of Mars' atmospheric loss, which, in turn, sheds light on the planet's climate history, the existence of liquid water in the past, and the potential for habitability. This research is crucial for unraveling the mysteries of the Red Planet and advancing our understanding of other planets within our solar system.
