This image shows an artist concept of NASA Mars Atmosphere and Volatile Evolution MAVEN mission.

The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission will determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time.

Citizen Science Project

Using data collected from MAVEN's Imaging Ultraviolet Spectrograph (IUVS), you can help answer understand Mars' atmosphere and climate. Questions include:

What are the daily, seasonal, or annual patterns in Martian cloud shapes and distributions?
How well do cloud forms reflect prevailing wind patterns?
Do the structural similarities between Earth and Mars' cloud types point to similar formation mechanisms?

A series of four full disc images of Mars show clouds moving across the globe.

Ultraviolet Mars Reveals Cloud Formation: The ultraviolet colors of the planet have been rendered in false color, to show what we would see with ultraviolet-sensitive eyes. This images uses four MAVEN images to show about seven hours of Mars rotation during this period, and interleaves simulated views that would be seen between the four images.

Mars 2020: Perseverance Rover

NASA’s Perseverance Mars rover took this selfie on July 23, 2024, the 1,218th Martian day, or sol, of the mission. To the left of the rover near the center of the image is the arrowhead-shaped rock nicknamed “Cheyava Falls,” which has features that may bear on the question of whether Mars was home to microscopic life in the distant past. The small dark hole in the rock is where Perseverance took a core sample, which is now in a sample tube stored in the rover’s belly. The white patch to the right of the hole is where the rover used an abrasion tool to clear away the top surface, allowing science instruments to study the rock’s composition.
