NASA's MAVEN continues to advance Mars science and telecommunications relay efforts

With a suite of new national and international spacecraft primed to explore the Red Planet after their arrival next month, NASA's MAVEN mission is ready to provide support and continue its study of the Martian atmosphere.
MAVEN launched in November 2013 and entered the Martian atmosphere roughly a year later. Since that time, MAVEN has made fundamental contributions to understanding the history of the Martian atmosphere and climate. A few science highlights include:
- Determination that the bulk of the Martian atmosphere has been lost to space through time, driving changes in the Mars climate and the ability to support life at the surface.
- Characterization of the mechanisms by which gas is stripped away from the atmosphere to space and of the role of solar storms hitting Mars in enhancing the escape rate.
- There is significant unexpected variability in the loss rate of hydrogen to space through the seasons, which has important implications for the history of water.
ExoMars orbiter's 20,000th image

The CaSSIS camera onboard the ExoMars Trace Gas Orbiter has captured its 20,000th image of Mars.
The image, taken on 13 December 2020, features Solis Dorsum, a segment of a prominent wrinkle ridge system in a vast volcanic plateau, known as Tharsis. Wrinkle ridges are tectonic features that form in layered basalt lavas due to loading and flexure of the planet's crust and upper mantle. These tectonic stresses are caused by the planet's interior cooling and subsequent contraction.
The study of wrinkle ridges, and in particular their distribution and orientation, can reveal details of the complex and dynamic geological history of Mars.
