We are entering a new dawn of Mars exploration: Perseverance rover touched down on Mars earlier this year, which marks the start of what will be a decade-long effort to return samples from Mars. In 2022 the European Space Agency (ESA) will launch the ExoMars rover, which will team up with the ExoMars Trace Gas Orbiter (TGO) to find evidence of past or present life on Mars.

Paper: Mud flow levitation on Mars: Insights from laboratory simulations
Authors: Petr Brož et al.,
The Mariner spacecraft’s first images of Mars in the 1960s and 70s showed large volcanoes and flow features, most likely lava or mud. These features were largely interpreted to be lava flows because they look similar to those seen on Earth. However, a 2020 study by Brož et al., shows that mud flows may be more prevalent on Mars than first hypothesized.

Paper: Constraints on the shallow elastic and anelastic structure of Mars from InSight seismic data
Authors: Philippe Lognonné et al.,
Scientists are able to ‘see’ the internal structure of the Earth based on seismic waves recorded during Earthquakes. Earthquakes send seismic waves out in all directions with two main types: (1) surface waves are the major culprits of Earthquake damage as they remain on the surface; (2) faster body waves can travel down within Earth’s interior. The body waves are the fastest seismic waves, consisting of the first (primary; P-wave) and second (secondary, S-wave) waves to arrive at a location away from the epicentre of an Earthquake.
