Scientists Say They Have Come Up With a Potential Way To Make Oxygen On Mars
An anonymous reader quotes a report from CNN: In a high-stakes mission that could take five years to complete, NASA wants to land astronauts on Mars in the 2030s. Transporting enough oxygen and fuel on a spacecraft to sustain the mission for anywhere near that length of time, however, isn’t currently viable. The way NASA plans to address this problem is…
Curiosity rover spots signs of ancient megafloods on Mars
We already know that Gale Crater on Mars used to hold a lake or series of lakes a few billion years ago. Now, NASA’s Curiosity rover has found evidence for ancient giant floods that washed through the region as well. Source: https://earthsky.org/space/megafloods-gale-crater-mars-life-curiosity-rover…
Creating chaos: Craters and collapse on Mars
Elevation can be deceiving in satellite imagery of Mars, even when differences are extreme—as demonstrated by this image of Pyrrhae Regio from ESA’s Mars Express. A chunk of terrain has collapsed and dropped more than four kilometers below its surroundings, illustrating the incredible contrast and dynamism seen across the martian surface.

Radar reveals 3 more subsurface polar lakes on Mars
Scientists with the European Space Agency say that the Mars Express orbiter has found evidence of three more salty lakes below Mars’ south pole. The discovery comes two years after the first lake was detected in 2018. Source: https://earthsky.org/space/3-more-subsurface-lakes-mars-south-pole…
Billion-year-old Martian dunes reveal planet’s history

The way forward to Mars
The path that ExoMars 2022 will follow to reach the Red Planet is set. The trajectory that will take the spacecraft from Earth to Mars in 264 days foresees a touchdown on the martian surface on 10 June 2023, at around 17:30 CEST (15:30 UTC). Source: https://phys.org/news/2020-10-mars.html…
Amazing photos in Mars Reconnaissance Orbiter celebration
NASA has posted a sampling of some of the most awe-inspiring photos of Mars, to celebrate the 15th anniversary of the launch of Mars Reconnaissance Orbiter.

NASA scientists leverage carbon-measuring instrument for Mars studies
Insights and technology gleaned from creating a carbon-measuring instrument for Earth climate studies is being leveraged to build another that would remotely profile, for the first time, water vapor up to nine miles above the Martian surface, along with wind speeds and minute particles suspended in the planet’s atmosphere.
