Mars: October 2021



This image shows the very steep outer scarp of the north polar layered deposits. Every year there is a lot of slope activity in the springtime when sunlight warms these slopes.


This HiRISE image shows gullies on a crater wall in the north polar region of Mars.


Researchers at the Georgia Institute of Technology have developed a concept that would make Martian rocket fuel, on Mars, that could be used to launch future astronauts back to Earth.


On the floor of this crater where there are no dunes, the ice forms an uninterrupted layer.


Thanks to two microphones aboard NASA's Perseverance rover, the mission has recorded nearly five hours of Martian wind gusts, rover wheels crunching over gravel, and motors whirring as the spacecraft moves its arm.


Pictures from NASA's latest six-wheeler on the Red Planet suggest the area's history experienced significant flooding events.


A new report from the National Academies of Sciences, Engineering, and Medicine identifies criteria that could allow robotic missions to certain locations on Mars to be carried out with less restrictive "bioburden" requirements, which are designed to prevent the unintentional transport of Earth-based microbes to Mars.
