Mars: January 2022



New Curtin University research has confirmed the frequency of asteroid collisions that formed impact craters on Mars has been consistent over the past 600 million years.


The crater in the center of this HiRISE image defines where zero longitude is on Mars, like the Greenwich Observatory does for the Earth.


After analyzing powdered rock samples collected from the surface of Mars by NASA's Curiosity rover, scientists today announced that several of the samples are rich in a type of carbon that on Earth is associated with biological processes.


This image shows a small light-toned exposure of rock on the plains of Terra Sirenum, in a heavily cratered region of the Southern Hemisphere of Mars.


Megaripples, intermediate-scale bedforms caused by the action of the wind, have been studied extensively and thought to be largely inactive relics of past climates, save for a few exceptions.


This image shows us great examples of transitioning streaks in Arabia Terra.


This public suggestion wanted to get a closer look at an area in Isidis Planitia that might have been carved out by landslide.


On Wednesday, Dec. 29 (sol 306) Perseverance successfully cored and extracted a sample from a Mars rock. Data downlinked after the sampling indicates that coring of the rock the science team nicknamed Issole went smoothly.


In this scene, there is contact between a ridged unit and a presumably underlying non-ridged unit.


When our camera is pointed straight down at the surface of Mars, we call this "nadir."


Billions of years ago, a river flowed across this scene in Mawrth Vallis.


China's National Space Administration has released some stunning imagery taken by the Tianwen-1 orbiter currently in circling Mars.
