Serendipitous observations by the Juno spacecraft while it was en route to Jupiter suggest a Martian source for the dust, but how the dust escapes Mars or its moons remains unknown.
Thanks to COVID-19, mission control for the Perseverance Mars rover will look emptier than previous missions, and fewer scientists and engineers will follow the rover’s schedule.
Exposure to sunlight creates telltale patterns in the polar ice cap that change over time, potentially providing insight into the climatic history of the Red Planet.
The last works of Marzieh (Mari) Foroutan, an early-career martian geologist who was lost to us in 2020, have now been completed and published in JGR: Planets.
Four-legged, autonomous robots known as “Mars Dogs” will explore previously inaccessible caves to look for signs of life and potential locations for future human colonies.
Amorphous materials generated from sulfur and chloride salts by electrostatic discharge in a Mars chamber suggest widespread electrical processes during dust activities.
Spacecraft find that Mars oscillates 10 centimeters off its axis of rotation.
A new workflow improves the process of creating massive, accurate mosaics from spacecraft-captured images of a planet’s surface.
Spacecraft observations and model simulations provide new insights into tidal patterns that transport momentum and energy into the planet’s upper atmosphere.
