Manganese oxides are thought to be a signature of atmospheric oxygen. But on the Red Planet, recent results suggest they might be more of a red herring.
The middle atmosphere of Mars is a critical region influenced by both waves from below and solar radiation from above, but until now there have been very few observational constraints on this region.
The impact sent surface waves rippling over the Martian surface all the way to NASA’s InSight lander, giving scientists a rare view of the planet’s outer layer.
In a stroke of luck, the SuperCam microphone on Perseverance was turned on the moment a dust devil swept directly over the rover.
High-resolution imagery of newly discovered paleolakes shows a period of consistent liquid water flow.
By studying these literal chunks of Mars, scientists are learning more about the Red Planet’s deep interior and impact history.
Seismic signals detected by the InSight lander show that the planet’s lower mantle may be less homogenous than previous models have suggested.
Solar occultation observations from the ACS/MIR instrument provide coincident profiles of O3, H2O and temperature, shedding light on correlations and unveiling knowledge gaps in Mars’s photochemistry.
The discovery of tridymite in Mars’s Gale Crater triggered debate about the rare mineral’s origins. A research team recently suggested a scenario with explosive implications.
Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
