WEBMars is one of the easiest planets to spot in the night sky – it looks like a bright red point of light. Despite being inhospitable to humans, robotic explorers – like NASA's Perseverance rover – are serving as pathfinders to eventually get …
Mars’ missing atmosphere could be hiding in plain sight
WEBSep 25, 2024 · Caption: This schematic illustrates the progressive alteration of iron-rich rocks on Mars as the rocks interact with water containing CO2 from the atmosphere. Over several billion years, this process could have stored enough CO2 in the clay surface, in the form of methane, to explain most of the CO2 that went missing from the planet’s early …
