Summary[edit]

Description	Français : Sources et lieux de stockage qui pourraient expliquer le méthane détecté dans l'atmosphère de Mars (libellés en francais) English: This image illustrates possible ways methane might be added to Mars' atmosphere (sources) and removed from the atmosphere (sinks). NASA's Curiosity Mars rover has detected fluctuations in methane concentration in the atmosphere, implying both types of activity occur on modern Mars. (french labels)
