"Atmospheric Pressure Changes Drive Methane Pulses on Mars"

New research suggests that fluctuations in atmospheric pressure on Mars may be responsible for releasing subsurface methane into the planet's atmosphere, posing a challenge for detecting signs of life. Simulations indicate that methane pulses from underground occur just before sunrise in the planet's northern summer season, aligning with previous rover data. This information is crucial for NASA's Curiosity rover's sampling campaign, providing key time windows for data collection to better understand methane fluctuations and potentially uncover the source of methane on Mars.
