NASA's Mars Curiosity rover has made consistent and puzzling findings, detecting mysterious puffs of methane gas at night in Mars' Gale Crater, sparking intrigue about the source and significance of the gas.
Experiments by NASA scientist Alexander Pavlov indicated that fluctuations in temperature and air pressure on Mars may have caused a solidified salt layer to trap gases, potentially explaining the methane spikes detected by the SAM instrument.
While the layer under the salt may have been disturbed by Curiosity's movements, leading to increased methane levels, the odd seasonality and night-specific appearance of the gas spikes remain unexplained.
Limitations in detecting methane release on Mars persist due to the rover's competing priorities, posing challenges for researchers to fully understand the dynamics of methane emissions.
