Multiple scientific studies confirm that the Curiosity rover has successfully measured atmospheric methane within Gale crater using its onboard tunable laser spectrometer.

The analysis

The retrieved papers clearly document that the Curiosity rover utilized its Sample Analysis at Mars (SAM) instrument suite, specifically the tunable laser spectrometer, to accurately detect and measure baseline and elevated levels of atmospheric methane at Gale crater.
