Methane Sensor for Mars (MSM), on‐board Mars Orbiter Mission (MOM) is a differential radiometer based on FPE (Fabry‐Perot Etalon) filter which measures column density of methane in the Martian atmosphere. It is the first FPE sensor ever flown to space. As MOM mission completes its first 100 orbits around Mars, MSM has already collected large volume of data completely covering the low latitude regions from 30°S to 40°N.
