On Mars Orbiter Mission’s (MOM) second anniversary of Mars arrival, ISRO has (finally!) made available to the public data from its first year in orbit. As expected, there are no dramatically new science results. The most anticipated results were from the Methane Sensor for Mars (MSM), which unfortunately hasn’t found any methane on the planet. This does not necessarily imply that there is no methane at Mars, only that MSM is likely not sensitive enough to sense trace amounts of methane that are present.
Other payloads include the Lyman Alpha Photometer (LAP), which studies the abundance of deuterium and hydrogen in the atmosphere, the Thermal Infrared Imaging Spectrometer (TIIS) to study and map the mineral surface of Mars, and the Mars Exospheric Neutral Composition Analyser (MENCA), a neutral gas spectrometer. MENCA’s science results were already published in a paper in March.
