Early results from the Mars Orbiter Mission Methane Sensor for Mars (MSM) instrument
The Methane Sensor for Mars has two channels, one sensitive to methane and one to measure the background reflectance of Mars at a wavelength of 1.65 microns (a wavelength at which methane is transparent) for calibration purposes. The reflectance of Mars in this reference channel will be compared to its reflectance in a channel where methane is opaque to measure the abundance of atmospheric methane. This graphic contains data acquired up to December 15, 2014.
