Possible Detection of Nitrates on Mars by the Sample Analysis at Mars (SAM) Instrument [PDF]

, 2013
Planetary models suggest that nitrogen was abundant in the early Martian atmosphere as dinitrogen (N2). However, it has been lost by sputtering and photochemical loss to space [1, 2], impact erosion [3], and chemical oxidation to nitrates [4].
