# Independent confirmation of a methane spike on Mars and a source region east of Gale Crater

Marco Giuranna, Sébastien Viscardy, Frank Daerden et al., 2019. _Nature Geoscience 12(5), 326–332_.

Mars Express PFS data recorded methane over the Gale region a day after a Curiosity spike in June 2013, and atmospheric modelling places a likely source region east of the crater.
