Mars MetNet

Mars MetNet was a planned atmospheric science mission to Mars initiated by the Finnish Meteorological Institute together with Russia and Spain. Its objective was to set up a widespread surface observation network to study the structure, physics and meteorology of the Martian atmosphere. The bulk of the mission was to consist of at least sixteen MetNet impact landers deployed across the surface. By September 2013 two flight-capable entry, descent and landing systems had been built and tested, and as of 2015 baseline funding existed until 2020. As of 2016 neither a launch vehicle nor a launch date had been set, so the mission never flew and remains a plan.
