HRSC and CaSSIS observations
The northern rim of Korolev crater was also imaged by the CaSSIS camera on board ExoMars as one of the first places on Mars on 15 April 2018, only some days after HRSC recorded the crater in orbit 18042. ExoMars is an ESA space program dedicated to the search of life on Mars. It consists of two parts: the ExoMars 2016 mission brought the Trace Gas Orbiter into a Mars orbit in 2016, but failed to deliver successfully the landing module Schiaparelli to the surface of Mars. For the near future, the ExoMars 2020 mission is planned, comprising a surface platform and a rover that should land in Oxia Planum, at the dichotomy boundary of Mars in 2021.
