ARRAKIHS, or Analysis of Resolved Remnants of Accreted galaxies as a Key Instrument for Halo Surveys, is a planned mission by European Space Agency. It will study dark matter haloes of galaxies. It was selected in 2022, and is expected to be launched "in the early 2030's". It will observe 75 galaxies for 150 hours each. It is a F-class ("fast") mission. The mission is named after a planet Arrakis from science fiction novel Dune.
