Uranus Pathfinder (UP) is a proposal for an ESA Medium-class mission to the planet Uranus that is being proposed to ESA’s M4 call for missions which closes on 16 January 2015. It follows a proposal submitted to M3 in 2010 (Arridge et al., 2011) and white papers written by the European community in 2013 (ODINUS, Uranus, Neptune).

The concept for M4 involves an ESA-NASA collaboration leading to an orbiting spacecraft arriving in the Uranian system in 2037 with a launch in January 2025.
