Exploration of Uranus In 2011, the United States National Research Council recommended a Uranus orbiter and probe as the third priority for a NASA Flagship mission by the NASA Planetary Science Decadal Survey. However, this mission is considered to be lower-priority than future missions to Mars and the Jovian System.<ref name="2013-2022/Decadal"></ref> A mission to Uranus is one of several proposed uses under consideration for the unmanned variant of NASA’s heavy-lift Space Launch System (SLS) currently in development.
