Story summary

NASA's Uranus Orbiter and Probe (UOP), highlighted in the 2022 Decadal Survey, faces distance and launch-vehicle challenges.
SpaceX's Starship, recently successful in tests, could enable in-orbit refueling and an aerobraking shield.
These capabilities could cut travel time to about six and a half years.
But UOP funding remains uncertain, and missing the 2030 windows could push the mission to mid-2040s, the gap since the 1986 Uranus mission.
