On Tuesday, a team of planetary science and astrobiology researchers released a detailed new report called a decadal survey, which lays out research priorities for their field. Like the census, a decadal survey comes out every 10 years and has important political implications. The previous assessment by planetary scientists prioritized a Mars sample return mission and a probe to Jupiter’s moon Europa—the federal government agreed to fund those in the 2020s. This time, the researchers argue that a Uranus orbiter and probe should be considered “the highest-priority new flagship mission” that could be developed and even launched within the next decade. Their second-place choice is to search for life on Saturn’s moon Enceladus, which harbors an underground ocean, a tiny bit of which sprays out in plumes.
