Get excited about Uranus (and so much more).
Of these proposed flagship missions, the committee determined that NASA's top priority should be developing a flagship-class mission to— what could be a $4 billion endeavor. A combination of factors pushed the concept of a Uranus orbiter and probe into first place, including both the science potential offered by finally getting a close-up look at a so-called"ice giant" and the feasibility of the mission.
"Uranus itself is one of the most intriguing bodies in the solar system," committee members wrote in the document. In addition, the committee emphasized that finally developing a dedicated mission to one of the ice giant planets — Uranus or its neighbor, Neptune — was a vital priority, but noted that the logistics of a Neptune mission during the years in question were challenging.
, a perhaps $5 billion spacecraft that would orbit and land on Saturn's small icy moon. This mission would orbit the moon for about 1.5 years, then spend two years at work on its surface, analyzing scoops of the icy material.With eight planets, more than 200 moons and countless smaller objects rattling through the solar system, planetary scientists face a rich buffet of exploration opportunities.
In fact, exoplanet science is one key reason the decadal survey team cited for prioritizing a flagship mission to Uranus."Exoplanets with similar masses are perhaps the most abundant class of exoplanet, and an inherently different class of planet than gas-rich Jupiter and Saturn," scientists wrote.
