An extensive report covering the next ten years of  American planetary science  and  astrobiology  has deemed it “priority” to send an  orbiter  and  probe  to  Uranus . Such a mission could potentially be launched in the early  2030s  with the assistance of  Jupiter’s gravitational pull .

Aiming for Uranus

Similar to Neptune,  Uranus  has only been visited once by humanity, thanks to the fleeting passage of the  Voyager 2  spacecraft in the late 1980s. Since then, this planet has been scrutinized solely by  ground-based instruments  or occasionally by the  Hubble Space Telescope . To complicate matters, this  ice giant  resides over  2.7 billion kilometers from Earth . However, it remains closer to the Sun than Neptune, which is situated over  4.3 billion kilometers  away.

For many years, several researchers have advocated for a mission to Uranus, and time is running out. An excellent launch opportunity is approaching; in the early  2030s , Jupiter will provide a unique  gravitational assist . By utilizing a sufficiently powerful rocket, like NASA’s  Space Launch System (SLS) , a mission could reach Jupiter in slightly under  two years  before heading toward Uranus.

Could such a mission soon materialize? According to the  decadal survey  conducted by the National Academies of Sciences, Engineering, and Medicine, which aims to shape U.S. funding and research efforts until  2032 , this is indeed possible. This extensive  780-page document  follows an earlier survey published in November, which set the astronomical objectives for the decade.

Astronomers Targeting Uranus and Enceladus

In this detailed  report , an interdisciplinary team led by  Mark Hofstadter  from NASA’s Jet Propulsion Laboratory proposes sending  two spacecraft  to explore Uranus. The initial orbiter would be tasked with mapping the planet’s  gravitational  and  magnetic fields . Once this data is gathered, it could deploy a  probe  tasked with diving into its hydrogen sulfide-rich atmosphere (indeed,  Uranus has quite the odor ).

The primary objectives of this ambitious mission would be to study  Uranus’s composition ,  structure , the nature of its  magnetic field , how its internal heat moves to the surface, and the specifics of its  atmosphere , moons, and  ring system .

This report is structured around various scientific themes, including  exoplanet studies ,  life on Earth , and how our  Solar System  formed and evolved. “This recommended portfolio of missions, high-priority research activities, and technological development will yield transformative advancements in human knowledge and understanding of the origin and evolution of the Solar System, as well as the life and habitability of other bodies beyond Earth,” said  Robin Canup  from the Southwest Research Institute and co-chair of the survey’s steering committee.

Following the Uranus mission, the second high-priority endeavor would involve sending an  orbiter and lander  to  Enceladus . This icy moon of  Saturn  is believed to harbor conditions favorable for the emergence of life as we know it.
