Take a Plunge Into the Ice Giants

The unique atmospheric compositions of ‘ice giant’ planets Uranus and Neptune were recreated to simulate a plunge deep within them.

Our Solar System’s ice giants, Uranus and Neptune, have been largely left out of the planetary probe game. While all of the other planets—including even the demoted Pluto—have been the subjects of dedicated missions, the ice giants have not. In fact, the only spacecraft to ever even fly by Uranus and Neptune was Voyager 2 in the late 1980s.

Will We Ever Go Back to Explore the Ice Giants? Yes, If We Keep the Missions Simple and Affordable

Uranus and Neptune are begging to be visited, but expensive missions to visit them may never be approved.

It’s been over 35 years since a spacecraft visited Uranus and Neptune. That was Voyager 2, and it only did flybys. Will we ever go back? There are discoveries waiting to be made on these fascinating ice giants and their moons.

But complex missions to Mars and the Moon are eating up budgets and shoving other endeavours aside.

A new paper shows how we can send spacecraft to Uranus and Neptune cheaply and quickly without cutting into Martian and Lunar missions.
