The Solar System is a busy place, with spacecraft currently visiting most of the planets as well as some dwarf planets and comets. Akatsuki is at Venus, several rovers and orbiters are at Mars, the Juno spacecraft just reached Jupiter, […]

New 'KEM' Proposal Would Extend New Horizons Post-Pluto Mission to 2021

If approved by NASA, the KEM proposal will allow New Horizons to continue its study of the outer fringes of the Solar System until 2021, including a flyby of 2014 MU69. Image Credit: NASA/JHUAPL/SwRI

The New Horizons mission has revolutionized our understanding of Pluto and its moons, after conducting the first-ever flyby last summer. […]

The 'Floating Hills' of Pluto: Icebergs In a Frozen Nitrogen Sea

Pluto is a tiny world and incredibly distant from the Sun, so it was a pleasant surprise for scientists last summer when […]

Pluto's Large Nitrogen Ice 'Sea' Probably Formed from Giant Impact, Scientists Say

Instead of being little more than a frozen and unchanging rocky iceball, Pluto has been revealed to be a complex and dynamic little world, with mountains, valleys, vast […]

Cassini Prepares for Last Epic Flyby of Saturn's Ocean Moon Enceladus
