Colonization of the outer Solar System Colonization of the outer Solar System Many parts of the outer Solar System have been considered for possible future colonization. Most of the larger moons of the outer planets contain water ice, liquid water, and organic compounds that might be useful for sustaining human life. Colonies in the outer Solar System could also serve as centers for long-term investigation of the planet and the other moons. In particular, robotic devices could be controlled by humans without the very long time delays incurred in communicating with Earth. There have also been proposals to place robotic aerostats in the upper atmospheres of
The Planets five then-known dwarf planets, Eris, Pluto, Haumea, Makemake, and Ceres. Unlike Matthews' composition, this work is not intended to be incorporated into a performance of Holst's suite. In 2006, the Berlin Philharmonic, with Sir Simon Rattle and EMI Classics, commissioned four composers (Kaija Saariaho, Matthias Pintscher, Mark-Anthony Turnage, and Brett Dean) and recorded an additional, four-movement suite based on asteroids in the Solar System.
