Statement on Importance of Supporting Planetary Exploration

The AAS Division for Planetary Sciences (DPS), the world’s largest organization of professional planetary scientists, today issued a statement highlighting the discoveries of highly successful planetary missions over the last decade and the importance of supporting ongoing and future missions in light of recent budgetary discussions within NASA including the James Webb Space Telescope.

The DPS leadership stressed the importance of following the priorities identified by the planetary sciences community in the decadal survey (“Vision and Voyages”) that laid out a prioritized plan for solar system exploration from 2013 to 2022.

Our solar system, where planets have a range of sizes and move in near-circular paths, may be rather unusual, according to a German-British team led by Professor Pavel Kroupa of the University of Bonn. The astronomers, who publish their model in the journal Monthly Notices of the Royal Astronomical Society, find that forming planetary systems may be knocked around by crashes with nearby clumps of material, leading to systems where planets have highly inclined orbits and where the smaller (and potentially habitable) worlds are thrown out completely.
