SPP 1385:  The first 10 Million Years of the Solar System - A Planetary Materials Approach

• Subject Area: Geosciences ; Physics
• Term: from 2010 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 72844840

Our solar system formed 4.6 Ga ago from a collapsing cloud of interstellar gas and dust. Questions about the very origin of our Earth and planets - and the prospect of detecting Earth-like, potentially life-harbouring planets - are of tremendous public and scientific interest. The most important and critical step in building the Earth and other planets was probably the coalescence of planetesimals out of dust in the first few million years of our solar system’s existence.
The mechanisms and rates involved in this step can be revealed by analysing material left over from this growth process and accessible as meteorites or cometary dust samples returned by the STARDUST mission. The Priority Programme aims to initiate and provide the means for comprehensive and interdisciplinary studies on key aspects of planetesimal formation in the early solar system. The Priority Programme is particularly timely due to the new research opportunities provided by the availability of extraterrestrial materials and new analytical technology, combined with a dramatic increase in planned space missions by nations around the world.
The Priority Programme will crosslink both established and young research groups and will provide training and education opportunities for promising young scientists. The research is of national strategic importance, as it will maintain our national capability of analysing extraterrestrial material from future sample return missions.
