TRR 170 & NASA's InSight Mission
On November 26 2018, NASA has successfully deployed the InSight (short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander on Mars. For the next two years, the probe will collect geophysical data to study interior properties such as heat transport and earthquakes generated by material transport in the red planet and meteorite impacts. The Institute for Planetary Research at DLR in Berlin is in charge of the heat flow probe in this mission. One of the big goals of the project will be to test existing models of the interior structure of Mars such as its crustal thickness, mineral transformations in the Martian mantle and the size and composition of the Martian core.
In particular core composition and the temperature structure of the Martian interior are controversial. Recently, TRR 170 researchers studied concentrations of sulfur and related elements in Martian meteorites and inferred that the Martian mantle should contain a lower amount of sulfur than previously thought (Wang and Becker, 2017, Earth and Planetary Science Letters, v. 463, 56-68). This result also implies a considerably lower sulfur content in the Martian core of about 5 to 10 weight-%, compared to previous estimates of 15 to 20 weight-%. InSight’s goal will be to collect data that can be used to test these different hypotheses and to assess if the Martian core is fully molten or partially solid like Earth’s core. From these studies, we will learn more about the formation and early evolution of Earth-like planets and the influence of geological processes on planetary habitability.

The I, Scientist Conference, in Berlin Adlershof (Aug 25 - 26, 2018) focused on female role models in- and outside of academia.
Markus Patzek, PhD student at the Institute of Planetologie (University of Münster, Germany) received the Brian Mason Award (1,500 $) for his abstract presented at the Annual Meeting of the Meteoritical Society in Moscow (July 22 – 27, 2018).
This award honors young PhD students and is sponsored by the “Meteorite Times Magazine” and the „International Meteorite Collectors Association (IMCA)“. Markus reports the discovery of volatile-rich fragments in brecciated meteorites that are different in their mineralogical and isotopical composition from CI chondrites. This result indicates a larger variability of primitive CI-like material in the early Solar System 4.5 billion years ago. The new discovered fragments are important to understand the composition of building blocks of terrestrial planets.

The European Planetary Science Congress 2018 will take place at the TU Berlin, Berlin, Germany,
Sep 16–21, 2018.
This attractive location provides a platform to exchange and present results, develop new ideas and to network amongst the worldwide planetary sciences community. It will have a distinctively interactive style, with an extensive mix of talks, workshops and posters, intended to provide a stimulating environment for the community to meet. The meeting will cover the entire scope of the planetary sciences.
We look forward to seeing you there.
Aims & scope
The intention of the European Planetary Science Congress 2018 is to cover a broad area of science topics related to planetary science and planetary missions. The programme of the congress will contain oral and poster sessions, and it will emphasize workshops and panel discussions in order to have a strong interaction between the participants.
