Накратко на български

Вътрешната структура, магнитното поле и възрастта на повърхността на Меркурий се анализират чрез нови лабораторни данни и термични модели. Това помага за по-доброто разбиране на еволюцията на планетата и начина, по който се формират земноподобните планети.

Refining our view on planet Mercury, in anticipation for the BepiColombo mission.

This fellowship is devoted to refining knowledge of planet Mercury, and prepare scientific model development and laboratory data for interpretation of upcoming measurements by ESA’s BepiColombo space mission (launched in 2018, entering Mercury-orbit in 2025). The objective is to improve constraints on Mercury’s evolution and interior structure from available, new, and upcoming data, and contribute to the understanding of planet formation and magnetic field generation in terrestrial planetary cores. An interdisciplinary approach is taken that involves improving methods for studying the generation of Mercury’s magnetic field, improving constraints on Mercury’s interior from geophysical and new experimental data, and improving Mercury’s surface chronology which defines constraints on Mercury’s evolution. A detailed thermal evolution model is developed, currently the best available tool for studying Mercury’s thermal evolution and long-term dynamo forcing. New experimental high-pressure data on metallic alloys have been obtained and integrated in interior structure models of planet Mercury, which examine the potential of geodetic measurements by BepiColombo to constrain the composition of Mercury’s core and mantle. An improved crater production function for estimating the formation age of Mercury’s surface is developed, but requires additional development.

Цел на проекта

As the inner-most object of our solar system, planet Mercury is of unique relevance for e.g., solar system dynamics, planetary formation theory, and terrestrial magnetic field generation. So far, two single (NASA) space missions to Mercury have been performed. In 2018, ESA and JAXA will launch the dual-satellite BepiColombo to study Mercury from orbit with the largest and most advanced payload to date. BepiColombo’s formal objectives have been formulated prior to NASA’s latest space mission to Mercury (MESSENGER). It is now time to use MESSENGER's data return to refine our view on Mercury as support for BepiColombo’s measurement phase, starting December 2025.In this fellowship, MESSENGER data will be used to re-investigate Mercury’s interior structure, magnetic field and surface age. At the Royal Observatory of Belgium, advanced core-composition specific models on the planet’s interior will be developed. These will incorporate new experimental data on relevant metallic core-alloys which will be obtained at the High-Pressure laboratory of the VU University in Amsterdam and at synchrotron facilities. The potential of future geophysical measurements to constrain Mercury’s core composition will be the emphasize of these models.Dynamo simulations will be performed at the Max Planck Institute for Solar System Research to study Mercury’s magnetic field generation for a suite of dynamo constraints. These will improve constraints on the core’s dynamic state, which relates to the planet’s structure and core composition.Also, a new crater-counting-based surface dating method will be developed and calibrated by new models for the inner solar system’s dynamics. Applied to Mercury, this method will refine its surface age and its geological evolution and informs on the evolution and state of its mantle. Results of the above topics will be discussed in light of the measurement potential of BepiColombo and other future space missions and in light of the planet’s formation.
