Накратко на български

Хидрологичните процеси на Марс се анализират чрез сателитни снимки и модели, за да се разбере как са се образували сложните канали от вода. Това помага да се оцени възможността за минал живот и да се планират бъдещи мисии на планетата.

Hydrological processes on late Mars: water under the telescope and under the microscope

The aim of this project is to reconstruct paleo-hydrological conditions on Mars and to recreate the hydrogeological cycle that created the complex channel systems found on Mars’ surface. To determine the lithological and fluid characteristics and their possible related deposits, water source triggering mechanisms, and if their origin is by impact or spin axis / obliquity changes. Such a study is vital, for it addresses key questions about past Martian habitability and potential landing site of future robotic/human missions and climate. The interdisciplinary aspects of this study, such as close integration of surface geology from satellite imagery, analog modelling, and numerical modelling studies, will provide significant new knowledge of Mars environment. Understanding water on Mars is vital to assess the planet’s potential for the emergence of life and for providing usable resources for future human exploration, which is planned for 2030s. Space exploration is a sector of strategic political importance for the EU and a hallmark of international cooperation. The Commission supports several research activities related to space exploration through Horizon 2020. This project focus on characterization, modelling and analysis of several Martian channels systems, first detected on Mars in NASA CTX and HiRISE images. This project investigates ‘under the telescope’ of imagery and model ‘under the microscope’ the triggering mechanism of water source released, the environmental conditions, the lithology, hydrology and the possible related deposits. The overall objective of this project is to resolve outstanding questions about triggers, mechanisms and resulting geology of fluid water events on Mars, which may change our views on astrobiological potential and exploration. The main objectives are to identify fluid dynamics/processes and related deposits of Mars channel systems in the northern and southern hemispheres and to determine the trigger mechanism, to model Martian channel systems dynamic/processes depending on physical parameters and fluid dynamics such as lithology, clastic sediments (gravel, sand, silt), fluvial flows.

Цел на проекта

Mars displays clear evidence of water, having regions where water flowed at several times in its 4 billion years history. The aim of this fellowship is to reconstruct paleo-hydrological conditions on late Mars (from 3Ga to date) and to recreate the hydrogeological cycle that created the complex channel systems found on Mars’ surface. The stream tables, the Earth Simulation Lab and numerical modelling at the UU will allow for the first time: 1) to simulate frozen Martian subsoil characteristic and conditions; 2) to seek out signature of melting ice as sources up front of Martian river systems; 3) to investigate together the role of thermal and mechanical erosion. I will determine the lithological and fluid characteristics and their possible related deposits, water source triggering mechanisms, and will explain if it is by impact or spin axis / obliquity changes. High-resolution digital elevation modelling will be used to constrain hydrogeological parameters (under the telescope). Laboratory experiments and numerical modelling using a streamtable and an Earth Simulation Laboratory will support the core task (under the microscope). This research is urgently needed as it addresses key questions about past Martian habitability and its implications in subsurface degassing, potential landing site of future robotic/human missions and climate. The inter-disciplinary perspective adopted in this study, close integration of surface geology, analog modelling, and numerical modelling studies, will provide important new knowledge on the late Mars environment. The Experienced Researcher (ER) will work in the world-leading “River and delta morphodynamics group” group in the Department of Physical Geography at Utrecht University. The ER is already proving himself as a future leader: he has published five peer-reviewed papers, and led international teams on fluvio-lacustrine features and climate conditions and erosion rates on early Mars.
