Offres de position post-doctorale pour InSight en France
NASA InSight mission has landed on Mars in late 2018 and is sending back since February high quality seismic and meteorological data, including 20 sample per seconds 3 axis Very Broad Band (VBB) ground velocity data and 10 sample per second pressure data.
In the frame of the Agence Nationale de la Recherche MAGIS project (MArs Geophysics with InSight) and with the support of the French Space Agency, CNES, 5 postdoc positions are open in France in Planetary seismology, Planetary atmospheric Science, Planetary acoustic and high pressure/mineralogy :
Postdoc at Toulouse ISAE-SUPAERO
She/He will participate to the analysis, understanding and inversion of the recorded ground deformation related to atmospheric pressure waves and variations. The analysis of the first set of INSIGHT records clearly demonstrates that these data are capable of providing new constraints on Mars atmosphere physics.
Postdoc at Toulouse IRAP
The goal of the postdoc project is measure the elastic parameters and the sound velocities (Vp, Vs) of minerals candidate for Mars' mantle. The final goal is the estimation of the mineralogical composition of the mantle of Mars from the Mars Insight SEIS data. He/She will perform high-pressure high-temperature experiments in conjunction with synchrotron X-ray radiation and ultrasonic interferometry.
Postdoc position in Paris at Laboratoire de Météorologie Dynamique (LMD)
She/He will carry out research aiming at characterizing the meteorological signals at all spatial and temporal scales, as recorded by InSight’s weather station or seismometers. For the local turbulent scale, Large Eddy Simulations will be used in order to approach the upper frequency of measurements and to study the complete turbulent spectrum on Mars.
Postdoc position in Nice at Lagrange-Observatoire de Nice
One of the key objectives of the InSight mission is to constrain how the crust of Mars formed and evolved over time, from the initial differentiation of the planet to subsequent modification by magmatic and impact processes. From seismic measurements, the InSight mission will provide definitive information about the deep structure of the crust of Mars. We expect to determine the crustal thickness at the InSight landing, to detect any large-scale layering that might be present within the crust, and to quantify scattering processes that may be a result of impact fracturing of the crust.
Postdoc position in Paris at Institut de Physique du Globe de Paris (IPGP)
After more than one year of operation, the InSight mission has now recorded several hundred of events and has collected long time series for the 6 seismic channels and pressure/wind channels. These data sets enable now systematic data analysis, enabling stack/cross-correlation on both events and noise and enhancement of the signal to noise thanks to pressure decorrelation and other noise correction technics.
The duration of the contracts varies from 15 months to 24 months and can start on April 1st. Salary follows French university standards and depends on the research experience since the PhD defense. All basic insurance benefits are provided. Applicants should send a cover letter, curriculum vitae, statement of research interests and contact information for a minimum of two references. See additional details for each application.
Application received by February, 20th, will be considered for the first selection process, but the positions will remain open until filled.
Design and development of a new generation of planetary seismometers with extremely high performances based on the use of an interferometric readout
In the framework of Pioneers (Planetary Instruments based on Optical technologies for an iNnovative European Exploration using Rotational Seismology), an European Union H2020 program project, IPGP is developing a new generation of seismometers targeting very high performances (self-noise of a few 10-11 m.s-2/sqrt(Hz ) to address the Moon seismology science objective and other missions needing ultra-sensitive accelerometers. IPGP is responsible for the development of a translation seismic sensor, in partnership with iXBlue (a French leading company specialized in optronic and Fiber Optics Gyroscopes), who will develop its optical readout.
Application deadline : February, 20th, 2020.
