Projects


Pathways to Habitability PatH

This project started in 2012, initially for a duration of four years, has been funded and prolongated in 2016 by the FWF for an other four years. The main purpose is to address astrophysical conditions for a planet to be able to develop any form of life. Several subprojects dealing with protoplanetary disks (SP2), transport of water molecules (SP3), properties of stars (SP4), magnetospheres (SP6), planetary atmospheres and loss of volatiles (SP7), and binary star systems (SP8). I am currently a postdoctoral researcher since 2013 in the SP8 subproject lead by Dr. Elke Pilat-Lohinger. The project PatH is supervised by Univ. Prof. Manuel Güdel.


NEOShield

NEOShield is a project involving European scientists. It aims to study in details different possible and realistic options to mitigate the collision of a near-Earth asteroid with the Earth in the future (near, mid and long term) via several technics (i.e. gravity tractor, nuclear blast or kinetic impactor). A key criteria for the success of such a mission is the orbital accuracy of the asteroids based on different types of observations (radar, optical and radio science). As a member of the NEOShield advisory board during the first period of the project, I brought my expertise on orbital accuracy and error propagation of asteroids' orbit.


PôDET

PôDET (PÔle sur la Dynamique de l'Environnement Terrestre) is a project developed at IMCCE, Paris Observatory, this project aims to be a monitoring system to track objects (space debris, meteor and near-Earth objects) in the Earth neighbourhood and provide online informations and tools for the public. I was regularly invited as a consultant to develop the near-Earth segment.


VESPA/Europlanet 2020

VESPA (Virtual European Solar and Planetary Access) is an activity in the Europlanet 2020 Research Infrastructure programme funded under the European Commission’s Horizon 2020 programme. It aims at building a Virtual Observatory for Planetary Science, connecting all sorts of data in the field, and providing modern tools to retrieve, cross-correlate, and display data and results of scientific analyses. VESPA is a common activity from 17 institutes in Europe, open to contributions from the community. I was a scientific consultant for this project and brought my expertise on orbit determination, MOID and database developement.


Orbit Propagation algorithms for the Space Situational Awareness

In 2012, IMCCE and Astos Solutions developed a module called NEOProp in the context of the Space Situational Awareness program (SSA) of ESA and funding by ESA after an invitation to tender. The main purpose was to bring new approaches for impact risk assessment, develop and implement new algorithms and deliver a software for near-Earth orbit propagator. For this project, I was Co-I of the proposal and as a postdoc, I was in charge of several work packages. At the end of the project, a prototype software was delivered to ESA together with several technical reports and ended in April 2013 with a final presentation at ESTEC (Noordwijk, Netherlands).


The APEX Mission

The Apophis Express (ApEx) project is a prototype mission initiated by the CNES and involving several french laboratories (LESIA, LAM, IMCCE, CNES, OCA). It aims to design a space mission for a rendez-vous between a probe and the asteroids (99942) Apophis. I was a scientific consultant for this project and brought my expertise on orbital accuracy, orbit propagation and modelling of non-gravitational effect (Yarkovsky effect)


Asteroid Ephemerides

Asteroid Ephemerides was part of the Space Situational Awareness program (SSA) of ESA and funded by ESA after an invitation to tender. The main purpose was one hand to compare informations from the two main asteroid databases, Astorb and the Minor Planet Center (MPC), and on the other hand, to establish a road map to design short and long term missions to asteroids. The two databases investigated for this purpose were astorb and MPC. For this project, I was Co-I and was work package leader and manager. The project ended in March 2011 with the delivery of a scientific report (summary) an a final presentation at ESOC (Darmstadt, Germany)
