2. Gender in EU project

Author

Dehant V.

Abstract

In EU project (being H2020 or ERC), we are asked to do a “Gender Equality Plan” and to take care about gender issues. I think that this is very important. We definitely need to take care about gender at recruitment level and to take care about gender balance. However, to care about gender inequality does not only refer to gender balance in the teams in charge of carrying out the projects but also to plan research and innovation activities with the goal of inspiring a new generation of women in space. Gender dimension brings a vision that goes beyond the line of sight. It is not only about statistics on the number of male and female researchers in a specific field or gender balance in the Consortium but here are some paths to follow: (1) becoming gender-sensitive, (2) integrating an in-depth understanding of both genders’ needs, behaviours, and attitudes, (3) promoting our sector to young girls at the level of schools or universities, and (4) being aware about unconscious gender biases. Gender bias is the tendency to prefer one gender over another gender. Several studies found that both men and women prefer male job candidates. So much so that, in general, I have found on the web that a man is 1.5 times more likely to be hired than a woman when both are equal-performing candidates. Bias is a systemic prejudice for, or against something or someone, based on for instance stereotypes. When preparing newsletters for my EU project about that, I came through several examples about ways in which women and men are often held to different standards in the workplace. I think that this is interesting to know. This is what I propose to share with you.

Abstract

We present the scientific case for inclusion of penetrators into the Europan surface, and the candidate instruments which could significantly enhance the scientific return of the joint ESA/NASA Europa-Jupiter System Mission (EJSM). Moreover, a surface element would provide an exciting and inspirational mission highlight which would encourage public and political support for the mission. Whilst many of the EJSM science goals can be achieved from the proposed orbital platform, only surface elements can provide key exploration capabilities including direct chemical sampling and associated astrobiological material detection, and sensitive habitability determination. A targeted landing site of upwelled material could provide access to potential biological material originating from deep beneath the ice. Penetrators can also enable more capable geophysical investigations of Europa (and Ganymede) interior body structures, mineralogy, mechanical, magnetic, electrical and thermal properties. They would provide ground truth, not just for the orbital observations of Europa, but could also improve confidence of interpretation of observations of the other Jovian moons. Additionally, penetrators on both Europa and Ganymede, would allow valuable comparison of these worlds, and gather significant information relevant to future landed missions. The advocated low mass penetrators also offer a comparatively low cost method of achieving these important science goals. A payload of two penetrators is proposed to provide redundancy, and improve scientific return, including enhanced networked seismometer performance and diversity of sampled regions. We also describe the associated candidate instruments, penetrator system architecture, and technical challenges for such penetrators, and include their current status and future development plans.

Abstract

The Second-generation Louvain-la-Neuve Ice-ocean Model (SLIM, www.climate.be/slim_flyer) deals with the equations governing sea-ice, geophysical, environmental and groundwater phenomena by means of the (discontinuous Galerkin) finite element method on 1D, 2D or 3D unstructured meshes. To take advantage of state-of-the-art developments, SLIM is also being interfaced with existing tools (often based on radically different numerical methods), such as the well-known and widely used General Ocean Turbulence Model (www.gotm.net, GOTM). The post-processing of the results is achieved with the help of usual statistical and computer graphics methods. Other techniques are also resorted to, such as tracer and timescale methods derived from CART (Constituent-oriented Age and Residence time Theory, www.climate.be/cart) or network science tools (sites.uclouvain.be/networks) (Thomas et al. 2014).The hydrodynamics simulated by the aforementioned finite element model can be introduced into a number of SLIM-based environmental modules, which are capable of representing sediment transport (Delandmeter et al. 2015), as well as the fate of some classes of contaminants, namely microbiological pollutants (de Brauwere et al. 2014), endocrine disrupting compounds, heavy metals (Elskens et al. 2014) or radionuclides. A simple ecological model is being developed, whose aim is to simulate the evolution of various species of phyto- and zoo-plankton (Naithani et al. 2016).

Abstract

International audience; If the apparition of life is maybe a rapid process on a habitable planet, the evolution of life toward intelligence is a much longer process and about 4000 Myears were needed on the Earth. What is the probability for a telluric planet to offer the right conditions to life evolution? Why is the Earth the only planet on the Solar System where liquid water was able to be maintained liquid at the surface, and why Mars and Venus were unable to maintain such temperature conditions? What is the level of volcanic ac- tivity on Mars? What is the heat flow and its impact on the temperature gradient in the subsurface? How can we extrapolate this activity in the past and estimate the im- portance of volcanic degazing and its impact on the early atmosphere?Do we have indications for an early plate tectonics regime on Mars with a water rich upper mantle and how im- portant is such a regime in the habitability of planets? Why and when stopped the Martian dynamo? All these scientific questions, which impact on the Martian long term habitability, are related to the geodynamics of the planet and its geological evolution and activity. In order to provide an answer, we need to understand how a tel- luric planet is geologically evolving, which needs a detailed knowledge of its interior structure, of the mineralogy and temperature of its mantle, of the amount of energy re- leased during accretion and therefore of the size of the main units of the planet (crust, mantle, core), of the heat flux and possibly of the long scale convective structure. We also need to monitor its present geological activity. The Long Lived Geoscience Observatory on Mars will setup a permanent network of fixed stations on the planet, op-erating for a decade or more. These stations will moni- tor with high resolution the magnetic field, the rotation and the seismic activity of the planets, will measure the heat flux and will in addition monitor the present envi- ronment (meteorology, radiations, ionospheric properties, etc) and support human exploration. This suite of instru- ment will be able to perform a passive sounding of the deep and shallow planetary interior and to retrieve the temperature profile and mineralogical profile in the planet and 3D mantle lateral variation by a joint inversion of the seismic, conductivity profiles and heat flux and geodetic data. 8 stations, operating for 4 to 10 years will be nec- essary to obtain such detailed tomographic picture of the mantle convection and we can therefore expect a full de- ployment after 4 or 5 Mars windows. Such stations, com- parable to the of Autonomous Lunar Surface Experiment Package, deployed by NASA during the Apollo missions, might be deployed systematically by all the future Mars landing missions and might therefore be an original Euro- pean contribution to the International Mars exploration in the next decade and will complement with the necessary geophysical data the analysis of the future sample return missions. In addition to Roving and Sample Return mis- sion, they also can be deployed by more dedicated multi- lander missions. In addition, such stations might also be proposed to the future Moon landing missions. In both cases, these Planetary Long Lived Observatories will not only help us to better understand the formation and evo- lution of two of the Solar Systems Terrestrial Planets, but will also support human exploration by a permanent sur- vey of the planetary environment.
