[#ScienceNews on #Mars] The #ChemCam instrument installed on NASA's #Curiosity rover has identified the presence of #manganese in particularly high concentrations within #rocks that dot the floor of the #Gale crater.

This discovery shows that these #sediments were formed in a river, a delta or near the shore of an ancient lake. It raises questions about #oxydation processes on Mars... and reinforces the hypothesis of past #habitability...

[#HDR defense] of IRAP astronomer Sébastien Deheuvels this Monday morning. Topic: the #seismology of #subgiant and red giant stars.

Analysis of seismic data acquired by the #CoRoT and #Kepler space missions has enabled Sébastien Deheuvels and his team to revisit the problem of #chemical element transport and angular momentum in stars, measure the #internal rotation of sub-giants and red giants, detect the presence of #magnetic fields in stellar interiors, ...

History of [#eclipses (3/3)] From now on, there's no need to wait for the next total #Sun #eclipse and to travel the globe to observe it: the development, on the ground and in space, of #coronography - a technique invented in 1931 by Bernard Lyot - makes it possible to reproduce this celestial phenomenon.

ESA is currently developing the #Proba-3 mission, which will be capable of generating solar eclipses on the fly from space: https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Proba_Missions/ESA_s_solar_eclipse_maker_Proba-3

Looking forward to the future! 😋

Histoire [#éclipses (2/3)] Ce lundi, une éclipse totale de #Soleil se produira au-dessus du continent nord-américain. La #couronne solaire sera alors visible à l'oeil nu et devrait ressembler à l'image ci-dessous, d'après les chercheurs du Predictive Science Inc.

Ces derniers ont conçu un #modèle 3D de la couronne solaire basé sur diverses données d'observation, au sol et dans l'espace - issues notamment de la sonde #SolarOrbiter de l'ESA.

[#SpaceSuccess] Following ESA's de-icing operation, the #Euclid satellite has gained 15% in optical sensitivity!

All satellites are assembled on Earth, in clean rooms whose humidity is close to 50°C. As it is propelled into space, its various components gradually cool down... and water condenses. To encourage evaporation, radiators have been installed in Euclid's instrument bay and the mirrors of the #telescope ...

[#ScienceNews @IRAP ] In 2029, the ESA and JAXA joint #CometInterceptor mission will take off from the Kourou Space Center aboard an #Ariane6. Objective: to study a #comet in its original state - or even an object of interstellar origin.

On March 5, @IRAP delivered the functional electrical model of the Low-Energy Electron Spectrometer (1 eV-1 keV) which is part of the #DFP (Dust, Fields, Particles) experiment. The future is on the way! 👍
