Il faudrait vraiment analyser l'origine de ce courant de pensée qui prétend que «rafraîchir son logement quand il fait trop chaud dehors» est un luxe frivole et un gâchis d'énergie, alors que PERSONNE ne le pense pour «réchauffer son logement quand il fait trop froid dehors».

New article from the researchers at the Instituto de Astrofísica e Ciências do Espaço (IA) 👀
IA's Pedro Machado is an Ariel Consortium board member & coordinator of the Ariel working group linking the study of exoplanet atmospheres with that of the Solar System
ALT Screen capture of the first page of research article 'Transmission Spectroscopy Along the Transit of Venus: A Proxy for Exoplanets Atmospheric Characterization'. A link to this article is in the next tweet of this thread.
À l'Observatoire de Haute Provence avec les étudiant•es de M2 du stage #SIMO, on jongle entre les nuages pour regarder des planètes !
Petits détails techniques/scientifiques :
* Les images sont en fausses couleurs (B = filtre vert; V = filtre rouge ; R = filtre infrarouge)
* On voit bien les 4 satellites de Jupiter tous du même côté (ainsi que les défauts d'alignement résiduels entre les canaux RVB) ;

Highlight from the future missions concept was the very loud video of the Tumbleweed Mars rover prototype

@LesiaAstro @Obs_Paris recherche un profil d'ingénieur en développement logiciel pour les moyens de tests de l'instrument VenSpec-U. Il s'agit d'un des instruments qui équipera la sonde #Envision de l'@esa pour l'exploration de la planète Vénus en 2030+. lesia.obspm.fr/-Emplois-stag…

This is definitely still in a lot of intro textbooks but … planetary scientists no longer see a lead connection between a planetary magnetic field and long-term atmosphere persistance.
Mars lost its atmo because it’s small.

I encountered a delightful little astrodynamics proof last week when an astronaut casually stated it as a fact, and when I looked skeptical, he just smiled and said, "Check it yourself."
Here's the statement:
"It takes 2 hours to orbit at the surface of any object made of rock"
Thanks #EPSC24 for reminding us on your submission portal that we are all mortal beings... Feature request: "Presenting author" and "Deceased" tick boxes should be mutually exclusive :-D

Ever wanted to dive deep into the #EnVisionMission and all its details?
Then have a look at the EnVision Study Definition Report, also known as the Redbook.

This 175-page comprehensive document has just been published with the EnVision adoption by @esa.

La mission EnVision qui ira étudier la planète Vénus en 2031 a définitivement été adopté par @esa. @LesiaAstro @Obs_Paris est impliqué dans la fourniture des spectrographes VenSpec-U et VenSpec-M qui observeront la surface et l'atmosphère de Vénus en UV et en proche IR.

It’s official, I have been adopted! Time to celebrate!
📢 @ESA adopts two ambitious space science missions: Venus voyager #EnVision and gravitational wave surfer #LISA.
“These trailblazing missions will take us to the next level in two extraordinarily exciting areas of space science and keep European researchers at the forefront of these domains,” says ESA Director of Science @CGMundell
The ‘adoption’ step recognises that the missions' concept and technology are sufficiently advanced, and gives the go-ahead to build the instruments and spacecraft. Both spacecraft are planned to launch with an #Ariane6

Best news to close the @envisionvenus VenSpec suite meeting at @MPSGoettingen !
ESA - We're heading for Venus: ESA approves EnVision esa.int/Science_Exploration/…

Another great VenSpec suite face-to-face meeting. While we do most of our work remotely using collaborative tools, nothing beats a good discussion over coffee/tea/beer/water... So we keep our tradition of quarterly meetings. Thank you
@MPSGoettingen
for hosting us this week.
Kick-off of the #VenSpec Suite Meeting at #MPSGoettingen! Hope you enjoy a week of talks, discussions & more. VenSpec will travel to #Venus on @esa’s mission #EnVision to study the planet’s surface, clouds, atmosphere. @envisionvenus @DLR_en @latmos_ipsl @iaa_csic @BIRA_IASB
