NASA Unveils Design for Message Heading to Jupiter’s Moon Europa
The moon shows strong evidence of an ocean under its icy crust, with more than twice the amount of water of all of Earth’s oceans combined. A triangular metal plate on the spacecraft will honor that connection to Earth in several ways.
"New research suggests there’s less oxygen on the icy surface of Jupiter’s moon Europa than thought — and that could affect what if any life might be lurking in the moon’s underground ocean."
#STERNFREUNDE BEOBACHTUNGSTIPP: MERKUR, JUPITER + ISS am Abendhimmel. In der Abenddämmerung zwischen dem 19. bis 29. März erscheint der flinke #Merkur ab ca. 19.00 Uhr in bester Abendsichtbarkeit über dem Westhorizont, um dort schon bald mit Eintritt der Dunkelheit wieder unterzugehen. Am 22. März steigt dazu um 21.17 Uhr die #ISS (die Einhaltung der aktuellen Flugplanung vorausgesetzt) vom Horizont auf und fliegt scheinbar nah am verbliebenen Planeten #Jupiter vorbei über den Abendhimmel.
Soirée [#GrandPublic] Ce mardi soir, Nicolas André, chercheur au @cnrs et planétologue à l' @IRAP, spécialiste des environnements planétaires impliqué dans de nombreuses missions spatiales, présentera la mission #JUICE dédiée à l'étude de la planète #Jupiter et de ses lunes glacées.

Think scientists know how planets are formed? New simulations show large planets that form far away from their host stars start their lives more like a flattened disk — a shape called an oblate spheroid. Earth, we know, is not flat. But Jupiter may have once been. Here’s more from Science Alert on how the formation of planets might not always go the way we picture in our heads. https://flip.it/GP-ns6 #Science#Planets#Space#Jupiter
The Jupiter moon Io - captured by the Juno spacecraft during Perijove 58.
The angle of the sun during this flyby created stunning specular reflections on the basalt covered lava lake of Loki Patera.
🛰️🟡 Ce 3 février, la sonde #Juno de la NASA a effectué un nouveau survol de la lune #Io de #Jupiter à une distance au plus près de 1500 km.
Voici l'une des premières images acheminées vers la Terre montrant la surface de la lune volcanique :

The tent around the spacecraft was erected to support electromagnetic testing. Set to launch from Kennedy Space Center in Florida in October, Europa Clipper will arrive at the Jupiter system in 2030 and conduct about 50 flybys of the moon Europa. Credit: NASA/JPL-Caltech
