MTG-S1 and Sentinel-4 launch to change how we see our atmosphere: #MTGS1 satellite has been designed to generate a completely new type of data product, especially suited to nowcasting rapidly evolving storms, with three-dimensional views of the atmosphere, while Copernicus Sentinel-4, which consists of an instrument mounted on the MTG-S1 satellite, will be the first mission to monitor European air quality from geostationary orbit.

If the #Crew11 launch goes ahead today at 15:43 UTC (webcast on https://www.youtube.com/watch?v=k0ILMhbWHNQ from 11:35 UTC) there will be a post-launch press conference at 17:00 UTC with Dmitry Bakanov, the director general of Roscosmos, on the panel: https://www.nasa.gov/news-release/nasa-sets-coverage-for-agencys-spacex-crew-11-launch-docking/ (updated) - must have been a looong time that a Russian space boss was featured that prominently by NASA.

T CrB - overview of the accretion history, Roche-lobe filling, orbital solution, and radiative modeling: #TCrB are mounting, initiated by the discovery in 2015 of a new enhanced mass-transfer phase (SAP), which is reminiscent of the one preceding the last recorded outburst in 1946. [...] SAP has been caused by an inside-out collapse of the disk, during which the mean accretion rate onto the WD has been ~28x larger than in quiescence. SAP ended in April 2023, but from May 2024 mass-flow has intensively resumed at disk inner radii while the collapse wave reached the outer portions of the disk; the consequent revamp in mass accretion could fill the gap inherited by the fainter 2015-2023 SAP and eventually lead the WD accreted shell to ignition."

The underground “Jiangmen Underground #Neutrino Observatory" (JUNO) near Jiangmen city in the Guangdong Province has successfully completed the filling of its 20,000 tons of liquid scintillator and begun data taking: https://www.prisma.uni-mainz.de/outreach/press-releases/juno-completed-liquid-filling-and-begins-data-taking/ - JUNO will tackle one of this decade’s major open questions in particle physics, the ordering of neutrino masses i.e. whether the third mass state (ν₃) is heavier than the second (ν₂).
