NASA ends financial support for planetary-science advisory groups amid advisory-structure drawdown NASA will end financial support for several planetary-science advisory groups as part of a broader drawdown of the agency’s advisory structure. The move withdraws funded, independent panels that advise on planetary missions and scientific priorities, reducing formal external input into NASA’s decision-making.

Plume sampling could reveal Enceladus' ocean pH and habitability A Japanese research team proposes new methods to sample Enceladus' plume material remotely to estimate the pH of its subsurface ocean without landing. The approach aims to deliver more accurate chemical constraints on ocean composition and assess the moon's potential habitability for life as we know it.

Vast's Haven-1 enters assembly and integration as first commercial space station nears launch Vast's Haven-1, promoted as the world's first commercial space station, has entered assembly and integration ahead of a planned launch. The company says it has “a very strong incentive” to fly a crew as soon as it can be done safely, positioning Haven-1 as a step toward continuous human presence in LEO.

Study defines observational requirements for Habitable Worlds Observatory biosignature interpretation A team led by NASA research biologist Niki Parenteau has posted a pre-print on arXiv that spells out the specific observational and contextual data needed to interpret potential biosignatures from the proposed Habitable Worlds Observatory. The paper identifies which measurements must accompany HWO spectra to avoid misinterpretation.

JWST finds young galaxies 'age rapidly', upending early galaxy growth models Using the James Webb Space Telescope, astronomers have found young galaxies that evolve far faster than cosmological models predict — “like seeing 2‑year‑old children act like teenagers.” The discovery provides new constraints on early star formation, planet formation and the Milky Way's assembly.
