Space-station log documents Menon’s vein and blood measurements
NASA’s September 28 account records jugular-vein scans, blood-pressure readings and a red-cell count. It publishes no measurement values or clinical findings.

NASA releases Roman’s international ground-station test results
The September 25 report attributes successful data reception to stations in Japan, the United States and Australia; the tests took place September 7–17.
Solar science
Aditya-L1 spectra suggest cooling behind delayed solar glow
A September 24 paper connects the green-line signal to a flare’s late emission, but its cooling interpretation needs tests across more events.
Science
Radio study localizes auroral emission to Beta Pictoris b
The September 15 preprint infers a strong magnetic field from MeerKAT observations; the result has not been peer reviewed.
Space science
NASA station update documents Menon’s immune-study sample processing
The agency describes incubation, separation and freezing of blood samples on September 24. Analysis is still to follow; no clinical result is announced.
Space science
WMO publishes assessments of gaps in climate observation data
The findings span ground networks, satellite-data use and local needs; one assessment remains interim.
Science
XRISM spectra trace stellar wind falling toward a pulsar
A September 18 study identifies iron-line shifts in a 2025 observation of BP Crucis; the changing shape of the inflow remains an interpretation.

Science Advances papers document rare 2024 lunar impact
NASA's Lunar Reconnaissance Orbiter later identified the 222-metre McGetchin crater in before-and-after images; the papers concern that finding, not a newly observed impact.
Earth observation
FLEX and Sentinel-3C launch together on Vega-C
The two Earth-observation satellites established ground contact after their September 15 launch; Sentinel-3C must complete commissioning before adding to Copernicus's worldwide data service.

Roman’s Wide Field Instrument activates during commissioning
NASA’s September 15 update says Roman’s primary infrared camera has begun checkout and its Coronagraph Instrument has passed an initial systems test; neither step starts science operations.
Planetary science
Mercury contraction may be underestimated by up to 30%, study finds
The authors found fewer mapped shortening features in rough terrain and use that pattern to revise estimates of the planet's cooling-driven contraction.
Solar science
Aditya-L1 study traces small brightenings before major solar flares
Seven 2024 flare cases contained 102 ultraviolet transients before onset, but the observations do not yet establish a flare-forecasting method.
