🛰️ Rocket Lab launches Japan's WADATSUMI-II radar satellite (reported)
Rocket Lab's Sea God Surveys mission deployed WADATSUMI-II, a radar-observation satellite developed for Japan's iQPS.
The 4 November space-industry update reports that iQPS subsequently established initial contact with the satellite and that antenna deployment had taken place.
Calibration is expected before the satellite begins its regular observation work.
Why it matters: Radar satellites can provide Earth-observation data in conditions where conventional optical imaging is limited, including cloudy weather and darkness.

☄️ Taurid meteor shower reaches its peak period (reported)
Astronomy reporting on 4 November highlights the Taurid meteor shower, with its activity expected to be particularly noticeable around the current period.
The Taurids are associated with relatively slow-moving meteors and are known for occasional bright fireballs.
Actual visibility depends on local weather, light pollution and observing conditions.
Why it matters: The event provides an opportunity for public engagement with astronomy and observational science.

🔬 Research interest in rare particle decay continues (reported)
Science reporting on 4 November highlights new discussion of evidence involving a rare particle-decay process investigated by CERN researchers.
The development is being discussed in the context of the Zeptoverse and particle physics.
The precise experimental result, statistical significance and peer-reviewed publication details require examination of the underlying scientific paper before drawing conclusions about a confirmed discovery.
Why it matters: Rare particle interactions can help researchers investigate fundamental questions concerning matter and the forces governing particle behaviour.
