[00:00:03]Joint European Chinese SMILE spacecraft prepares for Vega C launch.

[00:00:08]The SMILE mission is in final launch preparations in French Guiana.

[00:00:11]>> [music] >> It will analyze how solar wind impacts Earth's magnetic shield using global imaging.

[00:00:16]On the positive side, deepening international cooperation between Europe and China enables a comprehensive, multi-perspective approach to global space weather monitoring.

[00:00:24]>> [music] >> On the other hand, geopolitical tensions and strict technology transfer limits could complicate long-term operational management between the participating international agencies.

[00:00:36]>> [music] >> Deep space.

[00:00:37]Astronomers detect interstellar dust rain in ancient Antarctic ice. [music] Scientists found iron-60 inside Antarctic ice cores up to 80,000 years old.

[00:00:47]>> [music] >> This radioactive isotope proves Earth continuously drifts through ancient stellar explosion debris.

[00:00:52]>> [music] >> On the positive side, analyzing pristine ice sheets provides an unprecedented, continuous timeline of our solar system's journey through galactic neighborhoods.

[00:01:01]On the other [music] hand, extracting and verifying trace interstellar isotopes from deeply buried ice samples remains technically [music] challenging and resource-intensive.

[00:01:11]Commercial space.

[00:01:13]Cowboy Space files massive [music] 20,000 satellite orbital data constellation.

[00:01:18]Cowboy Space submitted FCC plans [music] for its Stampede orbital data network after securing $275 million. The The system uses modified rocket upper stages as computing platforms.

[00:01:29]>> [music] >> On the positive side, utilizing spent rocket stages as functional data hubs could maximize launch efficiency and provide low-latency orbital edge computing. [music] On the other hand, deploying 20,000 additional large satellites risks severely exacerbating low Earth orbit congestion and increasing space debris hazards.

[00:01:48]Astronomy.

[00:01:50]10-year SETI search concludes review of 70,000 stars.

[00:01:53]UCLA astronomers completed [music] a decade-long search scanning 70,000 stars for techno signatures.

[00:01:59]>> [music] >> While 100 million candidate signals were analyzed, none originated from an alien civilization.

[00:02:05]On the positive side, establishing rigorous baseline data [music] narrows down look directions and refines background interference algorithms for future interstellar hunting.

[00:02:13]On the other hand, devoting massive, multi-year observational time to narrow radio bands may miss [music] alternative or more advanced communication methods.

[00:02:24]Rocket Tech Catalyst Link [music] spacecraft passes critical testing for telescope rescue.

[00:02:29]Catalyst Space Technologies completed key testing [music] for its Link spacecraft ahead of a June launch.

[00:02:35]The mission aims to extend the lifespan of a 500 million-dollar space telescope.

[00:02:38][music] On the positive side, developing commercial in-orbit servicing capabilities saves hundreds of millions of dollars by extending the utility of active assets.

[00:02:47]On the other hand, autonomous close proximity operations carry inherent collision risks that could accidentally disable the very telescope they aim to preserve.
