6. Weekly Space Traffic Report (11:34–17:13)

Narrated by Alicia Siegel (NASASpaceflight.com), this segment summarizes global launches and notable missions:

• Key Launches:

  • China: Changzheng 4C and 6A launches; mysterious Xi' An 28B satellites and SatNet internet constellation.
  • United States:
    • Starlink launch from Vandenberg, marking 100th Falcon 9 launch of the year and surpassing 9,400 Starlink satellites in orbit.
    • Falcon 9 launches Boeing X-37B for its 8th mission; booster B1092 successfully lands.
  • Baikonur, Kazakhstan:
    • Soyuz 2.1B launches the Russian Bion M2 mission: a science capsule with 75 mice (some genetically altered for radiation study) and 1,000 flies.
  • Russia:
    • Angara 1.2 from Plesetsk carries classified Ministry of Defense payloads.
  • China:
    • Lijian One (Kinetica 1) launches with mixed payloads, including Mexico’s tiny Thumbsat test satellites.

7. Tech Spotlight: Space-Based Solar Power (SBSP) (17:58–20:55)

• Host’s Reflection:

  • Space-based solar power—long an “improbable dream,” but potentially transformative.
  • A recent King’s College London report: If realized by 2050, SBSP could reduce Europe’s terrestrial renewable energy needs by 80%, system costs by 15%, and battery use by two-thirds.
  • Caveats: Massive infrastructure would be required in just 25 years, alongside significant investments.
  • SBSP's strategic importance for future energy and net-zero goals is emphasized.

  Notable Quote:
  “SBSP is a tech that should absolutely factor into future models about power generation. It’s not such an impossible dream.”
