Plus: astronomers find a \"mega-Earth\" 23 times more massive than our planet that shouldn't be able to exist, a star weaving impossibly close to our galaxy's supermassive black hole that could reveal its spin within a decade, and new JWST data showing the early universe's galaxies were hiding roughly four times more mass than we thought. Full show notes: Today's episode — S05E172, Thursday August 20, 2026: Main story: China's private spaceflight sector sticks the landing. On August 19, Chinese commercial launch company LandSpace successfully recovered the first stage of its Zhuque-3 (ZQ-3) rocket after liftoff from the Dongfeng Commercial Space Innovation Pilot Zone in northwestern China — the first time any Chinese commercial company has landed an orbital-class booster. The 76.6-metre, stainless-steel, methane-fueled rocket (taller than a Falcon 9) touched down on four legs roughly 390km downrange in Gansu Province about eight minutes after liftoff, running on a single Tianque-12 engine. It's ZQ-3's second flight — the first, in December 2025, reached orbit but couldn't stick the recovery. The landing puts LandSpace among a very small club of companies with proven booster-reuse technology and marks, in the company's words, a shift \"toward the engineering application phase of reusability.\" A \"mega-Earth\" that shouldn't be this dense. Astronomers led by Max Kroft (University of Wisconsin–Madison) have identified GJ 523b, a rocky exoplanet 23.5 times more massive than Earth but only 2.5 times its width — extraordinarily dense for its size. Standard planet-formation models say a planet this massive, orbiti…","meta_description":"Anna and Avery cover LandSpace becoming the first Chinese commercial company to land an orbital-class rocket booster — a big step for the country's privat…","key_points":[],"chapters":[],"topics":[],"duration_seconds":889,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/astronomy-daily-space-news-updates-5658676/episodes/landspace-nails-it-china-s-first-private-booster-recovery/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/astronomy-daily-space-news-updates-5658676/landspace-nails-it-china-s-first-private-booster-recovery.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
