This Week in Space Tech #19

Welcome to This Week in Space Tech, covering Dec 22 to Dec 28, 2025. Here are the developments that mattered across space technology and space startups. ## Launches and flight tests Japan’s H3 suffered a high-profile setback on Dec 22: The rocket failed to deliver the Michibiki 5 navigation satellite to its intended orbit after an upper-stage issue, forcing JAXA into investigation mode and putting schedule pressure on Japan’s independent navigation ambitions. A space startup swung for history on Dec 22, and missed: South Korea’s Innospace attempted its first orbital launch with Hanbit-Nano from Brazil, but the rocket failed shortly after liftoff, a painful reminder that reaching orbit is still the hardest product milestone in this industry. China tested a new path to reuse on Dec 23: The maiden flight of the Long March 12A reached orbit, but its downrange booster landing attempt failed, signaling real momentum on reusability even as the recovery learning curve stays steep. ## Space connectivity and commercial satellites Direct-to-smartphone connectivity got a major hardware moment on Dec 23: AST SpaceMobile’s BlueBird 6 launched on India’s LVM3, putting an enormous communications array into orbit as the company pushes toward cellular broadband that works with everyday phones. ISRO’s commercial launch playbook kept expanding: The BlueBird 6 mission also underscored how India’s heavy-lift capacity is being pulled into global commercial programs, not just national missions, with more Western satellite operators looking at India as a credible option on the manifest. ## Industrial chess moves in the US launch sector A rare executive shake-up hit on Dec 22: Tory Bruno stepped down as president and CEO of United Launch Alliance, a change that lands as Vulcan is still climbing its operational ramp and the US national security launch market remains intensely competitive. And then the next move arrived on Dec 26: Bruno joined Blue Origin, instantly adding seasoned launch-operations leadership to a company that has been investing heavily in manufacturing scale, test infrastructure, and a faster path to routine flight tempo. ## Earth observation and weather infrastructure SpaceX’s year-end schedule got squeezed on Dec 27: The company scrubbed another attempt to launch Italy’s COSMO-SkyMed Second Generation satellite due to ground-side issues, a small operational hiccup with outsized visibility because it was tracking as a year-closing mission. China added new capacity in geostationary weather on Dec 26: Fengyun 4C reached orbit, reinforcing how meteorology and climate monitoring remain one of the quiet workhorses of national space programs, with real economic value and constant demand for refresh.
