China's Long March-12B Rocket Debuts, Competes with SpaceX's Starlink in Internet Megaconstellation Race
  • A Long March-12B launch from the Dongfeng Commercial Aerospace Innovation Test Zone near Jiuquan marked a debut flight that deployed two Qianfan satellites for China’s internet megaconstellation, positioned as a rival to SpaceX’s Starlink.

  • CASC said a booster landing would be attempted on a future flight, continuing China’s exploration of reusable launch tech alongside earlier efforts with the Long March 12A and private ventures.

  • Analysts note China’s irregular adherence to international debris disposal norms and safety practices, contrasting with oversight from ICAO and IMO frameworks.

  • The launcher resembles SpaceX’s Falcon 9 in design and propulsion—about 70 meters tall with a reusable first stage powered by nine kerosene/LOX engines—though this flight did not land the booster.

  • The article situates the launch within broader space race dynamics, hinting at potential crewed Moon ambitions by 2030 and situating it against NASA’s Artemis timeline.

  • Analysts warn that rapid mega-constellation expansion could strain low-Earth orbit, prompting discussions on orbital traffic management akin to air-traffic control for satellites.

  • The Long March-12B debuted for the first time with no advance safety warnings, launching from Jiuquan carrying Qianfan satellites.

  • The Long March-12B, a partially reusable rocket, is described as similar in capability to Falcon 9 and follows the February test flight of the moon-rocket prototype Long March 10.

  • The launch took place from the Gobi Desert site with no prior airspace or maritime notices, challenging typical safety procedures aligned with international norms.

  • The Long March-12B is portrayed as comparable to Falcon 9 capability-wise and marks a cross-year progression after the moon-rocket prototype’s orbit and controlled splashdown.

  • Experts suggest competition between Qianfan and Starlink could accelerate global internet coverage, benefiting remote areas.

  • The Long March-12B is a modified two-stage, commercially optimized rocket launching from the Dongfeng site near Jiuquan, with its debut in mid-2024.
