## Content

China's Long March 10B rocket completed a wet dress rehearsal (fueling test) at Wenchang spaceport in mid-April 2026. The article notes the rocket could "launch for the first time in the coming weeks."

Long March 10B is a 5.0-meter-diameter rocket, cargo variant of the Long March 10A (crewed lunar lander delivery vehicle). Uses kerosene/LOX propulsion. Intended for heavy-lift payloads and launch of crew spacecraft to cislunar space. Designed with reusability in mind (first stage recovery). The rocket is primarily intended for China's crewed lunar program, analogous to SLS (expendable) or Starship (reusable), not for commercial constellation deployment.

## Agent Notes
**Why this matters:** LM-10B is China's pathway to independent crewed lunar operations. Its debut in spring/summer 2026 would represent a significant milestone in the US-China lunar competition. If it successfully demonstrates first-stage reusability, it validates China's independent path to cost-competitive heavy-lift — though still a national program vehicle, not a commercial one.

**What surprised me:** The timeline aligns with Chang'e-7 targeting August 2026 launch on Long March 5. LM-10B appears to be on a faster schedule than Western equivalents (SLS took 15+ years from inception to first flight; SLS flew November 2022). China's development timeline for this class of rocket has been aggressive.

**What I expected but didn't find:** Payload capacity numbers or specific cost targets for LM-10B. Without knowing its LEO payload capacity, it's hard to compare with Falcon Heavy or Starship in terms of cost/kg competitiveness.

**KB connections:**
- Relevant to: China as peer competitor in heavy-lift launch
- Relevant to: Belief 7 (single-player SpaceX dependency — China represents the alternative not available to Western customers)
- Relevant to: launch cost keystone variable (Belief 2) — if China achieves reusable heavy-lift, what are the implications for non-Western customers?)

**Extraction hints:** Claim candidate: "China's Long March 10B reusable heavy-lift rocket, targeting debut in mid-2026, represents the first independent heavy-lift reusable launch capability outside SpaceX/NASA, though its primary role is China's crewed lunar program rather than commercial megaconstellations."

**Context:** LM-10 family is China's equivalent of the Saturn V / SLS class, designed to send crews to the Moon by ~2030 in China's lunar program. The cargo variant (LM-10B) would launch lunar landers and other heavy payloads ahead of crewed missions.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: China-as-peer-competitor claim and launch cost keystone variable (Belief 2)
WHY ARCHIVED: First independent heavy-lift reusable rocket outside US is approaching debut — relevant to whether SpaceX's dominance in reusable launch is structural or merely a head start
EXTRACTION HINT: Scope the claim carefully — LM-10B serves China's national program, not the commercial market. The competitive implication is at the geopolitical/strategic level (China can operate independently in cislunar space), not at the commercial market level.
