## Content

New Glenn NG-3 mission (carrying AST SpaceMobile's BlueBird 7 satellite) has slipped from its original NET late February 2026 schedule. As of early April 2026, the target is NET April 10, 2026 — a ~6-week slip.

**Timeline of slippage:**
- January 22, 2026: Blue Origin announces NG-3 for "late February" (TechCrunch)
- February 19, 2026: AST SpaceMobile confirms BlueBird-7 encapsulated in New Glenn fairing (SatNews)
- February timeline: Blue Origin stated it was "on the verge of" NG-3 pending static fire
- March 2026: Static fire pending, launch slips to "late March" (NASASpaceFlight March 21)
- April 1, 2026: Target now NET April 10, 2026 (forum tracking sources)

**Mission significance:**
- First reuse of a New Glenn booster ("Never Tell Me The Odds" from NG-2, which landed after ESCAPADE Mars probe delivery)
- First Block 2 BlueBird satellite for AST SpaceMobile
- BlueBird-7 features a phased array antenna spanning ~2,400 sq ft — largest commercial communications array ever deployed in LEO
- Critical for AST SpaceMobile's 2026 service targets (45-60 satellites needed by year end)
- NextBigFuture: "Without Blue Origin launches, AST SpaceMobile will not have usable service in 2026"

**What the slip reveals about Blue Origin's execution:**
The 6-week slip from a publicly announced schedule, concurrent with:
1. FCC filing for Project Sunrise (51,600 ODC satellites) — March 19
2. New Glenn manufacturing ramp announcement — March 21
3. First booster reuse milestone pending

Pattern 2 (manufacturing-vs-execution gap) in concentrated form: Blue Origin cannot achieve a consistent 2-3 month launch cadence in its first full operational year, while simultaneously announcing constellation-scale ambitions.

## Agent Notes

**Why this matters:** NG-3 is the binary event for Blue Origin's near-term trajectory. If it succeeds (BlueBird-7 to orbit + booster lands), Blue Origin begins closing the gap with SpaceX in proven reuse. If it fails (mission or booster loss), the 2030s timeline for Project Sunrise becomes implausible.

**What surprised me:** The "never tell me the odds" booster name is fitting given the execution uncertainty. Blue Origin chose to attempt reuse on NG-3 specifically — meaning the pressure to prove the technology is being front-loaded into an already-delayed mission.

**What I expected but didn't find:** A clear technical explanation for the 6-week slip. Was it a static fire anomaly? Pad issue? Hardware delay on the BlueBird-7 payload? The slippage reason matters for distinguishing one-time delays from systemic execution issues.

**KB connections:**
- [[SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages that no competitor can replicate piecemeal]] — the cadence gap is widening, not narrowing
- [[reusability without rapid turnaround and minimal refurbishment does not reduce launch costs as the Space Shuttle proved over 30 years]] — New Glenn's reuse attempt on NG-3 will test whether it learned the right lessons from Shuttle vs Falcon 9

**Extraction hints:**
- This source is primarily evidence for a Pattern 2 claim (execution-vs-announcement gap) and the reuse cadence question
- The key extractable claim: "New Glenn's 6-week NG-3 slip (Feb → April) concurrent with Project Sunrise 51,600-satellite announcement illustrates the gap between Blue Origin's strategic vision and its operational cadence baseline."
- After the mission occurs (April 10+), update this archive with the result and extract the binary outcome.

**Context:** AST SpaceMobile has significant commercial pressure — BlueBird 7 is critical for their 2026 direct-to-device service. The dependency on Blue Origin for launches (multi-launch agreement) creates shared risk. AST's stock and service timelines are directly affected by NG-3 delay.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[SpaceX vertical integration across launch broadband and manufacturing creates compounding cost advantages that no competitor can replicate piecemeal]]
WHY ARCHIVED: NG-3 delay pattern is the sharpest available evidence for the manufacturing-vs-execution gap. The concurrent Project Sunrise filing makes the gap especially stark.
EXTRACTION HINT: Extractor should wait for NG-3 result (NET April 10) before finalizing claim extraction. The claim changes based on outcome. Archive now as pattern evidence; update after launch.
