CEO Peter Beck says voids, or air pockets, formed between layers of carbon fiber during the curing process, which is especially difficult for large structures too big to fit into a standard autoclave. The delay follows an August update that had still held out hope for a late-year delivery to the Wallops Island launch pad. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why has Rocket Lab delayed the first launch of the Neutron rocket to 2027? Rocket Lab delayed Neutron's first launch to 2027 after discovering a manufacturing defect in the propellant tank domes of the rocket's reusable carbon composite first stage. Engineers found voids, or air pockets, between layers of carbon fiber in the domes, caused by difficulties curing large composite structures that don't fit into a standard autoclave. CEO Peter Beck confirmed the issue halted production for further investigation. _Engineers tracking hardware setbacks across the space industry follow updates like this on daily.dev._ ## Similar posts on daily.dev - [NASA says it needs to haul the Artemis II rocket back to the hangar for repairs](https://daily.dev/posts/nasa-says-it-needs-to-haul-the-artemis-ii-rocket-back-to-the-hangar-for-repairs-4qyiahvkm) · Ars Technica · 0 upvotes · 0 comments - [Blue Origin still does not know why New Glenn exploded but plans to fly again this year](https://daily.dev/posts/blue-origin-still-does-not-know-why-new-glenn-exploded-but-plans-to-fly-again-this-year-xtwzggmkb) · The Next Web · 0 upvotes · 0 comments - [Blue Origin still doesn’t know why its New Glenn rocket blew up last month](https://daily.dev/posts/blue-origin-still-doesn-t-know-why-its-new-glenn-rocket-blew-up-last-month-y5n2fe0n1) · TechCrunch · 0 upvotes · 0 comments - [Private Startups Are Rapidly Advancing Canadian Rockets](https://daily.dev/posts/private-startups-are-rapidly-advancing-canadian-rockets-hqqtefkbu) · IEEE Spectrum · 0 upvotes · 0 comments - [Rocket Report: Russia pledges quick fix for Soyuz launch pad; Ariane 6 aims high](https://daily.dev/posts/rocket-report-russia-pledges-quick-fix-for-soyuz-launch-pad-ariane-6-aims-high-m13vzfgqv) · Ars Technica · 0 upvotes · 0 comments --- [View this post on daily.dev](https://daily.dev/posts/neutron-s-first-launch-slips-again-amid-trouble-with-carbon-composites-qdkpzux5g) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Neutron’s first launch slips again amid trouble with carbon composites","url":"https://daily.dev/posts/neutron-s-first-launch-slips-again-amid-trouble-with-carbon-composites-qdkpzux5g","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/neutron-s-first-launch-slips-again-amid-trouble-with-carbon-composites-qdkpzux5g"},"datePublished":"2026-10-15T18:17:26.623Z","dateModified":"2026-10-15T18:33:29.684Z","description":"Rocket Lab's Neutron medium-lift rocket has slipped its first launch again, this time into 2027, after engineers discovered manufacturing defects in the carbon...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9722196ef65ed4db2886c9f2b49bda0d?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9722196ef65ed4db2886c9f2b49bda0d?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Ars Technica","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Ars Technica","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/80883e0e48a34b5ebcf93777016cb3fe","url":"https://daily.dev/sources/arstechnica"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/neutron-s-first-launch-slips-again-amid-trouble-with-carbon-composites-qdkpzux5g","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Ars Technica","item":"https://daily.dev/sources/arstechnica"},{"@type":"ListItem","position":3,"name":"Neutron’s first launch slips again amid trouble with carbon composites"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/neutron-s-first-launch-slips-again-amid-trouble-with-carbon-composites-qdkpzux5g#faq","mainEntity":[{"@type":"Question","name":"Why has Rocket Lab delayed the first launch of the Neutron rocket to 2027?","acceptedAnswer":{"@type":"Answer","text":"Rocket Lab delayed Neutron's first launch to 2027 after discovering a manufacturing defect in the propellant tank domes of the rocket's reusable carbon composite first stage.
