Critical systems such as the propellant tank farm, water tower, and Horizontal Integration Facility largely survived, allowing recovery work to begin quickly.<\/p>\n<p>The incident halted Blue Origin\u2019s operational cadence for New Glenn, which had completed three prior flights. The third mission in April 2026 successfully recovered its first stage but experienced a second-stage anomaly that prevented the payload from reaching its intended orbit.<\/p>\n<p>The May 28 explosion, occurring just as the company prepared to resume flights, represented one of the most significant pad accidents in recent commercial spaceflight history and forced a major rethink of operations at the company\u2019s sole New Glenn launch site.<\/p>\n<p>In an August 5 update, Limp confirmed that investigators have traced the origin of the anomaly to the main oxygen valve on one of the seven BE-4 engines powering the booster.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">Wanted to give an update on the hotfire anomaly investigation.

These changes can be retrofitted into existing engines rather than necessitating entirely new hardware production runs, a development that should help preserve manufacturing timelines and control costs. Updated valve hardware is already in production and expected to be ready by the end of August.<\/p>\n<p>In parallel, teams continue working through the remaining branches of the formal fault-tree analysis. Limp described the overall path forward as clear, with Blue Origin still targeting a return to flight before the end of 2026 once the launch pad itself is ready.<\/p>\n<p>The BE-4 engine is also used on United Launch Alliance\u2019s Vulcan Centaur, raising the possibility that any shared design considerations could affect that vehicle as well, though ULA has been collaborating on the review. Ahead of the ill-fated New Glenn\u2019s launch, it was claimed it was using a new family of BE-4, thus potentially separating commonality and freeing Vulcan to proceed.<\/p>\n<p>Procedural issues may also have been in play, especially in light of rumored launch personnel changes at Blue Origin.<\/p>\n<p>While the investigation advances, physical recovery and redesign work at Launch Complex 36 continues at a rapid pace. <strong><em>An extensive collection of ground and flyover photos of LC-36\u2019s return is available to L2 members here<\/em><\/strong>.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">Team is moving at record speed out at the pad.

This approach eliminates the need to rebuild the destroyed transporter-erector and is expected to support higher launch cadence once operations resume.<\/p>\n<p>The surviving vehicle access tower (also called the support or umbilical tower) has been destacked in sections for parallel modifications, including addition of new access platforms and fluid\/control systems, before restacking.<\/p>\n<p>At the same time, Blue Origin is progressing work on its next launch complex just a few hundred meters to the north: Launch Complex 36B.<\/p>\n<p>This pad is intended to support the much larger and more capable New Glenn 9\u00d74 variant. Standing nearly 120 meters (about 400 feet) tall, compared with the current 7\u00d72 configuration\u2019s roughly 98 meters, the 9\u00d74 will feature nine BE-4 engines on the first stage and four BE-3U engines on the second stage.<br \/>\n<img decoding=\"async\" width=\"100%\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2026\/08\/NSF-2026-08-08-22-03-13-258.jpg\">It is designed to deliver approximately 70 metric tons to low Earth orbit, along with substantially greater capacity to higher-energy trajectories, and will incorporate a larger 8.7-meter-diameter fairing.<\/p>\n<p>Constructing a new pad involves far more than steel and concrete; it also requires extensive regulatory paperwork. One key element is the Federal Aviation Administration\u2019s obstruction evaluation process, which analyzes whether proposed tall structures, permanent or temporary, could pose hazards to existing aerial navigation routes or nearby airports.<\/p>\n<p>This week, Blue Origin filed for a new analysis covering a large mobile crane up to 228 meters tall that will support construction activities at the LC-36B site. The company submitted a separate application for a mobile crane to be used at the neighboring LC-36A for ongoing New Glenn operations, indicating that installation of the heavy-lift equipment is approaching.<\/p>\n<p>Notably, Blue Origin also updated two existing obstruction analyses originally filed in April for structures at LC-36B. Those earlier filings described an Umbilical Launch Tower planned at up to 152 meters and a Lightning Protection Tower at up to 182 meters.<\/p>\n<p>The revised documentation significantly alters those heights: the umbilical tower is now listed at 83.8 meters, while the lightning protection tower grows to 218 meters.<\/p>\n<p>The change is puzzling given the scale of New Glenn 9\u00d74. At nearly 120 meters tall, the rocket would stand almost 40 meters above the top of an 83.8-meter umbilical tower. An umbilical tower must provide connections to the second stage and potentially to the payload fairing for environmental control and other services.<br \/>\n<img decoding=\"async\" width=\"100%\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2026\/08\/NSF-2026-08-08-22-05-38-650.jpg\"><br \/>\nEven under optimistic assumptions, placing the highest connection at the very top of the shortened tower and attaching it to the base of the fairing, the geometry implies an unusually tall fairing or a fundamental shift in how services are delivered.<\/p>\n<p>The discrepancy suggests that either the rocket\u2019s design itself is evolving or that the ground systems architecture for 9\u00d74 is being rethought in ways not yet publicly detailed.<\/p>\n<p>Taken together, the investigation progress, pad reconstruction under a revised concept of operations, and ongoing development of LC-36B paint a picture of a company moving deliberately but aggressively to recover from a major setback.<\/p>\n<p>Lead Image: Blue Origin.<\/p>\n<p><img decoding=\"async\" width=\"100%\" src=\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2025\/02\/L2_Membership_ShopBanner_c3acb3ad-719d-484c-8c2d-3ca9d11244f0-1.webp\"><\/p>\n<p>The post Blue Origin working engine resolutions and dual pad future appeared first on NASASpaceFlight.com.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Blue Origin is nearing the end of its investigation into the catastrophic explosion of a New Glenn rocket that occurred roughly two and a half months ago, with CEO Dave Limp providing an update that pins the anomaly to a specific component in one of the booster\u2019s engines, although root cause analysis is continuing.
