The redesigned New Shepard spaceship will re-fly the payloads that were part of the uncrewed mission that went awry.<\/p>\n<p>No people were aboard New Shepard during last year\u2019s launch from Blue Origin\u2019s Launch Site One in West Texas. No one was injured on the ground, and there was no damage to ground-based systems. All of the debris from the mishap was recovered within the designated hazard area.<\/p>\n<p>Flights have been suspended during Blue Origin\u2019s investigation, which was conducted by a team including representatives from NASA and the National Transportation Safety Board with oversight by the Federal Aviation Administration. In an emailed statement, the FAA said the investigation \u201cremains open.\u201d<\/p>\n<p>\u201cThe agency is currently reviewing the company\u2019s submission of its mishap report,\u201d it said. \u201cFAA approval is required to close the investigation and for the New Shepard System to return to flight.\u201d<\/p>\n<p>Before the failure of the uncrewed research mission, known as NS-23, Blue Origin had flown 31 customers and special guests (including Bezos and his brother Mark, and Star Trek actor William Shatner) on six crewed suborbital trips. There were also more than a dozen uncrewed flights, many of which carried research payloads.<\/p>\n<p>Blue Origin\u2019s only other New Shepard failure occurred during the first test flight of the suborbital launch system in 2015. As was the case for that earlier failure, last September\u2019s mishap led to the loss of the rocket booster, but the capsule that would have held crew was recovered safely. Blue Origin said if there had been crew members aboard, they would have had a safe but rocky ride.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<iframe loading=\"lazy\" title=\"New Shepard launch anomaly (NS-23)\" width=\"800\" height=\"450\" src=\"https:\/\/www.youtube.com\/embed\/F6oTSgv4d_Y?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\"><\/iframe><br \/>\n<\/figure>\n<p>According to today\u2019s update, the direct cause of NS-23\u2019s anomaly was a thermo-structural failure of the BE-3PM engine nozzle. \u201cThe resulting thrust misalignment properly triggered the Crew Capsule escape system, which functioned as designed throughout the flight,\u201d Blue Origin said.<\/p>\n<p>To track down the cause, investigators examined the booster debris and reviewed video and telemetry from the mission. Close examination of fragments of the nozzle revealed hot streaks and other signs of thermal damage due to hotter-than-expected operating temperatures.<\/p>\n<p>Investigators \u201cdetermined that design changes made to the engine\u2019s boundary layer cooling system accounted for an increase in nozzle heating and explained the hot streaks present,\u201d Blue Origin said.<\/p>\n<figure class=\"wp-block-image size-full-width\"><img loading=\"lazy\" decoding=\"async\" width=\"630\" height=\"266\" src=\"https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2023\/03\/image002-630x266.png\" alt=\"\" class=\"wp-image-761311\" srcset=\"https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2023\/03\/image002-630x266.png 630w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2023\/03\/image002-1260x533.png 1260w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2023\/03\/image002-768x325.png 768w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2023\/03\/image002-1536x649.png 1536w, https:\/\/cdn.geekwire.com\/wp-content\/uploads\/2023\/03\/image002-2048x866.png 2048w\" sizes=\"(max-width: 630px) 100vw, 630px\"><figcaption data-nosnippet=\"\" class=\"wp-element-caption\">An aerial photo at left shows the terrain at Blue Origin\u2019s Launch Site One in West Texas.

But Blue Origin\u2019s vice president of commercial and international sales, Ariane Cornell, said at last week\u2019s Satellite 2023 conference that the company was \u201clooking to get back into flight with New Shepard by the end of this year.\u201d<\/p>\n<p>Blue Origin said the payloads that were in the capsule for last September\u2019s failed flight \u2014 half of which were funded by NASA \u2014 survived the mishap intact and would be re-flown.

Looking further ahead, Jeff Bezos\u2019 girlfriend, Lauren Sanchez, has said she hopes to take a suborbital spaceflight with an all-female crew by early 2024.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The booster for Blue Origin\u2019s New Shepard spaceship flares during last year\u2019s ascent.
