علم · Long March 7A failureThousands Cheered as a Rocket Turned to Fire at 85 Secondsمکتوب ۱۶ شهریور ۱۴۰۵ ساعت ۲۱:۲۲ (UTC)تماشامتن پیادهشده0:00An uncrrewed rocket turned into a ball0:01of fire in midair while thousands0:03cheered on a sweltering night on Hanan's0:05coast. A public beach spectacle turned0:07into a lowaltitude explosion in front of0:09families, torching a communication0:11satellite and grounding China's0:13workhorse fleet. The failure now0:15threatens the next moon mission. What0:16made a routine climb blow apart at peak0:19pressure? And can the tourism launch0:20models survive a fireball over the0:22crowd? This was at 10 of August 2026 at0:262002 Beijing time. Shortly after 8 on a0:28sweltering August night from Wang Space0:31[music] Launch Site on the coast of0:32Hainen launch complex 2011, the vehicle0:36was uncrrewed. Video shows a normal0:38ascent for [music] about 80 to 900:39seconds, commonly cited as about 850:41seconds before a catastrophic breakup0:44during the combined [music] burn of the0:45core first stage and its four strap-on0:47boosters near maximum aerodynamic0:48pressure. 85 [music] seconds is not0:51orbit. It is still thick atmosphere,0:53still full thrust, still over water.0:55[music] The rocket never had speed or0:57altitude to reach space, and the entire0:59stack was destroyed in that window.1:01Hours of anticipation [music] on the1:02beach ended in a sky- filling flash that1:04many did not immediately recognize as1:06failure. For decades, launches left1:08remote desert [music] pads with no1:09audience. When Chang changed that,1:12operational for major missions since1:132016, [music]1:14the coastal site has become the public1:16face of the program, a tourism economy1:18where viewing platforms and beaches pack1:20with thousands for each window. The1:22[music] cheering that continued even as1:24the fireball expanded shows how1:25completely spaceflight has become an1:27open [music]1:28crowd-based event amid an accelerating1:30race with the United States. The1:32confirmed payload was Jonging 4B, also1:34rendered China SAT [music] 4B, a1:36communication satellite widely assessed1:38as military communications [music] bound1:40for geostationary transfer orbit. It was1:42destroyed with the rocket. Debris fell1:44over the South China Sea and nothing1:46reached orbit. [music] China Daily1:47described technical malfunctions and a1:49China National Radio Bulletin that1:51briefly named the payload around liftoff1:52was later removed. International [music]1:54coverage described a catastrophic1:56mid-air explosion cataloged as China's1:58fourth orbital failure of 2026 and the2:01second failure for the long [music]2:02March 7th A type since its 2020 maiden2:05flight, the 18th mission of the type.2:07The trajectory [music] carried the stack2:09out over water and viewing distance did2:11the rest. Debris came down in the sea,2:13not on the beaches. No verified2:15injuries, deaths, or significant2:17property damage have been reported.2:18[music] Spectators watched from2:20designated beaches and viewing areas,2:22including the Wen Chang Viewing Center,2:24managed for launch tourism. [music]2:26Safety held this time, but the episode2:28exposes an open viewing strategy to a2:30lowaltitude failure in front of2:32thousands, including families where a2:34shift in [music] wind or debris2:36footprint would have mattered. The2:37contradiction is in language and timing.2:39[music] The restrained anomaly wording2:41arrived hours later, leaving the crowd's2:43reaction as the first [music] public2:45record. While phones streamed a2:46fireball, no detailed official timeline2:48or engine data has been released,2:50[music] and contractor China Aerospace2:51Science and Technology Corporation has2:53not issued a public statement. User2:56videos were deprioritized or removed on2:58Chinese social media, while neutral3:00industry commentary noted simply how3:02hard rocket engineering remains. The3:04Long March 7A uses six YF-100 [music]3:08cryogenic engines across its core and3:10four boosters, the same family that3:12powers Long [music] March 5 boosters and3:14other variants. That shared hardware is3:16why the fleet was [music] grounded and3:17inspected pending determination with3:19analysts suggesting a standown possibly3:22until late 2026. The JTA 3 test slated3:25for 11 August was stood [music] down and3:27the Chang 7 lunar mission planned for3:3024th of August on a long March 5 faces3:32delay risk into autumn windows if the3:34investigation implicates the common3:36engines. A subsequent successful [music]3:38long March 12th flight using related3:40engines suggested the issue may not be3:42fleetwide, but no official [music] root3:43cause has been published. The same3:45tourism push extends far beyond the pad.3:48In northern Inner Mongolia, Black3:49Volcanic Rock has [music] been developed3:51as a Mars simulator where visitors rent3:53spaceacuit costumes. China launched its3:55first rocket in 1960 and now targets a3:58crude moon landing by 2030, followed by4:00a crude Mars mission. The Reuters video4:02published 20 August is [music] a4:04retrospective of the same August4:05failure, not a separate launch, a date4:08consistently corroborated across state4:10and [music] international reporting. The4:11crowd scale remains thousands with no4:13higher verified figure. The answer4:15tonight is incomplete. The technical4:17determination [music] beyond anomaly and4:19technical malfunction has not been4:21released. Whether structural engine or4:23termination triggered, the fleet stays4:25grounded. The next manifests wait. And4:27the unresolved question is whether Wen4:29Chang's beachfront model adjusts viewing4:31distance or guidance before the next4:32crowded night launch puts thousands4:34under another climb.
