Chinese commercial space firm completes long-duration test of reusable rocket engine_我的网站

A |     现年71岁的著名导演王晶，近年积极转战网络，开设YouTube频道《王晶笑看江湖》大爆娱乐圈秘闻，吸引大量网友追看。在上月播出的一集节目中，王晶回顾完香港喜剧发展史后，突然一脸认真地宣布停播消息：“我在将近几个月内，工作会非常繁忙，而且身体也不太好，所以节目会暂停一段日子。”当时不少网友发现他在节目中全程不断用力眨眼，显得非常吃力，纷纷担心是否为中风前兆。

China's commercial reusable launch vehicle sector continues to make steady progress, as a company announced on Friday that it had completed a long-duration test firing of an engine for a large recoverable carrier rocket.
Deep Blue Aerospace, a commercial space startup based in Wuxi, east China's Jiangsu Province, said it recently completed a 100-second static-fire test of its Thunder-RS engine, a 130-tonne-class liquid-oxygen kerosene engine designed for the company's large reusable rocket, Nebula-2.
The test reached 1,297.5 kilonewtons of thrust, or about 132.3 tonnes. The company said multiple short-duration test firings had been conducted previously to evaluate engine performance, with no anomalies recorded.
The recent 100‑second run was the engine's first crossing of that steady‑state duration threshold, serving as a comprehensive verification of its performance, the company said.

Rocket reusability can greatly cut launch costs and boosts launch frequency, making it key to achieving large-scale, routine access to space.
China launched the reusable rocket Zhuque-3 on Wednesday morning, achieving its first recovery of a rocket's first stage on land, marking the country's first successful land-based recovery. This mission followed the successful sea-based net recovery of the Long March-10B's first stage on July 10.
More models of Chinese reusable rockets are scheduled to conduct tests this year. 
。不过，王晶最新近照日前曝光——虽然身形明显消瘦，但精神状态看起来依然不错。尽管宣布暂停幕前工作休养身体，王晶的近况终于有了消息。曾为TVB艺人、近年转型为网红的女儿王海榛（前艺名王子涵），8月23日在Instagram上分享了一家四口为妈妈丁德君庆祝生日的合照。照片中，站立合影的王晶身材比以往明显消瘦不少，连标志性的大肚腩也小了一圈。对比2023年一家人庆祝母亲节时的旧照，当时王晶面部圆润，与近照相比确实清瘦了许多。不过，照片中的他笑容满面，精神状态看起来相当不错。其实针对眨眼问题，王晶去年曾亲自拍视频解释，称自己长期受严重的干眼症困扰。他坦言找过多位眼科医生都无法根治，形容这是“不治之症”：“从小到大都这样，后来好了一阵子，但一累又复发了，所以我索性放弃了，习惯了。”只要身体疲惫，眼干情况就会发作，他希望大家不要过于担心。
