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. 
。这是张帅第一次闯入温网女双1/4决赛，实现在四大满贯都打进过女双八强的成就。张帅和去年温网女双冠军梅尔腾斯配合愈加默契，两人一上来就破掉15号种子N-基切诺克/奥拉鲁的首个发球局，用2-0的比分开盘。之后张帅/莫藤斯虽浪费掉拉持续拉开分差的机会，但还是凭借第10局胜盘局里直落4分的保发抢下首盘。比赛进入到第2盘，张帅/莫藤斯又一次开盘破发得手。

B | 这一回中国金花和搭档一路领先至盘末，顺利破掉对手非保不可的第9局。

生涯至此，张帅在四大满贯的女双赛场上都最起码打进过八强，其中澳网和美网的最好成绩都是冠军。她的搭档梅尔腾斯已连续9场温网女双不败，在澳网、温网和美网都拿到过最后的冠军，法网也打进过半决赛。由于金花组合徐一璠/杨钊煊挥霍次盘领先的发球胜盘局，以3-6，5-7的比分不敌7号种子瓜拉奇/克莱帕奇，张帅错过1/4决赛和同胞上演中国德比的机会。瓜拉奇/克莱帕奇将与张帅/莫藤斯争夺半决赛入场券。
