海洋二号E卫星是国家民用空间基础设施中长期发展规划的业务卫星,是一颗海洋动力环境极轨卫星。它将接替海洋二号B星,保证观测数据的连续性,实现对全球海洋动力环境的稳定可靠探测。
卫星主要配置雷达高度计、微波散射计、微波辐射计、校正辐射计、船舶自动识别系统和数据收集系统等有效载荷,将对海面高度、有效波高、海面风场实现高精度、高分辨率的实时观测,为中国减灾、气象、交通、测绘等行业提供实测数据,助力国民经济建设、海洋科学研究、全球气候变化研究等领域高质量发展。
长征四号乙运载火箭是由中国航天科技集团八院抓总研制的常温液体三级运载火箭,具备发射多种类型、不同轨道要求卫星的能力,可执行一箭一星或多星发射任务,其700公里太阳同步轨道运载能力可达2.5吨。本次任务中,长征四号乙运载火箭首次在高温工况下采用并行加注模式。
此次任务是长征系列运载火箭的第654次飞行。(完)

French President Emmanuel Macron has urged Europe to develop an independent crewed space flight capability within ten years. The call, made at a Paris space summit, aligns with European Space Agency chief Josef Aschbacher's push for increased resources and autonomy.

China postponed its Chang'e-7 lunar mission after failing to meet launch requirements, rolling the rocket back to its assembly building. Analysts noted the delay could temporarily ease political and media pressure on NASA.

NASA's mission to rescue the Swift Observatory failed. The commissioned Katalyst unmanned spacecraft experienced a technical problem and spun out of control. NASA announced that it had canceled the rescue. It is expected that the Swift Observatory will naturally fall into the Earth's atmosphere and burn up later this year.

Independent trackers debate two unconfirmed explanations—a YF-100 engine anomaly or a structural failure near Max-Q—following a rocket break-up 85 seconds after launch.

China suffered a rare rocket failure as an unmanned Long March 7A exploded less than 90 seconds after lifting off from the Wenchang Space Launch Site, destroying the ChinaSat-4B communications satellite.

Chinese space scientists have outlined a lunar exploration concept featuring three astronauts working alongside intelligent machines, including robot dogs and a pressurized rover.
