我国成功发射天链三号01星

北京时间7月29日19时50分，中国在文昌航天发射场使用长征七号改运载火箭成功将天链三号01星发射升空12。卫星顺利进入预定轨道，这是长征系列运载火箭的第659次飞行12。

天链三号01星由中国航天科技集团五院研制2，主要用于为飞船、空间实验室、空间站等载人航天器提供数据中继和测控服务，同时为中、低轨道资源卫星提供数据中继和测控服务12。长征七号改运载火箭可适配直径4.2米和3.7米两种整流罩，具备一箭一星和一箭双星发射能力2。长征七号改已进入高密度发射常态化阶段，此次任务是该型号今年的第3次飞行2。

China successfully launched the Tianlian-3 01 satellite on July 29, 2026, at 7:50 p.m. Beijing time from the Wenchang Space Launch Center, using a Long March 7A carrier rocket.12 The satellite entered its designated orbit as planned.12

Developed by the Fifth Academy of China Aerospace Science and Technology Corporation, the Tianlian-3 01 satellite is designed to provide data relay and tracking and control services for crewed spacecraft including space modules and space stations, as well as for medium and low-Earth-orbit resource satellites.2 This mission marked the 659th flight of the Long March rocket family.12 The Long March 7A rocket is capable of adapting to fairing diameters of 4.2 meters and 3.7 meters, enabling both single and dual satellite launch capabilities.2 With this launch, the Long March 7A entered a phase of high-frequency launch normalization in 2026, marking its third flight of the year.2
