A |     冀时新闻报道 8月19日早上，在甘肃酒泉东风商业航天创新试验区，首颗"雄安造"卫星，编号为鸿鹄03星的"雄安一号"，搭乘朱雀三号重复使用遥二运载火箭成功发射入轨。8月19日7时35分，伴随着震彻戈壁的轰鸣声，烈焰喷涌而出，朱雀三号重复使用遥二运载火箭拔地而起、直冲苍穹，搭载着"雄安一号"奔赴浩瀚太空。

B | 鸿擎科技副总裁 闫旭：我太激动了！这颗卫星是我们依托全国首条流水线式自动化卫星批量产线，自主研制的，搭载了多项具有行业突破意义的关键技术。今天终于圆梦太空，我们无数个日夜坚守、上千次的反复试验、无数次的复盘迭代，所有的付出都是值得的！本台记者 李耀阳：这里是位于雄安新区的鸿擎科技卫星智能运管中心，就在刚刚朱雀三号(重复使用)遥二运载火箭成功发射，将"雄安一号"卫星(鸿鹄03星)送入到了预定轨道，卫星的遥测数据一切正常，太阳翼已经顺利地展开。    KYIV -- Ukrainian forces are trying to hold off a major new Russian offensive operation in the strategic city of Avdiivka.Russia sent dozens of tanks and armored vehicles and thousands of troops into the assault, which started four days ago."They are hitting with everything they have. Yesterday a lot of armor was used, they came in columns. The assault isn’t stopping neither day or night," Vitaliy Barabash, the head of Avdiivka’s military administration, said on Ukrainian television.Russia has also launched smaller offensive operations at points all along the front line, intensifying an offensive near the city of Kupiansk, which Ukraine liberated last year, according to Ukrainian troops on the ground.But the main attack is on Avdiivka, which holds major strategic significance for both sides. Avdiivka is located close to Donetsk, the capital of the Russian-occupied Donetsk region.Ukraine heavily fortified the line at Avdiivka prior to Russia’s full-scale invasion last year, constructing deep trenches and a system of underground bunkers. As a result, Russian forces have barely advanced near the city.Russia now appears to be seeking to cut off Avdiivka and surround the Ukrainian forces inside its defenses."For the entire time of the war, there has never been such an offensive around Avdiivka, even though they’ve attacked Avdiivka since 2014," Oleksiy Dmitrashkivsky, chief spokesman for the Command of Ukraine's Territorial Defense Forces, told ABC News.He said two Russian battalions, numbering around 2,000 men and backed by dozens of tanks and other armored vehicles, had begun the attacks, pushing from the northwest and southwest. A massive artillery and air barrage had preceded the assault and has continued since, with frequent strikes on the city itself.So far the Russian assault has appeared to have gone badly, according to Ukrainian military officials and open source researchers tracking the losses.Barabash, Avdiivka’s military administration chief, said at least 40 Russian armored vehicles had been lost in two days. Videos circulating online of the attacks appeared to largely support those claims, with some open source researchers saying 30 to 50 Russian tanks and other vehicles had been damaged or destroyed.Ukraine’s general staff claimed over 1,000 Russian troops had been killed and injured since the new offensive operation began.The Institute for the Study of War said Russia had managed to capture roughly 4.52 square kilometers of territory from different directions around Avdiivka in the last three days."Russian forces have not secured any major breakthroughs near Avdiivka as of Oct. 12 and are unlikely to immediately cut off Ukrainian forces in the city," ISW wrote in its daily briefing Thursday.Ukrainian military officials said their troops have successfully held the lines, inflicting heavy casualties on the Russian attackers, though Ukrainian casualties were also large.The new Russian offensive -- the scale of which seemed to catch some analysts off-guard -- nonetheless was significant because it appears to show Russia's attempt to regain the initiative in the war."The Russians have decided that they can already start their own counterattack in [the Avdiivka] direction," Dmitrashkivsky said. "They are taking advantage of the fact that the attention of the whole world is on the events in Israel and they have started an active phase along the entire front line."He said the Russian attack near Avdiivka had involved a mixed force of paratroopers and poorly trained forces, as well as so-called Storm Z units -- detachments of convicts sent to fight."They were very weakly prepared and that showed in their losses," Dmitrashkivsky said.The attack had been exceptionally large, he added, requiring huge efforts from Ukrainian troops to blunt it.Most analysts believe Russia likely still lacks the manpower to make significant gains in an offensive, including around Avdiivka. But the push indicated Russia hopes to further blunt Ukraine’s counteroffensive with its own counterpunch, coming as the weather starts to worsen.Ukraine is continuing to press its own attacks in the southern Zaporizhzhia region where its counteroffensive is focused and around the city of Bakhmut.。接下来，"雄安一号"还将在真实的宇宙空间环境下，对星上搭载的各项新技术、新部件开展多轮在轨测试，各项性能指标都将接受太空环境的实战检验。鸿擎科技卫星智能运管中心负责人 张子龙："雄安一号"(鸿鹄03星)在轨实测数据，将持续反哺模型训练、驱动算法调优。鸿擎科技将持续打磨巨型星座天地一体化智能运管核心能力，为后续万星星座常态化运管，奠定坚实技术基础。

C | 在"雄安一号"卫星成功入轨的同时，朱雀三号重复使用遥二运载火箭一子级，按预定程序成功着陆于甘肃省民勤县朱雀三号着陆场坪，成为我国首款成功入轨并实现陆地回收的运载火箭。北京航空航天大学宇航学院副教授 杨良：这个火箭的陆上回收，可以把它理解为一次极高难度的空中倒车入库，任何一个环节出现小的偏差都可能影响成败。

D | 此次成功是我国商业火箭在陆上垂直软着陆技术上的重大突破，为降低发射成本、提高发射频率创造条件。
