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。    Shares of Dollar General are up more than 7% before the opening bell Friday after the discount chain said Todd Vasos will be returning as CEO after a streak of disappointing quarterly profits.The company has missed Wall Street profit projections in four of the five past quarters and shares have fallen nearly 60% this year. The company has also wrestled with a number of labor issues. In July a National Labor Relations Board judge said that Dollar General violated federal labor law and “clearly intended to interfere” with worker rights in efforts to quell unionization at a Connecticut store.Violations from the Dolgen Corp., which operates Dollar General stores, included wrongfully firing an employee and making an implied threat to close the location in Barkhamsted, the NLRB decision read — adding that the company also sent corporate officials to the store and other locations across Connecticut in response to a 2021 union drive.Beyond unionization, Dollar General has faced multiple penalties for store safety over the years — including federal citations for electrical hazards and obstructed fire exits. As of May, the Labor Department’s Occupational Safety and Health Administration had proposed more than $21 million in penalties since 2017 after conducting 240 store inspections nationwide.Vasos stepped down as Dollar General’s top executive in 2022 after seven years. He takes over from Jeff Owen.Under Vasos' leadership, Dollar General expanded its store base by about 7,000 locations, added nearly 60,000 net new jobs, increased annual sales revenue by more than 80%, and more than doubled its market capitalization to approximately $58 billion. "At this time the board has determined that a change in leadership is necessary to restore stability and confidence in the company moving forward,” the company's chairman, Michael Calbert, said in a prepared statement.While saying the switch back to Vasos is not surprising, Citi analyst Paul Lejuez said many of the issues beguiling the company took root under his control. “While many of the issues surfaced shortly after Owen took over the CEO role, we believe many of these challenges had their origins while Vasos was CEO,” said in report published shortly after the leadership change was announced. “We do not believe there is a simple fix.” Dollar General, based in Goodlettsville, Tennessee, expects 2023 net sales growth in a range of 1.5% to 2.5%. Its prior outlook was for sales growth between 1.3% and 3.3%.。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。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。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。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。
