A |     After serving more than a month of in-school suspension over his dreadlocks, a Black student in Texas was told he will be removed from his high school and sent to a disciplinary alternative education program on Thursday.Darryl George, 18, is a junior at Barbers Hill High School in Mont Belvieu and has been suspended since Aug. 31. He will be sent to EPIC, an alternative school program, from Oct. 12 through Nov. 29 for “failure to comply” with multiple campus and classroom regulations, the principal said in a Wednesday letter provided to The Associated Press by the family.Principal Lance Murphy wrote that George has repeatedly violated the district's “previously communicated standards of student conduct." The letter also says that George will be allowed to return to regular classroom instruction on Nov. 30 but will not be allowed to return to his high school's campus until then unless he's there to discuss his conduct with school administrators.Barbers Hill Independent School District prohibits male students from having hair extending below the eyebrows, ear lobes or top of a T-shirt collar, according to the student handbook. Additionally, hair on all students must be clean, well-groomed, geometrical and not an unnatural color or variation. The school does not require uniforms.George's mother, Darresha George, and the family's attorney deny the teenager's hairstyle violates the dress code. The family last month filed a formal complaint with the Texas Education Agency and a federal civil rights lawsuit against the state’s governor and attorney general, alleging they failed to enforce a new law outlawing discrimination based on hairstyles. The family alleges George's suspension and subsequent discipline violate the state’s CROWN Act, which took effect Sept. 1. The law, an acronym for “Create a Respectful and Open World for Natural Hair,” is intended to prohibit race-based hair discrimination and bars employers and schools from penalizing people because of hair texture or protective hairstyles including Afros, braids, dreadlocks, twists or Bantu knots. A federal version passed in the U.S. House last year, but was not successful in the Senate.The school district also filed a lawsuit in state district court asking a judge to clarify whether its dress code restrictions limiting student hair length for boys violates the CROWN Act. The lawsuit was filed in Chambers County, east of Houston.George’s school previously clashed with two other Black male students over the dress code. Barbers Hill officials told cousins De’Andre Arnold and Kaden Bradford they had to cut their dreadlocks in 2020. Their families sued the district in May 2020, and a federal judge later ruled the district’s hair policy was discriminatory. Their pending case helped spur Texas lawmakers to approve the state’s CROWN Act. Both students withdrew from the school, with Bradford returning after the judge’s ruling. ___AP journalist Juan Lozano contributed to this report from Houston.___The Associated Press education team receives support from the Carnegie Corporation of New York.

B | 作为这条产线上生产的第一颗卫星，"雄安一号"也成为面向卫星组网时代的"工程样板间"。鸿擎科技"鸿鹄03星"项目经理 郑书强：单就是这条卫星产线，我们现在产能就瞄着每年100颗的这个目标去做的，可能未来我们就会比如瞄着年产300颗、500颗这个目标去发展。北京航空航天大学宇航学院副教授 杨良："雄安一号"（鸿鹄03星）是为全国商业航天发展，尤其是低轨卫星商业应用打了个样。过去大家印象里卫星研制都是高精尖、小批量、定制化的模式。而"雄安一号"(鸿鹄03星)是真正在雄安本地研发、本地智能制造出来的卫星，验证了低成本、标准化、批量化造星的全新模式。这不仅让入驻雄安的航天企业彻底跑通了生产、研制、在轨验证的完整链条，补齐了新区空天信息产业的关键一环，更给全国商业航天产业提供了可复制、可推广的"雄安模式"。当前，全球已经进入低轨卫星组网的太空竞赛阶段。低轨轨道与频谱属于稀缺战略资源，遵循国际规则"先到先得"，建设大规模卫星互联网星座，已经成为各国抢占太空数字基础设施的重要方向。加速推进我国低轨卫星组网建设，不仅事关天地一体化信息网络构建，更关系国家通信安全、6G空天地一体化发展与新质生产力培育。北京航空航天大学宇航学院副教授 杨良：一方面，国际上轨道频谱资源竞争非常激烈，留给我们的时间窗口很紧；另一方面，传统卫星单件小批量研制模式，根本满足不了巨型星座成千上万颗卫星的部署需求。"雄安一号"(鸿鹄03星)最大的价值，就是把"流水线造卫星"这套模式送上太空进行验证，解决造得慢、成本高的卡点，为我们国家快速部署低轨星座趟出了工程化道路。
