A |     Three children were killed in a house fire in New Orleans early Wednesday morning that was allegedly set by their father following an apparent domestic dispute, police said.The father -- identified by police as Joseph Washington Sr., 29 -- was apprehended following a manhunt Wednesday and faces multiple charges including second-degree murder, according to New Orleans Deputy Superintendent Ryan Lubrano."We are here because of the tragic and senseless, horrific deaths of three young children last night in a domestic violence situation," New Orleans interim Police Chief Anne Kirkpatrick said at a press briefing Wednesday.The children's mother called 911 at 11:55 p.m. Tuesday night to report that their father intended to burn down their house, New Orleans police said. A fire was reported at the address "moments later," police said.The mother was not at the home when the fire started but was on her way there, according to police."He's going crazy," the mother said in a 911 call released by the Orleans Parish Communications District. "I'm at work. I'm trying to hurry up and go there right now."The mother told the 911 operator that her ex-husband was screaming and "said he's about to burn the house" while begging for police to hurry.First responders found the house engulfed in flames, police said. A 5-year-old girl and an 8-year-old boy were rescued from the home by firefighters, but were pronounced dead at a hospital about an hour later. The body of a 3-year-old boy was also recovered from the home and he was pronounced dead at the scene.Washington was identified as the prime suspect in the homicides, police said. His car was found earlier Wednesday in Gretna, partially submerged in the Mississippi River, police said. He was later apprehended on the I-610 after allegedly attempting to flee by jumping off the overpass and taken to a local hospital for treatment of injuries sustained in the fall, police said.Washington has been charged with three counts of second-degree murder, three counts of second-degree cruelty to a juvenile and one count of aggravated arson, police said. The charges could change, Lubrano said.The children's cause of death will be determined by the coroner.What sparked the fire is currently under investigation, Lubrano said. Police are also reviewing the parents' custody arrangement and whether officers have responded to the home before."Collectively we are outraged, we are disappointed, we are deeply saddened," interim Chief Kirkpatrick said while surrounded by members of the community during the briefing."The person responsible will be held accountable," she added.。    2019年7月25日，星际荣耀公司的双曲线一号遥一火箭发射成功，也是我国民营航天首次成功入轨，但没想到，接下来的三发均未能取得成功。2022年5月13日，双曲线一号遥四火箭在我国酒泉卫星发射中心点火升空，火箭飞行异常，发射任务失利。据官方消息，2022年10月18日，星际荣耀公司组织召开了双曲线一号遥四运载火箭飞行故障归零评审会，与会专家一致认可飞行故障原因和归零措施的有效性，完成归零工作闭环。经查，双曲线一号遥四运载火箭飞行故障定位于多余物导致箭上2000N姿控发动机燃料路主阀关闭不严，出现燃料泄漏，提前耗尽，姿轨控动力系统失去控制能力，三级飞行段姿态超差，触发箭上主动安控条件，火箭执行自毁指令，飞行失利。星际荣耀表示，多余物问题导致火箭飞行试验失利，付出了惨痛的代价。目前，星际荣耀在全面落实故障改进措施的基础上，正在开展后续火箭研制生产，将认真整改，全力保障后续任务成功。另外，星际荣耀的双曲线二号验证火箭，已于今年6月22日在酒泉卫星发射中心圆满完成液氧液氮全流程合练工作，向可重复使用运载火箭研制成功迈出关键的一步。

B | 此次合练，双曲线二号验证火箭试验队按照首飞试验要求，开展了加注准备、加电测试、液氧液氮加注、预冷演练、紧急泄出演练、模拟发射和回收处理等工作，完成了双曲线二号验证火箭加注、发射、着陆回收全流程操作演练，验证了加注、发射、着陆回收处理流程的正确性和系统间工作的协调性，箭上和地面相关产品在低温环境下的工作适应性，加注供气系统功能与火箭的匹配性，试验使用的技术文件和操作规程的正确性和完整性，完成了对加注、发射、着陆回收处理流程中各项工作时间的评估，为双低温可重复使用火箭垂直起降（VTVL）飞行试验打下了坚实基础。
