一 |     The Israel-Hamas conflict is taking a "horrendous toll" on families, humanitarian organizations like UNICEF decried this week, amid reports of the slaughter and kidnapping of children and attacks on civilian infrastructure that have killed, injured or displaced the most vulnerable.In the days since Hamas' surprise assault on Israel, images from both regions have shown crying children running through the street and cowering in bomb shelters after airstrikes. In Gaza, the bodies of dead children killed in shelling were covered in blankets and carried by their fathers in funeral processions. In the kibbutz of Be'eri, one of the largest in Israel, more than 100 bodies of Israeli citizens were discovered on Monday, with women, children and the elderly "brutally butchered," the Israel Defense Forces said. Israeli children have also been among those reported kidnapped by Hamas terrorists.

A special edition of "20/20" at 10 p.m., Wed., Oct. 11, on ABC looks at life under threat in Israel and Gaza and how this attack is different from what we’ve seen in this region in the past.

"Nothing justifies the killing, maiming or abducting of children -- grave rights violations which UNICEF wholeheartedly condemns. Yet less than 72 hours after the outbreak of horrific violence in Israel, reports indicate that grave rights violations against children are rampant," UNICEF Executive Director Catherine Russell said in a statement on Monday. "Many children have been killed or injured, while countless others have been exposed to the violence."According to Palestinian authorities, 900 people have been killed in Gaza so far -- including 260 children and 230 women. The number of children killed in Israel is unclear; at least 900 people have died and 2,600 others have been injured, officials said, though did not specify how many were children. Prime Minister Benjamin Netanyahu said in a speech Monday that among the "atrocities" committed by Hamas, children have been "executed with the rest of their families."In remarks at the White House Tuesday, President Joe Biden described "Hamas' bloodthirstiness" as reminiscent of ISIS rampages -- including "stomach-churning reports of babies being killed."At least 100 civilians and soldiers have also been taken hostage by Hamas militants, Israeli officials said. Hamas leaders on Monday threatened to begin killing hostages one by one and filming the executions if their demands are not met.Among those abducted were 12- and 16-year-old brothers, their mother told ABC News. The woman, who asked not to be identified for security reasons, said the boys were abducted Saturday by Hamas militants who burst into a safe room at their father's home on a kibbutz near the Gaza border."I want the world to demand the release of those innocent civilians. I want these children and women and babies back home, and I want my children back home," the mother said. "I can't take a shower without thinking of them being held hostage in some dirty pit somewhere. I can't eat, I can't sleep. I don't think human beings treat people like this. I'm sorry. I want the world to know, to demand those hostages to be returned to their homes."In response to the assault, Israel on Monday carried out a "complete siege," cutting off power and blocking food and water from being delivered to the Gaza Strip -- where, according to the CIA, nearly 40% of the population of 2 million is under the age of 15.UNICEF is "extremely alarmed" about those measures, spokesperson James Elder said at a press briefing Tuesday in Geneva."This will add another layer of suffering to the existing catastrophe faced by families in Gaza," Elder said. "Depriving children of access to food and essential services puts their lives at risk, as do attacks on civilian areas and infrastructure."According to UNICEF, 80% of those who live in the Gaza Strip rely on some form of humanitarian assistance.The conflict has led to "grave humanitarian consequences," Lynn Hastings, a humanitarian coordinator for the Gaza Strip for the United Nations Office for the Coordination of Humanitarian Affairs, while calling for all parties to abide by international humanitarian law."Civilians, especially children, medical facilities, humanitarian personnel health workers, and journalists must be protected," Hastings said in a statement Tuesday. "Captured civilians must be released immediately and unconditionally."UNICEF has also called on all parties to protect children from harm, in accordance with international humanitarian law."I remind all parties that in this war, as in all wars, it is children who suffer first and suffer most," Russell said.。

二 |     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。

三 | 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。

四 | 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。
