一 | The Powerball frenzy continued on Wednesday as numbers were drawn for the $1.73 billion jackpot.The winning numbers drawn for the jackpot prize were: 22, 24, 40, 52, 64 and red Powerball 10. The power play was 2.One ticket had all the numbers. It was sold in Frasier Park, California, which is located between Los Angeles and Bakersfield in Kern County.The grand prize, which had an estimated lump sum payout of $756.6 million, continued its ascent through billion-dollar territory after no ticket matched all six numbers drawn on Monday night, Powerball said.Monday's jackpot was the third-largest prize in Powerball history, officials previously said, making Wednesday's prize now the second-largest.Florida had at least one ticket on Monday that matched five and got the power play number, all adding up to a $2 million win. There were match five winners who won $1 million in California, Indiana, Oregon and Virginia.The last billion-dollar Powerball prize -- the jaw-dropping $2.04 billion -- was won in California in November of last year. The next largest prize -- $1.586 billion – was won in Jan. 2016 in California, Florida and Tennessee.Lottery officials said that while the odds of winning the big jackpot may be astronomical, the chances of winning a smaller prize were much better at 1 in 24.9.Jackpot winners can either take the money as an immediate cash lump sum or in 30 annual payments over 29 years. Both advertised prize options do not include federal and jurisdictional taxes.Powerball tickets cost $2 and are sold in 45 U.S. states as well as Washington, D.C., Puerto Rico and the U.S. Virgin Islands.Powerball drawings are broadcast live every Monday, Wednesday and Saturday at 10:59 p.m. ET from the Florida Lottery draw studio in Tallahassee. The drawings are also livestreamed online at Powerball.com.If no winners are declared from Wednesday night’s drawing, the next one to take place will be on Saturday, Oct. 14.。 欧几里得红外太空望远镜原定于今年从位于法属圭亚那库鲁的欧洲航天港发射升空。但由于ESA中断与俄罗斯航天局的联系，两家机构停止关于从法属圭亚那发射联盟号火箭的合作事宜，俄罗斯航天局还从发射场撤走了87名员工。这一结果导致欧几里得太空望远镜不会搭乘俄罗斯联盟号火箭前往太空。ESA开始寻求用其他火箭发射太空望远镜，其中也包括美国的私人航天企业。据报道，NASA天体物理学部门主任马克·克拉姆平（Mark Clampin）周一在NASA天体物理学咨询委员会一次会议上表示，ESA可能会在2023年中后期用SpaceX的猎鹰9号火箭发射欧几里得望远镜。今年8月，ESA总干事约瑟夫·阿什巴赫(Josef Aschbacher)在接受采访时表示，ESA正在与埃隆·马斯克(Elon Musk)的SpaceX公司就使用猎鹰火箭实施发射任务进行初步讨论。当时，ESA还在SpaceX、日本或印度提供的火箭之间进行权衡。但阿什巴赫说，SpaceX“在这些火箭中更具操作性，肯定是我们正在考虑的备用发射计划之一”。
二 | ESA的另一个选择是法国阿丽亚娜太空公司的重型运载火箭，但新一代阿丽亚娜6号火箭的首飞要到明年才会进行。
三 | 而ESA当下正面临着为联盟号火箭寻找替代火箭的压力。ESA的阿什巴赫表示：“这是一个警钟，让我们意识到我们一直太依赖俄罗斯的联盟号火箭了。
四 | ”欧洲航天局并不是唯一需要寻找替代火箭的机构。
五 | 今年3月份，俄罗斯停止向美国供应火箭发动机，这使得诺斯罗普·格鲁曼公司宣布，将与萤火虫航空公司合作制造一款火箭，从而不再需要俄罗斯火箭发动机。然而，在新火箭准备就绪之前，为了执行与NASA签署的太空货运合同，诺斯罗普·格鲁曼公司不得不用SpaceX的猎鹰9号火箭将天鹅座宇宙飞船送往国际空间站。英国OneWeb公司也被迫与竞争对手SpaceX以及印度空间研究组织ISRO签署了一份合同，计划在今年晚些时候用这两家机构的火箭分6次将第一代互联网卫星送入轨道。从可行性角度来看，SpaceX的火箭最合适替代联盟号火箭，公司也正在接纳来自欧洲市场的新客户。猎鹰9号火箭计划在2022年12月发射SWOT测高卫星，这是NASA、法国航天局、加拿大航天局和英国航天局探测地表水和海洋地形的一项联合任务。今年猎鹰9号还有多达18次发射，而SpaceX的主要精力会放在更多的轨道旅行上。
