航天X神龙飞船首次试飞及跳票：不早于2月_我的网站
A | 1月11日，美国国家航空航天局在一篇博客中称，第一艘无人驾驶的“神龙”宇宙飞船的试飞时间不会早于今年2月。上一个目标日期是1月17日，但马斯克在1月初的推特上说，考试前还有一个月的时间。作为与美国航天局合作的商业项目的一部分，SpaceX和波音公司将把美国航天局的宇航员送到国际空间站。明年将进行多项关键测试。spacex的demo-1飞行测试将是第一个测试载人飞船，但它不会载人。美国航天局在其博客中表示，美国航天局和SpaceX现在计划在2月前实施demo-1，以完成对载人龙舟的硬件测试和联合评估。 Stockholm, Oct 10 (UNI) The Royal Swedish Academy of Sciences announced Monday that three US-based economists won the 2022 Nobel Memorial Prize in Economic Sciences “for research on banks and financial crises”.
The winners are Ben Bernanke, former head of the US Federal Reserve and currently with the Brookings Institution in Washington DC, Douglas Diamond of the University of Chicago and Philip Dybvig of Washington University in St. Louis, Missouri. The winners share a prize of about $900,000.
The nobelprize.org put out a release saying:
"Their discoveries improved how society deals with financial crises
"This year’s laureates in the Economic Sciences, Ben Bernanke, Douglas Diamond and Philip Dybvig, have significantly improved our understanding of the role of banks in the economy, particularly during financial crises. An important finding in their research is why avoiding bank collapses is vital.
"Modern banking research clarifies why we have banks, how to make them less vulnerable in crises and how bank collapses exacerbate financial crises. The foundations of this research were laid by Ben Bernanke, Douglas Diamond and Philip Dybvig in the early 1980s. Their analyses have been of great practical importance in regulating financial markets and dealing with financial crises.
"For the economy to function, savings must be channelled to investments. However, there is a conflict here: savers want instant access to their money in case of unexpected outlays, while businesses and homeowners need to know they will not be forced to repay their loans prematurely. In their theory, Diamond and Dybvig show how banks offer an optimal solution to this problem. By acting as intermediaries that accept deposits from many savers, banks can allow depositors to access their money when they wish, while also offering long-term loans to borrowers.
"However, their analysis also showed how the combination of these two activities makes banks vulnerable to rumours about their imminent collapse. If a large number of savers simultaneously run to the bank to withdraw their money, the rumour may become a self-fulfilling prophecy – a bank run occurs and the bank collapses. These dangerous dynamics can be prevented through the government providing deposit insurance and acting as a lender of last resort to banks.
"Diamond demonstrated how banks perform another societally important function. As intermediaries between many savers and borrowers, banks are better suited to assessing borrowers’ creditworthiness and ensuring that loans are used for good investments.
"Ben Bernanke analysed the Great Depression of the 1930s, the worst economic crisis in modern history. Among other things, he showed how bank runs were a decisive factor in the crisis becoming so deep and prolonged. When the banks collapsed, valuable information about borrowers was lost and could not be recreated quickly. Society’s ability to channel savings to productive investments was thus severely diminished.
"The laureates’ insights have improved our ability to avoid both serious crises and expensive bailouts,” says Tore Ellingsen, Chair of the Committee for the Prize in Economic Sciences.
The Nobel Memorial Prize in Economic Sciences was not included in Alfred Nobel's will, voanews.com reported.
It was established by the Swedish central bank in 1968 — and is officially the "Sveriges Riksbank Prize in Economic Sciences in memory of Alfred Nobel" to mark the bank’s 300th anniversary. It was first awarded in 1969 and has been funded by the bank since then.
UNI ING。新的发射日期将在与多个机构协调后确定。目前，美国政府已经关闭了许多政府部门，因为在墨西哥南部边境地区修建隔离墙，许多美国宇航局项目和机构也受到关闭的影响。美国航天局官员没有说这次试飞是否与美国政府有关。
