Китай провел испытания вращающегося детонационного двигателя на высоте 20 км
Частная аэрокосмическая компания Space Transportation, или Lingkong Tianxing Technology провела испытания вращающегося детонационного двигателя. Поднявшись на высоту 20 000 метров, летательный аппарат с экспериментальным двигателем JinDou400 развил скорость 5000 км/ч. Если таким двигателем оборудовать пассажирский лайнер, то он долетит от Пекина до Нью-Йорка за час с небольшим.

The S&P 500 fell 1.3% to 4,204.36, and the Dow Jones Industrial Average was down 0.7% to 32,943.33. The Dow posted a fifth straight weekly loss — its longest losing streak since 2019. The Nasdaq Composite tumbled 2.2% to 12,843.81. Though all three indexes opened in the green, stocks took a turn after a new report showed U.S. consumer sentiment deteriorated more than expected in early March as consumers' inflation expectations soared to the highest since 1981. The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. I want a secure messaging app, should I use Telegram? For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. He said that since his platform does not have the capacity to check all channels, it may restrict some in Russia and Ukraine "for the duration of the conflict," but then reversed course hours later after many users complained that Telegram was an important source of information.
