Rocket Factory Augsburg (RFA) test fire failure.

 

 

...pretty fireworks.

Fire cause: propellant leaking from engines after shutdown, the pad did not have its own water supply and the tanks ran dry. Other suppression was inadequate.

Apparently a COPV (carbon over wrapped pressure vessel) used for helium failed, taking out propellant lines - which cascaded. The failure was due to mishandling by the assemblers. 

 They will do two more flights of this transitional design, then they switch to the all new V3. 

It being based on 1930s comic book rockets, no. It's based on sideways reentry concepts by NASA going back to the 1960s. One of those turned into the space shuttle, others have been explored by everyone from the Chinese (LONG MARCH 9) to Blue Origin and Relativity Space.

Most differ from Starship mainly in fin placement and shape, not sideways reentry which makes sense if you actually think about it. The idea is to present the largest possible surface area to minimize local heating, and the fins are not airfoils they are drag brakes. Think about how a  skydiver uses his hands & legs to steer.

    • Classic 7 is Windows 10 LTSC cosplaying as Windows 7

      By Ixion · Posted

      Given only Volume license customers and specific resellers can obtain the LTSC versions legitimately it seems likely that this has been tinkered with quite a lot!
    • Apple CEO Tim Cook confirms looming price hikes due to memory shortages

      By Hamid Ganji · Posted

      Apple CEO Tim Cook confirms looming price hikes due to memory shortages by Hamid Ganji Image via Apple Memory and chip shortages have led to significant price increases for electronics over the past year, and it seems that more hikes are on the way for upcoming smartphones and computers. Apple CEO Tim Cook has confirmed that the company is planning to increase the prices of some of its products due to the ongoing memory and storage shortages. In an interview with The Wall Street Journal, Cook confirmed the looming price hikes for Apple’s future products, adding that “Unfortunately, price increases are unavoidable.” He also said the company is doing its best to “mitigate the huge increases that are being passed to us, and we’ve been trying to shield our customers from the increases, but the situation has become unsustainable.” The Apple CEO also noted that the allocation of a large portion of memory chips to AI companies has contributed to shortages in the market, resulting in lower supply at a time when demand for devices remains high. “We definitely need memory pricing and supply to return to reasonable levels for consumer products. That’s the bottom line,” Cook said. Cook also added that Apple is ready to use its vast cash reserves to help boost supply in the market because additional production capacity is needed. While he declined to specify how Apple plans to do that, he said the company will not build its own memory and storage factories despite its financial resources and silicon expertise. Cook did not provide further details on the scale of the price increases or which Apple products would be affected, though iPads and Macs could see higher prices sooner than other products. Apple’s next product launch event is scheduled for September, when the company is expected to unveil the iPhone 18 Pro, iPhone 18 Pro Max, and its first foldable iPhone. It remains unclear whether the upcoming iPhones will be affected by the price increases, but given the current memory shortage, higher prices seem increasingly likely. There is currently no clear timeline for the end of the memory shortage. Samsung, one of the world’s three largest memory chip manufacturers, recently said the shortage could persist for several more years.

      Downloads does not equal actual usage, even less when the app is pre-installed in some Galaxy phones.

      +1000 to this, don't understand why they added that margin around the top bar, even the close button is a PITA to click without aiming. Ofc, this is just preview and hopefully they will revert such odd UX decision before hitting final version.
