Bwahaha ... Williams looks completely nonplussed ... bored, even. "Come on, you weenies. I understand caution, but this is completely ridiculous" is his expression. :rofl: Give 'er six inches of inflation and hold, sheesh. NASA ... ugh. Painfully, maddeningly slow bunch.

Hopefully, better luck tomorrow. There was a slight expansion outwards and radially, but not enough till pressure curve exceeded.

From what I have read, bladders between the "folds" are being inflated for initial expansion. She has been folded and stored for over a year, may just need a tap.

One would think that there is also a direct porting for air into the main chamber as well. But like Doc had mentioned, it could expand violently and cause issues with the ISS seal.

 

/s    As long as it expands into a hab and not this...

Just now, flyingskippy said:

I wasn't able to watch the coverage of BEAM.  Is the problem that it didn't expand enough for the amount of air released or that they released all the air and it didn't expand fully? 

Long story short is it didn't do much of anything. Didn't budge anywhere near what they were expecting it to do. Pressures were higher than expected and amount of expansion was much less than expected also.

They were being over cautious, only applying about .45 psi of pressure because the Genesis 1 & 2 subscale orbital  testbeds expanded in less than 0.25 second. Too big a risk of damage if a larger structure popped that fast. 

 

The last I heard, they were talking about depressurizibg it and possibly trying to loosen the straps.

 

As for why: this thing has been in packed mode for over a year, delayed by the CRS-7 failure and other things. It's possible some stiction has developed between the straps and structure.

    • 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.

      +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.
