Not yet, but I'm sure that idea is being ... "floated". :rofl: (Sorry, I had to.)

Can you please "expand" on what that would entail?

 

We should know more after 2 ... they're holding media conference at 2 EST to clear the "air" and provide an update.

 

...thank you.  I'll see my way out.

Certainly; but all it would accomplish would be to "inflate" previous comments. :rofl:

 

... aaand there's Security to show me to the door too.

NASA is being safe and will air're on the side of safety....OK, now stop.....

 

Actually, I have heard mention that a few factors are being checked, such as pyro cutters that didn't, stuck strap, and unlikely material friction, due to composition, material mentioned by Doc before, forgot the name, like kevlar.

 

For safety, EVA would be definitely last, flinging people into orbit frowned on. We have the arm and Dextre for that. One will be surprised at what it can do, even repair itself (ISS thread).

 

As mentioned above, NASA  will (expand) hear something at the press briefing.

 

:D

So, was listening and they'll try to expand it again tomorrow.  No time yet ... but they plan on live-streaming it again and will release time later.  Didn't hear any discussion about space walks.

From press conference...rough summary

 

The pressurization constraints are developed by NASA for station safety, therefore using low pressure expansion curve for station safety. This is in addition to Bigelow safety constraints.

 

Early tomorrow, the expansion routine will occur again. If a no go, it will wait till mid/end week for possible robotic platform involvement.

 

Pyro cutters worked, straps were cut and bulkhead bolts were released. They are now dealing with expansion friction and the use of a simulation curve that may not align with actual deployment.

NASA will televise the operation tomorrow, once times are finalized and notices for viewing are released.

 

10% pressure levels, as compared to operational pressure, is being used. NASA and Bigelow are not too worried nor surprised. Station safety being paramount, a slow curve is being used.

 

Fabric and soft goods do have a memory and some adherent forces, and was expected.

 

Storage was slightly longer than 1 year (15 months), but the materials will relax with time. This is a demonstrator mission and will be a learning mission.

 

NASA had changed original plan, where Bigelow onboard tanks expanded unit. Here, Station air source is being used, it is a more metered method for safety. 

 

By overnight, there was approximately 6 inches of expansion longitudinally and axially.

 

We'll see what happens tomorrow, but definitely no major concern.

 

Material friction is the issue. Will just require time.

 

EVA is definitely not in the plan, will use robotic arm if warranted.

 

Bigelow has no concerns about module integrity, with respect to rapid deployment. It is being done this way for station safety, safety is with respect to coupling of modules, node 1 and node 3, node 3 could break off with severe force, and not likely to happen, but have to err on the side of safety.

 

:D

Like watching paint dry...but expected expansion so far. :)  Will be nice to have a time lapse on this.  They are taking a 40 minute break (KU gap) ... resuming in about 40 minutes or so (:35 past the hour).

They are really expanding now...thought they were going to shut it down until tomorrow.  Anyway, they've been doing 8, 10 and 14 second bursts of air vs. the 1 or so seconds earlier that they've been doing.  Sounds like popcorn popping in the microwave. :)

This kind of reminds me of how long it takes me to blow up pool floats. :)  Speaking of...Bigelow Aerospace should design the next one to look like a gator.  Concept art below.

15 seconds of air ... more popcorn sound which sounds awesome.

Edit...Holy crud...now 30 seconds of air. :)  May turn up my speakers and see if my dogs look at the microwave.

Here is a link for a pdf, saw this on NSF....

 

Modeling of Local BEAM Structure for
Evaluation of MMOD Impacts to Support
Development of a Health Monitoring System

 

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20160001632.pdf

 

It shows how the layers are constructed on BEAM....tough little unit, she'll be fine up there.    :D

    • Rockstar confirms Grand Theft Auto VI pre-orders begin next week, unveils cover art

      By LoneWolfSL · Posted

      Rockstar confirms Grand Theft Auto VI pre-orders begin next week, unveils cover art by Pulasthi Ariyasinghe The release date of Grand Theft Auto VI has moved quite a lot since its original announcement in 2023, but it finally looks like the game has found its final launch slot. Rockstar today had a new video upload on its YouTube channel, and while it wasn't a new trailer for the game, the company revealed two things. This was the pre-order kickoff date for Grand Theft Auto VI as well as the game's official cover art. The company revealed that June 25 is when fans of the series will be able to pre-order their copy of Grand Theft Auto VI. Pre-orders will be available both digitally and in retail stores. The newly unveiled cover art shows off the two new protagonists, as well as a few more characters that are probably vital to the campaign storyline. Shots of vehicles players can use like a light helicopter, motorcycle, sports car, and speed boat are also seen here, alongside a shot of a crocodile. "Jason and Lucia have always known the deck is stacked against them," says Rockstar describing the campaign's protagonist duo. "But when an easy score goes wrong, they find themselves on the darkest side of the sunniest place in America, in the middle of a conspiracy stretching across the state of Leonida — forced to rely on each other more than ever if they want to make it out alive." Grand Theft Auto VI is coming to Xbox Series X|S and PlayStation 5 on November 19, 2026. A PC version has not been confirmed yet, though it's expected by many to land after the console release. When asked about this, the Take-Two CEO says it considers the core audience for the Grand Theft Auto franchise to be on consoles.

    • How to fix a Secure Boot error on Windows 11: No boot device found.

      By +Warwagon · Posted

      In rare occasions when you turn your computer on you will be greeted with a Secure Boot error followed by the message "No boot device found" If you go into the UEFI and disable Secure Boot the system boots up just fine. Below is a method I found online to fix the issue Disable Secure Boot and boot into Windows (If Bitlocker is enable you'll have to go to https://aka.ms/myrecoverykey on another device to find your bitlocker recovery key). Find a flash drive and make sure it's formatted Fat32 Create a folder on the flash drive called EFI and a subfolder inside EFI called BOOT On your computer navigate to C:\windows\boot\EFI Copy the file SecureBootRecovery.efi to your flash drive\EFI\BOOT Now reboot the computer and tell the computer to boot off that flash drive. You should see a black screen with some text telling you it has repaired Secure Boot Turn Secure Boot back on and reboot and your computer should boot normally.
