Bigelow Tests Life Support System

WASHINGTON ? Bigelow Aerospace completed an initial closed-loop test in March of a prototype environmental control and life support (ECLS) system designed to support extended crew stays inside the inflatable habitats the company is building to provide research facilities and hotel accommodations in space.

The March 31 demonstration was conducted inside the company?s North Las Vegas headquarters in a newly constructed test chamber, according to Eric Haakonstad, Bigelow Aerospace chief engineer. He said the test involved locking three Bigelow engineers inside the 180-cubic-meter structure for about eight hours, during which they performed a variety of tasks that demonstrated the ECLS system?s ability to control temperature, humidity, pressure, oxygen content and the removal of carbon dioxide and trace-gas contaminants from the environment.

Haakonstad said the initial checkout of the test facility is the first of many demos planned over the next year to simulate and test ECLS systems in support of long-duration crew stays in orbit. He said within the next couple of months Bigelow Aerospace plans to conduct a 30-hour demonstration of the ECLS system followed by another lasting up to a week.

He said both the ECLS system and its test chamber were built in-house, giving the company more control over system development.

Haakonstad said Bigelow?s ECLS design incorporates lessons learned from systems used aboard platforms including the international space station, the Mir space station, the space shuttle and, to a lesser extent, the Orion crew capsule currently under development by NASA.

?We?re not reinventing the wheel here,? Haakonstad said. ?All we?re trying to do is take the technology development that our tax dollars through NASA have developed and package them into a more producible form factor. We?re not trying to be cutting edge in terms of technology; we are trying to be cutting edge in terms of affordability and availability and ruggedness.?

However, unlike ECLS systems designed for short-term trips between Earth and the space station, Bigelow?s ECLS system is designed to support long-duration missions on orbit.

To be totally honest I'd be more excited if they turned the idea of the inflatable station into a moon base or something awesome like that; if you made a facility huge enough on the moon it should be self sustainable. Are there any plans of using the idea on a moon base?

Absolutely!! Bigelow has a whole set of patents for a landable base complex to be assembled at EML-1, a gravitational equilibrium point between Earth & Moon that's a perfect place for space docks, fuel depots etc. More Bigeliw info & pics in this thread -

he deserves these honors, i'd name a few characters/ships after him were i a notable sci fi writer/hollywood bigwig...

and yes, Doc has been telling us about their moon base plans for a while now. i really hope they become reality by the end of this decade.

All at Google Patents - search for "Robert T Bigelow." these are the applications.

When looking at the base remember that while the hab walls are expandable & flexible at first, they are rigid after deployment. The habs also have metal cores and bulkheads at either end, making the whole structure very strong. Docking them to the solid metal hub/propulsion buses, which use the same attachment used at ISS, makes for a very solid structure.

Basic satellite bus (habitat)....

Impact shield....

Landable base....

Emergency safe haven....

Biomass disposal....

Bigelow has estimated each BA-330 module would cost ~$100M. As to the cost of the propulsion bus/hubs - that's pure guesswork, but guess high at the same as a module and you have a (probably high) cost of ~$1B for the base plus launch costs of $125M per Falcon Heavy which could well do two-fer launches.

Now consider that NASA spent ~$40B on the Constellation program over the last 6 years and have nothing to show but a cancelled program and an Orion spacecraft that may never fly, especially if Dragon works as advertised.

jesus, we could have had an entire city up there now for 40 billion...what were they thinking? or is this the true, ugly face of corruption? thanks for the figures, that's quite economical, really. i have no idea why we're not doing it then. you want to tell me we could go to Mars and establish an outpost there for like $20 billion or so? and we're still not doing it?

If we had used $0.02 worth of common sense we could have been on Mars 20+ years ago. More numbers for you -

US cost of ISS: $100 billion

2x larger volume than ISS Bigelow station: less than $1 billion

Shuttle flights: $1.5 billion, each

Falcon 9 flights: $56 million

Cost of Dragon fligyr: $133 million

Falcon Heavy flights : $80 - $125 million (2x the cargo of shuttle)

and a few examples of what $600 million pays for -

Ares I-X test flight: not light hardware. It only tested the shape & failed

Launch tower for Ares 1-X

What Congress spent on Constellation after it was cancelled

TOTAL development cost of Dragon & Falcon 9

They don't, other than blaming previous administrators, Congress/s, presidents etc. etc. etc. going back 40+ years.

Fact is a lot of things contributed including not being willing to try the new - especially if it meant a congressman/senator's district losing an existing contract. This is why Congress is demanding a Shuttle-derived heavy launcher instead of opening it up to competition - ATK (the makers of the shuttle's solids), the NASA centers that would be involved and such are in the districts of very influential representatives. Some of it was just bad decision making.

this is the truth i always try to lie to myself about, thanks for reminding me of the reality of things. progress is at the mercy of idiots and short sighted con artists. i really hope this will change soon. i hope it will be realized by all that there's endless wealth to be made from space exploration, and then greed will take us forward. i know, sounds evil, but then it took just that to get humans to pretty much do anything of any material value ever since we left the African veldt all those many millennia ago...

ISDC = International Space Development Conference at the Von Braun Center in Huntsville, Alabama (near a NASA center)

These are the slides from their presentation -

http://images.spaceref.com/news/2011/isdc.bigelow.pdf

Their new 180,000 sq/ft factory is almost finished, and they've reduced the launch mass og the huge BA-2100, now known as Olympus, to 65 metric tons from the originally quoted 100 metric tons. This puts it wjthin the margins of a Falcon Heavy with a Raptor (hydrogen) 2nd stage or NASA's proposed SLS system.

Also interesting is their concept for NASA's Plymouth Rock asteroid mission; a BA-330 as the hab, a crew return vehicle and one of their big hub/propulsion modules for a crew of 4. Nice....

Here's another number for you; this 180,000 sq ft exapasion will take their total up to 370,000 sq ft

This includes offices, R&D, factory space, testing, vehicle integration and a large mission control center, which they had to build early because of having 2 Genesis modules already in orbit as testbeds. Yup, like SpaceX they're already flying.

    • Thanks
    • I actually got to use one of those so called "backup codes" once. It was for a customer, I choose the backup code option, and by the grace of god, they actually hade them printed out. Imagine my surprise, when after using the backup code, Google then told use we had to enter a code they just sent to the gmail address we currently did not have access to. I was not amused, Google backup codes should be the end all get out of jail free card, because you had to have access to the account to even get them.
    • On the topic of being locked out of a service. Recently two different friends of mine got locked out of their Google accounts. Both were hack attempts and one of them is waiting 30 days before he can get back in. He had backup codes and MFA but not a passkey. It was a browser token hack. Anyhow he has to wait 30 days for the dispute or whatever to end. The other person only had a password and is screwed losing all of the email, docs and years of photos. Google won’t help her at all. Her fault because she had no backup/recovery setup. Enable passkeys if possible. Also do NOT use browser based password managers. If using a cloud service make sure it is one you can fully sync to one of your devices so you can back it up. Like a PC or Mac with some backup drive plugged into it. Google is the worst to use IMHO. You can’t sync your photos at all. You have to use the “Take Out” service which is manual and takes days. That service strips the meta data from your photos. Also Google Docs synced to a device are useless without a Google accounts. MS Office/Libre Office is not going to open a link to a Google doc to a dead account.
    • Why you need to take back control of your synced passwords and how to go about doing that by Paul Hill Credit: Pixabay Last month, when Google decided to introduce daily and weekly caps for Gemini, it reignited an anxiety of mine, that you can’t really depend on service providers to maintain features forever, and it got me looking into free software (as in freedom) in other areas too. One app I quickly came across was KeePassXC on desktop and KeePassDX on Android as an alternative to password manager lock-in within the Chrome or Firefox ecosystems. I personally like to switch around with browsers, and using either password manager is inconvenient, so something like KeePassXC was interesting to me. The main issue with it now is syncing; I was not sure how to do that. After a bit of research, I came across Syncthing, a tool I was vaguely familiar with but had never used because it seemed complicated. However, I was completely wrong, and honestly, I think everyone should use it if they use multiple devices. It essentially lets you share folders peer to peer across all of your devices, no cloud services that you don’t control necessary! And it was fairly simple to set up, if not a bit clunky. Since setting it up, I’ve also started using Syncthing to back up other apps too, so don’t think it’s limited to just saving password databases. You can use it for pretty much anything you use Dropbox or Google Drive for. Before continuing to talk about those apps a bit more, let’s walk back a bit and talk about browser sync. Ever since the late 2000s and early 2010s, really, since we have been using smartphones, browser sync has been a necessity of life. I don’t know about you, but I have hundreds of passwords saved. For the most part, they’re all unique, so I don’t remember them and rely on software to manage them for me. Until recently, I’ve relied on password managers in Chrome and Firefox, but what I always found annoying was that it can be hard to transfer them between browsers. Sure, on Windows it is simple enough, but on Linux, exporting bookmarks has been temperamental. It works OK nowadays, but not too long ago, Chrome required you to enable exporting passwords in chrome://flags. The situation is even worse on mobile; there is no exporting or importing of passwords of any kind. You literally have to do it on a desktop, which is incredibly annoying in our mobile-first world. Sync also lets us take out bookmarks, history, tabs, and autofill data easily. To enable sync, it’s just a matter of signing into the browser once, and it handles the rest. It’s nice and easy. Obviously, all this has some issues, including those I’ve outlined above about it being hard to transfer data between browsers, but also things such as account suspension, lost account passwords, and other lock-in mechanisms, such as passkeys, being tied to a specific browser. On a sidenote, I have just removed all of my passkeys because they can make it harder to move browsers. I think the biggest threat to your synced passwords, especially if doing this with Google, is having your account suspended. I don’t ever expect mine to be suspended, but you do hear horror stories on Reddit where people lose access to their Google accounts. Imagine if you have hundreds of passwords, then suddenly lose access to them because Google froze your account, what would you do? So yes, it can be nice to use these syncing services for their convenience, but they also have risks. You may have seen me going on about free software quite a bit in my editorials. It’s essentially a concept championed by the Free Software Foundation. It’s software under particular licenses that grant you four freedoms: run the program for any purpose (0), study and change the source code (1), redistribute copies to others (2), and the freedom to distribute modified copies to others (3). For example, if there is an app I use and one day it gets abandoned by the developer, I can keep running it or even clone the software and continue developing it. Look at the myriad of cool services Google has run over the years before killing them. You can’t take the source code for those because they are proprietary, for the most part. Both KeePassXC and Syncthing are free software, so I get the freedoms listed above. In my use case where I’m syncing a database full of my passwords, I also get proper ownership over my data, there is no losing access to the database due to a frozen account, I can access the code of the tools I’m using, and I can get support from real people online if I run into issues, rather than having to consult a vague help page from an opaque company. With the KeePassXC password manager, you create a .kdbx file, which is what will be synced between devices. KeePassXC has cross-platform apps and also has browser extensions so that the browser can fetch passwords from the database once it is unlocked. Meanwhile, Syncthing is a peer-to-peer file sync tool where you can select folders to sync between your devices. Just pop files in the folders you choose, and then they will be available across your other devices whenever they come online. Syncthing is resilient as it works over both LAN and the internet and only ever sends content between your devices, never to a third-party server somewhere else. By combining these two pieces of software, you can essentially replicate the browser sync functionality. I have had a weird, conflicting issue where a new file is appearing, but it doesn’t seem to be impacting my main password database, which is updating between devices just fine. If you want to get a setup similar to what I have, you will need to go here to download KeePassXC for your computer. Once you have that, you will need to download your passwords from your web browser to a CSV file. In Chrome, you can type chrome://password-manager/settings into the URL bar, and you should see an option to download your passwords under Export Passwords. This will give you the CSV file you need for importing into KeePassXC. If you use a different browser, just use a search engine and type “browser-name export passwords” and muddle along. In KeePassXC, you’ll want to press Import File from the home screen, select the CSV file, and create a new database from it. On one of the screens of the wizard, there will be a Title field with a drop-down selected to none. Change this to Title and continue. You’ll select a name for the database, the encryption level (the defaults are fine), and then you will pick a password. I would choose four unrelated words that are easy for you to remember, as you’ll be typing them fairly often to access your passwords. When you have all your passwords in your new database, you will want to set up the browser extension so that your browser can fetch passwords from KeePassXC. Rather than explain how to do that here, refer to KeePassXC’s guide on how to set it up properly. Once you’ve got that set up, you want to install KeePassDX on Android. You can grab it on the F-Droid store and the Google Play Store. For iPhone users, there are other .kdbx-supporting apps, but I haven’t tried any of them, so have a look around and use what suits you. Once you have that done, you will want to install Syncthing on your computer and find a third-party app for your mobile device. On Android, I use an app called BasicSync; there are also options for iOS, but again, I’ve not tried these. Once you’ve got SyncThing, you’ll want to set it up and connect all of your devices together and share a folder between your gadgets. PCWorld has a good tutorial on setting up a synchronized file between your devices using SyncThing. Once you’ve set it up, congrats, you’ll never have to touch that stuff again except for adding or removing devices. I’ll be honest, I didn’t particularly like setting up Syncthing. It didn’t take me a massive amount of time, but I think I had to check online because I found it a bit confusing. That said, I’ve had it running for several weeks now and never need to touch the Syncthing settings, so that’s very nice. I also mentioned a conflicting file. I’m not sure why this is appearing, but the main .kdbx file seems to be updating and syncing just fine. What’s nice is that both KeePassXC and Syncthing are free software, so they won’t just vanish one day; you can take the code and fork the project or use a range of alternative implementations that others have made. It’s also nice that it works over LAN, so even if your ISP is having problems, your passwords will still sync. One area where you will want to be a bit more careful with this setup is if you only have one device. I am OK because I have a computer and two phones, all synced up. If you just have one device, you will probably want to store a backup of your .kdbx file somewhere else. Obviously, you’ll also want to remember your password really well, too. If you get locked out, it's game over. Overall, if you want to take back control of your computing from big tech, taking control of your passwords is an important part of this. You don’t need to immediately clear out your browser’s password manager; try running KeePassXC and the password manager concurrently for a while to see if you run into any problems. If you do try this out, let us know some other creative ways to use Syncthing. I haven’t really come up with a solution about what to do with my bookmarks, for example.
